Hi Premkumar,
An SQL widget in OutSystems MUST have an output parameter.
For SELECT SQL statements it must be a list that matches the returned columns.
For SQL statements that don't return data like UPDATE, DELETE, unfortunattly you need to set at least one output parameter. Just create a structure called SQL with a text attribute and add it as output parameter. That will fix the error. It is stupid the way it works, but although reported to OutSystems many times, it still works like this
