SQL Server 2012 :: Dynamic Return Type In A Function

Mar 3, 2015

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'.

Query To Return Records Where One Table Is Void Of Linked Data In Another Table

Feb 13, 2008

I have two tables that share a common identity row. I need to build a query where data that exists in one table does not contain data in the other table. For example, table 1 has columns of Owner_ID, LastName, FirstName and table 2 has columns Auto_ID, Owner_ID, AutoMake. Both tables are joined by the Owner_ID column. I need a query that provides all owners from table 1 who do not have an entry in table 2.

Thanks in advance,

Mark

'Return' Statement In A Function,Get,or Operator Must Return A Value....Question

Aug 28, 2007


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,

'UNION' Return Type

Oct 31, 2007

Hi,i need an opinion on this,...i am using UNION ALL quite a bit in my queries..most of the time these are like 1 line select query,returning "different" type of stuff ..like say query 1 is returning one EmpName  and query 2 is DOB and so on(keeping it simple for example)...i am combining it b/c i find it cumbersome  to call 10 dfferent query to populate  1 structure(table etc) ,rather i wud call one and manipulate the result to fill up that one structure..Is that okay to combine different kind of return types in one (here first row of multi-select query result is empName,second row is DOB and so on...)?????thanks

Return Value Data Type In Asp.net

Feb 24, 2005

I am calling a stored procedure and have an output parameter that I pass back to my asp page. The datatype of the value is nvarchar. When I run the page I get an error "Syntax error converting the nvarchar value 'OK' to a column of data type int". Can a return parameter be anything else other than an integer? Below is my code. Thanks for the help.

Parem = cmd.parameters.add("@Retval",SqlDbType.nvarchar,50)

Return Type Of COALESCE?

Jul 23, 2005

Hi everybody,VARCHAR has a higher precedence than CHAR. If you have a querySELECT COALESCE(c1,c2) FROM T1where c1 is CHAR(5) and c2 is VARCHAR(10), I would expect the returntype to be varchar(10) similiar to UNION. However it turns out tobe CHAR(10). Does anyone know why that is so?Thanks,Steffen

Trick With Return Type

Jul 2, 2007

Hi, I have another question about code in RS.
I have a table cell with FORMAT of "$#,##0,0".
If I have any number in the cell I want to display it.
If I have 0 (zero) I want the cell to be empty.

I know how to do it with an expression:
iif (Fileds!myFiled.Value == 0,"", Fileds!myFiled.Value)

Now I want to do it with a code section:
=Code.hideIfZero(Fileds!myFiled.Value)

The problem is that the function should return Integer and if the value is zero I need to return empty string.

It does't say any thing about returning the string but when it trying to use the format on a string it give me a worning and print #ERORR in the cell.

is there a solution for this?
Do you know the syntax to format the number in the function before the return?
(Sorry for the dumb question but I know C# not VB.net and there is no intelisance in that editor).

Thanks a lot!

Getting Return Type From Stored Procedure

Sep 7, 2006

Hi all,

I am trying to figure out a way to analyze a stored procedure to deduce its output type.

A stored procedure can return values throught one of the following:

1) Using the Return keyword

2) Returning a recordset

3) Throught its Output parameters

4) A combination of 1, 2 or 3

Using the Information_Schema, you can access the SQL code of the stored procedure from, say, VB.Net. From there, I want to know what output type the stored procedure has.

A) for 1), I guess I can parse the code for the 'Return' keyword, but that wouldn't be efficient, for the 'Return' word could be inserted into string values...

B) for 2), it would be difficult to analyze the stored procedure's code to know FOR SURE whether a recordset is returned. You just can't parse for SELECT keywords in complex code...

C) 3) should be easy enough, getting the return parameters types from the Information_Schema.



So, is there an easy way that I missed for achieving this, some object in the .Net Framework that I could use to analyze SQL queries perhaps, or am I doomed to do it the hard way?

Thanks,

-Etienne

Function Return Value

Jun 13, 2004

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

Return @@identity For Another Function

May 14, 2004

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)
)

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")

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

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?

Execute SQl Task Return Decimal Type Result

Dec 3, 2007



I am trying to have an Excecute SQL Task return a single row result set executed on SQL Server 2005.


The query in the Execute SQL Task is:
select 735.234, 2454.123

I get a conversion error when trying to assign to SSIS variables of type Double.
I have nothing configured in the "Parameter Mapping" tab.
I have the two SSIS Double variables mapped to the Tesult Name 0 and 1 in the "Result Set" tab

I don't want to use a for loop enumerator since there is a single row returned.

I simply want to assign these two values to SSIS Double variables (double is the closest match)


I can't even hack this by converting the decimals as string and then using DirectCast to convert them to Double.

Thanks for the help

MS SQL Function Return String - What Am I Doing Wrong?

Jun 6, 2005

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()
End Sub

Function To Return Greater Of Two Numbers

Jun 2, 2008

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?

Thanks
