Hi MySQL-Users
I have a simple select statement like 'select id from table'. The result
is
0, becaues the id field is 0
You could use the IF() function and key off of the id value like this:
SELECT if(id=0, null, id) as id, if(id=0,null, field2) as field2, if(id=0,
null, field3) as field3
FROM tablename
However, if you don't want any rows with 0 as an ID, you take care of that
in the WHERE clause
SELECT id
