Accessing another password protected database in an SQL query in Access 97


I am currently working on an SQL query for Access 97. Given are the following tables (simplified for demonstration purposes), each of which are located in separate mdb files:

Table1 in C:\db\db1.mdb:

PartyId (PK)    Name
------------    --------    
1               A
2               B
3               C

Table2 in C:\db\db2.mdb:

PartyId (PK)    Date (PK)    Value
------------    ---------    -----
1               6/30/2014    4
1               7/1/2014     8
2               5/3/2014     3  
3               5/5/2014     5
3               5/3/2014     1
3               5/2/2014     2

Here I would like to look for the most recent value of each party, based on a defined date. So let's say, I'd label 7/5/2014 as the target date, then my query should return the following:

PartyId    Name    Date        Value
-------    ----    --------    -----
1          A       7/1/2014    8
2          B       5/3/2014    3
3          C       5/5/2014    5

I have created the following query in the C:\db\db1.mdb database:

SELECT T.TPartyId, Name, T.TDate, T.TValue
FROM Table1 INNER JOIN [
SELECT Table2.PartyId AS TPartyId, MAX(Table2.Date) AS TDate, FIRST(Value) AS TValue 
FROM Table2 IN 'C:\db\db2.mdb'
WHERE Table2.Date <= #7/5/2014#
GROUP BY Table2.PartyId]. AS T 
ON (Table1.PartyId = T.TPartyId);

The problem is that Table2 is actually located in a password protected database file. Therefore, I have tried to modify the query, as described in http://support.microsoft.com/kb/113701 , to the following:

SELECT T.TPartyId, Name, T.TDate, T.TValue
FROM Table1 INNER JOIN [
SELECT Table2.PartyId AS TPartyId, MAX(Table2.Date) AS TDate, FIRST(Value) AS TValue 
FROM [;database=C:\db\db2.mdb;PWD=mypwd].Table2
WHERE Table2.Date <= #7/5/2014#
GROUP BY Table2.PartyId]. AS T 
ON (Table1.PartyId = T.TPartyId);

However, this always results in a syntax error. I suspect that the follow up brackets found in the

INNER JOIN [ … [;database= … ] … ] 

statement are the cause of the failure. Unfortunately Access 97 always requires aliases to be enclosed in square brackets, followed by a period, whereas Access 2000 and higher don't have this limitation. Is there any way this query can be accomplished with Access 97 nonetheless? Thanks.


Solution

  • Finally, after countless trial & error sessions, I've found a solution. This line seems work and also avoids placing two opening square brackets after each other:

    FROM Table2 IN '' ';database=C:\db\db2.mdb;PWD=mypwd'
    

    It's a shame that this isn't documented somewhere in a proper manner.
