Function to support Dynamic SQL

Hi,

     I was trying to create a function that accepts parameters, used to query a table. Those parameters are part of the query in the function.

Eg

create function (a varchar2,b varchar2)

return result number

LANGUAGE SQLSCRIPT  

SQL SECURITY INVOKER

as

(

exec 'select count(1) into result from table t1 where t1.col='||a||' and t2.col='||'b;

)

end;

But it says :-

As function was giving the error:- feature not supported: dynamic sql is not supported in the read only procedure/function

What could be the alternative for it?

If i need to create a procedure for the same. Below is the hurdle I'm facing again:-

Many of my functions have dynamic sql and multiple returns are there in the function.

So creating a procedure i would require a skip or GOTO statement. That also isn't provided in HANA.

Request you to help me with this.

Thanks,

Athrey
