Usage of Stored procedure in Calculation View

Hi Experts,

I have created a non read only procedure in HANA using SQL Console, But when i try to use that in my calculation view, I still get an error that it is read only procedure. I havent written "READS SQL DATA As" in my procedure, So it should be a read/write procedure. Could you please help me with any alternative?

Code :

create procedure "MYSCHEMA".PROCEDURE_TEST()

language sqlscript as


DECLARE tname varchar(50);


execute immediate ('select'||'*'||'from'||tname) ;


In calculation View :



Tried Both, But getting the error for both syntax as below :

"CALL for non read only procedure/function is not supported in the READ ONLY procedure/function"

    The error is saying that you cannot call a non read-only procedure (PROCEDURE_TEST) from a read-only procedure (Calc Views are by default read-only).

    This makes perfect logical sense - a read only procedure is obviously supposed to only read data, that's the basic definition. The idea is that the execution of a read-only procedure must not change any data in the system. Now if it had the capability to call a non read-only procedure, that makes the above definition entirely invalid. The very term "read-only" becomes meaningless.

    So basically, the system will only allow you to call a read-only procedure from another read-only procedure. Instead, please rewrite PROCEDURE_TEST to be a read-only procedure.

    Hi Jyotsna,
    You can achieve your requirement by creating HANA Table Function. Table function can be called from Calculation view by adding projection or aggregation nodes. You can 
    write SQL statements in the function. 
    Mainly, HANA stored procedures are used for DML (insert/ update/ delete)
