Hi everyone,

I have a stored procedure in mysql that returns lastnames based on a given parameter.
I am trying to call this procedure for a suggest control.
So, inside sql editor i have the following :
CALL fetch_lastnames_from_cost_centers(@@filter)

The suggest control seems to work but no results are returned.

I have also tried this :
SET @param = @@filter
CALL fetch_lastnames_from_cost_centers(@param)

But no results are returned either.

How can i call the mysql stored procedure inside sql editor ??
ProcessMaker only supports "SELECT" statements. You can get around this restriction by editing the source code.

Let's say that you have the following Dynaform:
(1.9 KiB) Downloaded 23 times
Which has a suggest field with the ID and variable named "selectTask" and the SQL:
SELECT TAS_UID, TAS_TITLE FROM TASK WHERE [email protected]@selectProcess

Then, edit the file workflow/engine/src/ProcessMaker/BusinessModel/Variable.php and change the executeSqlSuggest() function defined on line 673 from:
Code: Select all
    public function executeSqlSuggest($processUid, $variableName, array $arrayVariable = array())
        try {
            return $this->executeSqlControl($processUid, $arrayVariable);
        } catch (\Exception $e) {
            throw $e;
Code: Select all
    public function executeSqlSuggest($processUid, $variableName, array $arrayVariable = array())
       * In $arrayVariable: 
       * [      
       *    app_uid:   null,
       *    del_index: 0,
       *    dyn_uid:   "3475266175b3d69c951f2a3034351254",
       *    field_id:  "selectTask",
       *    filter:    "sur",                                 //what entered by the user
       *    limit:     20,
       *    order_by:  "ASC",
       *    selectProcess: "26792814759f981ea9c1fc5090238278" //variable in SQL query
       * ]  
      if ($variableName == 'selectTask') {
         //set to the ID of the DB connection or 'workflow' if a PM Table:
         $dbConnectionId = 'workflow';  //'1234567890abcdef1234567890abcedf';
         //change to match the name of the variable in the SQL statement:
         //use addslashes() instead of mysql_real_escape_string() if not a MySQL database: 
         $id = mysql_real_escape_string($arrayVariable['selectProcess']);
         //change to your SQL statement: 
         $oDB = new \Propel();
         $con = $oDB->getConnection($dbConnectionId);
         $rs = $con->executeQuery($sql);
         while ($rs->next()) {
            $aRow = $rs->getRow();
            //change to the name of the second field returned by the SQL:
            if (stripos($aRow['TAS_TITLE'], $arrayVariable['filter']) !== false) {
               $o = new \StdClass();
               //change to the name of the fields in your SQL statement:
               $o->value = $aRow['TAS_UID']; 
               $o->text  = $aRow['TAS_TITLE'];
               $aResult[] = $o;
         return $aResult; 
        try {
            return $this->executeSqlControl($processUid, $arrayVariable);
        } catch (\Exception $e) {
            throw $e;
This code should work for the suggest box in the DynaForm I gave you. Change the code to match the variable name, database connection ID, and SQL query for your suggest box.
