Selection problem

[Revelation]

Hi,

 

I've got this (simplified) table:

 

Name	Value
Ben	1

Ben	2
Tom	3

Hank4

 

What I would like to do is select every name from this table that has not got 2. The problem is that I can't use a subquery (MySQL 4.0) and that WHERE NOT Value = '2' doensn't work, because then Ben gets selected anyway (via Ben 1) and that's not what I want.

 

Can someone help me?

 

Thanks!

SELECT name, COUNT(*) as ct

FROM table

GROUP BY name

HAVING ct = 1

 

Interpreting your question as eliminating any name that has a value of 2, rather than a count of 2, use a temporary table instead of a subquery

 

CREATE TEMPORARY TABLE tmp SELECT name FROM tablename WHERE value = 2

 

Then

 

SELECT t.name

FROM tablename t

LEFT JOIN tmp p ON t.name = p.name

WHERE p.name IS NULL;

Thanks!

 

A pity there isn't another way than to create a temporary table

There is, but not until 4.1.
