Functions on CLOBS in SQRs running in Oracle 12.2 return null
We are finding that after several executions of the same function on a CLOB in an Oracle table, that we are getting a NULL value returned.
This is happening in our Oracle 12.2 database and NOT in our Oracle 12.2 database.
It is happening only in SQR and is not replicable in Oracle SQL.
Has anyone else encountered this issue?
