connection from the
button from the scenario dialog.
The dialog that appears contains the list of existing scenarios that
apply to SQL documents.
Set parameter values for SQL placeholders from the
Parameters button from the scenario dialog.
For example in SELECT * FROM `test`.`department` where DEPT = ? or
DEPTNAME = ? two parameters can be configured for the place holders
(?) in the transformation scenario.
When the SQL statement will be executed, the first placeholder will be
replaced with the value set for the first parameter in the scenario, the second

scenario dialog is not recommended. It is due to a limitation of the SQL
Server driver for Java applications. An example of stored procedure call
that is not recommended is: call dbo.Test(22,

or a CLOB one) cannot be displayed entirely in the result table.
Right click on the cell containing the complex value.
Select the action Copy cell from the popup
