How to execute dynamic select into query in hana procedure

Hi,

   I have to execute a select query result into a variable, so the script is :

      go_table_name := upper(R.company_schema) || 'GENERIC_OBJECT_T' ;

      qry := 'select count(1) into "goparent_constraint_company" from ' || go_table_name ||  ' where parent_row_id not in (select row_id from ' ||                go_table_name || ')';   

     EXECUTE IMMEDIATE(:qry);

  But on calling the procedure , i get an error : [337] (range 3) INTO clause not allowed for this SELECT statement exception: INTO clause not allowed for this SELECT statement

  What is the correct way to write this query?

Thanks,
