The technique Paul is describing involves adding another expression to each
of the SELECT clauses in the UNION. Up to now, you've probably just used
column names or functions in a SELECT clause, for example:

Just to be sure that this question is not supressed here :)
Recently I've come around that mysql (4.1.0 at least) treats different
queries containing non-english characters (in my case characters from
cp1251 charset) as the same query and therefore returns wrong results.

the instructions listed in a book i purchased called

Hi,
What can I do to find the cause / correct the following problem?
More often I get the following with Connector/J:
error com.mysql.jdbc.CommunicationsException: Communications link
failure due to underlying exception:
** BEGIN NESTED EXCEPTION **
java.io.EOFException
STACKTRACE:
I'd like to add an alternate solution. All these subselects and unions
seem overly complicated to me, when you could accomplish the same thing
with a single join. Also, union requires mysql 4.0.x or higher and
subselects require mysql 4.1 or higher. (Of course, you are obviously
using 4.1+

Hi,

From looking at this, you have a using temporary, on table b. Which may be
the biggest slow down, it's hard to somewhat tell. I assume you have

if I try a multi table update with a Berkley DB Table, where the updated

Although, you can try bdb(www.sleepycat.com), it comes with a java

Lets call the two serves A, and B. You set A as the master for B, and you set B as
