Query referring to the complex views can return SQL101N | |

Problem description: | |
Query can hit sql -101 error message. Setting the statement heap to automatic would not help much as query rewrite would keep doing join enumeration and exhaust statement heap by increasing the compile time . The issue is caused when there are aggregation above many level of complex views that contain large expressions, such as case statements and the result of those case expressions feed into two or more of the aggregations function. | |
