Question

I’ve been able to make a query using MS Access 2010 that does just what I want but I am having trouble doing so in SQLite3. Here is the Access SQL

SELECT pubacc_lo.*
FROM pubacc_en 
LEFT JOIN pubacc_lo ON pubacc_en.call_sign = pubacc_lo.call_sign;

Basically it selects all of the columns in the pubacc_lo table and the rows where the call_sign fields are equal between the tables. This does not select any of the pubacc_en data into the final query in MS Access.

Playing around in SQLite 3, the closest I’ve gotten was

SELECT * FROM PUBACC_LO, PUBACC_EN WHERE PUBACC_en.call_sign=PUBACC_LO.call_sign

But this statement selects all of the data in the EN table along with the LO table (cross join?). I’ve tried some left outer joins but haven’t had any luck. Any tips would be appreciated!

Answer 1

You should be able to use the same query as you got from Access. SQLite3 does support left outer joins.

As for your query, if you only want the fields from the LO table, then ask for that in your SELECT clause like this:

SELECT PUBACC_LO.* 
FROM PUBACC_LO, PUBACC_EN 
WHERE PUBACC_en.call_sign=PUBACC_LO.call_sign 

but the problem here is that it will only return call_signs with entries in both tables, while the outer join from access will return all rows from PUBACC_EN irrespective of whether there is a corresponding PUBACC_LO entry..
