If Is Null in Select Statement

Greetings,
I am getting the following error
"Server: Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword 'IF'."
My SQL statement is:
SELECT dbo.tbl1.col1, dbo.tbl1.col2, dbo.tbl1.col3, dbo.tbl1.col4,
IF IS NULL(dbo.qry1.col5) THEN BEGIN dbo.qry2.col3 END ELSE BEGIN
dbo.qry1.col5 END
FROM dbo.tbl1 LEFT OUTER JOIN
dbo.qry2 ON dbo.tbl1.col4 = dbo.qr1.col3
LEFT OUTER JOIN
dbo.qry1 ON dbo.tbl1.col4 = dbo.qry1.col5
Note: qry1 and qry2 are the same query but am join different columns to the
same column in the table
Thanks for the help
KeithSELECT ..., COALESCE(qry1.col5, qry2.col3)
This is my signature. It is a general reminder.
Please post DDL, sample data and desired results.

OR COALESCE(Columntocheck[,ColumnTocheck], ElseValue). If you wanna put an
IF / CAse Expression in your query refer to the BOL and to the syntax of
CASE, example:
CASE Somecolumn
WHEN NULL THEN 'SomeValue'[Or a cloumn]
WHEN ...
...
ELSE 'Something'
END

SQL Statement. What you want is the SQL Case Expression. (look it up in
Books OnLIne)
as Folows:
SELECT dbo.tbl1.col1, dbo.tbl1.col2, dbo.tbl1.col3, dbo.tbl1.col4,
Case When dbo.qry1.col5 Is Null
Then dbo.qry2.col3
Else dbo.qry1.col5 End
FROM dbo.tbl1
LEFT OUTER JOIN dbo.qry2
ON dbo.tbl1.col4 = dbo.qr1.col3
LEFT OUTER JOIN dbo.qry1
ON dbo.tbl1.col4 = dbo.qry1.col5

The query can be re-written as
SELECT dbo.tbl1.col1, dbo.tbl1.col2, dbo.tbl1.col3, dbo.tbl1.col4,
ISNULL(dbo.qry1.col5, dbo.qry2.col3)
FROM dbo.tbl1 LEFT OUTER JOIN
dbo.qry2 ON dbo.tbl1.col4 = dbo.qr1.col3
LEFT OUTER JOIN
dbo.qry1 ON dbo.tbl1.col4 = dbo.qry1.col5
best Regards,
Chandra

If in current month

I need to do this but can't find the syntax:

IIf(Fields!EnteredDate.Value is in current month , Cint(Fields!PC.Value), CInt(0))

I think theres a month, day and date function that you can use for this.|||

Failing that something like:

IIF(DateAdd("m",0,Fields!EnteredDate.Value) = DateAdd("m",0,now()), Cint(Fields!PC.Value), CInt(0))

DateAdd(<level to extract>, <Point in time>, <set>)

I'm not sure about the current date function. Isn't there a Global parameter which gets the system current date!?

|||

=iif(Month(Fields!EnteredDate.Value) = Month(Today), CInt(Fields!PC.Value), CInt(0))

See also: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vblr7/html/vafctmonth.asp

Similar to the Month() function, there are also other functions available in the VB Runtime Library - such as Year(), Day(), etc.

-- Robert

|||How can I restrict dates that are in this month and year. For example if today is 2/20/2006, I do not want that EnteredDate included. 2/20/2005 is acceptable though...|||

solved my second question:

=IIF(Month(Fields!EnteredDate.Value) & Year(Fields!EnteredDate.Value) <> Month(Today) & Year(Today),Cint(Fields!PDC.Value),0)

If Exists Statement In Stored Procedure

Hello all!

Newbie question:

There appears to be something wrong with this syntax in SQL Server 2000:

CREATE PROCEDURE spAddNewUser

@.UserName varchar (50),
@.Password varchar (10),
@.NewUserID int = null OUTPUT

AS

IF EXISTS (SELECT * FROM Security WHERE UserName = @.UserName)

I can't get past the last "if exists" statement, without getting a syntax error when checking syntax. I get "ERROR: Incorrect Syntax near ')'.

I'm sure it's a very simple mistake...

Thanks in advance for any help :-)I think the IF statement is expecting some more code.

if i add the code

begin
print 'yes'
end

after your code then i don't get any parse errors.

What extra code do you want to put in, as your stored procedure does not do anything at the mo :confused:|||I don't know if the code you have shown is what you have, but if it is you are missing the brackets around the paramter list.

CREATE PROCEDURE spAddNewUser
(
@.UserName varchar (50),
@.Password varchar (10),
@.NewUserID int = null OUTPUT
)
AS

IF EXISTS (SELECT * FROM Security WHERE UserName = @.UserName)

Also don't forget to use BEGIN and END if you need to run a block of code when the IF statment is true.|||Try this way:

CREATE PROCEDURE spAddNewUser
@.UserName varchar (50),
@.Password varchar (10),
@.NewUserID int = null OUTPUT
AS
IF EXISTS (SELECT * FROM Security WHERE UserName = @.UserName)
select 'exists!'
ELSE
select 'not exists!'|||all of you are correct...I guess it was just waiting for more info (what happens AFTER the IF EXISTS statement).

I just went ahead and completed the code and it was fine.

<blush>

If Exists Schema Fails

Could someone explain why

IF SCHEMA_ID('TestSchema') is nul CREATE SCHEMA TestSchema

Fails with Incorrect syntax near the keyword 'SCHEMA'.

Where as running the following statements

CREATE SCHEMA TestSchema

and

IF SCHEMA_ID('TestSchema') is null SELECT 1

succeeds without a problem.

Thanks

_GJK

Ok. I found the solution from

http://groups.google.com/group/microsoft.public.sqlserver.newusers/browse_thread/thread/69a4e9c45d045120/77c693f5043fbddc?lnk=st&q=schema_id&rnum=1#77c693f5043fbddc

|||

Actually the real root of your problem is that CREATE SCHEMA must be the first statement in a batch. Using dynamic SQL (as suggested in the link above) is a workaround as the dynamic statement itself is considered a new batch.

If exists for temp table

What is the syntax to drop a temporary table if exists ? I want to drop a

Thanks.create table ##temptable (id int)

If / Else Stored Proc -- What Am I doing wrong?

Bellow is the stored procedure. I wanted to do an If / Else statement. I'm getting a syntax error that something is wrong around my Begin / Else statements. If anyone knows what is wrong I would greatly appriciate it.

Thanks in advance as always.

RB

<code>

Create Proc UpdateFundsAndTotals
AS
IF (Select FundsAndTotals.fundID, FundsAndTotals.TotalPledges, TotalPledges.fundID, TotalPledges.TotalPledges From FundsAndTotals, TotalPledges Where FundsAndTotals.fundID = TotalPledges.fundID AND FundsAndTotals.TotalPledges != TotalPledges.TotalPledges)
Begin
Update FundsAndTotals
Set FundsAndTotals.TotalPledges = TotalPledges.TotalPledges
END
ELSE (Select FundsAndTotals.fundID, FundsAndTotals.TotalPledges, TotalPledges.fundID, TotalPledges.TotalPledges From FundsAndTotals, TotalPledges Where FundsAndTotals.fundID = TotalPayments.fundID AND FundsAndTotals.TotalPayments != TotalPayments.TotalPayments)
Begin
Update FundsAndTotals
Set FundsAndTotals.TotalPayments = TotalPayments.TotalPayments
END
Else
END

</code>

what you have is pseudo code..the syntax is :

IF (Select somecolumnfrom sometablewhere condition2 <>select anothercolumnfrom anothertablewhere condition2)BeginUpdate sometable1set somecol= somevaluewhere theconditionEndelsebeginUpdate sometablesset somecol= somevaluewhere theconditionendNote that when you are checking for A <> B in the IF statement A and B should have only 1 values each..you cannot have a result set comparing to another result set.

|||

Are you sure you can do <code>if <condition> else <condition></code> ? I think you need an extra "if" block

|||

This isn't valid SQL:

Begin
Update FundsAndTotals
Set FundsAndTotals.TotalPledges = TotalPledges.TotalPledges
END

That's one issue. You seem to be trying to piggy-back onto the selects in the IF statement. They're separate statements; that doesn't work.

|||I don't 100% understand your IF/ELSE needs, but try something like this:
CREATE PROC UpdateFundsAndTotals
AS
IFEXISTS(SELECT NULLFROM FundsAndTotals INNER JOINTotalPledges ONFundsAndTotals.fundID = TotalPledges.fundID WHERE FundsAndTotals.TotalPledges != TotalPledges.TotalPledges)

BEGIN

UPDATE
FundsAndTotals
SET
FundsAndTotals.TotalPledges = TotalPledges.TotalPledges
FROM
FundsAndTotals
INNER JOIN
TotalPledges ONFundsAndTotals.fundID = TotalPledges.fundID
WHERE
FundsAndTotals.TotalPledges != TotalPledges.TotalPledges

END

ELSE

BEGIN

IFEXISTS(SELECT NULLFROM FundsAndTotals INNER JOINTotalPayments ONFundsAndTotals.fundID = TotalPayments.fundID WHERE FundsAndTotals.TotalPayments != TotalPayments.TotalPayments)

BEGIN

UPDATE
FundsAndTotals
SET
FundsAndTotals.TotalPayments = TotalPayments.TotalPayments
FROM
FundsAndTotals
INNER JOIN
TotalPayments ONFundsAndTotals.fundID = TotalPayments.fundID
WHERE
FundsAndTotals.TotalPayments != TotalPayments.TotalPayments

END

END

|||wow Terri you have tremendous patience..you go to exceptional levels to understand a user's requirements..I always admire you for that.. Good job.|||

Thanks a lot Terri just wanted to post that your suggestion did the trick.

Thanks again.

RB

|||I am glad that helped! It seems to me that you don't really need the IF(EXISTS) parts of that since the WHERE condition in the UPDATEstatement should take care of the filtering.
