Can A Stored Procedure Called From An Inline Table-Valued Function
Hi,
I'm trying to call a Stored Procedure from a Inline Table-Valued Function. Is it possible? If so can someone please tell me how? And also I would like to call this function from a view. Can it be possible? Any help is highly appreciated. Thanks

Inline Table-valued Function With Multi-value Parameter
Hello everybody, I need to create a function which takes a multi-value parameter. When I select more than one item, I get the error that I have too many arguments. Does anybody have a solution? Or can I create a view and then do a "SELECT * FROM viewName WHERE columnName IN (@param)"? Thanks in advance for your answers.

How Can I Assign Data Returned From A Stored Procedure Into The Return Table Of A Table Valued Function
Here is the scenario, I have 2 stored procedures, SP1 and SP2 SP1 has the following code: declare @tmp as varchar(300) set @tmp = 'SELECT * FROM OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'', ''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )' EXEC (@tmp) SP2 has the following code: SELECT * FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this) Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used. Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used. Functions - My last resort is to use a table valued function as shown: FUNCTION MyFunction ( ) RETURNS @retTable ( @Field1 int, @Field2 varchar(50) ) AS BEGIN -- the problem here is that I need to call SP1 and assign it's resulting data into the -- @retTable variable -- this statement is incorrect, but it's meaning is my goal INSERT @retTableSELECT *FROM SP1 RETURN END

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't... I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it. So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need. Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like: DECLARE @table table@table=EXEC sp_pkeys MyTable That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great. Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out... SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT) Syntax Error. Ugh. Eventually, I even try: SELECT *FROM Split(substring('abc,def',2,6),DEFAULT) Syntax Error. Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function? SELECT *FROM Split('bc,def',DEFAULT) works just fine. So my questions are: Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it? Is there any way to pass a scalar-valued function as a parameter into a table-valued function? Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround: DECLARE @tmp varchar(8000) SET @tmp=(SELECT dbo.fn_pkeys('MyTable')) SELECT * FROM Split(@tmp,DEFAULT)

Problem With Stored Procedure And Table-valued Functions
Hello Gurus, I have a stored procedure that gathers data from three tables and joins them, two of the tables need to have different rowcounts set, ie. pull only a certain number of rows from one table and only a certain number of rows from another table... The number of rows it should pull are stored within a table for each. Let me explain.... these tables hold Exchange storage group and mailstore data for a number of servers. Each server has a table entry with the number of child storage groups and each storage group has a table entry with the number of child mailstores. The tables get updated every two minutes via a program. I need to be able to get the most Data with the correct child counts for each server and storage group. I believe that i've found a way to do this with a stored procedure that calls a table-valued function. The table-valued function simply filters down the storage group table to it's number of storage groups, ordered by timestamp. I may be way off here, but i can't tell because both the stored procedure and function check out fine but when i execute the stored procedure it gives me the following error: Cannot find either column "dbo" or the user-defined function or aggregate "dbo.GetExchSGInfo", or the name is ambiguous. My code is below: Stored Procedure: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[GetExchangeData2] @top INT, @SID INT, @SGCount INT, @ServerName VARCHAR(50) AS Set @SID = (SELECT ServerID FROM dbo.Servers WHERE ServerName = @ServerName) Set @top = (SELECT sum(Children) FROM dbo.ExchangeSG WHERE ServerID = @SID) Set @SGCount = (SELECT SGCount FROM dbo.Servers WHERE ServerID = @SID) SET ROWCOUNT @top SELECT dbo.ExchangeMSData.*, dboExchangeMailStore.*, dbo.GetExchSGInfo(@SID,@SGCount) As ExchangeSG, dbo.Servers.* FROM dbo.Servers INNER JOIN ExchangeSG ON dbo.Servers.ServerID = ExchangeSG.ServerID INNER JOIN dbo.ExchangeMailStore ON ExchangeSG.StorageGroupID = dbo.ExchangeMailStore.StorageGroupID INNER JOIN dbo.ExchangeMSData ON dbo.ExchangeMailStore.MailstoreID = dbo.ExchangeMSData.MailstoreID WHERE (dbo.Servers.ServerName = @ServerName) ORDER BY dbo.ExchangeMSData.[TimeStamp] DESC, dbo.ExchangeSG.[TimeStamp] DESC SET ROWCOUNT 0 And the Function: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE FUNCTION [dbo].[GetExchSGInfo] ( @SID INT, @SGCount INT ) RETURNS TABLE AS RETURN ( SELECT TOP (@SGCount) * FROM dbo.ExchangeSG WHERE ServerID = @SID ORDER BY [TimeStamp] ) Can anyone help me?

How To Join Using A Table-valued Function?
Hi there. I've hit some gap in my SQL fundementals. I'm playing with table-valued functions but I can't figure out how to join those results with another table. I found another way to hit my immediate need with a scalar function, but ultimately I'm going to need to use some approach like this. What am I misunderstanding here? The Given Objects: function Split(stringToSplit, delimiter) returns table (column: token) table Words (column: Words.word) -- table of predefined words table Sentences (column: Sentences.sentence) -- table of sentences; tokens may not be in Words table, etc The Problems: 1) how do I query a set of Sentences and their Tokens? (using Split) 2) how do I join tables Sentences and Words using the Split function? The Attempts: A) select word, sentence, token from Words, Sentences, dbo.Split(sentence, ' ') -- implicitly joins Split result with Sentences? where word = token resulting error: "'sentence' is not a recognized OPTIMIZER LOCK HINTS option." B) select word, sentence from Words, Sentences where word in (select token from dbo.Split(sentence, ' ')) -- correlated subquery? resulting error: "'sentence' is not a recognized OPTIMIZER LOCK HINTS option."

Indexing Table-valued Function?
I am using a multi-statement table-valued function to assemble data from several tables and views for a report. To do this, I INSERT data into the first few columns and then use UPDATEs to put data additional data into each row. Each UPDATE uses a WHERE criteria that identifies a unique row, based on the value of the first few columns. The problem I'm having is that the UPDATEs are taking forever to execute. I believe the reason is that the temporary table that's created for the function is not indexed, so each row update requires a complete search of several columns. In other situations I've been able to define one column as a primary key for the temporary table, but in this situation the primary key would have to consist of four columns, which doesn't seem to be allowed in the table definition for the function. Is there any way to create indexes for the temporary tables that are created for multistatement table-valued functions? I think that would improve the UPDATE performance dramatically. Thanks, Lee Silverman JackRabbit Sports

Table-Valued Function Result Vs. Calculation Table
I need to return a table of values calculated from other tables. I have about 10 reports which will use approx. 6 different table structures. Would it be better performance wise to create a physical table in the database to update while calculating using an identity field to id the stored procedure call, return the data and delete the records. For Example: DataUserID, StrVal1,Strval2,StrVal4,IntVal1,IntVal2,FloatVal1... Or using a table-valued function to return a temp table as the result. I just dont know which overhead is worst, creating a table per function call, or using a defined table then deleting the result set per sp call.

I found the graphic explanation only show 1 icon to represent the function performance. I cannot find any further detail of the function. (E.g. using which index in joinning) If I change the function to stored procedure, I can know whether the T-SQL is using index seek or table scan.

How To Create A Stored Procedure Of This Code (inline Sql In Aspx) ?

Based on what the user has entered to the form fields, the SQL in constructed on the fly. Since this is now inside codebehind file (aspx.cs), I want to get rid of it and move it to an sproc. But the question is how ? Some simple SQL clauses are easy to convert to an sproc but this is causing me lots of issues.

Handling Large Queries In A Table Valued User Defined Function
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 380 2094 390 2094 400 2130 410 2160 420 2209 430 2237 440 2237 450 2274 460 2274 470 2308 480 2342 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

Stored Procedure Using A Declared Variable In Insert Query (inline Or Using EXEC)
Hello, I have a stored procedure where I run an insert statement. I want to knwo if it is possible to do it using a variable for the table name (either in-line or with an EXEC statement without building a string first and executing that string. See examples of what I am talking about in both cases below: I want to be able to do this (with or without the EXEC) : ------------------------------------------------------------------------------------ DECLARE @NewTableNameOut as varchar(100) Set @NewTableNameOut = 'TableToInsertInto' EXEC( Insert Into @NewTableNameOut Select * From tableToSelectFrom ) ------------------------------------------------------------------------------------ I can not do the above because it says I need to declare/set the @NewTableNameOut variable (assuming it is only looking at this for the specific insert statement and not at the variable I set earlier in the stored procedure. I can do it like this by creating a string with the variable built into the string and then executing the string but I want to know if I can do it like I have listed above. ------------------------------------------------------------------------------------ DECLARE @NewTableNameOut as varchar(100) Set @NewTableNameOut = 'TableToInsertInto' EXEC( 'Insert Into ' + @NewTableNameOut + ' ' + 'Select * From tableToSelectFrom' ) ------------------------------------------------------------------------------------ It is not an issue for my simple example above but I have some rather large queries that I am building and I want to run as described above without having to build it into a string. Is this possible at all? If you need more info please let me know.

Stored Procedure Called From Access97
I have a project that uses an Access97 front end to call a SQL 6.5 stored procedure. The stored procedure BCPs orders to a text file and copies it to a particular server. All works fine if I log into my ODBC/SQL connection as "SA" but if I don't, I received errors saying only the owner or system administrator can execute XP_CMDSHELL, etc. I have tried to hard code the SA account in my database connection string but it doesn't help. I am using qdf.execute to execute my SQL string which is qdf.sql = "execute <procedure name>" Any suggestions appreciated. Thanks, -Darin.

Update Stored Procedure Not Working When Called From C#
OK, I have been raking my brains with this and no solution yet. I simply want to update a field in a table given the record Id. When I try the SQL in standalone (no sp) it works and the field gets updated. When I do it by executing the stored procedure from a query window in the Express 2005 manager it works well too. When I use the stored procedure from C# then it does not work: 1. ExecuteNonQuery() always returns -1 2. When retrieving the @RETURN_VALUE parameter I get -2, meaning that the SP did not find a matching record. So, with #1 there is definitely something wrong as I would expect ExecuteNonQuery to return something meaningful and with #2 definitely strange as I am able to execute the same SQL code with those parameters from the manager and get the expected results. Here is my code (some parts left out for brevity):1 int result = 0; 2 if (!String.IsNullOrEmpty(icaoCode)) 3 { 4 icaoCode = icaoCode.Trim().ToUpper(); 5 try 6 { 7 SqlCommand cmd = new SqlCommand(storedProcedureName);(StoredProcedure.ChangeAirportName); 8 cmd.Parameters.Add("@Icao", SqlDbType.Char, 4).Value = newName; 9 cmd.Parameters.Add("@AirportName", SqlDbType.NVarChar, 50).Value = (String.IsNullOrEmpty(newName) ? null : newName); 10 cmd.Parameters.Add("@RETURN_VALUE", SqlDbType.Int).Direction = ParameterDirection.ReturnValue; 11 cmd.Connection = mConnection; // connection has been opened already, not shown here 12 cmd.CommandType = CommandType.StoredProcedure; 13 int retval = cmd.ExecuteNonQuery(); // returns -1 somehow even when RETURN n is != -1 14 result = (int)cmd.Parameters["@RETURN_VALUE"].Value; 15 16 } 17 catch (Exception ex) 18 { 19 result = -1; 20 } 21 } And this is the stored procedure invoked by the code above:1 ALTER PROCEDURE [dbo].[ChangeAirfieldName] 2 -- Add the parameters for the stored procedure here 3 @Id bigint = null,-- Airport Id, OR 4 @Icao char(4) = null,-- ICAO code 5 @AirportName nvarchar(50) 6 AS 7 BEGIN 8 -- SET NOCOUNT ON added to prevent extra result sets from 9 -- interfering with SELECT statements. 10 SET NOCOUNT ON; 11 12 -- Parameter checking 13 IF @Id IS NULL AND @Icao IS NULL 14 BEGIN 15 RETURN -1;-- Did not specify which record to change 16 END 17 -- Get Id if not known given the ICAO code 18 IF @Id IS NULL 19 BEGIN 20 SET @Id = (SELECT [Id] FROM [dbo].[Airports] WHERE [Icao] = @Icao); 21 --PRINT @id 22 IF @Id IS NULL 23 BEGIN 24 RETURN -2;-- No airport found with that ICAO Id 25 END 26 END 27 -- Update record 28 UPDATE [dbo].[Airfields] SET [Name] = @AirportName WHERE [Id] = @Id; 29 RETURN @@ROWCOUNT 30 END As I said when I execute standalone UPDATE works fine, but when approaching it via C# it returns -2 (did not find Id).

How To Check When A Stored Procedure Was Last Called/executed
HiOur SQL server has a lot of stored procedures and we want to get somecleaning up to be done. We want to delete the ones that have been notrun for like 2-3 months. How exactly will i find out which ones todelete. Enterprise manager only seesm to give the "Create Date"How exactly can I find the last called date ! I guess you could write aquery for that ! but how ???P.S I dont want to run a trace for 1 months and see what storedprocedures are not being used.

How To Get The Output Parameter From An Internally Called Stored Procedure???
Hi all,i have a problem and couldnt find anything even close to it. please help me, here is the description of what i m trying to accomplish:I have a trigger that is generating a column value and calling a stored procedure after the value is generated. And this stored procedure is setting this generated value as an output parameter. But my problem is:my asp.net page is only sending an insert parameter to the table with the trigger, trigger is running some code depending on the insert parameter and calling this other stored procedure internally. So basically i m not calling this last stored procedure that sets the output parameter within my web form. How can i get the output parameter in my webform? Everthing is working now, whenever an insert hits the table trigger runs and generates this value and called stored procedure sets it as an output parameter. I can get the output parameter with no problem in query analyzer, so the logic has no problem but i have no idea how this generated output parameter can be passed in my webform since its not initiated there.any help will greately be appreciated, i m sure asp.net and sql server 2000 is powerful and flexible enough to accomplish this but how??-shane

Gettings Warnings Sent From A Stored Procedure Called With Jdbc
When running a stored procedure, how can i retrieve the warnings that are issued within the stored procedure? the code used is below, the jdbc is connecting fine, it is running the stored procedure, but when an error is raised in the stored procedure, it is not coming back into s.getwarnings() warning raised in stored proc with Code Block RAISERROR ('Error', 16, 1)with nowait; there are no results for the stored procedure, I am just wanting to get the warnings Code Block Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); Connection con = DriverManager.getConnection("jdbc:sqlserver://localh...........); CallableStatement s = con.prepareCall("{call procedure_name}"); s.execute(); //running in seprate thread SQLWarning warn = s.getWarnings(); while (m.running) { if(warn == null) { warn = s.getWarnings(); } safeOut(warn); if(warn != null) warn = warn.getNextWarning(); m.wait(100); }the code is not complete, but should show what is happening it is continually outputting null for the warning, though the strored proc is definately raising errors, which is proven by running it in a query window in sql server. it is retreiving warning if the statement is a raiseerror instead of a call to the proc Code Block CallableStatement s = con.prepareCall("RAISERROR ('Error', 1, 1)with nowait;"); this thread is quite related, but doesnt offer a working solution Getting messages sent while JDBC Driver calls stored procedure any help much appreciated, thankyou Simon

Managed Stored Procedure Not Executing When Called Programmatically
I have created a managed stored procedure in C# tha returns rows of data, based on a couple of input parameters. Stored procedure has been registered with SQL server. Using the Dataset designer in VS2005, I added a new query to my table adapter. The query basically executes the stored procedure registered in the database. From the Dataset designer, the query works fine and returns data as expected. However, when I execute the stored procedure within code, using an instance of my table adapter, I get no data. I call my stored procedure using the following statement: DataTable closeRangePOIs = tableAdapter.GetCloseRangePOIs(x1, y1); The stored procedure, GetCloseRangePOIs(), of my table adapter is not being executed. Any tips on what I should be looking for? TIA. Klaus

Identifying Results Sets When Stored Procedure Called Multiple Times
I have a report based on our product names that consists of two parts.Both insert data into a temporary table.1. A single grouped set of results based on all products2. Multiple tables based on individual product names.I am getting data by calling the same stored procedure multipletimes... for the single set of data I use "product like '%'"To get the data for individual products, I am using a cursor to parsethe product list.It's working great except that I have no idea how to identify theresults short of including a column with the product name. While thatis fine, I'm wondering if there is something that is like a header ortitle that I could insert prior to generating the data that would looka little tighter.Thanks in advance-DanielleJoin Bytes!

Differences Between SQL Stored Procedures And Table-valued Functions
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.
