Webinar: All About the Function Result Cache
 
01:08:47
Presented by Steven Feuerstein, Oracle Corporation The function result cache, added in Oracle Database 11g, offers developers a way to dramatically reduce the amount of time it takes to retrieve data requested repeatedly by database sessions (specifically, when the same rows of a table are fetched much more frequently than they are changed). This cache is stored in the SGA, shared across all sessions in the instance, and automatically purged of "dirty data" by the Oracle Database. Every application running on 11.1 or higher should be taking advantage of this feature. Best of all, there is minimal impact on your code to start using this feature.

What happens when a query is issued to SQL Server 2. How to check what is in SQL Server plan cache 3. Things to consider to promote query plan reusability What happens when a query is issued to SQL Server In SQl Server, every query requires a query plan before it is executed. When you run a query the first time, the query gets compiled and a query plan is generated. This query plan is then saved in sql server query plan cache. Next time when we run the same query, the cached query plan is reused. This means sql server does not have to create the plan again for that same query. So reusing a query plan can increase the performance. How long the query plan stays in the plan cache depends on how often the plan is reused besides other factors. The more often the plan is reused the longer it stays in the plan cache. How to check what is in SQL Server plan cache SELECT cp.usecounts, cp.cacheobjtype, cp.objtype, st.text, qp.query_plan FROM sys.dm_exec_cached_plans AS cp CROSS APPLY sys.dm_exec_sql_text(plan_handle) AS st CROSS APPLY sys.dm_exec_query_plan(plan_handle) AS qp ORDER BY cp.usecounts DESC As you can see we have sorted the result set by usecounts column in descending order, so we can see the most frequently reused query plans on the top. usecounts - Number of times the plan is reused objtype - Specifies the type of object text - Text of the SQL query query_plan - Query execution plan in XML format To remove all elements from the plan cache use the following command DBCC FREEPROCCACHE In older versions of SQL Server up to SQL Server 6.5 only stored procedure plans are cached. The query plans for Adhoc sql statements or dynamic sql statements are not cached, so they get compiled every time. With SQL Server 7, and later versions the query plans for Adhoc sql statements and dynamic sql statements are also cached. Things to consider to promote query plan reusability For example, when we execute the following query the first time. The query is compiled, a plan is created and put in the cache. Select * From Employees Where FirstName = 'Mark' When we execute the same query again, it looks up the plan cache, and if a plan is available, it reuses the existing plan instead of creating the plan again which can improve the performance of the query. However, one important thing to keep in mind is that, the cache lookup is by a hash value computed from the query text. If the query text changes even slightly, sql server will not be able to reuse the existing plan. For example, even if you include an extra space somewhere in the query or you change the case, the query text hash will not match, and sql server will not be able find the plan in cache and ends up compiling the query again and creating a new plan. Another example : If you want the same query to find an employee whose FirstName is Steve instead of Mark. You would issue the following query Select * From Employees Where FirstName = 'Steve' Even in this case, since the query text has changed the hash will not match, and sql server will not be able find the plan in cache and ends up compiling the query again and creating a new plan. This is why, it is very important to use parameterised queries for sql server to be able to reuse cached query plans. With parameterised queries, sql server will not treat parameter values as part of the query text. So when you change the parameters values, sql server can still reuse the cached query plan. The following query uses parameters. So even if you change parameter values, the same query plan is reused. Declare @FirstName nvarchar(50) Set @FirstName = 'Steve' Execute sp_executesql N'Select * from Employees where [email protected]', N'@FN nvarchar(50)', @FirstName One important thing to keep in mind is that, when you have dynamic sql in a stored procedure, the query plan for the stored procedure does not include the dynamic SQL. The block of dynamic SQL has a query plan of its own. Summary: Never ever concatenate user input values with strings to build dynamic sql statements. Always use parameterised queries which not only promotes cached query plans reuse but also prevent sql injection attacks.

How to Cache Database Queries with Redis in Laravel - Redis Series Episode 4
 
09:22
In this short episode, I show you how you can cache database queries for a certain period of time. This is really nice when you have data you know won't change during x period of time, because once it's in cache, Laravel knows to automatically skip the database query and immediately deliver the requested content from RAM. Super fast, super easy. Here's the complete project throughout all episodes: https://gitlab.com/Christf24/RedisCast/tree/master/ Next episode will go over tagging with Redis (for blog posts, movie genres, or whatever else).

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.

Webinar: Ten (Other) Top Tips for Improving PL/SQL Performance
 
01:08:03
Bulk processing (FORALL and BULK COLLECT), along with the function result cache, are the "big ticket" items when it comes to performance optimization with PL/SQL. But there's still more we can do to tweak our code for even better response times for our users. This third webast in the series starts with the automatic compiler optimization, showcases the extraordinary speediness of PGA data manipulation (a.k.a., package variables), and demonstrates the effect of the simple NOCOPY hint. We finish up with an introduction to pipelined table functions and some thoughts on optimizing your algorithms.
