Data Query From MySQL Bracket In Fieldname Causing Havoc
Mar 12, 2009I am trying to write a query on an .aspx webpage connected to an .aspx.vb file to access some parts information on my mysql server. Everything works fine except for one poorly named file, which keeps breaking the query. The fields name (with the table name in front) is
invf12.PRICEE(1STU_M)
Those brackets seem to be the problem. I have tried putting single quotes around them, as in
invf12.' PRICEE(1STU_M)',
I can't do anything about the fieldname. The query in total looks like this:
Protected Sub LookupPart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LookupPart.Click
Dim strSQL As String = "SELECT invf12.ITEMCODE as Part, invf02.DESCRIPTION as Description, " + _

Query Designed For MySQL Translated To Work For SQL Server 2005?
Apr 10, 2010I've spent a whole day on this already without figuring it out. I'm hoping somebody can help me translate the following MySQL query to work for SQL Server 2005:

topics.id AS topicid, topics.*, users.*
FROM messages, topics, users WHERE messages.topic_id
= topics.id AND topics.user_id = users.id AND
topics.forum_id = " . $forumid . " GROUP BY
messages.topic_id ORDER BY maxdate DESC
$forumid is a QueryString value defined in the following VB.NET code-behind code:
forumName.Text = "<a href='ViewForum.aspx?forumid=" & row.id & "'>" & row.name & "</a>"
