The exception we never knew we needed
If, by some great random cosmic chance, you are a reader of this blog, but not of Tom Kyte‘s, then you would have missed this post:
It appears to have been documented in the 9i documentation, complete with spelling error:
ORA-06548, 00000, "no more rows needed" Cause: The caller of a pipelined function does not need more rows to be produced by the pipelined function. Action: Catch the NO_DATA_NEEDED exception is an exception handling block.
Mind you, it’s not all that obvious since if the pipelined function does not handle the exception, nothing goes wrong – the exception is never raised by the calling SQL statement. It’s not obvious when ORA-06548 would ever be raised.
Looks like ORA-06548 can appear in the error stack.
