Symptoms

Pro*C application intermittently fails with ORA-01400 when executing using 11g client client. The application is binding the data correctly but 10046 trace shows data is missing(NULL) and thus the error

ORA-01400: cannot insert NULL into ("ORA_TEST"."RTNS_CFQ"."SECT_ENABLE_MASK")

Error occurs only when using 11g client and doesn't occur with 10.2 client. Database version doesn't seem to matter.

IF 'Not Null' constraint is not enabled on the column then NULL data is silently inserted/updated leading to data corruption
