returns varchar(8000)
as
begin
declare @r varchar(8000)
declare @b1 varchar(1000)
set @r = ''
declare c cursor for
select Notes from heatdb..Accs where ID = @a1

open c

fetch next from c into @b1
while @@FETCH_STATUS = 0
begin
set @r = @r + ' ' + @b1

Using And Creating Functions

Aug 10, 2006

I have some code below which is a function in an Access database, the function is a field in a query which find the initial non numeric charceters from a postcode (eg CV8 6UJ returns CV) then returns the region manager. So findPCR("CV8 6UJ") = "Bob Thomas".

I have a view in SQL Server and I want to the exact same thing (create a new field for the view which has as its source the findPCR() function.

So firstly i)can i do this in SQL Server and ii) how do I go about doing it?


Function findPCR(pcode As String)

Dim startpos As Integer
Dim CurChar, sstring As String

startpos = 1
CurChar = "a"

Do While Not IsNumeric(CurChar) And startpos <= Len(pcode)
CurChar = Mid(pcode, startpos, 1)
startpos = startpos + 1
Loop

sstring = "%" & Mid(pcode, 1, startpos - 2) & "%"

If InStr(1, "%B%CV%DE%DY%LE%LN%NG%NN%PE%ST%SY%TF%WR%WS%WV%", sstring) > 0 Then
findPCR = "Bob Thomas"
Else
findPCR = "Unknown"
End If

End Function

Creating Functions

Sep 26, 2007

Hi,
Below is my scenario:
Table name: "Items"
Columns:
Item Id,
Item name,
Item Description

I am implementing a search feature.There is SP for the same.
The item Id is passed as a parameter and the records are fetched.
If the Item id is passed as a integer value all works fine.
For eg. @ItemId=1.
Now the user would like to enter rangevalues on the front end screen.
Like for eg.Item Id = 1-10 or user can enter Item Id=1-10 , 20-25, 30-50
In such a case i am passing the contents as it is.
I.e my @ItemId='1-10 , 20-25, 30-50'
Now i need a function will will decode these appropriately and will return the result for these group of items.

Kindly give me some directions in how to go about this scenario.
Thanks
Renu

Well, I just downloaded SQL 2005 Express to have a play. Good old Billsays "up and running in 20 minutes"Well 5 hrs, 5 reboots and 4 full un-install and re-install later I havefinally got it working. About what I expected really.Anyway, my question relates to creating user defined functions. I've 10yrs exp in MS Access and VB, and user ent Manager to create views onthe work server, but havnt done much with functions.I'm using the Management Studio Express.I've opened a new view and copied the following sample code but it wontlet me save it.-------------------------IF OBJECT_ID(N'dbo.GetWeekDay', N'FN') IS NOT NULLDROP FUNCTION dbo.GetWeekDay;GOCREATE FUNCTION dbo.GetWeekDay -- function name(@Date datetime) -- input parameter name and datatypeRETURNS int -- return parameter data typeASBEGIN -- begin body definitionRETURN DATEPART (weekday, @Date) -- action performedEND;GO------------------------------------------When I try to save it it says"incorrect syntax near the key work 'IF'incorrect syntax near 'GO'CREATE FUNCTION must be the first statement in a query batchmust declair the scalar variable "@Date"Whats wrong with the syntax???Thanks in advanceGrant

Creating A Group By Without Functions -- Possible?

Jul 23, 2005

Hi all,I'm trying to create a layout of our website for Marketing to review,and though I know how I want it presented, I'm not sure how to writethe SQL code to make it work. Here's a sample of the View I've writtenwith all our content:Level Title ID ParentID1 Clinics 11 Services 22 Surgery 1 22 ER 2 22 Radiology 3 22 Clinic 1 4 12 Clinic 2 5 12 Clinic 3 6 13 Heart 1 13 Lung 2 13 Physicians 3 43 Physicians 4 53 Physicians 5 6And the output would basically be this:Clinics- Clinic 1-- Physicians- Clinic 2-- Physicians- Clinic 3-- PhysiciansServices- Surgery-- Heart-- Lung- ER- RadilogyIs there anyway to do this in a SQL statement, or maybe Crystal orAccess? I even tried a Pivot table in Excel, but it wants to sumstuff, and I'm not working with numbers (sums, counts, etc). Alsosince I'm not using any aggrate functions MS SQL is complaining when iuse Group By.Thanks for any suggestions. Also though the layout is similar, theitems listed above are pulled outta the air. Hopefully I typed upsomething that makes since :)Alex

Data Access By Creating Functions

Mar 5, 2006

a number of time I have come accross developers using functions like

GetProduct()
GetProductTitle()
GetProductCategory()

to get the value of the data instead of just using queries / stored procedures

I have not understood why

can you please point to some good forum messages / blogposts / articles on this ?

Whats your take on this ?

.NET Framework :: Error In Creating CLR Functions Saying Server Is Information Protection Configured

Aug 17, 2011

We have few C# binaries that contains definition of CLR functions, and one stored procedure to install / create them in our database. Recently when dropping and recreating the CLR function using our stored procedure, it failed with below error:

Error/info returned: [Microsoft][ODBC SQL Server Driver][SQL Server]This server is Information Protection configured. Only the sql server web application can be used for this function. ([URL])[Microsoft][ODBC SQL Server Driver][SQL Server]The transaction ended in the trigger. The batch has been aborted.

Basically our stored procedure has standard steps to create asymmetric key for each of our C# binary and create login for that key and then grant unsafe assembly permissions to those logins.

It sets show advanced options, clr enabled, and ole automation procedures options. It then using create assembly (for each c# binary with permission_set = unsafe) and create function constructs to create clr functions in SQL server.

SQL Server 2005: CLR Functions Vs SQL Functions

May 26, 2006

I was playing around with the new SQL 2005 CLR functionality andremembered this discussion that I had with Erland Sommarskog concerningperformance of scalar UDFs some time ago (See "Calling sp_oa* infunction" in this newsgroup). In that discussion, Erland made thefollowing comment about UDFs in SQL 2005:[color=blue][color=green]>>The good news is that in SQL 2005, Microsoft has addressed several of[/color][/color]these issues, and the cost of a UDF is not as severe there. In fact fora complex expression, a UDF in written a CLR language may be fasterthanthe corresponding expression using built-in T-SQL functions.<<I thought the I would put this to the test using some of the same SQLas before, but adding a simple scalar CLR UDF into the mix. The testinvolved querying a simple table with about 300,000 rows. Thescenarios are as follows:(A) Use a simple CASE function to calculate a column(B) Use a simple CASE function to calculate a column and as a criterionin the WHERE clause(C) Use a scalar UDF to calculate a column(D) Use a scalar UDF to calculate a column and as a criterion in theWHERE clause(E) Use a scalar CLR UDF to calculate a column(F) Use a scalar CLR UDF to calculate a column and as a criterion inthe WHERE clauseA sample of the results is as follows (time in milliseconds):(295310 row(s) affected)A: 1563(150003 row(s) affected)B: 906(295310 row(s) affected)C: 2703(150003 row(s) affected)D: 2533(295310 row(s) affected)E: 2060(150003 row(s) affected)F: 2190The scalar CLR UDF function was significantly faster than the classicscalar UDF, even for this very simple function. Perhaps a more complexfunction would have shown even a greater difference. Based on this, Imust conclude that Erland was right. Of course, it's still faster tostick with basic built-in functions like CASE.In another test, I decided to run some queries to compare built-inaggregates vs. a couple of simple CLR aggregates as follows:(G) Calculate averages by group using the built-in AVG aggregate(H) Calculate averages by group using a CLR aggregate that similatesthe built-in AVG aggregate(I) Calculate a "trimmed" average by group (average excluding highestand lowest values) using built-in aggregates(J) Calculate a "trimmed" average by group using a CLR aggregatespecially designed for this purposeA sample of the results is as follows (time in milliseconds):(59 row(s) affected)G: 313(59 row(s) affected)H: 890(59 row(s) affected)I: 216(59 row(s) affected)J: 846It seems that the CLR aggregates came with a significant performancepenalty over the built-in aggregates. Perhaps they would pay off if Iwere attempting a very complex type of aggregation. However, at thispoint I'm going to shy away from using these unless I can't find a wayto do the calculation with standard SQL.In a way, I'm happy that basic SQL still seems to be the fastest way toget things done.

Functions?

WIthin SQL Server 2005, there are functions.  This feature is new to me and I haven't found anyone that has written their own fucntions?  I'm wondering if functions are written the same as stored procedures, and can a function be called from a stored procedure or even from within a query.

First/Last Functions In SQL?

Mar 12, 2007

hello Im having a difficult time translating this query from Access to SQL because it uses the First/Last functions.

I have a 'Projects' Table and a 'Project_Comments' table, each has a 'Project_ID' field which links the 2 together. What I need to do is retrieve a Project List from the Projects Table and also the first Comment of each project based on the Commend_date field in the Project_Comments table. This is the MS ACCESS query:


SELECT Projects.Project_Number, Projects.Project_Name, First(Project Comments.Comment_Date), First(Project_Comments.Notes)
FROM Projects Left Join Projec_Comments ON
Projects.Project_Number = Project_Comments.Project_Number
GROUP BY Projects.Project_Number, Projects.Project_Name


Now I can use Min() for the Date instead of First, however I dont know what to do with the Notes field. Any help on how to get this over to sql would be greatly appreciated!

Functions Help

Jun 3, 2008

Hi,

I have created a function that returns a comma seperated list of product id's from a table. I need to call this function from a stored procedure to help filter my product results, something like the following:

SET @SQL = 'SELECT dbo.Products.ProductID FROM dbo.Products WHERE dbo.Products.ProductID IN (' + dbo.GetModels('dbo.Products.ProductID', '') + '))'

The problem I am having when executing the above is:

"Conversion failed when converting the varchar value 'dbo.Products.ProductID' to data type int."

Can anyone shed some light on how I can call the function, feeding through the product ID from the row of the select statement I am trying to execute (if this makes sense).

Any help would be great.

SQL Functions

Aug 10, 2007

Hello,

I've created a function that performs modulo. I understand that SQL server 2000 / 2005 uses % for modulo, but we have an application that was written for Oracle. Oracle has a mod(dividend, divisor) function.

As to not rewite the queries, I would like to implement the function below:

the function executes properly but I must prefix it with the dbo schema.

Net: I can execute --- select dbo.mod(9,2) and it returns a 1 just like it should.

but I can not execute --- select mod(9,2) I receive the error "'mod' is not a recognized function name." on SQL 2000 and 2005.


If I can execute select mod(9,2) then I won't need to re-write any queries.

Also, on SQL 2005, I have tried to adjust the default shema, and the execute as clause, but neither helped my cause.

I'm going to try building the function in the CLR, but I think I will be faced with the same problem.

Can someone point me in the right direction?

Thanks

Tom



create function mod
(
@dividend int,
@divisor int
)
RETURNS int
as
begin
declare @mod int
select @mod = @dividend % @divisor
return @mod
end

Hi,

I have to calculate data in function with "EXEC". During runtime I get the Error:

"Only functions and extended stored procedures can be executed from within a function."

I would use a Stored Procedure, but the function is to be called from a view. I don't understand, why that should not be possible. Is there any way to shut that message down or to work around?
btw: Storing all the data in a table, would mean a lot of work, I rather not like to do. ;-)

It works fine with other SQL tools like winsql?

 My question is, can you call SQL function the way you call stored procedure from ADO .net.  I coded it this way and does not seems to be getting result set back.  The DataReader is seems to be coming back with nothing.  Can someone post an example.  I know you can write "SELECT udf_function()" but I really mean the way the stored procedure is called.  Thanks.

I already declare the parameter which is szSalesmanID. There's a function called AddQStrWhere which can make the query more dynamic. But the thing is when I wanna use the parameter it seems the code doesn't take it, it just use the regular query I dont know why.I already use the function but it just wont work, can you guys tell me what's wrong, Please I really do need some help from you guys, feelin; a lil' bit desperate in here.I appreciate any kinds of help, thanks. FYI: I use Visual Studio.NET 2003, SQL Server 2000.Best Regards.

I have a table that is used for employee evaluations.  There are six questions that are scored either 1, 2, 3, 4, or 5.  I want to tally the responses on a page, but I wonder if I can do it without 35 separate calls to the database (I also want to get the average response for each question).  I know I can do  "SELECT  COUNT(intWorkQuality) AS Qual1 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '1' " and then "SELECT  COUNT(intWorkQuality) AS Qual2 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '2' " and so on.  But can I somehow do the aggregating at the page level, and just refer back to a datasource that uses a generic statement like "SELECT intWorkQuality, intDepend, intAnalyze, intWrite, intOral, intCompatibility FROM dbo.Summer_Project_Req"?  If I can, I am not sure what type of control would be best to use or what syntax to use to write the code-behind. I would like the results to be displayed in a grid format. Thanks in advance for your help.

Using Functions In Openquery

Jul 20, 2001

I'm trying to use the date() function in an openquery statement in query analyzer and I keep getting an illegal symbol ")" error. The statement is :

select *
from openquery([Big Blue], 'select cde_date, cde_item from acch1 where cde_date < date()')

The objective is to find records where cde_date is prior to today. The syntax works fine if I execute it on the mainframe in QMF and the ODBC connection works fine if I hard code the value. What I need is the ability to use the function so I can run the query on subsequent days without having to edit it.

Any suggestions??

Need Help On SQL Server Functions

Sep 6, 2001

Hello all,

Recently I changed over a ASP script from our old Access 97 database to our new SQL database. When I changed it over, some of my SQL pulls on my Active Server Page started to give me erros. One of them is the function
date(). When I used it pulling from Access like this :

strSQLQ = "SELECT * FROM cocoitem WHERE CustNum = '" & strcustnum & "' AND stat = 'C' AND [due-date] > DateAdd('yyyy', -1, Date()) Order By [cust-po], [due-date] ASC ;"

Then it worked fine. When I redirected the ASP to the new SQL server I recieved an error like this:

Microsoft OLE DB Provider for SQL Server error '80040e14'

'Date' is not a recognized function name.

/scripts/order/shippingstatsclose.asp, line 45


So my question is, what is the SQL server equivalent of the function Date()?

STRING Functions

Jul 18, 2000

I have a challenge and am not very versed with coding this situation. The situation is breaking up an address into separate portions: number, number suffix, direction, street name, thoroughfare, street suffix, etc. I am having troubles getting started, could anyone point me somewhere in the right direction with a little guidance or has anyone done this and have the code stored? This is not my strong point and have been trying to improve, sorry. D--

Stored Functions

Oct 20, 1999

Does anyone know how to call a stored procedure from within a SELECT statement? I know sybase has stored functions, but can not figure this out in SQL 7.0.

Example:
Select A.ID, sp_Amount(A.ID,1) as 'Late Fees', sp_Amount(A.ID,2) as 'Payments' from A

I want the ability to return the "amounts" as columns, but without having to go through the hassle of dealing with temp tables or cursors.

Extending Functions In SQL 7.0?

Jun 18, 1999

Is there a way to add functions to SQL (other than stored proceedures) to emulate functions in other systems?

I would like to create a FOXPRO type OCCURS function:

Select * FROM Table1 WHERE OCCURS('Y', FLAGS) > 3

If FLAGS is a VARCHAR(7) and equals "YYYYNNN" then OCCURS would return 4 and the row would return. The database that I am

accessing has >165,000,000 rows and >500 columns per row so you see that I need all the speed I can get!


'
' This is a VB function which works.
' Can this be compiled into a DLL and
' somehow made available to SQL?
'
Public Function OCCURS(expr1 As String, expr2 As String) As Integer
Dim i As Integer
Dim count As Integer
For i = 1 To Len(expr2)
count = count + Abs((Mid(expr2, i, 1) = expr1))
Next
OCCURS = count
End Function

Greatest And Least Functions

Mar 2, 2001

1.I am trying to write following query in SQLserver(this is oracle query),
IS their any equivalent for GREATEST and LEAST functions in SQLServer ???

Update mwebtemp
Set Temp_amount1 = (SELECT SUM(AuthAttr_Amount*(num_Business_Days
(GREATEST(AuthAttr_Start_Date, @dtstartdate),
LEAST(AuthAttr_Finish_Date, @dtenddate))))
.....where...
etc...
.....

Note: this is part of a stored procedure...

2. Also how do you write and call a function in SQLServer (syntax ??), eg.num_Business_Days
is a function returning number of business days between the 2 dates....

thanks a lot

Date Functions

Oct 28, 1999

I have a table of sales transactions that I'd like to group by date, but this is a datetime field so it groups by the date and time, and so it returns more records that I want. Is there an easier way to do this other than using the datepart function to build a date? How can I just look at only the date of a datetime field?
