Oracle 12c R2 Improvements to the Index Usage Tracking Feature
 
41:44
Oracle 12c R2 adds some nice improvements to its index usage tracking feature. With these improvements, it is now easy to find out how many accesses the indexes have received, how many rows have been returned and the most recent time that the index was used. In this webinar OCP DBA John Mullins will explain and demonstrate the behavior changes, enhancements and usage of this feature. This webinar is a subset of the 4 day Oracle Database Performance Tuning course and the 3 day Oracle SQL Optimization for Developers course offered by Themis. This presentation is meant for Oracle development staff and database administrators. It is delivered by Themis instructor John Mullins.

Oracle Tutorial - How to add virtual column in oracle 11g
 
07:41
Hello friends in this video i'm going to demonstrate you how to add virtual column in ORACLE 11g step by step. Oracle 11g supports virtual columns which are derived from the other columns in the table. You can use the virtual columns in your queries, you can index them, you can collect the statistics, etc. There are few restrictions on the virtual columns. You cannot write/insert the data into virtual columns. There is no support for index_organized, external, object, cluster, temporary tables.

How to create Virtual Columns in Oracle Database
 
09:02
How to create Virtual Columns in Oracle Database 12c When queried, virtual columns appear to be normal table columns, but their values are derived rather than being stored on disc. The syntax for defining a virtual column is listed below. column_name [datatype] [GENERATED ALWAYS] AS (expression) [VIRTUAL] If the datatype is omitted, it is determined based on the result of the expression. The GENERATED ALWAYS and VIRTUAL keywords are provided for clarity only. The script below creates and populates an employees table with two levels of commission. It includes two virtual columns to display the commission-based salary. The first uses the most abbreviated syntax while the second uses the most verbose form. CREATE TABLE employees ( id NUMBER, first_name VARCHAR2(10), last_name VARCHAR2(10), salary NUMBER(9,2), comm1 NUMBER(3), comm2 NUMBER(3), salary1 AS (ROUND(salary*(1+comm1/100),2)), salary2 NUMBER GENERATED ALWAYS AS (ROUND(salary*(1+comm2/100),2)) VIRTUAL, CONSTRAINT employees_pk PRIMARY KEY (id) ); INSERT INTO employees (id, first_name, last_name, salary, comm1, comm2) VALUES (1, 'JOHN', 'DOE', 100, 5, 10); INSERT INTO employees (id, first_name, last_name, salary, comm1, comm2) VALUES (2, 'JAYNE', 'DOE', 200, 10, 20); COMMIT; Querying the table shows the inserted data plus the derived commission-based salaries. SELECT * FROM employees; ID FIRST_NAME LAST_NAME SALARY COMM1 COMM2 SALARY1 SALARY2 ---------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- 1 JOHN DOE 100 5 10 105 110 2 JAYNE DOE 200 10 20 220 240 2 rows selected. SQL The expression used to generate the virtual column is listed in the DATA_DEFAULT column of the [DBA|ALL|USER]_TAB_COLUMNS views. COLUMN data_default FORMAT A50 SELECT column_name, data_default FROM user_tab_columns WHERE table_name = 'EMPLOYEES'; COLUMN_NAME DATA_DEFAULT ------------------------------ -------------------------------------------------- ID FIRST_NAME LAST_NAME SALARY COMM1 COMM2 SALARY1 ROUND("SALARY"*(1+"COMM1"/100),2) SALARY2 ROUND("SALARY"*(1+"COMM2"/100),2) 8 rows selected. SQL Notes and restrictions on virtual columns include: 1)Indexes defined against virtual columns are equivalent to function-based indexes. 2)Virtual columns can be referenced in the WHERE clause of updates and deletes, but they cannot be manipulated by DML. 3)Tables containing virtual columns can still be eligible for result caching. 4)Functions in expressions must be deterministic at the time of table creation, but can subsequently be recompiled and made non-deterministic without invalidating the virtual column. In such cases the following steps must be taken after the function is recompiled: a)Constraint on the virtual column must be disabled and re-enabled. b)Indexes on the virtual column must be rebuilt. c)Materialized views that access the virtual column must be fully refreshed. d)The result cache must be flushed if cached queries have accessed the virtual column. e)Table statistics must be regathered. 5)Virtual columns are not supported for index-organized, external, object, cluster, or temporary tables. 6)The expression used in the virtual column definition has the following restrictions: a.It cannot refer to another virtual column by name. b.It can only refer to columns defined in the same table. c.If it refers to a deterministic user-defined function, it cannot be used as a partitioning key column. e.The output of the expression must be a scalar value. It cannot return an Oracle supplied datatype, a user-defined type, or LOB or LONG RAW.

2018 - MySQL 8 - The next big thing!
 
59:03
https://media.ccc.de/v/froscon2018-2201-mysql_8_-_the_next_big_thing What's new? MySQL ist seit vielen Jahren eine der am meist verbreiteten Datenbanken überhaupt. Sie wird heute in vielfältigsten Anwendungen eingesetzt - von dem kleinen, privaten Internetauftritt bis zu unternehmenskritischen Einsätzen wie bei Booking.com oder auch zahlreichen DAX notierten Unternehmen in Deutschland. Im April 2018 hat Oracle sein neues Datenbankmanagementsystem MySQL 8.0 als Nachfolgeversion für die MySQL 5.7 freigegeben. MySQL 8 enthält zahlreiche Verbesserungen und zusätzliche Funktionen. Diese umfassen Erweiterungen im Bereich SQL (Windows Functions, Common Table Expressions), GIS (Spatial Reference Systems), Reliability (ACID DDL, Transactional Data Dictionary), Security (OpenSSL, SQL Roles, New Default Authentication), Invisible Indexes u.v.m. Die größte Neuerung betrifft die Unterstützung für NoSQL Datenbanken auf Basis des neuen MySQL X-Protocols. Ab Version 8 kann MySQL somit auch als dokumentenbasierte Datenbank genutzt zu werden und tritt in Konkurrenz zu Document Store Datenbanken. In diesem Vortrag werden wir einen Einstieg in MySQL 8 vermitteln und einige der über 500 neuen Funktionalitäten vertiefen. Der Vortrag enthält zahlreiche live Demos!
