Script With If Condition For Multiple Input Parameter That Can Be NULL
Jan 23, 2008I want to write an Query for a report that has 7 parameters. I want to allow Null for these parameters but at the same time in the Query i want to put an AND condition for all the parameters. I cannot put an OR condition.
For Example;
If i have a report with 2 parameters then the script will have 2* 2 If conditions
something like:-
if( @parameter1 is not Null and @parameter is not Null)
select A, B, C
From Table 1
Where parameter1 = @parameter1 and parameter2 = @prameter2
if( @parameter1 is not Null AND @parameter2 is Null)
select A, B, C
From Table 1
Where parameter1 = @parameter1
If( @parameter1 is Null AND @parameter2 is Not Null)
select A, B, C
From Table 1
Where parameter2 = @parameter2
If( @parameter1 is Null AND @parameter2 is Null)
select A, B, C
From Table 1
For 7 parameter there will be way too many If conditions. Is there an better approch to write a Query for such a situation?
Can I Print The Results Of A Condition Based On The Condition?
Feb 9, 2006For example..
select * from mytable where MyNum = 7
If this brings back more than 1 row, I want to display a message that says,
Print 'There is more than one row returned'
Else (If only 1 row returned), I don't want to print anything.
Can I do this? Thx!
COndition Spli - Error Date Condition
Apr 19, 2007Dear friends,
I'm having a problem... maybe it's very simple, but with soo many work, right now I can't think well...
I need to filter rows in a dataflow...
I created a condition spli to that... maybe there is a better solution...
And the condition is: Datex != NULL(DT_DATE)
(Some DATE != NULL)
[Eliminar Datex NULL [17090]] Error: The expression "Datex != NULL(DT_DATE)" on "output "Case 1" (17123)" evaluated to NULL, but the "component "Eliminar Datex NULL" (17090)" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error.
What is wrong??
Regards,
Pedro
Reporting Services :: SSRS IIF One Condition Or IIF Another Condition
Jun 22, 2015I am trying to write an visibility function to have message shown based on two different IIF conditions:
If behavior is to Add a customer ( if message =NAME ALREADY EXISTS, return " NAME ALREADY EXISTS", otherwize return " NAME CREATED")If behavior is to Delete a customer (( if message =NAME DOES NOT EXIST, return "NAME DOES NOT EXIST", otherwize return "NAME SUCCESSFULLY DELETED")
I tried the following which doesn't work:
=IIF((UCase(First(Fields!Message.Value, "DataSetName")) = "NAME ALREADY EXISTS"), "WARNING: NAME ALREADY EXIST", "NAME CREATED"),
IIF((UCase(First(Fields!Message.Value, "DataSetName")) = " NAME DOES NOT EXIST"), "WARNING: NAME DOES NOT EXIST", " NAME DELETED")

Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True
Sep 20, 2006Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on
An Easy Way To Reference The Nth Row From A Table Meeting A Condition X, And The Mth Row From The Same Table Meeting Condition Y
May 10, 2006Hi
I am developing a scientific application (demographic forecasting) and have a situation where I need to update a variety of rows, say the ith, jth and kth row that meets a particular condition, say, x.
I also need to adjust rows, say mth and nth that meet condition , say y.
My current solution is laborious and has to be coded for each condition and has been set up below (If you select this entire piece of code it will create 2 databases, each with a table initialised to change the 2nd,4th,8th and 16th rows, with the first database ignoring the condition and with the second applying the change only to rows with 'type1=1' as the condition.)
This is an adequate solution, but if I want to change the second row meeting a second condition, say 'type1=2', I would need to have another WITH...SELECT...INNER JOIN...UPDATE and I'm sure this would be inefficient.
Would there possibly be a way to introduce a rank by type into the table, something like this added column which increments for each type:
ID
Int1
Type1
Ideal Rank by Type
1

The solution would then be a simple update based on an innerjoin reflecting the condition and rank by type...
I hope this posting is clear, albeit long.
Thanks in advance

Subscription Issue With Null Default Parameter - Key Cannot Be Null
May 3, 2007I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
Key cannot be null. Parameter name: key
Returned SQLParam.SqlValue Is {Null} But Can't Test For Null?
Nov 5, 2007I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output.
When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok.
When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out.
I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null)....
{
// I'm here!! I thought the watch says this is null???
}
Sorry if this is obvious, but I can't work this one out!!

WITH RETURNS NULL ON NULL INPUT Not Working?
May 3, 2006Hello.
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3))
RETURNS nvarchar(1000)
WITH RETURNS NULL ON NULL INPUT
AS
EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
And it works as expected, except when I use NULL:
DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?
Transact SQL :: Database Null Value And String Null
Oct 27, 2015We have a case where in we should show date based on conditions for e.g if we had a column defined as
col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition
Normaly date values are stored here e.g under col 20150901 .
Case
when col>'20150901' then 'NULL'
else col
end as Derivedcol
Note this is an extract process and we are presenting data by pumping the data in a table .
Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?

Null Result Returned Even Though IS NOT NULL Specified.
Apr 25, 2007Hi guys,
I've got a query on a particular table returning an odd result:
SELECT DISTINCT WorkStation
FROM Invoice
WHERE WorkStation Is Not Null
ORDER BY WorkStation
This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.
SELECT DISTINCT AccountNumber
FROM Suppliers
WHERE AccountNumber Is Not Null
ORDER BY AccountNumber
I can't reproduce these results on another site on a table of the same structure, or on another table at this site.
Any suggestions as to what might be going on?

Value Is Null Remotely - Non Null Locally
Aug 15, 2006ok here is a WIERD issue.
I've NEVER EVER had this issue, I have always done this and it works great both locally and remotely.
I have a table, which is a "customers" table.
I have a stored procedure which takes in parameters (name, address, password etc...) and returns me back, via a parameter declared as output - the customer ID.
I've always done this, and works great.
Now, this works fine locally.
IF I try to run this/do the exact same execution of commands (create a customer) remotely (where the database is stored, so copying everything from local to "over there") it does not work.
I get a DBNULL value back from the parameter, declared as an int output.
IF I copy and paste this Stored procedure Query/command into Query Analyzer and execute it (on the remote connection) and run it, giving it the exact same values as I do, it works perfect and returns me the correct value.
I've even dropped and recreated the stored procedure but makes no difference.
Any ideas why?
here is the proc....
CREATE PROCEDURE [dbo].[DoCreateNewCustomer] (
@theFirstName nvarchar(25),
@theLastName nvarchar(25),
@theAddress nvarchar(50),
@theCity nvarchar(15),
@thePostCode nvarchar(9),
@thePhoneNumber nvarchar(21),
@theMobilePhoneNumber nvarchar(21),
@theIPAddress nvarchar(25),
@thePassword nvarchar(50),
@theEmailAddress nvarchar(30),
@result int output
)
AS
SET @result = (SELECT [ID] FROM Customers WHERE emailAddress = @theEmailAddress)
IF @result IS NOT NULL
SET @result = -1
ELSE
BEGIN
SET @result = @@IDENTITY
INSERT INTO Customers (
Firstname,
Lastname,
Address,
City,
Postcode,
PhoneNumber,
MobileNumber,
IPAddress,

EmailAddress
)

@theFirstName,
@theLastName,
@theAddress,
@theCity,
@thePostCode,
@thePhoneNumber,
@theMobilePhoneNumber,
@theIPAddress,
@thePassword,
@theEmailAddress
)
END
GO
Any ideas why it does not work when calling the stored proc from either a web app, or through QA remotely but works fine when I run that command in QA or locally?
Again, if I do:
EXEC DoCreateNewCustomer { params } - the output result it gives me is DBNULL (if on remote connection)
If I do this locally, perfect
If I copy and paste pretty much the SP into QA and execute it on the remote connection, works great, and also locally.
Change The Column From NULL To NOT NULL
Feb 29, 2008Hi all,
One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.
I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.
Is there any way to achieve this...
Thanks...
Compressing Multiple Rows With Null Values To One Row With Out Null Values After A Pivot Transform
Jan 25, 2008I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

can we use a where condition in the statement.If so how can we use it.
Condition (if / Else) In SQL?
Aug 4, 2007Hi all,I'm building a DataSet on Visual Studio and don't know how to do a condition (if/else) with SQL... I have a search form, with a DropDownList and have 2 options in it: Search by Title or Search by Author. If the "Title" is selected, then the value is "title and if "Author" is selected, then the value is "author".Here is what I have right now for the DataSet, as seperated queries but I think I can combine them to be one single query 1.This will returns the songs that matches the title:SELECT LYRICS_PK, LYRICS_TITLE, LYRICS_TITLE2, LYRICS_WRITER, LYRICS_WRITER2, LYRICS_COWRITER, LYRICS_DATE_ADDED, UserId_FK, LYRICS_APPROVED, LYRICS_TYPE, LYRICS_VIEWS, LYRICS_ADDED_BYFROM t_lyricsWHERE ((@LYRICS_TITLE IS NULL) OR (LYRICS_TITLE LIKE '%' + @LYRICS_TITLE + '%') OR (LYRICS_TITLE2 LIKE '%' + @LYRICS_TITLE + '%')) AND (@LYRICS_TYPE = 'title') 2. This returns the songs that matches the author: SELECT LYRICS_PK, LYRICS_TITLE, LYRICS_TITLE2, LYRICS_WRITER,
LYRICS_WRITER2, LYRICS_COWRITER, LYRICS_DATE_ADDED, UserId_FK,
LYRICS_APPROVED, LYRICS_TYPE, LYRICS_VIEWS, LYRICS_ADDED_BY
FROM t_lyrics
WHERE ((@LYRICS_AUTHOR IS NULL) OR (LYRICS_AUTHOR LIKE '%' +
@LYRICS_AUTHOR + '%') OR (LYRICS_AUTHOR2 LIKE '%' + @LYRICS_AUTHOR + '%'))
AND (@LYRICS_TYPE = 'author') This is very inefficient because I have 2 queries, and I need to build 2 ObjectDataSources as well as 2 different GridViews to display the results. I think we can do something likeSELECT .... ... FROM t_lyricsif (@LYRICS_TYPE = 'title') DO THE WHERE CLAUSE THAT RETURNS MATCHES WITH TITLEelse if (@LYRICS_TYPE = 'author') DO THE WHERE CLAUSE THAT RETURNS MATCHES WITH AUTHOR But I don't know how to write that in T-SQL.Any help would be greatly appreciated,Thank you very much,Kenny.
Where Condition
Sep 13, 2004hi
i want to give .text filed of a TextBox to where condition but the result is not correct.
The SQL is like following:
selStr = "SELECT COUNT(*) FROM Users WHERE (Name = usernameTextBox.Text) and (Password = passwdTextBox.Text)"
