If you want to remove a row from a table, you can use the DELETE statement with a WHERE clause to identify the row. The following sample script deletes one row:
<?php
$con = odbc_connect('FYI_SQL_SERVER','sa','FYIcenter');
$sql = "DELETE FROM fyi_links WHERE id = 1102";
$res = odbc_exec($con, $sql);
if (!$res) {
print("SQL statement failed with error:\n");
print(odbc_error($con).": ".odbc_errormsg($con)."\n");
} else {
$number_of_rows = odbc_num_rows($res);
print("$number_of_rows rows deleted.\n");
}
odbc_close($con);
?>
If you run this script, you will get something like this:
1 rows deleted.
If you run it again, no rows will be deleted. And you will get something like this:
0 rows deleted.
