Dear sir
I am faceing a problem in sql query.
I have two table.
1st table is maste table, In master table total 180 records are stored.
our requirement total 180 rows - 20 rows are stored in 2nd table, then display 160 mark as 'N' bcos stored in master table and other records are mark as 'Y' bcos its stored in 2nd table.
Table 1st
AppID FunCode SubFuncode FunName SubFunName Mark
Dis 1 30 &Maintain 0 N
Depos 2 30 &Maintain 0 N
Lox 3 30 &Maintain 0 N
LCredit 4 30 &Maintain 0 N
In 2nd table same records but only 20 records are stored.
AppID FunCode SubFuncode FunName SubFunName Mark
Dis 1 30 &Maintain 0 Y
Depos 2 30 &Maintain 0 Y
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))
Order BY aPPID,FunctionCode,sUBfUNCTIONcODE
From this query record is not show correctley.

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

 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?
