SQL statement in MySQL

Hi there,

Anyone can guess what's wrong with this SQL statement in MySQL?

SQL = "SELECT TopicPKey,TopicNo,Description, [TopicNo] & ' - ' & [Description] AS TopicDescription FROM viewTopics WHERE fSubjectPKey=" & SubjectPKey & " ORDER BY TopicNo"

The same statement works for MSAccess but not MySQL, the TopicDescription returns as 0 in MySQL, where as something like "1.0 - Grammer" in MSAccess, which is correct.

Does the & char give problems in MySQL?  Maybe put Description in [] in the SELECT clause.
The SQL command you give returns both TopicNo and Description AND a field constructed from both (TopicDescription).  Why not do the construction when you require it rather than in the SQL.  (Less data retrieved from server)

It looks like the MySQL is attempting to subtract Description from TopicNo

I'm sorry, the sql statement list above give a error. NOT returning 0.

AndyAinscow, Why I'm doing this is because I wants to bind the data to a DataCombo to display TopicNo - Description.

If you're doing this in a script or with raw mySQL code, you should replace the 'concat()' keyword.
SELECT TopicPKey,TopicNo,Description, concat(TopicNo, ' - ' ,Description) AS TopicDescription
FROM ...
