Question

In order to not save a user that already exists in the stage, I am using the following IF NOT EXISTS statement in my query.

public function save() {
    // new record
    if ( $this->id == null ) {
        $query = "IF NOT EXISTS(SELECT * FROM Table_A WHERE user_id ='{$this->user_id}' and stage_id = '{$this->stage_id}') INSERT INTO Table_A(".
            'id, '.
            'user_id, '.
            'stage_id, '.
            'create_date '.
            ') OUTPUT inserted.id '.
            'VALUES ('.
                'newid(), '. 
                '%s, '.
                '%s, '.  
                'getdate()'.
        ')';

$rs = $this->db->Execute($query);

        if ( $rs->EOF ) {
            return false;
        }

        $rs->Close();
}

..It does the job, but when the user does exist it’s throwing this error:

PHP Fatal error: Uncaught exception ‘com_exception’ with message ‘Source: ADODB.Recordset
Description: Operation is not allowed when the object is closed.’

Wasn’t sure the best way to handle this was, any help is appreciated, thank you!

Because you close the Recordset by $rs->Close();, the next data fetch from the Recordset is not allowed. You could return $rs;, and after you get your data then close it.
