Operations using BLOB and CLOB fields

Troubleshooting

Problem

When using BLOB fields in Framework Manager there are some limitations imposed upon their use by the underlying database. Due to the potential size of a BLOB field databases tend to prevent use of BLOBs in joins, grouping, scalar functions, and some aggregate functions.

Symptom

There are several scenarios where this issue may occur. Based on the different circumstances there are various error messages that may be encountered.
