SQL query access pivot - error message 'field that has an invalid data type'

Question

I'm running an SQL Query on MS Access.

the query looks like this:

TRANSFORM MIN(X_VALUE*MULTIPLE & ' ' & Y_VALUE)
SELECT A.ID
FROM ((MY_TABLE_A A
       INNER JOIN MY_TABLE_B B ON B.ID = A.ID)
      INNER JOIN MY_TABLE_C C ON C.FOO1_ID = A.FOO1_ID)
LEFT JOIN MY_TABLE_D D ON A.FOO2_ID = D.FOO2_ID 

WHERE A.NUM ='FOO' AND A.FOO_ID<>0 AND FOO3=1

GROUP BY A.ID PIVOT X_NAME IN('BLAH1', 'BLAH2')

when running this against local MDB file, it works. when running this against Linked MDB (tables are linked to remote Oracle DB), I'm getting

ERROR [42000] [Microsoft][ODBC Microsoft Access Driver] The Microsoft Access database engine could not execute the SQL statement because it contains a field that has an invalid data type.

I've googled it, and couldn't find anything useful.

Any idea what can I do? thanks.

Answer 1

The only statement in the query that even vaguely seems it would cause data type issues is the mixed types in the transform statement. Perhaps the following would work:

TRANSFORM MIN(CSTR(X_VALUE*MULTIPLE) & ' ' & CSTR(Y_VALUE))
