Actually I did try that before and it also didn't work - because of another issue which I'm finding now - specifically that I can't seem to get column aliases to work.

So, this will work:

and shows this:

nuBuilder_1_4.jpg

But this won't work:

nuBuilder_1_5.jpg

Can you spot what I'm doing wrong?

Thanks,

When you press CTRL+SHIFT+I you can inspect the generated SQL statements.

Thanks, using this method it shows me that the generated SQL is:

Code: Select all

 SELECT lst_id,lst_subject,test,lst_notes
 FROM lesson_set ls LEFT JOIN term t ON t.ter_id = ls.lst_term
WHERE 1

Therefore I can see that the generated SQL is not using column aliases as I would expect - it is just trying to get a new column called "test" from result set.

It /should/ be:

Code: Select all

 SELECT lst_id,lst_subject,CONCAT(t.ter_year) AS 'test', lst_notes
 FROM lesson_set ls LEFT JOIN term t ON t.ter_id = ls.lst_term
WHERE 1

Am I missing something?

Thanks again.

It looks like the SQL parser cannot handle that. (You would need a SELECT * FROM (SELECT ...) construct again)

What's the purpose of this CONCAT anyway?

Code: Select all

CONCAT(t.ter_year) AS 'test'
