User Defined Function: Convert String Value Of Table To Table Object
Jul 20, 2005
Does anyone know where to find or how to write a quick user defined fucntion
that will return a table object when passed the string name of the table
object. The reason why I want dynamicallly set the table name in a stored
procudue WITHOUT using concatination and exec a SQL String.
Hence
If @small_int_parameter_previous = 1 then
@vchar_tablename = "sales_previous"
else
@vchar_tablename = "sales"
End
select * 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 years
sales data for example).
udf_TableLookup would I guess lookup in sysobjects for the table name and
return 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 and
one for previous year.
Please respond to group so others may benfiit from you knowledge.
Thanks
Erik

I have this function in access I need to be able to use in ms sql. Having problems trying to get it to work. The function gets rid of the leading zeros if the field being past dosn't have any non number characters.For example:TrimZero("000000001023") > "1023"TrimZero("E1025") > "E1025"TrimZero("000000021021") > "21021"TrimZero("R5545") > "R5545"Here is the function that works in access:Public Function TrimZero(strField As Variant) As String Dim strReturn As String If IsNull(strField) = True Then strReturn = "" Else strReturn = strField Do While Left(strReturn, 1) = "0" strReturn = Mid(strReturn, 2) Loop End If TrimZero = strReturnEnd Function

I'm trying to create a simple function that will do a count on a table. I want to pass the table name in form of a parameter to the variable and this function will return the count as an int. See my function below...
CREATE FUNCTION count_rows (@tablename varchar(100)
RETURNS int AS
BEGIN
DECLARE @emp_count AS int
declare @declaration varchar(100)
[Code] ....
The errors I am getting are as follows:
Msg 102, Level 15, State 1, Procedure count_rows, Line 3
Incorrect syntax near 'RETURNS'.
Msg 102, Level 15, State 1, Procedure count_rows, Line 10
Incorrect syntax near '@declaration'.
Msg 178, Level 15, State 1, Procedure count_rows, Line 14
A RETURN statement with a return value cannot be used in this context.

Hello,
We have created several Table Valued User Defined Functions in a Production SQL Server 2005 DB that are returning large (tens of thousands of) rows obtained through a web service. Our code is based on the MSDN article Extending SQL Server Reporting Services with SQL CLR Table-Valued Functions .
What we have found in our implementations of variations of this code on three seperate servers is that as the rowset grows, the length of time required to return the rows grows exponentially. With 10 columns, we have maxed out at approximately 2 500 rows. Once our rowset hit that size, no rows were being returned and the queries were timing out.
Here is a chart comparing the time elapsed to the rows returned at that time for a sample trial i ran:
Sec / Actual Rows Returned
0 0
10 237
20 447
30 481
40 585
50 655
60 725
70 793
80 860
90 940
100 1013
110 1081
120 1115
130 1151
140 1217
150 1250
160 1325
170 1325
180 1430
190 1467
200 1502
210 1539
220 1574
230 1610
240 1645
250 1679
260 1715
270 1750
280 1787
290 1822
300 1857
310 1892
320 1923
330 1956
340 1988
350 1988
360 2022
370 2060

490 2380
500 2380
510 2418
520 2418
530 2451
540 2480
550 2493
560 2531
570 2566
It took 570 seconds (just over 9 1/2 minutes to return 2566 rows).
The minute breakdown during my trial is as follows:
1 = 655 (+ 655)
2 = 1081 (+ 426)
3 = 1325 (+244)
4 = 1610 (+285)
5 = 1822 (+212)
6 = 1988 (+166)
7 = 2160 (+172)
8 = 2308 (+148)
9 = 2451 (+143)
As you can tell, except for a few discrepancies to the resulting row count at minutes 4 and 7 (I will attribute these to timing as the results grid in SQL Management Studio was being updated once every 5 seconds or so), as time went on, fewer and fewer rows were being returned in a given time period. This was a "successful" run as the entire rowset was returned but on more than several occasions, we have reached the limit and have had 0 new rows per minute towards the end of execution.
Allow me to explain the code in further detail:
[SqlFunction(FillRowMethodName = "FillListItem")]
public static IEnumerable DiscoverListItems(...)
{
ArrayList listItems = new ArrayList();
SPToSQLService service = new SPToSQLService();
[...]
DataSet itemQueryResult = service.DoItemQuery(...); // This is a synchronous call returning a DataSet from the Web Service
//Load the DS to the ArrayList
return listItems;
}
public static void FillListItem(object obj, out string col1, out string col2, out string col3, ...)
{
ArrayList item = (ArrayList) obj;
col1 = item.Count > 0 ? (string) item[0] : "";
col2 = item.Count > 0 ? (string) item[1] : "";
col3 = item.Count > 0 ? (string) item[2] : "";
[...]
}
As you will notice, the web service is called, and the DataSet is loaded to an ArrayList object (containing ArrayList objects), before the main ArrayList is returned by the UDF method. There are 237 rows returned within 10 seconds, which leads me to believe that all of this has occured within 10 seconds. The method GetListItems has executed completely and the ArrayList is now being iterated through by the code calling the FillListItem method. I believe that this code is causing the result set to be returned at a decreasing rate. I know that the GetListItems code is only being executed once and that the WebService is only being called once.
Now alot of my larger queries ( > 20 000 rows) have timed out because of this behaviour, and my workaround was to customize my web service to page the data in reasonable chunks and call my UDF's in a loop using T-SQL. This means calling the Web Service up to 50 times per query in order to return the result set.
Surely someone else who has used Table Valued UDFs has come accross this problem. I would appreciate some feedback from someone in the know, as to whether I'm doing something wrong in my code, or how to optimize an SQL Server properly to allow for better performance with CLR functions.
Thanks,
Dragan Radovic

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 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

Hi!
I have a question about creating a user defined type: I'd like to create a table of employee objects which include objects of the type employee_t. I used this structure before in Oracle 9i and would like to know how it can be done with MS SQL Server 2000 or 2005, preferably with Enteprise Manager/Management Studio. Below is an example.
CREATE TYPE employee_t AS OBJECT (
name VARCHAR(10)
jobDesc VARCHAR(15)
...
)
CREATE TABLE Employee of employee_t

Timo

This is part of the codes of a stored procedure:
-- Create tables variables
DECLARE @_tab_PRNumList TABLE(
PRNum udt_PRNum
)
However, it cannot be compiled coz of this error:
Error 2715: Column or parameter #1: Cannot find data type udt_PRNum.
This user-defined data type is created in a user database only.
I tried to created the user-defined type into BOTH tempdb and master but same error.
How can i resolove it?
Or it is impossible to use user-defined datatype for table variable?
In the past,
i use this method:
CREATE TABLE #PRNumList (
PRNum udt_PRNum
)
and cerate udt_PRNum in tempdb only could solve it.
But now i want to use table variable.
It seems NOT work for my situation.
Any idea?

INSERT INTO @TESTTAB SELECT * FROM dbo.UTIL_TABLE_FROM_STRING(@szDelimit)
Note....The stored function returns a table.
Why doesn't this work ?:
SET @TESTTAB = (SELECT * FROM dbo.UTIL_TABLE_FROM_STRING(@szDelimit))
I wonder if I need to establish a user-defined table type ?I really just want a pointer to the table, and not to have to create a new copy.

I've got a user defined table type called StringDictionaryTVP:
CREATE TYPE [dbo].[StringDictionaryTVP] AS TABLE(
[key] [varchar](500) NULL,
[value] [varchar](500) NULL
)
Ideally I would like to be able to have a # of columns and directions in this table like so:
DECLARE @OrderByClause StringDictionaryTVP
INSERT INTO @OrderByClause([key], [value])
values('gender','desc')
INSERT INTO @OrderByClause([key], [value])
values('name','asc')
Since our database can be a bit sizable, I'd also like to use Common Table Expressions so I can page through them fairly easy.So my standard cte is something like this:
DECLARE @PageIndex INT = 0
DECLARE @PageSize INT = 20
;WITH results_cte AS ( SELECT U.*, ROW_NUMBER() over ( ORDER BY name ) RowNum
from Users U)
SELECT * FROM results_cte
WHERE RowNum > @Offset AND RowNum <= @Offset + @PageSize
So where 'ORDER BY name' is I'd like to use the @OrderByClause in some sort of dynamic way. I've tried all kinds of stuff but even something like this doesn't get the actual column name I need
;WITH results_cte AS ( SELECT U.*, ROW_NUMBER() over ( ORDER BY (select top 1 [key] +' '+ [value] from @OrderByClause) ) RowNum
from Users U)
I may be chasing the wrong stick, but outside of dynamic sql, is something like this possible?

Hi all!
I'm trying to use a UDF that returns a table, but I'm not sure of the syntax to invoke it. I've found examples in BOL and on-line like the following:
SELECT * FROM dbo.fn_MyTableFunc( 123.09, 'MyID' )
But I need the input parameter to be obtained from another table. For a very simplistic example, I've got 4 tables (and yes, I know that I can get the results I want for this example without using a UDF, but humor me):
CREATE TABLE tUser (UserID int PRIMARY KEY, UserName varchar(50))
CREATE TABLE tAcctGroup (AcctGroupID int PRIMARY KEY, AcctGroupName varchar(50))
CREATE TABLE tAcct (AcctID int PRIMARY KEY, AcctGroupID int, AcctName varchar(50))
CREATE TABLE tMapUserToGroup (UserID int, AcctGroupID int)
GO
INSERT INTO tUser VALUES (111, 'Me')
INSERT INTO tAcctGroup VALUES (1, 'NY')
INSERT INTO tAcct VALUES (11, 1, 'New York City')
INSERT INTO tAcct VALUES (12, 1, 'Syracuse')
INSERT INTO tAcctGroup VALUES (2, 'GA')
INSERT INTO tAcct VALUES (21, 2, 'Atlanta')
INSERT INTO tAcct VALUES (22, 2, 'Savannah')
INSERT INTO tAcct VALUES (23, 2, 'Augusta')
INSERT INTO tAcctGroup VALUES (3, 'TX')
INSERT INTO tAcct VALUES (31, 3, 'Dallas')
INSERT INTO tAcct VALUES (32, 3, 'Houston')
INSERT INTO tAcct VALUES (33, 3, 'El Paso')
INSERT INTO tAcct VALUES (34, 3, 'San Antonio')
INSERT INTO tAcctGroup VALUES (4, 'CA')
INSERT INTO tAcct VALUES (41, 4, 'Los Angeles')
INSERT INTO tAcct VALUES (42, 4, 'San Francisco')
INSERT INTO tMapUserToGroup VALUES (111,2)
INSERT INTO tMapUserToGroup VALUES (111,4)
GO
CREATE FUNCTION dbo.ufnGetAcctList(@AcctGroupID int) RETURNS @tAcct table (AcctID int, AcctName varchar(50))
AS
BEGIN
INSERT INTO @tAcct
SELECT AcctID, AcctName FROM tAcct WHERE AcctGroupID = @AcctGroupID
RETURN
END
GO
I know that I can do:
SELECT * FROM TestDB.dbo.ufnGetAcctList(4)
But I want the equivalent of:
SELECT AcctID, AcctName FROM tAcct
WHERE AcctGroupID IN (SELECT AcctGroupID FROM tMapUserToGroup WHERE UserID = 111)
Which uses tMapUserToGroup to obtain the AcctGroupID to pass into the function. The results would be:
AcctID AcctName
-----------------------------
21 Atlanta
22 Savannah
23 Augusta
41 Los Angeles
42 San Francisco
Any thoughts?
Thanks in advance for your help.

I have my defined table type created with
CREATE TYPE dbo.MyTableType AS TABLE
(
Name varchar(10) NOT NULL,
ValueDate date NOT NULL,
TenorSize smallint NOT NULL,
TenorUnit char(1) NOT NULL,
Rate float NOT NULL
PRIMARY KEY (Name, ValueDate, TenorSize, TenorUnit)
);
and I would like to create a table of this type. From this answer [URL] .... the suggestion was to try
CREATE TABLE dbo.MyNewTable AS dbo.MyTableType
which produced the following error message in my SQL Server Express 2012:
> Incorrect syntax near the keyword 'OF'.
Is this not supported by SQL Server Express? If so, could I create it some other way, for example using `DECLARE`?

SET NOCOUNT ON;

I want to add "order by Value" to this stored procedure. Like below:
ALTER PROCEDURE [dbo].[MyProcedure]
@List AS dbo.MyUserDefinedTableType READONLY

I am a SSIS novice, and need help to do the following:
Every day a Table is generated by the system of format XR+present Year + present month + present day. My task is pretty simple. I am to devise a SSIS package that will import this table on to a different server.
I have defined the variable as user defined variable. I am also able to specify the variable in OLE db source editor -> Data Access Mode : Table name or view name variable. When I am click the 'Columns' feature, I get the following error
TITLE: Microsoft Visual Studio
------------------------------
Error at Data Flow Task [OLE DB Source [1]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E37.
Error at Data Flow Task [OLE DB Source [1]]: Opening a rowset for "xr+ convert(char(8),getdate(), 112)" failed. Check that the object exists in the database.
------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC02020E8 (Microsoft.SqlServer.DTSPipelineWrap)
------------------------------

In short can any one tell me a correct way of using a table name as variable in
Data Access Mode : Table name or view name variable ?
One other question: can I make use of a dynamic SQL in Execute SQL Task? If yes, how do I write the query
exec( 'select * from ' + @table)
or just
select * from @table
Any suggestions will be appreciated.

I am working with a vendor application called Cisco Unified Attendant Console - it operates on a Windows server with a SQL express database. The CUPs function of the application needs to reference a "contact" field with only the user portion of the contact's email address - generally, the contact's User ID will match the user portion of their email address, however, for this customer it does not (they use the employee number as the User ID and firstname.lastname as user portion of the email address.
Writing a script to accomplish the following:
The dbo.Contact_Properties table of the ATTCFG database has the following fields that we can work with:
Â
- First_Name
 - Last_Name
 - Email
 - User_Field_2
 - Contact_Unique_Ref (appears to be the field that ties all other contact tables together ?)
Is it possible to create a script that could run daily to either, combine the First_Name and Last_Name fields (with a period between) and populate the User_Field_2 field for each user, or populate the User_Field_2 field with everything before the @ symbol in the Email field for each user?
Also, by default the servers that this application is installed on does not have SQL Server Management Studio installed - is it possible to accomplish with PowerShell script triggered from the Windows Scheduler?

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.

Hi everyone,
I am tring to pass acomma delimited string to a function and this function is parsing the string so that I can see individual values so for example I am passing 1,2,3,4,5 as a parameter to my function and I am parsing this string so that I can write something like this
Select * from tableA where userID in(1,2,3,4)
It is working fine. Only problem is if the user passes word 'all' instead of 1,2,3,4 then I have to doSelect * from tableA
My function looks like this. How can I modify this function if I pass 'all' as a paramater. Any help will be appreciated.CREATE FUNCTION [dbo].[ParseText2File] (@p_text varchar(4000), @p_Delimeter char(1))
RETURNS @results TABLE (id varchar(100))
AS
BEGIN
declare @i1 varchar(200)
declare @i2 varchar(200)
declare @tempResults Table (id varchar(100))
while len(@p_text) > 0 and charindex
(@p_Delimeter, @p_text) <> 0
begin
select @i1 = left(@p_text, charindex(@p_Delimeter, @p_text) - 1)
insert @tempResults select @i1
select @p_text = right(@p_text, len(@p_text) - charindex(@p_Delimeter,@p_text))
end
insert @tempResults select @p_text
insert @results
select *
from @tempResults
return
END
Thanks

How can I create a user defined function in SQL and call it inline from a SQL statement? I need the ability to execute a statement such as:
select myFunc(x,y) from table
I need myFunc(x,y) to return a value, not a recordset and use that value in the select statement. Any and all ideas would be appreciated.

Dear friends,
I am a new user for SQL server. Coming from an oracle background, I find it very difficult to live without user defined functions. At the moment, I urgently need to have a function returning an custom-made ID string, so that it can be used in one of my stored procedures. I have heard the rumours that SQL server 7 does NOT support user defined functions, (which SQL 6.5 does). I would be really grateful if anyone can clarify this for me, and if possible, suggest a get-around approach.
Thanks in advance!
Kai

I am trying to compare the data from one table (shipments) with the data from a view. The point of the function is to match the correct territory with the account depending on the data. Basically, I this deals with accounts that are transfering from one territory to another. The transfers take effect on the first day of the month, retroactive, therefore we need to allocate the sales data to the correct territory in the shipments table. Here is my function. Can someone tell me how I can get this to work and insert a territory ID for the account that has transfered into the shipments table?
CREATE FUNCTION fnShipments ()
RETURNS @Shipments TABLE (AccountID CHAR(10), DateInvoice DateTime, DollarShipments Money, TerritoryID CHAR(10))
AS
BEGIN
INSERT @Shipments (AccountID, DateInvoice, DollarShipments, TerritoryID)
SELECT Shipments.AccountID, Shipments.DateInvoice, DollarShipments, ISNULL((SELECT TerritoryID FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND vwAccountTransfers.EffectiveMonth =
(SELECT MIN(EffectiveMonth)
FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND DatePart(m,Shipments.DateInvoice) < vwAccountTransfers.EffectiveMonth)),
(SELECT TerritoryID FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND vwAccountTransfers.EffectiveMonth Is Null )
) AS Territory
FROM Shipments
ORDER BY Shipments.AccountID, Shipments.DateInvoice;
RETURN
END

I need a UDF that will do the following:
User: Will be sending me a datetime e.g '9 Nov 2004 15:00:00'
I want the UDF to do the following for me
Return in hours the difference between what the user has send and now (lets say now = '10 Nov 2004 11:00:00')
So the UDF will return to me 20.
But I dont want 20, I want the UDF to avoid any all hours which are not work related (any time after 16h00
until 8h00 in the morning), so I want this UDF to return 4. That means from '9 Nov 2004 15:00:00' I have calculated
1hr until 16h00 and 3hrs from 8 until 11h00 on '10 Nov 2004 11:00:00'
AGAIN IT MUST NOT CALCULATE WEEKENDS. Lets say '12 Nov 2004 15:00:00' was Friday and now = '15 Nov 2004 11:00:00', I must still
get 4 as a return from UDF
I would also like now to be my getdate(), but it seems like you can't use it in UDF

I create the following UDF just for learning purposes and I cannot seem to get it to return a value.
Stored Procedure
REATE PROCEDURE usp_GetXSection
@fWidth float,
@fHeight float,
@fResult float OUTPUT
AS
BEGIN
set @fResult = [dbo].[XSECTION](@fWidth, @fHeight)
END
GO
Ane the following UDF
CREATE FUNCTION XSECTION
(@Width float, @Height float)
RETURNS float
AS
BEGIN
RETURN (@Width * @Height)
END
I call it using ADO in a c++ application, but all returns empty
Any ideas? C++ code to follow.
Mike B
void CFormTemplateSetup::OnCalculate()
{
_CommandPtr pCmd(__uuidof(Command));
_ParameterPtr pWidth(__uuidof(Parameter));
_ParameterPtr pHeight(__uuidof(Parameter));
_ParameterPtr pResult(__uuidof(Parameter));
try
{
pCmd->ActiveConnection = GetDocument()->GetConnection();
pCmd->CommandText = _T("usp_GetXSection");
pCmd->CommandType = adCmdStoredProc;
_variant_t vWidth, vHeight;
vWidth.vt = VT_R4;
vHeight.vt = VT_R4;
vWidth.fltVal = 10;
vHeight.fltVal = 10;
pWidth = pCmd->CreateParameter(_T("@fWidth"), adInteger, adParamInput, sizeof(int), vWidth);
pHeight = pCmd->CreateParameter(_T("@fHeight"), adInteger, adParamInput, sizeof(int), vHeight);
pResult = pCmd->CreateParameter(_T("@fResult"), adDouble, adParamOutput, sizeof(float), vtMissing);
pCmd->Parameters->Append(pWidth);
pCmd->Parameters->Append(pHeight);
pCmd->Parameters->Append(pResult);
_variant_t vResult = pResult->Value;
float fArea = pResult->Value.fltVal;
CString csArea;
csArea.Format("Area = %d", fArea);
::AfxMessageBox(csArea);
}
catch(_com_error& e)
{
::AfxMessageBox(e.Description());
}

I am accustomed to doing most of my function work in Access, but the boss would really like it if I could shedule some cubes to do the stuff that takes forever when you run it live.
To that end, I have an Access function that I call to get a field value for a query. I would like to be able to create an User Defined Function on the SQL server and call that function as a field value in a view. I have searched the forums and have not really found anything that wants to make sense to me as to how to do this.
The access function is as follows:
Public Function BuyerDeltas(IFSDate As Date, PODate As Date) As Long
If IFSDate < (Date + 14) Then
BuyerDeltas = IFSDate - 3 - PODate
ElseIf IFSDate < (Date + 29) Then
BuyerDeltas = IFSDate - 7 - PODate
ElseIf IFSDate > (Date + 28) Then
BuyerDeltas = IFSDate - 10 - PODate
Else
MsgBox "This should not be possible!", vbOKOnly, "Fix It!!!!!!!"
End If
End Function
The view that this is called from contains the IFSDate and PODate fields and I am able to call the function from the access query, but this is completely different than what I have seen in the help files on SQL.
I would love to be able to keep plugging away at doing this myself, but the boss also is pushing me to get it done and he doesn't want me taking forever to do it.
Any direction would be greatly appreciated!

I have created a store procedure in sql server 2005.
At first, it shows up as a normal user defined store procedure in Object explorer.
Recently, I found I could not found the procedure in normal place. But the execution is fine.
Finally I found it stays under system procedure folder.
How this could happen?
