In-Line Table-Valued Function: How To Get The Result Out From The Function?
Hi all,
I executed the following sql script successfuuly:
shcInLineTableFN.sql:
USE pubs
GO
CREATE FUNCTION dbo.AuthorsForState(@cState char(2))
RETURNS TABLE
AS
RETURN (SELECT * FROM Authors WHERE state = @cState)
GO
And the "dbo.AuthorsForState" is in the Table-valued Functions, Programmabilty, pubs Database.
I tried to get the result out of the "dbo.AuthorsForState" by executing the following sql script:
shcInlineTableFNresult.sql:
USE pubs
GO
SELECT * FROM shcInLineTableFN
GO
I got the following error message:
Msg 208, Level 16, State 1, Line 1
Invalid object name 'shcInLineTableFN'.
Please help and advise me how to fix the syntax
"SELECT * FROM shcInLineTableFN"
and get the right table shown in the output.
Thanks in advance,
Scott Chang

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)

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.

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

Multi-statement Table-Valued Function
I'm creating a Multi-statement Table-Valued Function... Is it possible to insert variables into the table? In other words, is it possible to have something like declare @value1 varchar(10) @value2 varchar(10) BEGIN <do some work on value1 and value2> INSERT @returningTable @value1, @value2 instead of BEGIN <do some work on value1 and value2> INSERT @returningTable SELECT col1, col2 from T_SOURCE Here's why I want to insert variables...My function needs to return a table which contains a 'partial' incremental key. I'll go with an example to explain what i have to do Source_table col1 col2 Mike 10 Mike 20 Ben 50 John 15 John 25 John 35 The table that my function needs to create should look like this col1 col2 col3 Mike 10 1 Mike 20 2 Ben 50 1 John 15 1 John 25 2 John 35 3 I thought of creating a cursor and then looping through it generate col3 and save values of other individual columns in variables. But don't know how to use those variables when inserting records into function table. Any other ideas? I'm caoming from Oracle world, I might be having some strange ideas on how to solve this problem. Any help is appreciated. Thank you.

I have created indexes for the related joinning tables. I would like to check the performance of a table-valued function and optimize the indexing columns by the execution plan. 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. I also found the stored procedure version subtree cost is much grether that the table-valued function I would like to know any configureation in management studio can give more inform for the function performance?

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

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

Hi, I'm having trouble with this multi-statement table-valued function: ALTER FUNCTION MakeArDetail ( -- Add the parameters for the function here @dateStart DATETIME, @dateEnd DATETIME ) RETURNS @arDetail TABLE ( Insurer VARCHAR(50), NABP INT DEFAULT 0, Claim MONEY DEFAULT 0, Payment MONEY DEFAULT 0, NumRx CHAR(7), PatientName VARCHAR(50), Paid030 MONEY DEFAULT 0, Paid3160 MONEY DEFAULT 0, Paid6190 MONEY DEFAULT 0, Paid91120 MONEY DEFAULT 0, Paid121 MONEY DEFAULT 0 ) AS BEGIN DECLARE @arTemp TABLE ( Insurer VARCHAR(50), NABP INT DEFAULT 0, Claim MONEY DEFAULT 0, Payment MONEY DEFAULT 0, NumRx CHAR(7), PatientName VARCHAR(50), Paid030 MONEY DEFAULT 0, Paid3160 MONEY DEFAULT 0, Paid6190 MONEY DEFAULT 0, Paid91120 MONEY DEFAULT 0, Paid121 MONEY DEFAULT 0 ) INSERT INTO @arTemp SELECT DISTINCT Insurer,NABP,0,0,NumRx,Patient,0,0,0,0,0 FROM Pims; UPDATE @arTemp SET Claim = (SELECT SUM(Pims.AmtReq) FROM Pims WHERE Pims.Insurer = @arTemp.Insurer AND Pims.NABP = @arTemp.NABP AND Pims.NumRx = @arTemp.NumRx ); INSERT INTO @arDetail SELECT * FROM @arTemp RETURN END GO I get Msg 137, Level 15, State 2, Procedure MakeArDetail, Line 43 Must declare the scalar variable "@arTemp". I don't understand why SQL thinks @arTemp is a scalar variable which has to be declared. If I don't include the UPDATE command the thing works.

SQL2K SP4 Gives Error 1706 Creating Multi-statement Table-valued Function Names Beginning With &&"sys&&"?
Hi all, I've created a number of tables, views, sproc, and functions whose names begin with "sys_", but when I tried to create a multi-statement table-valued function with this type of name, I got: Server: Msg 1706, Level 16, State 2, Procedure sys_tmp, Line 9 System table 'sys_test' was not created, because ad hoc updates to system catalogs are not enabled.

Return NULL From A CLR Scalar-Valued Function
Hi, I have an assembly that contains the following function: Public Class Lookup <SqlFunction()> _ Public Shared Function MyTest() As Integer Return System.Data.SqlTypes.SqlInt64.Null End Function End Class Then in SSMS: CREATE ASSEMBLY IRS_MyTest FROM '\machine empmyAssembly.dll' GO CREATE FUNCTION dbo.MyTest() RETURNS INT AS EXTERNAL NAME IRS_MyTest.[MyClass].MyTest GO when I run: SELECT dbo.MyTest() the following is returned: Msg 6522, Level 16, State 2, Line 1 A .NET Framework error occurred during execution of user defined routine or aggregate 'MyTest': System.Data.SqlTypes.SqlNullValueException: Data is Null. This method or property cannot be called on Null values. System.Data.SqlTypes.SqlNullValueException: at System.Data.SqlTypes.SqlInt64.get_Value() at System.Data.SqlTypes.SqlInt64.op_Explicit(SqlInt64 x) at Informed.DCLG.IRS.SQL.IncidentTransform.Lookup.MyTest() Can anyone please advise on how to return back a null value. Currently, my only other option is to return nothing (actually returns 0) and then wrap this up to convert the value to null - not ideal. Thanks, Jan.

CASE Function Result With Result Expression Values (for IN Keyword)
I am trying to code a WHERE xxxx IN ('aaa','bbb','ccc') requirement but it the return values for the IN keyword changes according to another column, thus the need for a CASE function. WHERE GROUP.GROUP_ID = 2 AND DEPT.DEPT_ID = 'D' AND WORK_TYPE_ID IN ( CASE DEPT_ID WHEN 'D' THEN 'A','B','C' <---- ERROR WHEN 'F' THEN 'C','D ELSE 'A','B','C','D' END ) I kept on getting errors, like Msg 156, Level 15, State 1, Line 44Incorrect syntax near the keyword 'WHERE'. which leads me to assume that the CASE ... WHEN ... THEN statement does not allow mutiple values for result expression. Is there a way to get the SQL above to work or code the same logic in a different manner in just one simple SQL, and not a procedure or T-SQL script.

Calling Scalar Valued Function From SSIS OleDB Command Transformation
Hi There, I need to call a function to calculate a value. This function accepts a varchar parameter and returns a boolean value. I need to call this function for each row in the dataflow task. I thought I would use an oledb command transformation and for some reason if I say.. 'select functioname(?)' as the sqlcommand, it gives me an error message at the design time. In the input/output properties, I have mapped Param_0(external column) to an input column. I get this erro.."syntax error, ermission violation or other non specific error". Can somebiody please suggest me what's wrong with this and how should I deal this. Thanks a lot!!

Index On Result Of Function
I have a table with about 28 million records in it. Each row has an ID (PK), logged (datetime), IP varchar(15) The data grows at about 14 million records per year. I'm going to be running queries on the table that extract the MONTH or YEAR from the logged column. In Foxpro tables I would have created indexes on YEAR(logged) and MONTH(logged) so my queries would run faster. Is this possible/necessary in SQL Server?

How To Return The Result Of An EXEC From A Function
Hi, I am trying to find a way to return the result of an EXEC(*sqlstring*) from a function. I can return the tsql but not the result of an execute. This is my function: ALTER FUNCTION [dbo].[ReturnPickItemValue] ( -- Add the parameters for the function here @TypeID int, @CaseID int ) RETURNS varchar(max) AS BEGIN -- Declare the return variable here DECLARE @RTN varchar(max) IF(SELECT IncludeDates FROM TBL_LU_PICK WHERE PickTypeID = @TypeID) = 1 BEGIN SET @RTN = 'SELECT PickItem I + CASE D.IsStartDateEstimated WHEN 0 THEN CAST(StartDate as varchar) ELSE CAST(dbo.ReturnEstimatedDate(D.IsStartDateEstimated, 0) as varchar) END + CASE D.IsEndDateEstimated WHEN 0 THEN CAST(EndDate as varchar) ELSE CAST(dbo.ReturnEstimatedDate(D.IsEndDateEstimated, 1) as varchar) END FROM TBL_LU_PICK L INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID INNER JOIN TBL_PICK P ON P.PickItemID = I.PickItemID LEFT JOIN TBL_PickDates D ON D.PickID = P.PickID WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + ' AND P.CaseID = ' + CAST(@CaseID as varchar) END ELSE BEGIN SET @RTN= 'SELECT I.PickItem FROM TBL_LU_PICK L INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + ' AND CaseID = ' + CAST(@CaseID as varchar) END RETURN @RTN END Each time I try " RETURN EXEC(@RTN) " or something similar I get an error. I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error. Anyone with any ideas?

Aggregate Function For Select Statement Result?
Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls. currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do. Problem: i need to call an aggregate count on the results of another aggregate function (sum) with a group by. *ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid. thanks, Tom Anderson Software Engineer Custom Business Solutions

Converting Result Of Aggregate Function Calculation To A Double (C#)
I've put a SelectCommand with an aggregate function calculation and AS into a SqlDataSource and was able to display the result of the calculation in an asp:BoundField in a GridView; there was an expression after the AS (not sure what to call it) and that expression apparently took the calculation to the GridView (so far so good). If I write the same SELECT statement in a C# code behind file, is there a way to take the aggregate function calculation and put it into a double variable? Possibly, is the expression after an AS something that I can manipulate into a double variable? My end goal is to insert the result of the calculation into a database. What I have so far with the SelectCommand, the SqlDataSource and the GridView is shown below in case this helps: <asp:GridView class="gridview" ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="lbsgalDataSource"> <Columns> <asp:BoundField DataField="Formulation" HeaderText="Formulation" SortExpression="Formulation" /> <asp:BoundField DataField="lbs" HeaderText="lbs" SortExpression="lbs" /> <asp:BoundField DataField="gal" HeaderText="gallons" SortExpression="gal" /> <asp:BoundField DataField="density" HeaderText="density" SortExpression="density" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="lbsgalDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT a.Formulation, SUM (a.lbs) AS lbs, SUM ((a.lbs)/(b.density)) AS gal, ( ( SUM (a.lbs) ) / ( SUM ((a.lbs)/(b.density)) ) ) AS density FROM Formulations a INNER JOIN Materials b ON a.Material=b.Material WHERE Formulation=@Formulation GROUP BY Formulation"> <selectparameters> <asp:controlparameter controlid="DropDownList1" name="Formulation" propertyname="SelectedValue" type="String" /> </selectparameters> </asp:SqlDataSource>

Passing MS SQL2005 Query Result Into Javascript Function
I'm selecting the last latitude & longitude input from my database to put into the Google maps javascript function. This is how I retrieve the longitude: <asp:SqlDataSource ID="lon" runat="server" ConnectionString="<%$ ConnectionStrings:LocateThis %>" SelectCommand= "SELECT @lon= SELECT [lon] lon FROM [location] WHERE time = (SELECT MAX(time) FROM [location] where year < 2008)"> </asp:SqlDataSource> I wish to input the latitude & longitude into the JAVASCRIPT function (contained in the HTML head before the ASP) something like this: var map = new GMap2(document.getElementById("map"));var lat = <%=lat%>;var lon = <%=lon%>;var center = new GLatLng(lat,lon);map.setCenter(center, 13); However, lat & long do not contain the retrieved result but rather a useless System.something string. How do I assign the retrieved results to these variables and port them over to Javascript as required? Many thanks!
