When Crystal Reports performs joins, it adds { oj sql }
; to the SQL statement, e.g.:
SELECT RightTable.*, LeftTable.*
{ oj(FROM RightTable INNER JOIN LeftTable ON RightTable.RHS = LeftTable.LHS) }
The Easysoft Oracle ODBC Driver did not ignore or strip this entry thus causing the error. This was fixed in Easysoft ODBC-Oracle Driver V1.3.
