CLOB: ORA-01461: can bind LONG value for insert into a LONG



The user wants to insert json documents into external tables (Oracle 12c) using Clob support in Pega 7.2.1. It works for small documents < 4K but fails with ORA-01461 when larger documents > 4K are saved.

Error Messages

** ORA-01461: can bind a LONG value only for insert into a LONG column"

Steps to Reproduce

Page-New Row
Property-Set Row
Call Save Row

Root Cause

Clob support was enhanced after 7.2.1 (in 7.2.2). The changes made to use the setClob() API with Clob columns for Oracle were back ported to 7.2.1.


Apply Hfix-30370

Any Pega 7.2.1 user can install this hfix but the fix will only benefit Oracle users inserting large values into Clob columns.
