I have created a store procedure, but the requirement is function because by using this function we need to add columns in a table with SSIS.
I have tried to create function, but the error I am facing is select statement can not return data.
CREATE PROCEDURE SP_STAT_CURR
(
@I_NET_AMOUNT NUMERIC(10,3),
@I_DOCUMENT_CURR VARCHAR(3),
@I_TARGET_CURR VARCHAR(3)
[code]....
Does MS-SQL allow us to create an user-defined function within the stored-procedure script? I have been getting errors. It's my first time using the user-defined function with stored-procedure. I welcome your help.
Code:
CREATE FUNCTION ftnVehicleYearFormattor (@sValue VARCHAR(2))
RETURNS VARCHAR(2)
AS
BEGIN
IF (LEN(@sValue) < 2)
SET @sValue = '0' + @sValue
RETURN @sValue
END
Thanks...
Hi.I'm really new to MSSQL, so therefore my question can sound stupid.Is it possible to use a function written in a module in MS-ACCESS in astored procedure?Or how can it be done, it is a complicated function with loop and more.I'll appreciate all answers also negatives ones.TIAJørn
View 1 Replies View RelatedHello friends,
I want to use my user defined function in a stored procedure.
I have used it like ,
select statement where id = dbo.getid(1,1,'abc')
//dbo.getid is a user defined function.
procedure is created successfully but when i run it by exec procedurename parameter
I get error that says
"Cannot find either column "dbo" or the user-defined function or aggregate "dbo.getid", or the name is ambiguous."
Can any body help me?
Rgds,

I seem to be getting tasks that I am not familiar with these days. I am a
guy that has coded it all in the asp page or in the code behind in .NET.
This problem is outlined below and I need a help / advice on doing this. I
had the flow of the 3 parts to it expanded below. A call is made to a Stored
Procedure, The SP then calls a user defined function that runs SQL, this
returns a 1 or 0 to the SP which then returns the value back to the call on
the asp page. This is a lot I know but it is the way the lead guy wants it
done. Any help so I can keep most of the hair I have left is appreciated :-)
Short list of process flow:
1. Form.asp calls to rx_sp_HasAccessToClient in SQL SERVER
2. rx_sp_HasAccessToClient then calls ab_HasAccessToClient
3. ab_HasAccessToClient runs SQL command on db and sends return bit back to
rx_sp_HasAccessToClient
4. rx_sp_HasAccessToClient then sends this back to the call in the Form.asp
page
5. Form.asp then checks the Boolean and if 1 then show or if 0 then deny.

this is to be done so far.

View 3 Replies View RelatedI have several UDFs created. Inside one of the UDFs I need to execute a dynamic SQL statement and then take that result and do something else with it, before returning the final value.
I know you can not execute a stored proce from inside a function. I also know you can not use the EXEC statement.
I did read that you could use an external stored procedure and/or managed CLR procedures inside a function.
I have created a managed procedure CLR (C#) that simply executes a passed statemetn and returns the value to the calling routine. I have this all coded and is working fine.
However, I am struggling with knowing how to call this CLR procedure from inside my function, seeing how I can not use EXEC statement.
Any advice on how to do this?

Does anyone know where to find or how to write a quick user defined fucntionthat will return a table object when passed the string name of the tableobject. The reason why I want dynamicallly set the table name in a storedprocudue WITHOUT using concatination and exec a SQL String.HenceIf @small_int_parameter_previous = 1 then@vchar_tablename = "sales_previous"else@vchar_tablename = "sales"Endselect * from udf_TableLookup(@vchar_tablename )So if I pass 1, that means I want all records from "sales_previous"otherwise give me all records from "sales" (Sales_Previous would last yearssales data for example).udf_TableLookup would I guess lookup in sysobjects for the table name andreturn the table object? I don't know how to do this.I want to do this to avoid having 2 stored procedures..one for current andone for previous year.Please respond to group so others may benfiit from you knowledge.ThanksErik

I have several stored procedures with parameters that are defined withuser defined data types. The time it takes to run the procedures cantake 10 - 50 seconds depending on the procedure.If I change the parameter data types to the actual data type such asvarchar(10), etc., the stored procedure takes less that a second toreturn records. The user defined types are mostly varchar, but someothers such as int. They are all input type parameters.Any ideas on why the stored procedure would run much faster if notusing user defined types?Using SQL Server 2000.Thanks,DW

I have UDF in a database on SQL2000 server. Is it possible to call this UDF from other server (SQL2005)? I did setup a linked server to SQL2000
Call to the following function returns an error:
Msg 207, Level 16, State 1, Line 1
Invalid column name 'srv2000'.
select [srv2000].db_test.dbo.F_TEST()
This is my problem: I do not know how to get the servername from a C# user defined function . Is this possible?
I am writing a User Defined Function (UDF). Inside of this user defined function I need the name of the databaseserver that it is running on. Does anyone have an idea how I might do this? Is there an enviromental variable that I could access within the C# code I use to write the UDF?
I could always use a parameter to pass in the name of the server, but I would like to have as few parameters as possible.
Thanks in advance,

Is it possible to define your own function? If so could you give me an example.
Keep in mind that I said in SQL Server 2000. I want no CLR SQL Server 2005 solutions.

EXEC master.dbo.xp_msver ProductVersion can be used to return the server version in a resultset. I need this to do some conditional coding between varchar and varchar(max) in a UDF, so size of the text I return must be different between the SQL2000 and SQL2005.
I cant call an xp_ that returns a resultset within a UDF can I, so how can I get the SQL version?
I have a User Defined Function in my SQL Server 2000 database which takes a string and adds an integer quantity to it. The function basically takes the string (string because of first character and spaces) and adds an integer to it creating a new number (starting number and ending number concept).If I pass in a string that has a letter for the first character, it works fine. However, if the first character is an integer it trims out all 0s and whitespace and ruins the necessary formatting. Note, the formatting is always the same - x xxx xxxx xx. Any help or ideas would be appreciated.Example:D 499 8900 01 plus a Quantity of 10 returns D 499 89000 11 which is perfect.However,0 076 0000 03 plus a Quantity of 1 returns 764 764 (it should be 0 076 0000 04)------------------------------------CREATE FUNCTION [dbo].[NEW_End_NR2]( @OldStr as char(20), @Quantity int )RETURNS @NewNR_Tbl TABLE (New_EndNr char(20) primary key)AS BEGIN DECLARE @NewStr char(20) DECLARE @addNr integerBEGIN Set @addNr = @Quantity set @NewStr = (select REPLACE(@OldStr,left(@OldStr, 1),'')) set @NewStr = (select REPLACE(@NewStr,' ', '')) + @addNr set @NewStr = (SELECT left(@OldStr, 1) + SPACE(1) + left(@NewStr,3) + SPACE(1) + left(REPLACE(@NewStr, left(@NewStr,3), ''), 4) + SPACE(1) + left(REPLACE(@NewStr, left(@NewStr,7), ''), 3)) BEGIN INSERT INTO @NewNR_Tbl (New_EndNr) VALUES(@NewStr) END END RETURNEND

2) After I clicked on the |OK| button, the following message appeared:

What I want to do is return a row of data when my query doesn't return a record. I have two tables:
CREATE TABLE dbo.abc(
SeqNo smallint NULL,
Payment decimal(10, 2) NULL
) ON PRIMARY
[Code] ....
So when I run the following query:
SELECT 'abc' + '-' + CAST(SeqNo AS VARCHAR) + '-' + CAST(Payment AS VARCHAR) FROM abc WHERE SeqNo = 1
UNION
SELECT 'def' + '-' + CAST(SeqNo AS VARCHAR) + '-' + CAST(Payment AS VARCHAR) FROM def WHERE SeqNo = 1
abc-1-200.00
abc-1-500.00
As you can see since 1 doesn't exists in table 'def' nothing is returned as expected. However, if a row isn't returned I want to be able to enter my own row such as
abc-1-200.00
abc-1-500.00
def-0-0.00
Got some errors on this one...
Is Rand function cannot be used in the User Defined function?

If you use the LEFT() function for example it provides intellisense support for some of the required parameters.
Is there a way to get that same descriptive text in user defined functions?
Some comment block you define when creating the function?
I have a UDF that takes my input and returns the next valid business day date. My valid date excludes weekends and holidays.
It works perfect except for one issue. It doesn't check to see if today's date is a holiday.
I pass a query to sql server like so " select dbo.getstartdate('01/ 10/2007',2)"
It then moves ahead two business days and returns that date.
Here is the current code. Hopefully someone can tell me how to do the holiday check on the current date.
I really don't want to rewrite the whole script .
