Ignore NULL StoredProcedure Parameters
Mar 18, 2008
Hi,
I do have a stored procedure with parameters inside. I just want to ignore those parameters that are NULL so that my WHERE clause will not execute them anymore. Here's my code:
CREATE PROCEDURE SEARCHPATIENT
@patnCode varchar(10) = NULL,
@patnSurname varchar(20) = NULL,
@patnGivenName1 varchar(20) = NULL
AS
SELECT....
FROM ...
WHERE patnCode=@patncode AND
patnSurname =@patnSurname AND
patnGivenName1 =@patnGivenName1
BUT...
If the user passes @patnSurname as NULL, I got an SQL error message:
"There was an error executing the query.. Timeout expired... ". I was hoping I could write an WHERE clause where IT WILL ONLY EXECUTE those parameters WITH VALUE and IGNORE those NULLs.
Can someone help me on this?
Can I use IF THEN ELSE statement inside the WHERE clause?
Can I use CASE STATEMENT inside the WHERE clause?
Thanks in advance.
Joseph

I know it's unbelievable, but i didn't ever use SP before. Sorry for this noobish question, don't beat me for this - please ;-)
In my SELECT Query i like to have some (WHERE) paramteters le's say: ID, NAME and AGE. I allways programmicali generate a WHERE statement in relation to which parameters I really get, because not allwasy i get all the parameters together. This is fine for "normal" Tables.
How does this work with SP? If I don't get NAME, do I set the SP-Parameter NAME to null to unconsider it? Or do I have to make some IF statements in the SP to check, if NAME has some value?
Thanks for a short hint!

Hi,
I have a query like this one
SELECT expense_id, CAST(expense_id AS char(10)) + ' - ' + CAST(trip_km AS char(5))+ ' - ' + CAST(expense_amount AS char(5)) + ' - ' + charge_centre AS ExpenseDesc
If charge center is null, I need to ignore this field. How can I achieve this? The reason is that if any of the field is null, it will return ExpenseDesc as null.
Thanks

Using SQL2000. According to Books Online, the avg aggregrate functionignores null values. ((3+3+3+3+Null)/5) predictably returns Null. Isthere a function to ignore the Null entry, adjust the divisor, andreturn a value of 3? For example:((3+3+3+3)/4) after ignoring Nullentry.If there's more than one null value, then adjust divisor accordingly.For example: ((5+5+5+4+Null+5+5+Null)/8) would be ((5+5+5+4+5+5)/6)after nulls ignored.Thanks for any help or advice.

Is there a way to ignore a column/variable when the whole result set for the applied filter (where) is null?
Not all clients have data for every variable, i.e. some variables are client specific. There are too many variables and clients to amend the select query every time so I just want to ignore a col if its null.
I hope that makes sense (my inability to describe it might explain my inability to find anything related to it!)
The next step would be to run all clients' data in one go using, I believe, a cursor, but one step at a time!

I have a stored procedure which accepts 3 arguments that are used in the WHERE clause of a SELECT Statement
CREATE PROCEDURE [dbo].[MyProcedure] @argYear INT, @argMonth INT, @argDay INT
AS
SELECT *
FROM MyData
WHERE
MyData.Year = @argYear AND MyData.Month = @argMonth AND MyData.Day = @argDay
The problem that I am having is @argDay is an "optional" argument. If @argDay is NULL then I want to basically ignore the "AND MyData.Day = @argDay" condition.
Is there an easier way to do this than:
IF @argDay is NULL
SELECT *
FROM MyData
WHERE
MyData.Year = @argYear AND MyData.Month = @argMonthELSE
SELECT *
FROM MyData
WHERE
MyData.Year = @argYear AND MyData.Month = @argMonth AND MyData.Day = @argDay
END IF
Thanks

Hi,
I am starting to use reporting services and I created a report that takes 4 parameters for a Filter on the dataset.
The idea is the create snapshot nightly and then display the report filtered based on parameters to users.
I'd like that the filter be ignored for a parameter if the parameter is passed as NULL,
Right now I defined it this way :
Left =Fields!RegionCode.Value
Operator =
Right =IIF(IsNothing(Parameters!RegionCode.Value),Fields!RegionCode.Value,Parameters!RegionCode.Value)
I do this for the 4 parameters that are passed, if they are null, make then equals to the field.
I was wondering if there is a way to ignore the whole parameter all together, I would guess it'll be faster to execute.
Thanks

How do you configure a multi-value parameter so it will allow the user to not enter the parameter?
I'm using integer multi-value parameters. I can't set the parameter to allow null, and when I preview the report and leave the parameter blank, it tells me to enter at least one value. I tried it with string parameters, and the report just doesn't run in preview if you don't enter any values, even if you choose "allow blank".
How do you specify a multi-value parameter to allow "empty" or "null"?

I am using a SQLDataSource with Stored Procedures. The Select, Insert and Update all work well. However I cannot get the delete to work. My stored procedures are tested and verified and the parameter names are the same as the source columns. When I try to run the delete an error that the stored procedure expects the parameter @locationStationId, however this value passes properly for the Update command?!? I tried to change the parameter to original_locationStationID to pass the original value, however this result in Null being passed for the parameter.
I cannot understand why this works for Update and passes the location ID, but will not work for DELETE. Can anyone shed any light onto the matter?
Thanks.OldValuesParameterFormatString="original_{0}" UpdateCommand="spUpdateLocation" UpdateCommandType="StoredProcedure"

I'm new to SQL Server, so if I'm doing anything stupid don't bemean :)I have a procedure that I use to return data based on optionalparameters. It works fine, except when the underlying data contains anull on one if the fields being searched.My system uses a default wildcard for all parameters, so this excludessuch records. I need a way to add in " OR fldName IS NULL " where theparameter is empty or '%'. I've looked at using CASE WHEN, but itdoesnt seem to like SQL Keywords being part of the WHEN clause.I'd hate to have to resort to executing concatonated strings made fromIF and ELSE statements. Just too messy and not at all pretty!Any Ideas? Here's what I've got:ALTER PROCEDURE [dbo].[procFindUnits]@strUnitIDnvarchar = '%',@strProjectNamenvarchar = '%',@strAddressnvarchar = '%',@strTenancynvarchar = '%',@strTenurenvarchar = '%'ASBEGINSET NOCOUNT ON;SELECTtblUnits.strUnitID,tblProjects.strProjectName,qryAddresses.Address_OneLine,lkpTenancyTypes.strTenancyType,lkpTenureTypes.strTenureTypeFROM tblUnits INNER JOINtblProjects ON tblUnits.intProjectID = tblProjects.intProjectIDLEFT OUTER JOINlkpTenancyTypes ON tblUnits.intTenancyType =lkpTenancyTypes.intTenancyType LEFT OUTER JOINlkpTenureTypes ON tblUnits.intTenureType =lkpTenureTypes.intTenureTypeID LEFT OUTER JOINqryAddresses ON tblUnits.strUnitID = qryAddresses.strUnitIDWHERE(tblUnits.strUnitID LIKE @strUnitID)AND (tblProjects.strProjectName LIKE @strProjectName)AND (qryAddresses.Address_OneLine LIKE @strAddress)AND (lkpTenancyTypes.strTenancyType LIKE @strTenancy)AND (lkpTenureTypes.strTenureType LIKE @strTenure)END

i have a form where filter information is going to be keyed/selected.
the data from that form is copied into a struct regardless of whether each field has data in it or not (eg firstname may have been entered but not lastname,
so the struct would contain firstname = 'john' and lastname = null)
i then want to build an sql statement (not using stored procedures but just direct sql) from this struct data but obvioulsy can't just have
a statement that says 'select ID from theTable where firstname='john' AND lastname=''" as this won't bring back the right info, if anything at all.
i normally build the statements like this
Code Block
string sql = "select ID from MembersTemp where FirstName = '{0}'";
SqlCommand cmd = new SqlCommand(string.Format(sql, FirstName), _con);
_con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
List<int> result = new List<int>();
while (rdr.Read())
{
etc....
so really, what's the best way of building an sql statement where some search parameters won't hold a value and therefore need ignoring.
also, whilst i'm here, i use viz studio 2005 and sql server 2005 (express??), so that does mean i'm using TSQL as well??

I have created a report with a stored proc which takes a parameter whose default value is null. Now when I run my stored proc in Enterprise Manager without any params I get 4 rows otherwise with proper parameter I get 2 rows.
Now I set the params value to allow for Null and blank values. When I run the report if I provide parameter value it works fine but if i try to run it without any param it shows an empty report while the stored proc running without params shows 4 rows.
I have earlier sucessfully created reports where stored procs had 4 params out of which 3 where defaulted to null. And so I set the allow nulls, Allow Blanks values to be true for those params in Rep services. So when I selected value for 1st param and ran the report I got the desired report. But this time I have only one param which can be null. But its not working.
Thanks in advance.

I am using version 9.00.2047.00 SP1 of Visual Studio 2005.
Using ADO.NET, I have been unable to get the Execute SQL task to successfully return the value of an output parameter defined as varchar or nvarchar when the value is null. No other data types seem to have this problem, including the sql_variant data type.
Here is the stored procedure I am calling:
create proc spx
@in int = null output,
@vc nvarchar(10) = null output,
@dt datetime = null output
as
select
@in = null,
@vc = null,
@dt = null
return
The variables to which the three output parameters return their values have a data type of Object. The task runs fine when the integer or datetime parameters are used, and the variables can be identified as null using IsDBNull. But as soon as the nvarchar (or varchar) parameter is included, the task fails with this message:
"The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 1 ("@vc"): Data type 0xE7 has an invalid data length or metadata length."
I have seen a couple of postings that sound similar to this problem, but so far I have found no resolution. Any advice would be much appreciated.
Thanks,
Ron Rice

Hi,
I have a CLR function that throws an error if one of the parameters is NULL. Am I using the IsNullable tag correctly or am I supposed to do this another way? The function simply formats decimal values using .NET culture information and returns a string. Thanks very much for any help. -- Erik
[Microsoft.SqlServer.Server.SqlFunction(IsDeterministic=true, DataAccess=DataAccessKind.None)]
[return: SqlFacet(MaxSize = 30, IsNullable=true)]
public static string FormatGeneralDecimal([SqlFacet(Precision = 28, Scale = 8, IsNullable = true)] SqlDecimal sqlDc,
[SqlFacet(MaxSize = 10)] string cultureName)
{
string result = null;
if (!sqlDc.IsNull)
{
CultureInfo ci = CultureInfo.CreateSpecificCulture(cultureName);
result = sqlDc.Value.ToString("G", ci);
}
return result;
}
It works great unless I call it with a NULL value for sqlDc, in which case I get this:
select [dbo].[FormatGeneralDecimal](NULL, 'de-DE')
Msg 6522, Level 16, State 2, Line 1
A .NET Framework error occurred during execution of user-defined routine or aggregate "FormatGeneralDecimal":
System.Data.SqlTypes.SqlNullValueException: Data is Null. This method or property cannot be called on Null values.

I have an event:
Private Sub SqlDataSourceIncome_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourceIncome.Deleted
Dim command As SqlClient.SqlCommand
command = e.Command
If command.Parameters("@nReturnCode").Value <> 0 Then
DROPDEAD()
End If
That fires from:
<DeleteParameters>
<asp:Parameter Name="nDeletebyId" Type="Int64" />
<asp:Parameter Name="nOtherId" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnCode" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnId" Type="Int64" />
</DeleteParameters>
End Sub
When I:
GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex)
But nReturnCode is ALWAYS NULL... I even did a stored procedure that just:
ALTER PROCEDURE [dbo].[sp_nDeletebyId]
@nReturnCode bigint output,
@nReturnId bigint output AS
SET @nReturnCode = 0
SET @nReturnId = 0
And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock. Has anyone seen this before? The above sample stored proc did return 0 when executed one the server...
and, BTW, the row is deleted!

Hey. 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
)

Hi
I am New to Sql Server. Now i have to write two stored procedures.
Here are my requirements. If any one help please.
1)People often ask me to do this as well... change the name of the underwriter. For Mortgage Network underwriters (different than MGIC underwriters) all you need to do is:
Update mnetwork..unw_Nola set underwriter='<underwriters username>' where LoanID='<LoanID>'
So, I need you to write a stored procedure that will do exactly that. If you don't enter a loanID or username, the stored procedure should tell you that it can't complete the task and why. Also, the list of underwriters can be found in:
select LoginName from mnetwork..unw_LoginLookup where UnderwriterName = '<Name on the email>'
So for this one, you would select where underwriterName='John Brennan'.
For most usernames, it's just first initial last name (jbrennan in this case). You can make the stored procedure to both, if you want. If you enter an underwriter name, then it will translate to the loginname. If you enter the login name, it will just use that. You don't have to do all of that if you don't want. Just make sure the procedure verifies that the username is correct (in the table) and that is enough.
Tables for this storedprocedure:
Table Name:mnetwork..unw_Nola
Table Fields:LoanID,ConditionSet,Status,Revised,RevisedBy,PDFNOLA,MonthlyIncome,DocExpDate,Notes,
Underwriter,rowguid,ApprovedDate.MovedToCentera,FK_UserID,RecordDate
TablName:mnetwork..unw_LoginLookup
Table Fields: [LoginLookupID], [LoginName], [UnderwriterName], [FirstName], [LastName], [Title], [Signature], [Address1], [Address2], [Addr1], [Addr2], [City], [State], [Zip], [Phone], [Phone2], [Fax], [Email], [DefaultSet], [rowguid], [FK_UserID], [RecordDate], [Createdby], [LastUpdated], [UpdatedBy]
2)1. Block this loan
2. Grant me access to this blocked loan.
So, I need you to write either one or two stored procedures that will accomplish the following:
When a loan needs to be blocked, it needs to be added to the mnetwork..sec_BlockedLoans table
When a person needs access to that loan, their username needs to be added to the mnetwork..sec_LoanAccess table.
Tables:
1) SELECT [LoanID], [Username], [Grantor], [GrantDate] FROM [mnetwork].[dbo].[sec_LoanAccess]
2) SELECT [LoanID], [Added] FROM [mnetwork].[dbo].[sec_BlockedLoans
any one can help to write these stored procedure.
Thanks,
JT

Hi everyone!I tried to set my SqlDataSource's SelectCommandType to be a stored procedure. However the SqlDataSource failed to cache it. But if I just copy paste my stored procedure's content to my SqlDataSource's SelectCommand property, the cache just works. Is "StoredProcedure" as the "SelectCommandType" is not supported when caching the data? Or am I missing something here? Please help.

2 Dim cnn As New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
3 Dim cmd As New SqlCommand
4 cmd.CommandText = "usp_responses_sel"
5 cmd.CommandType = Data.CommandType.StoredProcedure
6
7 ' Fill usp_ with Parameters
8 cmd.Parameters.AddWithValue("QuestionID", QuestionID)
9 cmd.Parameters.AddWithValue("LocaleID", LocaleID)
10 cmd.Parameters.AddWithValue("GroupingNum", GroupingNum)
11
12 Dim da As New SqlDataAdapter
13 da.SelectCommand = cmd
14 Dim ds As New DataSet
15 da.Fill(ds, "response")
16 Return ds
17 End Function
So my issue is with line 15 [da.Fill(ds, "response")]. I pulled this function from somewhere else and am trying to tailor it to my needs. However, I do not understand what I need to do with this line and it keeps bombing out. I thought this references the DB Table but in my case, the SP has several tables joined together. Is this how I reference it from the calling source code? Please assist.
Also, I am having problems understanding the binding process from the calling source. Here is my code that calls the function:1 Dim ds As DataSet = GetDataSet(CType(e.Item.DataItem("question_id").ToString, Integer), QuestionTypeID.Value, intLocale, 2)
2 rblResponses2.DataSource = ds
3 rblResponses2.DataBind()
What do I need to do with it from here and how can I work with it after it's bound?
Thanks
