Jul 14, 2015I am creating mateialized view but it is failing with error that it can't be schema bound.
The query I am working to create materialized view are having joins with different tables and function.
Is it possible to create Indexed views on user defined functions?

Feb 7, 2006User-Defined string Functions MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net)
Ladies and Gentlemen,
I am pleased to offer, free of charge, the following string functions MS SQL Server 2005 Transact-SQL SQLCLR (VB. Net, C#.Net, C++. Net):
AT(): Returns the beginning numeric position of the nth occurrence of a character expression within another character expression, counting from the leftmost character.
RAT(): Returns the numeric position of the last (rightmost) occurrence of a character string within another character string.
OCCURS(): Returns the number of times a character expression occurs within another character expression (including overlaps).
OCCURS2(): Returns the number of times a character expression occurs within another character expression (excluding overlaps).
PADL(): Returns a string from an expression, padded with spaces or characters to a specified length on the left side.
PADR(): Returns a string from an expression, padded with spaces or characters to a specified length on the right side.
PADC(): Returns a string from an expression, padded with spaces or characters to a specified length on the both sides.
CHRTRAN(): Replaces each character in a character expression that matches a character in a second character expression with the corresponding character in a third character expression.
STRTRAN(): Searches a character expression for occurrences of a second character expression, and then replaces each occurrence with a third character expression. Unlike a built-in function Replace, STRTRAN has three additional parameters.
STRFILTER(): Removes all characters from a string except those specified.
GETWORDCOUNT(): Counts the words in a string.
GETWORDNUM(): Returns a specified word from a string.
GETALLWORDS(): Inserts the words from a string into the table.
PROPER(): Returns from a character expression a string capitalized as appropriate for proper names.
RCHARINDEX(): Similar to the Transact-SQL function Charindex, with a Right search.
ARABTOROMAN(): Returns the character Roman numeral equivalent of a specified numeric expression (from 1 to 3999).
ROMANTOARAB(): Returns the number equivalent of a specified character Roman numeral expression (from I to MMMCMXCIX).
AT, PADL, PADR, CHRTRAN, PROPER: Similar to the Oracle functions PL/SQL INSTR, LPAD, RPAD, TRANSLATE, INITCAP.
Plus, there are CHM files in English, French, Spanish, German and Russian.
Plus, there are versions for MS SQL SERVER, SYBASE ASA, DB2, Oracle.
More than 8000 people have already downloaded my functions. I hope you will find them useful as well.

User Defined Functions In SQL Server 7.0
Nov 4, 2004hai,
I have 3 fields in my table say (F1, F2, F3). I want to get the max value out of the three fields for each row. I can create a user-defined function which accepts 3 arguments and then return the max value if i am using SQL Server 2000. But now i am using only SQL Server 7.0 (it does not support user-defined functions :confused: )
So any one could kindly let me know how could i do it in SQL Server 7.0
Thnks in advance

User-defined Functions - Help!
Sep 3, 2004Hi,
I have a search returning many 'car' records (regno, mileage, color, etc)
In a seperate table I have two columns: accessory and regno. This can have many rows for each regnumber.
Within the storedprocedure that returns the 'car' records I need to also return the relevant accessories for that car as one column.
I have written a function as such (with some help!):
ALTER Function getAccs(@regNo varChar(20))
RETURNS varChar
AS
BEGIN
Declare @List varchar(1000)
SELECT @List = COALESCE(@List + ', ', '') + accessory
FROM frxrep2.dbo.usedaccessories WHERE regnumber = @regno
return @List
END
I was hoping that I could simply use this in the 'car' SELECT statement.
ie:
SELECT regNo, color, mileage, dob.getAccs(regno) as AccessoryList
FROM tableBla etc
I'm not even sure if the function works - How can I test in SQL analyzer?
any help much appreciated,
Pete
User Defined Functions In SQL 7.0
Oct 11, 2000Hi,
I know that we cannot have User Defined Functions in SQL 7.0, but is there a work around. I am trying to standardize the date according to the time zone using a function and use it as part of a select statement.
I cannot believe that is not possible in SQL 7.0, can somebody tell me what is the work around, I am running against time. I really appreciate any help on this one.

User Defined Functions And OLE
Aug 18, 2006Hi everyone
I am implementing an encrypted data system whereby captured data is encrypted using MS CAPICOM when written to DB and decrypted when displayed. It works well. However, each time you write the data back on update the encryption is different from the previous time.
I have a search screen that allows users to enter text data and submit it looking for matches. Of course, the user is entering unencrypted text and the DB data is encrypted.
This means that you can't encrypt the input data before you try to match because the encryption alogorithm used on the input data will not match that which was used to encrypt the DB data.
Are you with me so far?
So, you have to compare the uncencrypted input data with DECRYPTED DB data - in other words, decrypt the DB data on the fly within the where clause of your query.
I have accomplished this by writing a UDF that instantiates an instance of the CAPICOM encryption module and calling the UDF when applying the query
eg where udf(columnname1) = 'inputtext' or udf(columnname1) = 'inputtext'.
It works, I get the results that I want.
But, alas, the performance has taken a search severe hit.
Has anyone else ventured down this road?
Is there a better way of doing this?
Thanks
Ray

User Defined Functions
Feb 19, 2004When I define a UDF in SQL 2000 I can't execute it without qualifiction. Here's the code:
CREATE FUNCTION GetLastShipDate(@DO_No CHAR(10))
RETURNS CHAR(10)
-- DROP FUNCTION GetLastShipDate
BEGIN
DECLARE @v_last_ship_date CHAR(10)
SELECT @v_last_ship_date = COALESCE(CONVERT(CHAR(10), MAX(Asn.Asn_Ship_DateTime), 110), '')
FROM Asn,Asn_Do
WHERE Asn_Do.Asn_Number=Asn.Asn_Number
AND Asn_Do.DO_Number = @DO_No
AND Asn.ASN_STATUS in ('SENT','RESENT')
RETURN @v_last_ship_date
END
So I have to execute this with:
SELECT dbo.GetLastShipDate('T010215004')
I want to execute it with
SELECT GetLastShipDate('T010215004')
What am I doing wrong?

Today while using user defined functions, I noticed that we must write dbo. before the function name which I did not conceive why it is used like that. Why are there an exception for functions ?
Why do we not have to use the same thing while using SP or not user defined functions ?

Help With User Defined Functions
Jul 18, 2007Dear all,
I was given a project to transfer our database into sql server database.
In our previous database we used the datatype int4 for some columns to create some views and in some queries that we used to build our datawindows. In SQLServer 2000 i created a user defined function named int4. I can execute it with the line select dbo.int4(poso) from employee .
Unfortrunately this way make me to rebuild all my datawindows and replace int4( with dbo.int4( . Is there any way to execute queries using user defined function but omitting the first part name dbo. I mean to manage execute the command select int4(poso) from employee \let int4 be a user definded function.
If i can€™t solve this, i thing it will decided than is impossible to move to sqlserver Database. Has anyone any suggestions?
Thanks in advance,

Learning About User Defined Functions
May 26, 2006I am getting some trial by fire here as I need to update some user defined functions in an application a co-worker built. He has since left and I've been asked to take over this project since I had a VB 6.0 and regular ASP class 6 years ago ... obviously quite a transition! I have started to figure out a bit but I can't find much on creating my own User Defined Functions and/or the best ways to test ones that I need to edit. My first one came back with this after I added it to SQL Server 2005 through Enterprise Manager... Exception Details: System.Data.SqlClient.SqlException: Invalid object name 'dbo.fn_User_Data'.Thanks for any tips,Andrew
View 1 Replies View RelatedUser Defined Functions And EXEC
Mar 5, 2008I'm using MS SQL Server 2005.
I want to simulate a table, using a Multi-statement Table-Value User-Defined Function, but I need the function build the SQL statement from scratch each time so I can dynamically define values like the table it references. The only way I know how to run the query after it has been defined in this manner is to run an EXEC command. However I'm getting an error basically saying that the EXEC command is off limits in a User Defined Function.
The Exsact Error is:
>[Error] Script lines: 1-108 ------------------------
Invalid use of side-effecting or time-dependent operator in 'EXECUTE STRING' within a function.
Is there some way to get around this limitation of User Defined Functions. Or perhaps a way to simulate the functionality of Multi-statement Table-Value User-Defined Functions in a Store Procedure, specifically the ability to run where statements, or transform the data on the fly without re-writing the Stored Procedure every time.
The code I’m trying to run is below.

User Defined Functions To Stored Procedures
Jun 1, 2004Hello all:
Running into a brain problem here. I remeber reading an article a while back (2002?) on either Visual Studio Magazine or MSDN Magazine where there was a way to generate Stored Procedures from User Defined Functions. I need this information in order to do my job as it is also a way to cut down on time for this project I am trying to finish. Does anyone have the code or remeber what I am talking about. I just finished Kathleen Dollards article again on using XSLT to generate code but would really like to use the User Defined Functions.
I searched for the article on line but came up dry. Searched through all my magazines but could not find the article. Any help would be greatly appreciated. Bit of topic I guess but still relevant to the board.
Thanks

View 4 Replies View RelatedHow To Avoid Using Scalar User Defined Functions
Sep 26, 2015Following the horrendous performance of Scalar UDFs demonstrated in this thread URL....(Scalar UDF 10x slower than writing the code, long hand, in the SELECT) I now have the worry that their widespread usage in my code needs to be refactored. I guess pretty much any single-line non-table-valued scalar-function would do
CREATE FUNCTION dbo.FNSafeString
(
@strValuevarchar(8000),-- STRING Value to convert to SAFE string
@intModeint = 0-- 0=NULL as '[NULL]', 1=NULL as ''
)
RETURNS varchar(8000)
WITH SCHEMABINDING
AS
BEGIN
RETURN COALESCE(@strValue,
CASE WHEN @intMode = 0
THEN '[NULL]'
ELSE ''
END
)
END
Its a little bit too big to really want to have to write it in each place where I need to use it, and its just big enough that it is worth centralising, and it might just be that I could code it more efficiently / different / handle more "edge cases" in the future.I do have even more straightforward UDFs - just to avoid typing something "Lengthy"
CREATE FUNCTION dbo.FNDateMidnight
(
@dtDateTimedatetime-- Date/Time Value to adjust
)
RETURNS datetime
WITH SCHEMABINDING
AS
BEGIN
RETURNDATEADD(Day, DATEDIFF(Day, 0, @dtDateTime)+1, 0)
END
Perhaps I should consider changing them to inline table valued functions, or CROSS APPLY them? but I can't think of a way to centralised them and re-use the code WITHOUT a function, can I?

Computed Fields And User-defined Functions
Apr 13, 2006Hi everyone,
I would like to get some clarification about what these two concepts are.
This is what I think:
lets say that you want the user to choose two columns to add together and then that produces a calculated result. This would go in a computed field???
And user-defined functions are functions whereby users have for example to which which two columns they were going to allow to be processed for the calculation.
Is this correct???

Apr 11, 2006In a typical Database, there are tables, views, stored Procedures, user Defined Functions.
We could use tables and views in designing the Report Model.
We cannot use Stored Procedures, I tried that.
Please could somebody tell me if we could use User Defined Functions?
What if a view is already using a user defined function, is the function automatically includid in the Model Design?
Thank you,
