If you care about SQL Server performance you need to take SQL Server Statistics into account.Statistics are lightweight and small objects which describe how data in SQL Server tables are distributed.You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected.The basic syntax of the UPDATE query with a WHERE clause is as follows − ---- ---------- ----- ----------- ---------- | ID | NAME | AGE | ADDRESS | SALARY | ---- ---------- ----- ----------- ---------- | 1 | Ramesh | 32 | Ahmedabad | 2000.00 | | 2 | Khilan | 25 | Delhi | 1500.00 | | 3 | kaushik | 23 | Kota | 2000.00 | | 4 | Chaitali | 25 | Mumbai | 6500.00 | | 5 | Hardik | 27 | Bhopal | 8500.00 | | 6 | Komal | 22 | MP | 4500.00 | | 7 | Muffy | 24 | Indore | 10000.00 | ---- ---------- ----- ----------- ---------- ---- ---------- ----- ----------- ---------- | ID | NAME | AGE | ADDRESS | SALARY | ---- ---------- ----- ----------- ---------- | 1 | Ramesh | 32 | Ahmedabad | 2000.00 | | 2 | Khilan | 25 | Delhi | 1500.00 | | 3 | kaushik | 23 | Kota | 2000.00 | | 4 | Chaitali | 25 | Mumbai | 6500.00 | | 5 | Hardik | 27 | Bhopal | 8500.00 | | 6 | Komal | 22 | Pune | 4500.00 | | 7 | Muffy | 24 | Indore | 10000.00 | ---- ---------- ----- ----------- ---------- If you want to modify all the ADDRESS and the SALARY column values in the CUSTOMERS table, you do not need to use the WHERE clause as the UPDATE query would be enough as shown in the following code block.PDF (US Ltr) - 39.4Mb PDF (A4) - 39.4Mb PDF (RPM) - 38.5Mb HTML Download (TGZ) - 10.9Mb HTML Download (Zip) - 11.0Mb HTML Download (RPM) - 9.6Mb Man Pages (TGZ) - 217.7Kb Man Pages (Zip) - 327.3Kb Info (Gzip) - 3.6Mb Info (Zip) - 3.6Mb My SQL Backup and Recovery My SQL Globalization My SQL Information Schema My SQL Installation Guide My SQL and Linux/Unix My SQL and OS X My SQL Partitioning My SQL Performance Schema My SQL Replication Using the My SQL Yum Repository My SQL Restrictions and Limitations Security in My SQL My SQL and Solaris Building My SQL from Source Starting and Stopping My SQL My SQL Tutorial My SQL and Windows My SQL NDB Cluster 7.5 My SQL Secure Deployment Guide option as part of a table reference.This option takes a list of one or more partitions or subpartitions (or both).All you need to do is to find the middle ground between the time it takes to recompile queries and improving query plans.

The implicit default value is tables for which there are foreign key constraints, the My SQL optimizer might process tables in an order that differs from that of their parent/child relationship. To do it click “Schedule maintenance” and specify the date of the first start and the interval with which the operation will be repeated.Besides all this, you can turn “on” the e-mail notification and receive letters if the maintenance job is “success” or “fail”.The columns that are not on the list retain their original values.I have the folowing: SQL: create or replace type my_object_type is object (id number, some_column varchar2); create type my object_table_type is table of my_object_type; PLSQL: create or replace package body my_package is l_tab my_object_table_type; procedure main is begin select cast ( multiset( select my_object_type ( id , some_column ) from ( select x , y from some_table ) ) as my_object_table_type ) into l_tab from dual; /* so far so good. but know i would like to be able to update specific records in l_tab ....
