⟩ PHP ODBC - How To Delete Existing Rows in a Table?
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('ggl_SQL_SERVER','sa','GlobalGuideLine');
$sql = "DELETE FROM ggl_links WHERE id = 1102";
$res = odbc_exec($con, $sql);
if (!$res) {
print("SQL statement failed with error: ");
print(odbc_error($con).": ".odbc_errormsg($con)." ");
} else {
$number_of_rows = odbc_num_rows($res);
print("$number_of_rows rows deleted. ");
}
odbc_close($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.
