-198 THE OPERAND OF THE PREPARE OR EXECUTE IMMEDIATE STATEMENT IS BLANK OR EMPTY

Explanation
  The operand (host variable or
string constant) that was the object of the PREPARE or EXECUTE IMMEDIATE
statement either contained all blanks or was an empty string. A DBRM
built in Version 2 Release 3 cannot be used on a Version 2 Release
2 system if the distributive functions were used. If this error appears
on Version 2 Release 2 and the DBRM was built on Version 2 Release
3, then the program needs to be precompiled again to correct the problem.

System action
  The statement cannot be processed.

Programmer response
  Correct the logic of the application program
to ensure that a valid SQL statement is provided in the operand of
the PREPARE or EXECUTE IMMEDIATE statement before that statement is
executed.
