I found the issue. It is throwing the error in SB-tables-data, and I checked the query. It is including the getclobval(). The query also throws the error in the editor. The problem is that I had the results sorted by the primary key. When I removed the sort by primary key in the data grid and in the test query in the editor they both run without issues.
So, the real problem was it choked on the sort. (17,591 rows). Does that make sense though?
Thanks
