LIMIT keyword and SQL Server

[Migrated From Jforum.net]

Hi,

generic_queries.sql uses LIMIT keyword but SQL Server doesn't support it. So users get an exception (in my case, when a forum is moderated by a group and group name is clicked at the bottom of the forum page - UserModel.selectAllByGroup query).

So sqlsever.sql should include UserModel.selectAllByGroup, but I couldn't find an equivalent keyword in SQL Server. What can be done?

My temp solution was to copy UserModel.selectAllByGroup to sqlsever.sql and to change it as:

UserModel.selectAllByGroup = SELECT \
	user_email, u.user_id, user_posts, \
	user_regdate, username, deleted, \
	user_karma, user_from, \
	user_website, user_viewemail \
	FROM jforum_users u, jforum_user_groups ug \
	WHERE u.user_id = ug.user_id \
	AND ug.group_id = ? \
	AND (? <> ? OR 1=1) \
	ORDER BY u.user_id

Are you getting this error:
ERROR: LIMIT #,# syntax not supported.
Use separate LIMIT and OFFSET clauses.

I am seeing this with postgres and the recent 2.1.5 source.

Fixed LIMIT , OFFSET errors were fixed with a cvs update.

No, actually my error message was something like "LIMIT: Unknown keyword", I couldn't find the output file, so couldn't copy the exact error here. But the error (and SQL Server documentation) says that SQL Server doesn't support LIMIT keyword at all.

In my temp solution, I just removed it. It now works, but I don't know what's going to happen, when number of records are too much...

I guess your solution is for posgres. But thanks for the reply

Found the exact error, and it happens very frequently

I'm removing LIMIT from all queries, but this may have other side effects...
