-918: Stack overflow 

Explanation:

Nested calls of DB procedures, triggers or subqueries or very complicated VALUE EXPRESSION resulted in the maximum stack usage allowed for a task. Further nesting is not possible. The execution of the command was cancelled.

User Action:

  1. Further limit the nesting depth of the calls with suitable queries in the DB procedures and triggers.
  2. Try to limit the nesting depth by dividing the SQL statement into several substatements.
