SQL in asp

I have problem with a sql query..

My query looks like this:

strSql = "SELECT Topic.name, Topic.topic_id, [Topic].[level],
Topic.content_t ype_id, Topic.visible, Topic.external_ link,
Topic.more_cont ent, Topic.content_l ink, Topic.list_link ,
Content_Type.ad min_file_name, content_Type.de scription ";
strSql += "FROM content_Type RIGHT JOIN Topic ON
content_Type.co ntent_type_id = Topic.content_t ype_id "
strSql += "ORDER BY Topic.hierarchy ;";
But what I want to do is join in a secound table called ''menu''.
The 2 fields I want to join in is ''menu.topic_id '' and ''menu.language _id''

How can I join them in the same FROM query like this: menu.topic_id =
Topic.topic_id
If I understand tis right, I have to use two joins in the same FROM
sentence?

You should always specify the database or language, since some Access
SQL statments won't work in MS-SQL Server and vice versa. And Oracle
always bites me on syntax. :)
strSql = "SELECT Topic.name, Topic.topic_id, [Topic].[level],
Topic.content_ type_id, Topic.visible, Topic.external_ link,
Topic.more_con tent, Topic.content_l ink, Topic.list_link ,
Content_Type.a dmin_file_name, content_Type.de scription ";
strSql += "FROM content_Type RIGHT JOIN Topic ON
content_Type.c ontent_type_id = Topic.content_t ype_id "
strSql += "ORDER BY Topic.hierarchy ;";

Unless I miss what you're doing, wouldn't an implicit JOIN and a WHERE
clause work on this? Something like:

SELECT Topic.name, Topic.topic_id,
[Topic].[level],Topic.content_ type_id, Topic.visible,
Topic.external_ link,Topic.more _content, Topic.content_l ink,
Topic.list_link ,Content_Type.a dmin_file_name,
content_Type.de scription,menu. topic_id,menu.l anguage_id
FROM Topic, content_Type, menu WHERE content_Type.co ntent_type_id =
Topic.content_t ype_id AND menu.topic_id =Topic.topic_id
ORDER BY Topic.hierarchy

Perhaps something like this is what you're looking for:

SELECT
Topic.name,
Topic.topic_id,
Topic.level,
Topic.content_t ype_id,
Topic.visible,
Topic.external_ link,
Topic.more_cont ent,
Topic.content_l ink,
Topic.list_link ,
Content_Type.ad min_file_name,
content_Type.de scription,
menu.language_i d
FROM
menu
INNER JOIN
(
content_Type
RIGHT JOIN
Topic
ON
content_Type.co ntent_type_id = Topic.content_t ype_id
)
ON
menu.topic_id = Topic.topic_id
ORDER BY Topic.hierarchy
Now, just trim it down into a string variable, and I *think* that's what
you're looking for (though it's hard to say for sure).

as an aside...
strSql += "ORDER BY Topic.hierarchy ;";


what sort of syntax is this? (+=)

I have not seen this before but it fails on my asp rig here. I suspect I
might be barking up the wrong tree here coz the ";" at the end of the line
suggests it is SQL syntax...

He's using JScript.

"+=" is javascript, among other things, and serves the same purpose as
"strSQL = strSQL & ". The semi-colon is also javascript, and is wholly
unnecessary when writing in that language except to separate statements on
the same line.

Also very useful helping you all to recognize the OP code was jscript.
