MS SQL Server Interview Question:

PHP ODBC - How To Create a New Table?

Submitted by: Administrator

If you want to create a table in the database connected through a ODBC DSN, you can run the CREATE TABLE SQL statement using the odbc_exec() function, as shown in the following sample script:

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

# creating a new table
$sql = "CREATE TABLE ggl_links ("
. " id INT NOT NULL"
. ", url VARCHAR(80) NOT NULL"
. ", notes VARCHAR(1024)"
. ", counts INT"
. ", time DATETIME"
. ")";
$res = odbc_exec($con, $sql);
if (!$res) {
print("Table creation failed with error: ");
print(odbc_error($con).": ".odbc_errormsg($con)." ");
} else {
print("Table ggl_links created. ");
}

odbc_close($con);
?>

If you run this script for the first time and there is no existing table called ggl_links in the database, you will get:

Table ggl_links created.

If you run it again, you will get:

Table creation failed with error:
S0001: [Microsoft][ODBC SQL Server Driver][SQL Server]
There is already an object named 'ggl_links' in the
database.
