Description:
On a simple query, running from C, I keep getting "Unknown column 'xxx' in field list" if the result is NULL.

If there is a result the query works.

4.x never did this.

I see lots of examples of the bug on the web, no fixes seem to work.

Please advise.

How to repeat:
SELECT COL1, COL2, COL3 FROM TABLE WHERE COL1 = 'X'

Thank you for a problem report. Please, send complete test case, with CREATE TABLE, INSERTs with some data, and a real code of your C application.

Sorry -- Please close this case -- my prg. was looping back on NULL result to rerun after rewriting the query (incorrectly)... NULL result works OK -- my requery method was writing incorrect SQL in some conditions -- problem resolved.  Thanks.

Closed as not a bug in MySQL code.
