    In query we try to fetch all Y marked row and N marked.
    SELECT TBLAPPLICATIONS.Name, TBLGROUPFUNCTIONS.AppID, TBLGROUPFUNCTIONS.FunctionCode, TBLALLFUNCTIONS.DefaultSubFunctionName,
    TBLGROUPFUNCTIONS.SubFunctionCode, 'Y' AS AssignedFunction
    FROM TBLGROUPFUNCTIONS INNER JOIN
    TBLALLFUNCTIONS ON TBLGROUPFUNCTIONS.AppID = TBLALLFUNCTIONS.AppID AND
    TBLGROUPFUNCTIONS.FunctionCode = TBLALLFUNCTIONS.FunctionCode AND
    TBLGROUPFUNCTIONS.SubFunctionCode = TBLALLFUNCTIONS.SubFunctionCode INNER JOIN
    TBLAPPLICATIONS ON TBLGROUPFUNCTIONS.AppID = TBLAPPLICATIONS.AppID
    WHERE TBLGROUPFUNCTIONS.GroupID = 12
    UNION ALL
    SELECT TBLAPPLICATIONS.Name, TBLALLFUNCTIONS.AppID, TBLALLFUNCTIONS.FunctionCode,
    TBLALLFUNCTIONS.DefaultSubFunctionName, TBLALLFUNCTIONS.SubFunctionCode, 'N' AS AssignedFunction
    FROM TBLALLFUNCTIONS INNER JOIN TBLAPPLICATIONS ON TBLALLFUNCTIONS.AppID = TBLAPPLICATIONS.AppID
    WHERE
    (TBLALLFUNCTIONS.AppID NOT IN (SELECT AppID FROM TBLGROUPFUNCTIONS WHERE GroupID = 12) OR
    TBLALLFUNCTIONS.FunctionCode NOT IN (SELECT FunctionCode FROM TBLGROUPFUNCTIONS WHERE GroupID = 12) OR
    TBLALLFUNCTIONS.SubFunctionCode NOT IN (SELECT SubFunctionCode FROM TBLGROUPFUNCTIONS WHERE GroupID = 12))

    try outer join

    SELECT TBLAPPLICATIONS.Name, TBLGROUPFUNCTIONS.AppID, TBLGROUPFUNCTIONS.FunctionCode, TBLALLFUNCTIONS.DefaultSubFunctionName,
    TBLGROUPFUNCTIONS.SubFunctionCode,
    DECODE (ISNULL(AssignedFunction),'Y','N') as AssignedFunction
    FROM TBLGROUPFUNCTIONS RIGHT OUTER JOIN
    TBLALLFUNCTIONS ON TBLGROUPFUNCTIONS.AppID = TBLALLFUNCTIONS.AppID AND
    TBLGROUPFUNCTIONS.FunctionCode = TBLALLFUNCTIONS.FunctionCode AND
    TBLGROUPFUNCTIONS.SubFunctionCode = TBLALLFUNCTIONS.SubFunctionCode INNER JOIN
    TBLAPPLICATIONS ON TBLGROUPFUNCTIONS.AppID = TBLAPPLICATIONS.AppID
    WHERE TBLGROUPFUNCTIONS.GroupID = 12

    Thumbs down This will not work.

    DECODE (ISNULL(AssignedFunction),'Y','N') as AssignedFunction
    1) DECODE() function is used incorrectly.
    2) ISNULL() is NOT an Oracle function.

    You are correct... again.
    mmhhh... isnull(), tables prefixed TBL*?... is poster working out a SQL Server query in an Oracle forum?
