TO configure MY& SQL:

MySQL was successfully installed. Now we want to configure it. Leave the check box "Configure the MySQL Server Now" checked, and click "Next>". After you do that, you should see a window that looks like this:

12. 13. BASIC COMMANDS OF MYSQL 14. 1.CREATE Command The Create command is used to create a table by specifying the tablename, fieldnames and constraints as shown below: Syntax: $createSQL=("CREATE TABLE tblName"); Example: $createSQL=("CREATE TABLE tblstudent(fldstudid int(10) NOTNULL AUTO_INCREMENT PRIMARY KEY,fldstudName VARCHAR(250) NOTNULL,fldstudentmark int(4) DEFAULT '0' "); 15. Example: $createSQL=("CREATE TABLE tblstudent(fldstudid int(10) NOTNULL AUTO_INCREMENT PRIMARY KEY,fldstudName VARCHAR(250) NOTNULL,fldstudentmark int(4) DEFAULT '0' "); 16. 2.SELECT Command

The Select command is used to select the records from a table using its field names. To select all the fields in a table, '*' is used in the command. The result is assigned to a variable name as shown below:

Syntax:

$selectSQL=("SELECT field_names FROM tablename");

Example:

$selectSQL=("SELECT * FROM tblstudent");

17. 3.DELETE COMMAND

The Delete command is used to delete the records from a table using conditions as shown below:

Syntax:

$deleteSQL=("DELETE * FROM tablename WHERE condition");

Example:

$deleteSQL=("DELETE * FROM tblstudent WHERE fldstudid=2");

18. 4.INSERT Command

The Insert command is used to insert records into a table. The values are assigned to the field names as shown below:

Syntax:

$insertSQL=("INSERT INTO tblname(fieldname1,fieldname2..) VALUES(value1,value2,...) ");

Example:

$insertSQL=("INSERT INTO Tblstudent(fldstudName,fldstudmark)VALUES(Baskar,75) ");

19. 5. UPDATE Command

The Update command is used to update the field values using conditions. This is done using 'SET' and the fieldnames to assign new values to them.

Syntax:

$updateSQL=("UPDATE Tblname SET (fieldname1=value1,fieldname2=value2,...) WHERE fldstudid=IdNumber")

Example:

$updateSQL=("UPDATE Tblstudent SET (fldstudName=siva,fldstudmark=100) WHERE fldstudid=2");

20. 6.DROP Command

The Drop command is used to delete all the records in a table using the table name as shown below:

Syntax:

$dropSQL=("DROP tblName");

Example:

$dropSQL=("DROP tblstudent");

21. ADVANTAGES

very fast

reliable and easy to use

multi-threaded multi-user and robust SQLdatabase server.

22. DISADVANTAGES

Missing Sub-selects.

MySQL doesn't yet support the Oracle SQL extension: i SELECT ... INTO TABLE , but supports INSERT INTO ...SELECT ..

Does not support Stored Procedures and Triggers.

MySQL doesn't support views, but this is on the TODO.
