Table_A:  ID   APPL
         ------------
          B     BI
          A     BII
          *      *
          *      *
          C     BII
          *      *
          D     BI

Table_B:  Cnty  ID
         ------------
          US    C
          Aus   A
          Aus   B
          US    D

* signifies no data

why does the following produce an error: 1052??

SELECT DISTINCT APPL FROM Table_A, Table_B WHERE Table_A.ID=Table_B.ID AND 
Cnty="US" AND ID="*";
