Question

I have the strangest problem – when i run:

SELECT * FROM `words` WHERE `translation` = ''

i get: Showing rows 0 - 29 (6,925 total, Query took 0.0008 sec)

but when I run:

UPDATE `words` SET `translation`= NULL WHERE `translation`= ''

I get: 0 row(s) affected. ( Query took 0.2200 sec )

why doesn’t it want to udpate the rows? It is the same WHERE clause.

Answer 1

Ok, try this:

UPDATE words SET translation='$$$' WHERE translation = '';
UPDATE words SET translation=NULL WHERE translation = '$$$';

and secondly; maybe the column definition is not allowing NULL values? check the table design.
