Erste Fehler auf Löschvorgang mit Hilfe von SQL-Adapter

Question

ich SQL-Adapter verwenden und versuche Reihe von MySQL-Datenbank zu löschen, aber ich bin immer Fehler wie worklight.js:5355 Procedure invocation error. Runtime: No value specified for parameter 1. Performed query: delete from customer where id=?

// ******** *********** SQL Adapter *****************************

var procedurestat7 = WL.Server.createSQLStatement("delete from customer where id=?"); 
//preparedStatement.setLong(1, id); 
function procedure7(id) { 
    return WL.Server.invokeSQLStatement({ 
     preparedStatement : procedurestat7, 
     parameters : [id] 
    }); 
}

Answer 1

Sie sollen einen ID-Wert übergeben, aber in procedure7 setzen Sie es als: var id = "" und dann übergeben Sie das als id ... vielleicht ist das Ihr Problem?

function deleteData(id){ 
    console.log('Delete function called'); 
    var id = ""; 
    var custDelData = { 
      adapter:'SQL', 
      procedure:'procedure7', 
      parameter: [id] 
    } 


    WL.Client.invokeProcedure(custDelData,{ 
     onSuccess: DelSuccess, 
     onFailure: Delfailure 
    }); 
}
