Input parameters filled at runtime in SAP HANA SQL?

Hi,

I got a graphical calculation view with a mandatory input parameter.

I want to write an SQL statement in a way that the value I pass to the input parameter isreadfrom another view  at runtime.

So instead of this:

select* from view1

with parameters

  'PLACEHOLDER' = ( '$$parameterA$$', 'Value');

I want to do this:

select* from view1

with parameters

  'PLACEHOLDER' = ( '$$parameterA$$', (select"columnB"from view2 where ....));

However, the system responds "sql syntax error: incorrect syntax near "(" "

Any ideas, or this this a restriction of HANA SQL?

Thanks in advance and best regards,

Christoph
