MS SQL Server Interview Question:

How To Execute a SQL Statement using odbc_exec()?

Submitted by: Administrator

Once you have created an ODBC connection object, you can use the odbc_exec() function to send a SQL statement to the SQL Server linked to the connection object for execution.

Here is a simple PHP script that creates a new schema and a new table:

<?php
$con = odbc_connect('ggl_SQL_SERVER','sa','GlobalGuideLine');

# creating a new schema
$sql = 'CREATE SCHEMA fyi';
odbc_exec($con, $sql);

# creating a new table
$sql = 'CREATE TABLE fyi.center (name VARCHAR(80))';
odbc_exec($con, $sql);

odbc_close($con);
?>

If you run this script for the first time, it will execute those two statements correctly for you. But if you run it again, you will some warning messages:

Warning: odbc_exec(): SQL error: [Microsoft]
[ODBC SQL Server Driver][SQL Server]
There is already an object named 'fyi' in the database.,
SQL state S0001 in SQLExecDirect in C: estggl_center.php
on line 6

Warning: odbc_exec(): SQL error: [Microsoft]
[ODBC SQL Server Driver][SQL Server]
There is already an object named 'center' in the database.,
SQL state S0001 in SQLExecDirect in C: estggl_center.php
on line 10

The messages are very clear and easy to understand.
