- Downloaded Mysql for Win 7 - mysql-5.5.12-winx64 (Link)
- Downloaded Toad for MySql
- Installed MySql and Toad
- All set for some exploration with Mysql
- Creating Databases
- Writing Procedures
- Checking Execution Plan
Welcome to world of MySql. Everytime when I try things like this, I recollect my inspiration from Bala.
Connect Using MySql Command Line Client
--Create a Database
CREATE DATABASE TestDB;
--Show Databases
SHOW DATABASES;
--USED Previous Example Post and Create those tables in MySQL
CREATE TABLE TestTable1
(
Number INTEGER AUTO_INCREMENT,
A VARCHAR(20) NOT NULL,
B VARCHAR(20) NOT NULL,
C VARCHAR(20) NOT NULL,
D VARCHAR(20) NOT NULL,
PRIMARY KEY (NUMBER)
);
(
Number INTEGER AUTO_INCREMENT,
A VARCHAR(20) NOT NULL,
B VARCHAR(20) NOT NULL,
C VARCHAR(20) NOT NULL,
D VARCHAR(20) NOT NULL,
PRIMARY KEY (NUMBER)
);
--SEE TABLE Created Details
DESCRIBE TestTable1;
--Entering Data in Tables Using Stored Procedure
DELIMITER $$
CREATE PROCEDURE dowhile()
BEGIN
DECLARE I INT DEFAULT 5;
v1loop: WHILE I < 10000 DO
INSERT INTO TestTable1(A,B,C,D)
SELECT CONCAT(I,'A'), CONCAT(I,'B'), CONCAT(I,'C'), CONCAT(I,'D');
SET I = I + 1;
END WHILE v1loop;
END$$
DELIMITER ;
--Execute MySQL Stored Procedure
call dowhile();
--Create Index
CREATE INDEX ABCD ON TestTable1 (A,B,C,D);
--Check Index on table
SHOW INDEX FROM testdb.TestTable1;
--SELECT Statement Example
SELECT Number FROM TestTable1 WHERE A = '1000A' AND B = '1000B' AND C = '1000C';
--Viewing Query Plan in MySql
Explain SELECT Number FROM TestTable1 WHERE A = '1000A' AND B = '1000B' AND C = '1000C';
Conceptually all TSQL best practices of MSSQL should be applicable for MySql as well. I hope so. I could not connect MySql client using Toad. I did this exercise using MySQL 5.5 Command Line Client.
This was a Good Learning!!
Thanks to Stackoverflow for helping me fix stored procedure error.
