I made it up so I could show an int data type in this table, and I was thinking of those websites where points are awarded for giving correct answers.Other than that, this My SQL database table is relatively normal, though it is greatly simplified.Execution continues with the next statement, even if there is a TRY/CATCH block or if SET XACT_ABORT is ON.Use the combination of a RAISERROR severity of 0 to 10 and the WITH NOWAIT clause for a statement that sends output to the Messages windows immediately, like this one: Don't be deceived if messages are obscured by the Results windows of SSMS or the Grids windows in Query Analyzer.The index can always be created once the update completes. Executing the update in smaller batches The query can be further optimized by executing it in smaller batches. The code below updates the records in batches of 20000. When updating in batches, even if the update fails or it needs to be stopped, only rows from the current batch are rolled back. Disabling Delete triggers Triggers with cursors can extremely slow down the performance of a delete query.Disabling After delete triggers will considerably increase the query performance. Replacing Update statement with a Bulk-Insert operation An update statement is a fully logged operation and thus it will certainly take considerable amount of time if millions of rows are to be updated.The index update and Sort operation together take 64% of the execution cost. Removing index on the column to be updated The same query takes 14-18 seconds when there isn’t any index on col1.

To do so, we just need to follow these steps: I've tried to document the following Java My SQL UPDATE example so you can see these steps. To keep it simple, but also show several different My SQL data types, I’ve created the following example database table: create table users ( id int unsigned auto_increment not null, first_name varchar(32) not null, last_name varchar(32) not null, date_created timestamp default now(), is_admin boolean, num_points int, primary key (id) ); data type in this table, and I was thinking of those websites where points are awarded for giving correct answers.) I’ve populated this database table in some related articles (Java My SQL INSERT using Statement, Java My SQL INSERT using Prepared Statement), so when I run this SQL SELECT query from the My SQL command prompt: ---- ------------ ----------- --------------------- ---------- ------------ | id | first_name | last_name | date_created | is_admin | num_points | ---- ------------ ----------- --------------------- ---------- ------------ | 2 | Fred | Flinstone | 2010-06-23 | 0 | 6000 | | 3 | Barney | Rubble | 2010-06-23 | 0 | 5000 | ---- ------------ ----------- --------------------- ---------- ------------ 2 rows in set (0.00 sec) I've tried to document the following Java/My SQL SELECT example so you can see these steps. The first thing we need for our SQL SELECT query example is a sample database table.Note that in this example my My SQL database username is "root", my password is blank, and the database is running on the same computer where this program is run, so the database host name is "localhost": import *; /** * A Java My SQL SELECT statement example.* Demonstrates the use of a SQL SELECT statement against a * My SQL database, called from a Java program.To keep it simple — but also show several different data types — I've created the following My SQL database table: create table users ( id int unsigned auto_increment not null, first_name varchar(32) not null, last_name varchar(32) not null, date_created timestamp default now(), is_admin boolean, num_points int, primary key (id) ); -- insert some sample records insert into users (first_name, last_name) values ('Fred', 'Flinstone'); insert into users (first_name, last_name) values ('Barney', 'Rubble'); A few of these fields are a little contrived, but I wanted to show several different data types in one table, so this is what I came up with.
