Question Regarding A Function Return
Apr 7, 2008
I have a function that is using a select case decision structure to arrive at a return value:
[dbo].[fn_Window]
(@Start AS INT,
@End AS INT) RETURNS VARCHAR(5)
AS
BEGIN
SELECT
CASE
/*** Pick up the extended periods here ***/
WHEN @Start = 1 AND @End = 1 THEN 'TRUE'
ELSE 'FALSE'
END
END
**** from here how do I get the function to return true or false? ****
Can I assign the select case result to a variable? If so how?

I'm a Reporting Services New-Be.
I'm trying to create a report that's based on a SQL-2005 Stored Procedure.
I added the Report Designer, a Report dataset ( based on a shared datasource).
When I try to build the project in BIDS, I get an error. The error occurs three times, once for each parameter on the stored procedure.
I'll only reproduce one instance of the error for the sake of brevity.
[rsCompilerErrorInExpression] The Value expression for the query parameter 'UserID' contains an error : [BC30654] 'Return' statement in a Function, Get, or Operator must return a value.
I've searched on this error and it looks like it's a Visual Basic error :
http://msdn2.microsoft.com/en-us/library/8x403818(VS.80).aspx
My guess is that BIDS is creating some VB code behind the scenes for the report.
I can't find any other information that seems to fit this error.
The other reports in the BIDS project built successfully before I added this report, so it must be something specific to the report.
BTW, the Stored Procedure this report is based on a global temp table. The other reports do not use temp tables.
Can anyone help ?
Thanks,

I want to write a function that returns the physical filepath of the master database for its MDF and LDF files respectively. This information will then be used to create a new database in the same location as the master database for those servers that do not have the MDF and LDF files in the default locations.
Below I have the T-SQL for the function created and a test query I am using to test the results. If I print out the value of @MDF_FILE_PATH within the funtion, I get the result needed. When making a call to the function and printing out the variable, all I get is the first letter of the drive and nothing else.
You may notice that in the function how CHARINDEX is being used. I am not sure why, but if I put a backslash "" as expression1 within the SELECT statement, I do not get the value of the drive. In other words I get "MSSQLData" instead of "D:MSSQLData" I then supply the backslash in the SET statement. I assume that this has something to do with my question.
Any suggestions? Thank you.
HERE IS T-SQL FOR THE FUNCTION
IF OBJECT_ID('fn_sqlmgr_get_mdf_filepath') IS NOT NULL
BEGIN
DROP FUNCTION fn_sqlmgr_get_mdf_filepath
END
GO
CREATE FUNCTION fn_sqlmgr_get_mdf_filepath (
@MDF_FILE_PATH NVARCHAR(1000)--Variable to hold the path of the MDF File of a database.
)
RETURNS NVARCHAR
AS
BEGIN
--Extract the file path for the database MDF physical file.
SELECT @MDF_FILE_PATH = SUBSTRING(mdf.filename, CHARINDEX('', filename)+1, LEN(filename))
FROM master..sysfiles mdf
WHERE mdf.groupid = 1
SET @MDF_FILE_PATH = SUBSTRING(@MDF_FILE_PATH, 1, LEN(@MDF_FILE_PATH) - CHARINDEX('', REVERSE(@MDF_FILE_PATH)))
RETURN @MDF_FILE_PATH
END
HERE IS THE TEST I AM USING AGAINST THE FUNCTION
SET NOCOUNT ON
DECLARE
@MDF_FILE_PATH NVARCHAR(1000)--Variable to hold the path of the MDF File of a database.
SELECT @MDF_FILE_PATH = dbo.fn_sqlmgr_get_mdf_filepath ( @MDF_FILE_PATH )
PRINT @MDF_FILE_PATH

What I'm trying to do is provide a solution where users can upload an image and a description, to a database, so I'm trying to insert the title and description then return the @@identity for the image upload function which will name the image like this
image_23.jpg (23 being the @@identity) resize it and save it to specified directory
I cant seem to get the identity to return to my script.
This is my SP
CREATE PROCEDURE SP_Insertad
(
@catid int,
@subcatid int,
@areaid int,
@uid int,
@adtitle varchar(255),
@addescription varchar(1000)
)
AS
Insert Into Tbl_ad
(ad_title, ad_description,ad_area,ad_ui_id,ad_active,ad_date,ad_ct_id,ad_sc_id,ad_location)
VALUES
(@adtitle,@addescription,@areaid, @uid, 0,convert(varchar, GETUTCDATE(), 101), @catid, @subcatid, 1)
select @@identity
return
GO
I tested in query analyser, and it works fine, so It must be my code. this is my function
Sub Insert_pic(sender as object, e as eventargs)
Dim catid = Request.form("ddcats")
Dim subcatid = Request.form("subcatrad")
Dim adtitle = Request.Form("txttitle")
Dim AdDescription = Request.form("txtdescription")
Dim uid = getUID(Context.User.Identity.Name)
Dim areaid = Request.form("ddarea")
SQLConnect = new SqlConnection(ConfigurationSettings.Appsettings("mydB"))
SQLCommander = New SQLCommand("SP_INSERTad", SQLConnect)
SQLCommander.Commandtype = Commandtype.StoredProcedure
SQLCommander.Parameters.add("@adtitle", adtitle)
SQLCommander.Parameters.add("@addescription", addescription)
SQLCommander.Parameters.add("@catid", catid)
SQLCommander.Parameters.add("@subcatid", subcatid)
SQLCommander.Parameters.add("@uid", uid)
SQLCommander.Parameters.add("@areaid", areaid)
'// this section not working right, it wont write return id
Dim paramreturn as SQLParameter
paramreturn = SQLCommander.Parameters.Add("ReturnValue", SQLDBType.Int)
ParamReturn.Direction = ParameterDirection.ReturnValue
response.write(SQLCommander.Parameters("ReturnValue").Value)
SQLConnect.open()
SQLCommander.ExecuteNonQuery()
SQLConnect.close()
End sub
Can anybody see anything I missing? I appreciate any imput

Hi,
I basically do not want to return a null value as a result of using a sum function (using sum against 0 rows).
Is there a common way to avoid this?

Cannot see where I am going wrong. I always get a value of 0. I know my function works correctly, so it must be the VB.
CREATE FUNCTION [dbo].[getNextProjectID] ()
RETURNS varchar(10) AS
BEGIN
'''''''''''''''''''...........................
DECLARE @vNextProjectID varchar(10)
RETURN @vNextProjectID
END
Sub LoadNextProjectNumber()
Dim vProjectID As String
Dim cmd As New SqlClient.SqlCommand()
cmd.Connection = sqlConn
cmd.CommandText = "getNextProjectID"
cmd.Parameters.Add("@vNextProjectID", vProjectID)
cmd.Parameters("@vNextProjectID").Direction = ParameterDirection.ReturnValue
cmd.ExecuteScalar()
vProjectID = cmd.Parameters("@vNextProjectID").Value
txtProjectID.Text = vProjectID
cmd.Dispose()

Greetings,
Is there anything new on returning max of two values in SQL 05? There seems to be nothing I have searched everywhere. Only option might be to create my own UDF or do a CASE statement, but I could not believe my eyes there is no such thing?

I have created a function to return values, which works fine, but I can't do calculations in it.
CREATE FUNCTION [dbo].[tf_Asset_Portfolio](@deal_id int,
@as_of_date datetime)
RETURNS TABLE
AS
RETURN ( SELECT DISTINCT dbo.Assets.issue_id, SUM(DISTINCT dbo.Assets.par_amount) AS par_amount, SUM(DISTINCT dbo.Assets.par_amount) AS market_value
FROM dbo.Issue INNER JOIN
dbo.Assets ON dbo.Issue.issue_id = dbo.Assets.issue_id INNER JOIN
dbo.Issuer_Rating_History ON dbo.Issue.issuer_id = dbo.Issuer_Rating_History.issuer_id
WHERE (dbo.Issuer_Rating_History.as_of_date <= @as_of_date)
GROUP BY ALL dbo.Assets.issue_id, dbo.Assets.deal_id, dbo.Issue.default_date
HAVING (dbo.Assets.deal_id = @deal_id) )
I need to do calculations on market value based on the default date.
If default date isn't specified then it should be 100% of par amount.
If default date is less than one year ago - 65% of the par_amount.
If default date is one or more years ago - 0.
I have no idea about how to do this and everything I try wont work.
I created another function to do the calculations and this seems to work, but it only does one record instead of all of them.
CREATE FUNCTION dbo.tf_Asset_Portfolio2
(@deal_id int,
@as_of_date datetime)
RETURNS @Market TABLE
(issue_id int, par_amount money, market_value money)
AS
BEGIN
DECLARE @ReturnDate datetime
DECLARE @DD datetime
DECLARE @PA money
DECLARE @MV money
DECLARE @ID int
DECLARE @DateD int
SELECT TOP 1
@ReturnDate = LAST_BATCH
FROM master..sysprocesses
WHERE SPId = @@SPID
SELECT @ID = issue_id FROM Assets WHERE Assets.deal_id = @deal_id
SELECT @PA = SUM(DISTINCT par_amount) FROM Assets WHERE Assets.issue_id = @ID AND Assets.deal_id = @deal_id
SELECT @DD = default_date FROM Issue WHERE Issue.issue_id = @ID
SET @DateD = DateDiff("yyyy", @DD, @ReturnDate)
If @DD = Null
BEGIN
SET @MV = @PA
END
Else If @DD > @ReturnDate
BEGIN
SET @MV = @PA
END
Else If @DateD < 1
BEGIN
SET @MV = @PA * .65
END
Else If @DateD >= 1
BEGIN
SET @MV = 0
END
insert into @Market
(issue_id, par_amount, market_value)
values
(@ID,@PA,@MV)
RETURN
END
I need to combine the functionality of being able to return mutliple records that isn't in the 2nd function and being able to calculate the market value which isn't in the first one. Please help. Thank you in advance.

I have created the following user function :-
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER function [dbo].[GetBillPrice](@BillLineID int)
returns float
as
begin
DECLARE @BillPrice float
SET @BillPrice = (
SELECT ((CAST(T_BillValueAndTax.BillValueAndTaxBillValue as float))+(CAST(T_BillTax.BillTaxTax1Value as float)) +(CAST(T_BillTax.BillTaxTax2Value as float)))
FROM T_BillLine

INNER JOIN T_BillTax on T_BillTax.BillTaxID = T_BillValueAndTax.BillTaxID_Bill
WHERE T_BillLine.BillLineID = @BillLineID)
return ABS(@BillPrice)
end
No matter how I try to return the @BillPrice value, the value is rounded to the nearest whole number. For instance if the value is calculated as 198.75 the value returned is 199.0
When I execute the function in Query Anlayser the correct value of 198.75 is returned.
Any help in solving this would be greatly appreciated.

I have a function that I need to call from an execute sql task. I want to bind the return value from the function to an ssis variable.
Can someone please show me an example of what the function syntax needs to look like in order for this to work? I know that with sp's, you need to explicitly state the column names.
I have tried many things without success.

Hi,
I am trying to find a way to return the result of an EXEC(*sqlstring*) from a function. I can return the tsql but not the result of an execute.
This is my function:
ALTER FUNCTION [dbo].[ReturnPickItemValue]
(
-- Add the parameters for the function here
@TypeID int,
@CaseID int
)
RETURNS varchar(max)
AS
BEGIN
-- Declare the return variable here
DECLARE @RTN varchar(max)
IF(SELECT IncludeDates FROM TBL_LU_PICK WHERE PickTypeID = @TypeID) = 1
BEGIN
SET @RTN = 'SELECT PickItem I +
CASE D.IsStartDateEstimated
WHEN 0 THEN CAST(StartDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsStartDateEstimated, 0) as varchar)
END +
CASE D.IsEndDateEstimated
WHEN 0 THEN CAST(EndDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsEndDateEstimated, 1) as varchar)
END
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_PICK P ON P.PickItemID = I.PickItemID
LEFT JOIN TBL_PickDates D ON D.PickID = P.PickID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND P.CaseID = ' + CAST(@CaseID as varchar)
END
ELSE
BEGIN
SET @RTN=
'SELECT I.PickItem
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND CaseID = ' + CAST(@CaseID as varchar)
END
RETURN @RTN
END
Each time I try " RETURN EXEC(@RTN) " or something similar I get an error.
I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error.
Anyone with any ideas?

Hi,
I have an assembly that contains the following function:
Public Class Lookup
<SqlFunction()> _
Public Shared Function MyTest() As Integer
Return System.Data.SqlTypes.SqlInt64.Null
End Function
End Class
Then in SSMS:
CREATE ASSEMBLY IRS_MyTest
FROM '\machine empmyAssembly.dll'
GO
CREATE FUNCTION dbo.MyTest() RETURNS INT
AS EXTERNAL NAME IRS_MyTest.[MyClass].MyTest
GO
when I run:
SELECT dbo.MyTest()
the following is returned:
Msg 6522, Level 16, State 2, Line 1
A .NET Framework error occurred during execution of user defined routine or aggregate 'MyTest':
System.Data.SqlTypes.SqlNullValueException: Data is Null. This method or property cannot be called on Null values.
System.Data.SqlTypes.SqlNullValueException:
at System.Data.SqlTypes.SqlInt64.get_Value()
at System.Data.SqlTypes.SqlInt64.op_Explicit(SqlInt64 x)
at Informed.DCLG.IRS.SQL.IncidentTransform.Lookup.MyTest()
Can anyone please advise on how to return back a null value. Currently, my only other option is to return nothing (actually returns 0) and then wrap this up to convert the value to null - not ideal.
Thanks,
Jan.

I used a function to create dataset as below:
Public Function GetSQLDataSet(ByVal SQL As String) As DataSet
......
MyConnection = New SqlConnection(MyConnectionString)
MyCommand = New SqlCommand(SQL, MyConnection)
MyDataSet = New DataSet
MySQLDataAdapter = New SqlDataAdapter(MyCommand)
MySQLDataAdapter.Fill(MyDataSet)
......
End function
It works fine.
How to code a function to return a dataset in which there are two tables and relationship?

I have rather simple CLR function:
[SqlFunction(IsDeterministic = true, DataAccess = DataAccessKind.None)]
public static SqlString GetUserName()
{
return (SqlString)WindowsIdentity.GetCurrent().Name;
}
When I get result from .NET console app, I get correct answer "JungleSektor". However, when SQL Server executes this code, it gives me "NT ServiceMSSQL $ SQL2014". How to get correct result?

I have created a function that will check whether the data is null or not. If its null then it will display that as No data else it will display the original value. Below is the function
GO
Object: UserDefinedFunction [dbo].[fnchkNull] Script Date: 3/4/2015 12:01:58 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
[code]...
The code is working good. However i want the return type to be dynamic. If the data type supplied is integer then i want to return a integer value like 0 if its null. if the data value is varchar then i want to return 'No Data'.
