Script variables

Script variables

Script variable types

Input variable / Output variable

1. Create input variable / output variable
   • In the called script(by Call Script) / In the executed script(with Trigger)
     Open the properties of the target script variables in the project explorer, check [Use as script input variable] or [Use as script output variable].
     Refer to "Project explorer" for details.
2. Usage (script variables other than XML type)
   • In the main script(Call Script operation)
     • Input variable
       Specify the value to assign to the target script variable in the properties of Call Script.
       
       
       
       
     • Output variable
       Get the value as component variable from Mapper.
       
       
   
   
   • Trigger
     Refer to the help of each trigger.
   
   
   • In the called script(with Call Script) / In the executed script (with Trigger)
     Use as normal script variables in the script.
3. Usage (XML script variable)
   Result data of each component can be passed directly by using XML type script variables as input/output variables.XML variable value can also be used in the script to set Mapper schema.
   
   
   • In the main script(Call Script)
     Connect Call Script with other component with data flow.
     
     Right-click and drag&drop from target component to Call Script, and select "main_data -> <script input variable name> from [Draw data flow] or [Draw process flow and data flow].
     
     
     
     Right-click and drag&drop from Call Script to target component, and select "<script output variable name> -> main_data" from [Draw data flow] or [Draw process flow and data flow].
     
     
     
     For an overview of the process, the result data received from the component is passed to the XML type script input variable of the called script, and the result data of the called script is passed to the component via XML type script output variable.
     
     
   
   
   • Trigger
     Refer to the help for each trigger.
   
   
   • In the called script(with Call Script) / In the executed script (with Trigger)
     Connect start component/end component with other component with data flow.
     
     Right-click and drag&drop from start component to target component, and select "<script output variable name> -> main_data" from [Draw data flow] or [Draw process flow and data flow].
     
     
     
     Right-click and drag&drop from target component to end component, and select "main_data -> <script input variable name> from [Draw data flow] or [Draw process flow and data flow].
     
     
     
     For an overview of the process, the result data received from the main script / the executed trigger is passed from the XML type script input variable to the component, and the result data of the component is passed back to the main script via XML type script output variable.
     
     

Specification limitation

• If a variable of type decimal or date/time type is assigned invalid value in its [Initial Value], script will not execute.


• Setting null to an input variable from outside the script in which the input variable is declared, a variable is set its default value.


• If an output variable of type integer or date/time type is assigned a null, the variable dereferences its default value when it is used outside the script.

Notes

• If [Initial Value] or [Value when test is executed] is undefined, it will dereference its default value.


• If a script variable which dereferences null is specified in an input property field, the script variable is evaluated.
