hello all, after tried so much now posting here. i have two programs sql.php and form.jsp. i want to do insert values into mssql database from user input form. sql.php is able to insert the values into database. i have connected database using ODBC.form.jsp is able to give user input form where user can enter name.
when i submit the name it will successfully stored into the database. but if i submit the same name also it will get stored. i don't want store same name twice in the database.and it should notify the user that name already exist in the database. i can't change my database schema to unique constraint.
i need to accomplish throgh program. how to give this validation ?
$connect = odbc_connect('SerDB','sa', 'pwd'); echo "server connected"; $query=("INSERT INTO namemb(name) VALUES ('$_POST[name]')"); $result = odbc_exec($connect, $query);
