Hi,

Given 2 tables:

Table1:
id Auto,int,PrimKey
table2id int
txt nvarchar50

Table2:
id Auto,int,PrimKey
order int

The scenario: Table2.order defines how the table1.txt is should be ordered.
Table1.table2id contains the id of the order. This cannot be changed

How do I select all Table1.txt values but ordered by their corresponding
values of the table2.order field?

--
Thx,
PipHans

Hi

The following should do what you require:

SELECT T1.id, T1.txt
FROM Table1 T1 JOIN Table2 T2 ON T1.Table2Id = T2.id
ORDER BY T2.order

It complains about the from-clause being wrong.
If I add "LEFT JOIN" instead of "JOIN", it runs like it should. (thx btw

Can you explain why it didnt run with just "join"?

Hi

A LEFT JOIN would be all rows in the left hand side table (Table1) with any
matching rows in the right hand table (Table2) therefore an entry in Table2
does not have to exist. If an entry in Table2 does not exist then NULL
values are returned.

JOIN (or INNER JOIN) is where both tables have to contain the joined data.

As you didn't post the offending query or the actual error message, the only
thing I can imaging is some other syntax error:

SELECT T1.id, T1.txt
FROM Table1 T1 LEFT JOIN Table2 T2 ON T1.Table2Id = T2.id
ORDER BY T2.order

Should work OK.

John

Since what John suggested is legal syntax in SQL Server (save that
he should have put the last "order" in brackets), I suspect that
you are not using SQL Server, but some other DB engine.

True, I only tested on Access. - The SQL server cant be reached from home

Yep. It worked on the SQL server at work...I only tested it on access
yesterday.

While both Access and SQL Server both claim to run SQL, there are
significant differences between the two - as there is about between
any pair of DBMSs.
