Chuzo,
SELECT MAX(LENGTH(...)) FROM ... ought to work.
SQL doesn't allow aggregate funcs like MAX() in the WHERE clause. Use
HAVING().
For nested queries like SELECT ... WHERE colvalue=(SELECT...) you need
version 4.1 or later.

I am a newbie here. I created a simple table defined as:
create table test (
testID int unsigned not null auto_increment,
testName varchar(128) not null,
primary key (testID)
) type = MyISAM;
Now, I filled out test table, and looking for the testName with max
characters.
The following caused the same error of:
ERROR 1064: You have an error in your SQL syntax. Check the manual
that corresponds to your MySQL server version for the right syntax to
use near 'select max(length(testName)) from test)' at line 1
select testName from test where length(testName) = (select
max(length(testName)) from test);
Then I copied a simple line from MySQL book:
select * from president where birth = (select min(birth) from president);
and adapted to my table with:
select * from test where testName = (select min(testName) from test);
and executed it with exactly the same error result.
MySQL version I am using is: 4.0.21-standard
Please help me why I get this error.
Thank you
Chuzo
