JDBC Left join does not work the same as in access.

HXTT Access suports standard INNER JOIN, FULL JOIN, LEFT JOIN, RIGHT JOIN, NATURAL JOIN, CROSS JOIN, and self join. MS Access seems to support LEFT JOIN, INNER JOIN, , RIGHT JOIN, and sometimes MS Access' LEFT JOIN works like INNER JOIN.

SELECT [01_tills].name, [01_tills].tillnum, sum(media1) AS media1_total, sum(media2) AS media2_total, sum(media3) AS media3_total
FROM 01_tills LEFT JOIN 01_trans_line ON [01_tills].tillnum=[01_trans_line].till
GROUP BY [01_tills].name, [01_tills].tillnum
order by tillnum

This query only returns 2 records, and in access it returns 11 records? Why is this so?

Tried on simuliated data, and failed to find your issue. In our test, we thought that media1, media2, and media3 belong to 01_trans_line table. You can zip and email your test mdb file.

The tills table is linked to another access database. Does this matter? I will email you the database asap.
