FLOAT and DOUBLE data types are data types that can be used to store numbers that can include decimal numbers. They are specifically used to store estimates. What do I mean? I mean that the precision of a FLOAT or DOUBLE value can be lost when doing math. The data types are only capable of maintaining a certain level of precision. The level of precision is usually adequate for most mathematical operations. If you need to store exact data, you will want to look into using the INT or DECIMAL data type instead. The numbers stored in a FLOAT or DOUBLE column are called floating point numbers, we'll see why in just a moment. Why are they called floating point numbers? let's look at a number. 150. This number could be represented as 150, or it could be represented as 1.5 * 10^2, or 1.5e2. With floating point numbers, scientific notation is used. These numbers are called floating point numbers because the decimal can float to different spots as we change the exponent. This means that the data type needs to store the number, how many decimal the number needs moved, and a sign bit. The benefit of floating point numbers is that they allow us to store pretty huge numbers. The down side is that they are not storing values exactly because they are limited in size. This means that only a certain level of precision is to be expected from a floating point data type. If you remember from the video of DECIMAL, precision is the number of digits in a number. As long as the precision for one of these data types exceeds the need for your specific data, the data type can work fine. For example, if you are storing a number like 15 trillion, you don't have to worry as much with precision as your number does not contain a lot of digits. This number can be represented as 1.5 x 10^13. This is a lot different than trying to store 1.5534534534 x10^13. Now we know both of these data types do not maintain a high number of digits correctly, but what is the difference between FLOAT and DOUBLE. The difference is the amount of storage they take up. Float takes up 4 bytes while DOUBLE takes up 8. The benefit in DOUBLE is that because it has more room to store data, it has a higher level of precision and can store bigger numbers. Now, what level of precision can you expect from either of these? FLOAT around 7 and DOUBLE around 15. Now, these data types are obnoxious because the exact values depend on your operating system and in general these monsters cannot be trusted. Especially when you start doing math with different numbers. In general, it is recommended to use the DOUBLE data type to have a higher level of precision and calculations in MySQL are done with DOUBLE. Always remember… prepare for trouble, make it double. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

The DECIMAL data type is similar to the INT data type in that when you use the number for math, it maintains precision. The difference though is obvious in the name. The DECIMAL data type allows for numbers after a decimal point (and before the decimal point). The DECIMAL data type allows us to store what is known as a fixed-point number. A fixed point number is a number that has a specific number of digits available to store numbers in. That means we can't do things like use a DECIMAL data type to store as many digits of PI as possible, because we can't store unlimited digits. We are limited to a certain number. There are two keywords you need to understand when you are working with the DECIMAL data type, precision and scale. Precision is the number of digits and scale is the number of those digits that will come after the radix. You are going to want to provide these numbers when you declare a column of this data type. For example, DECIMAL(5, 2) has a precision of 5 digits and a scale of 2 digits. That means we can store a maximum of two digits after the decimal and four digits total. This gives us a possible range from -999.99 to 999.99 The highest number of digits is 65, and the highest number of digits after the decimal is 30. This data type is also known as DEC, NUMERIC, and FIXED. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_DATE function is used to return the current date in the session timezone. The session timezone is the timezone that the current user is logging in from. This can be different from the database’s timezone. The syntax of the CURRENT_DATE function is: CURRENT_DATE No parameters are needed - just the function name. The function returns a DATE data type, and it includes hours, minutes, and seconds. This is good to know because the default display format for DATE does not include the time component, and it can be easy to forget. It’s different to the SYSDATE function as SYSDATE returns the date in the database timezone, and CURRENT_DATE returns the date in the session time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_DATE will return a date and time that’s 10 hours ahead of SYSDATE. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_DATE - 7 for 7 days ago). For more information about the Oracle CURRENT_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/

Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

#DataTypes In this video we are going to discuss about Data Types. Int data types, Float Data Types, Double Data Types & Char Data Types. C language Lectures.
Views: 146 Focus Group
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

try convert function in sql sql server try_convert try_convert in sql server 2012 try convert sql try_parse vs try_convert sql server In this video we will discuss TRY_CONVERT function Difference between CONVERT and TRY_CONVERT functions Difference between TRY_PARSE and TRY_CONVERT functions TRY_CONVERT function Introduced in SQL Server 2012 Converts a value to the specified data type Returns NULL if the provided value cannot be converted to the specified data type If you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error Syntax : TRY_CONVERT ( data_type, value, [style] ) Style parameter is optional. The range of acceptable values is determined by the target data_type. For the list of all possible values for style parameter, please visit the following MSDN article https://msdn.microsoft.com/en-us/library/ms187928.aspx Example : Convert string to INT. As the string can be converted to INT, the result will be 99 as expected. SELECT TRY_CONVERT(INT, '99') AS Result Example : Convert string to INT. The string cannot be converted to INT, so TRY_CONVERT returns NULL SELECT TRY_CONVERT(INT, 'ABC') AS Result Example : Converting an integer to XML is not explicitly permitted. so in this case TRY_CONVERT fails with an error SELECT TRY_CONVERT(XML, 10) AS Result If you want to provide a meaningful error message instead of NULL when the conversion fails, you can do so using CASE statement or IIF function. Example : Using CASE statement to provide a meaningful error message when the conversion fails. SELECT CASE WHEN TRY_CONVERT(INT, 'ABC') IS NULL THEN 'Conversion Failed' ELSE 'Conversion Successful' END AS Result Output : As the conversion fails, you will now get a message 'Conversion Failed' instead of NULL Example : Using IIF function to provide a meaningful error message when the conversion fails. SELECT IIF(TRY_CONVERT(INT, 'ABC') IS NULL, 'Conversion Failed', 'Conversion Successful') AS Result What is the difference between CONVERT and TRY_CONVERT CONVERT will result in an error if the conversion fails, where as TRY_CONVERT will return NULL instead of an error. Since ABC cannot be converted to INT, CONVERT will return an error SELECT CONVERT(INT, 'ABC') AS Result Since ABC cannot be converted to INT, TRY_CONVERT will return NULL instead of an error SELECT TRY_CONVERT(INT, 'ABC') AS Result Example : Using TRY_CONVERT() function with table data. We will use the following Employees table for this example. SQL Script to create Employees table Create table Employees ( Id int primary key identity, Name nvarchar(10), Age nvarchar(10) ) Go Insert into Employees values ('Mark', '40') Insert into Employees values ('John', '20') Insert into Employees values ('Amy', 'THIRTY') Insert into Employees values ('Ben', '21') Insert into Employees values ('Sara', 'FIFTY') Insert into Employees values ('David', '25') Go The data type of Age column is nvarchar. So string values like (THIRTY, FIFTY ) are also stored. Now, we want to write a query to convert the values in Age column to int and return along with the Employee name. Notice TRY_CONVERT function returns NULL for the rows where age cannot be converted to INT. SELECT Name, TRY_CONVERT(INT, Age) AS Age FROM Employees If you use CONVERT instead of TRY_CONVERT, the query fails with an error. SELECT NAME, CONVERT(INT, Age) AS Age FROM Employees The above query returns the following error Conversion failed when converting the nvarchar value 'THIRTY' to data type int. Difference between TRY_PARSE and TRY_CONVERT functions TRY_PARSE can only be used for converting from string to date/time or number data types where as TRY_CONVERT can be used for any general type conversions. For example, you can use TRY_CONVERT to convert a string to XML data type, where as you can do the same using TRY_PARSE Converting a string to XML data type using TRY_CONVERT SELECT TRY_CONVERT(XML, '[root][child/][/root]') AS [XML] Converting a string to XML data type using TRY_PARSE SELECT TRY_PARSE('[root][child/][/root]' AS XML) AS [XML] The above query will result in the following error Invalid data type xml in function TRY_PARSE Another difference is TRY_PARSE relies on the presence of .the .NET Framework Common Language Runtime (CLR) where as TRY_CONVERT does not.

sql String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). ... The most basic example of a string function is the length(string) function. This function returns the length of a string literal.Scalar-valued UDFs are an easy way to define constant values to use in your database environment. You can pass field values as parameters into UDFs. You can nest scalar function calls. This means that you can pass a call to a scalar-valued function to another function or stored procedure.Numeric functions perform manipulation of numbers that normally are contained in a table column. ... Returns a numeric value, rounded to the specified length or precision. SIGN() SQL server, MySQL, Oracle, PostgreSQL. Returns the positive (+1), zero (0), or negative (-1) sign of a numeric expression.A stored function (also called a user function or user-defined function) is a set of PL/SQL statements you can call by name. Stored functions are very similar to procedures, except that a function returns a value to the environment in which it is called. User functions can be used as part of a SQL expression.Function must return a value but in Stored Procedure it is optional( Procedure can return zero or n values). Functions can have only input parameters for it whereas Procedures can have input/output parameters . ... Functions can be called from Procedure whereas Procedures cannot be called from Function,The CTE was introduced into standard SQL in order to simplify various classes of SQL Queries for which a derived table just wasn't suitable. ... Introduced in SQL Server 2005, the common table expression (CTE) is a temporary named result set that you can reference within a SELECT, INSERT, UPDATE, or DELETE statement.The isDate(string, string) function accepts two string arguments. It takes them, compares the first argument with the second as a pattern and, if the first string can be converted to a date which is valid within system value of locale , according to the specified pattern , the function returns true.printf does the same, treating %s as a pointer-to-string. In C, variables that are arrays become a pointer to the first element of the array when used as function arguments -- so your scanf() sees a pointer to memory (assuming "str1" is an array). SQL - Useful Functions SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. More items... SQL has many built-in functions for performing processing on string or numeric data. Following is the list of all useful SQL built-in functions − SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. SQL MIN Function - The SQL MIN aggregate function allows us to select the lowest (minimum) value for a certain column. SQL - The SQL AVG aggregate function selects the average value for certain table column. SQL SUM Function - The SQL SUM aggregate function allows selecting the total for a numeric column. SQL SQRT Functions - This is used to generate a square root of a given number. SQL RAND Function - This is used to generate a random number using SQL command. SQL CONCAT Function - This is used to concatenate any string inside any SQL command. SQL Numeric Functions - Complete list of SQL functions required to manipulate numbers in SQL. SQL String Functions - Complete list of SQL functions required to manipulate strings in SQL. Returns a Unicode string with the delimiters added to make the input string a valid SQL Server delimited identifier. REPLACE. Replaces a sequence of characters in a string with another set of characters. REPLICATE. Repeats a string value a specified number of times.SQL. Character Functions with Examples. Character functions accept character inputs and can return either characters or number values as output. SQL provides a number of different character datatypes which includes – CHAR, VARCHAR, VARCHAR2, LONG, RAW, and LONG RAW.Aggregate Functions: Aggregates the values and return a single value, below is the list of some aggregate values in sql server. These functions are created by user in the system database, and we have 3 types of user define functions: Scalar Function. Inline Table-Valued Function.
