User-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.

my username is selevalencia, I had before the database on my machine, but as now we have a server I backed up the database and restored on the server, it seems that it has the sames logins and security users,
Its strange because the user dbo is assigned the user selevalencia on the server, and I cant alter the user dbo.
The user dbo should be the login sa?? I am in big trouble with this, beacuase I cant debug my sql clr stored procedure.
T-Sql execution ended without debugging. You may have not have sufficient permissions to debug.
I am using a connection with windows authentication, so it means that its sending tha tokes as selevalencia to the server.
Please feel free to ask for more information about it. Thanks
I developed a search stored proc that searches all orsome of Procs, Views, Triggers and functions. Would anyone be interestedto see it posted here?Do you have any suggestions about other places, websites forums ...., toshare something I have developed?Thanks you for your response in advancePLease send me emailJoin Bytes! {Remove ### before responding}
Hi allTrying to figure out what you use ms sql functions for. I understand stored procedures and how to create them. the question is what is the real purpose of a ms sql function considering everything i have read so far makes me think that there is no valid use for them. You can do almost everything that a function does but in a stored procedure. If somebody can give me a good examplle of a sql function i would appreciate it very much.thanks
I hope I didnt POST in the wrong group. If I did sorry. Anyhoo, on to my question. I have searched the forums and didnt quite find what I was looking for so here goes.. I have create a function that is supposed to return the "SCOPE_IDENTITY" from a stored procedure that updates the database. I'm kinda lost as to how to get the SCOPE_IDENTITY into the function. I have the following line in the function:
Dim retcode As Integer = cmd.Parameters.Add("@retcode", SqlDbType.Int).Direction = ParameterDirection.ReturnValue ... cmd.ExecuteReader(CommandBehavior.CloseConnection)
If I run the stored procedure by itself I get @retcode = 135 @RETURN_VALUE = 135 So i know the stored procedure works but how do I get that return value into a asp.net function?
I have a linked server and I want to execute SQL statements on that linked server which contains millions of records. so I decided to use SELECT * from OPENQUERY(RmtSrv,'SELECT * FROM RmtTbl WHERE Col = ' + @ColValue) but Unforetunatly the query is not succeeded because the OpenQuery doesn't accept parameters.
I used Scalar valued functions and built the query dynamically, but the Scalar valued functions doesn't execute dynamic SQL
ET @LinkedServerName = 'RmtSrv'
SET @RemoteTable= 'RmtTbl'
SET @Query = 'SELECT * FROM OPENQUERY({0}, ''SELECT Col1 FROM {1} WHERE Col2 = ''''{2}'''''') '
SET @Query = REPLACE(@Query, '{0}', @LinkedServerName)
SET @Query = REPLACE(@Query, '{1}', @RemoteTable)
SET @Query = REPLACE(@Query, '{2}', @Col2Value)
EXEC(@Query)
the above code is not executed because the functions doesn't execute dynamic queries.
I deleted the function above and wrote a Stored Procedure with the same code. but I can't query the stored procedure
SELECT GetColValue(Table1.Col1) FROM Table1.
where the GetColValue is the name of the stored procedure.
Do you have any solution that I can use to perform Remote SQL statements considering the performancewise and the code shall be centralized in certain stored procedures and functions
the Remote server contains millions of records and I will use it from tens of applications and databases.
Hi There, I've written an inline table-valued function in SQL such as the following:
ALTER FUNCTION dbo.GetCityByID( @CityID int) RETURNS TABLE AS RETURN( SELECT Name, Url FROM Cities WHERE (CityID = @CityID) )
suppose that Cities table includes three fields (CityID, Name, Url).
By the way I wrote a store procedure as follow:
ALTER PROCEDURE MyProcedure ( @MyID int) AS SELECT CountryID, OriginCityID, DestCityID FROM MyTable WHERE (MyID = @MyID)
The OriginCityID and DestCityID are related to CityID in Cities table. I wanna get the name and url of each city by its ID through this stored procedue by making relation to Cities table. so I call GetCityByID function in my stored procedure like this:
ALTER PROCEDURE MyProcedure ( @MyID int) AS SELECT CountryID, dbo.GetCityByID(OriginCityID), dbo.GetCityByID(DestCityID) FROM MyTable WHERE (MyID = @MyID)
this procedure dosn't work an returns error.
What's your solution for getting information from Cities table for OriginCityID and DestCityID? Thank you in advance.
Novice question. Would someone explain tell me what a view is used for? Also I am confused about the difference between a function and a stored procedure. They both seem like functions to me.

want to check, triggers are executed After the command is done right? not b4 isit? so if i want to check if the entry is to be Inserted, i should use SP instead? either that or i can use ROLLBACK right? how do i use ROLLBACK? finding Google also at the moment
Does anyone know of or have a method for tracking stored procedures that get called by a trigger. I have inherited a project that when a user updates a row in a particular table, triggers get fired and result in a nesting error. Thanks for your help in advance.
Can I have a trigger call a stroed procedure and then in turn have the stored procedure call a COM object? If so how? Or where can I get the info to do it?
I have to write a script that would make prefixes for a word
for ex: Ragini Venkataraman ( is the string) is the record from one table and i need to store prefix "rag" and "ven" as two records in another table.... I need to know if this can be done using just SQL stored procedures or triggers...or if there needs to be some code(java code..we are using language java) written.. any help on how it can be done would be great....iam completely new to sql and it all seems confusing....
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.
Hi everyone.I'd like to know how stored procedures and table-valued functions compare when it comes to returning a resultant set of data. I know there is a link somewhere but I can't immediately find it.Thanks.
WE release our software once a week. In 1 months time we will have over 500 stored procedures in our DataBase. What we do for releases is when a stored procedure is changed, we put the Drop and Create parts of that script in our SQL Update Script. A problem comes up when Developer A changes My_StoredProc and then developer B changes the same stored procedure. Sometimes it works ok (the developer B will run the update script before changing his stored procedure. HOwever, it can happen where one Update script file has the same SP 5 times (5 drops 5 creates)... especially if over 300 SP's are getting updating in 1 release. We will always catch these on our tests, however, it's the 2 hours to fix the Test DB after we run these tests... What is the best way to manage these? We thought about putting our stored procedures into Team Foundation Server, but we don't know if that will work for us. We have 8 developers in our team. If anyone could help or give advice on this, it would be awesome. Thanks.
One advantage that I can see withh UDFs is that they are a bit a Views with parameters. You can perform joins on UDF columns (which you cannot do with a Stored Proc). You can do the same with Views but UDFs have the advantage that you restrict the number of rows with a parameterised WHERE (or HAVING) clause.
I would like to know if the the DLL`s one can build with VB5/6 can be used to construct Extended Stored Procedures in MS SQLServer 6.5? If so, how does one do this. All the reference material I`ve come across is for C

Hi to all, Can any body tell me what is the difference between Stored procedures and User Defined Functions ? In my assumption Function return a value or table, but SP doesn't return value instead of that SP use select statement or assign value to output statement. This is right?
Hi,Right, i have a fairly good understanding of SQL. However, i have a fairly basic understanding of SQL Server.I know Storedprocedures are really good and i'm starting to use them. I understand they are good for making inserting, updating very easy.However when you look at a SQL Server database you get various folder, this leaves me a little confused with what they are all used for? whats the difference between these?Thanks in advance!sorry for the basic question, i'll try to challange you next time
Hi, l've created an function [GSM].[KPIAging], and test it in studio by substitule declare value, i.e. DECLARE @sCellName VARCHAR(8) DECLARE @dDate DATETIME SET @sCellName = "CELL1M_1" SET @dDate = CAST('06/Jun/2006' AS DATETIME)
EXEC GSM.KPIAging @sCellName, 'CSSR', @dDate
It work fine and return the desired result, but when l used this function in SQL, SELECT DATEKEY, CELLREGIONKEY, CELL_NAME, CELL_ID, CSSR, GSM.KPIAging(Cell_Name, 'CSSR', @dDate) FROM GSM.GSMCellDaily_vw WHERE CSSR BETWEEN 0 AND 85 AND FULLDATE = @dDate AND CM_SERV > 30 AND (TCH_TRAFFIC > 2 AND TCH_SEIZURES_ATTS > 30)
I got the following error, i.e. Msg 557, Level 16, State 2, Line 19Only functions and extended stored procedures can be executed from within a function. Does anyone have any idea on this, and what's the workaround for this?
We have recently begun using transactional replication to keep the data in our SQL Servers synchronized in a geographically dispersed environment. We replicate our tables but we have never replicated views, stored procedures, or user functions in our production systems. We are thinking of doing so but wonder if the overhead of running the replication agents doesn't outweigh the benefits of having replication assist with the occassional change to these design elements.
Is anyone on this forum replicating views, sprocs, and user functions? What has your experience been?
I am a bit confused by the difference between a stored procedure and a table-valued function. Can somebody please either give me a simple explanation, or point me at something I can read.
I thought I had it worked out, and had coded some action queries as stored procedures, and I wrote a table-valued function that was effectively an encapsulated SELECT so that SELECT * FROM Spouse(@ID) worked fine. Then I wanted to use a function SpousePair, that was similar to Spouse, to power a Gridview. I discovered that I couldn't. It seems that a SQLDataSource requires either a SELECT statement or a stored procedure. So I wrote a stored procedure SpousePair(@ID1, @ID2).
I find that whereas I tested Spouse with SELECT * FROM SPOUSE(@ID) I tested SpousePair with EXEC SpousePair @ID1 @id2
Now I want to combine these: if I could I would write SELECT * FROM SPOUSE(@ID) WHERE SPOUSEID NOT IN (SELECT SPOUSEID FROM SpousePair(@ID1, @ID2))
However this is invalid because you can't put a stored procedure in a Select statement, and SELECT .... NOT IN (EXEC SpousePair @ID1 @ID2) is also invalid.
Is there any alternative to creating a table-valued function, SpousePairA, that is identical to SpousePair but coded as a function. I'm reluctant to do this because then I'll have two bits of quite complicated SQL logic to maintain.
From the SQL Server documentation : "The input parameters and the type returned from a SVF can be any of the scalar data types supported by SQL Server, except rowversion, text, ntext, image, timestamp, table, or cursor"This is a problem for me. Here's what I'm trying to do :I have an NTEXT field in one of my tables. I want to run regular expressions on this field, and return the results from a stored procedure. Since SQL Server doesn't provide facilities to perform regular expressions, I need to use an SQLCLR function. I would have no problem doing this if my field was nvarchar. However, this field needs to be variable in length - I cannot set an upper bound. This is why I'm using NTEXT and not nvarchar in the first place.Is there a solution to this problem? I can't imagine that I'm the only person who wants to pass strings of arbitrary size to an SQLCLR function.
