MS SQL Server :: SQL2K SP4 Gives Error 1706 Creating Multi-statement Table-valued Function Names Beginning With &&"sys&&"?

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.

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.

Multi-statement Table-valued Functions
Hello

I am trying to do the following:

1. Create a Multi-statement Table-valued Functions, say mstvF1, with 1 parameter.
2. Then, use it like this: "Select * from table T, mstvF1( T.id )"

It gives me Line 100: Incorrect syntax near 'T', referring to the T of T.id.

If I do
Select * from table T, mstvF1( 5 ), then it works.

Is there any way to do a select from a table T combined with an MSTV function and passing in as a parameter a field from T?

Thanks for any help.

Multi Statement Table-valued UDF Without Declaring Columns?
Hey
I have created a multi-statement
table valued function

alter
function
fn_x(@x int)returns
@tbl table
(
          position int identity primary key,          i
int)
as
begin
insert

@tbl values
(@x)          insert

(@x)          insert
into
@tbl values
(@x)          insert
into
@tbl values
(@x)          returnend

Is it possible skipping the
definition of the table columns (the light blue
part)?I need to return a different
structure based on a parameter.Dropping those lines throws an
error "incorrect syntax near 'as'"
The other solution is declaring
each udf separately as one statement udf.Thanks

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)

Passing Table Names To Table Valued Functions
Hello,
It is possible to write stored procedures which take table names as parameters; is it also possible to do this with table valued functions?

For example, a simple stored procedure is this:

CREATE PROCEDURE SelectTop(@tableName sysname)
AS
BEGIN

Execute('Select top 10 * from ' + @tableName + ';')

END

I want to be able to do the analogous thing with a table valued function (so that I can query the result set, without having to create a temp table). How should I do this (i.e., pass a tablename as an argument to a table valued function)?

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,

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

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.

Performance Of Table-valued Function And Execution Plan
I am using SQL2005 EE with SP1. The server OS is windows 2K3 sp2

I have a table-valued function (E.g. findAllCustomer(Name varchar(100), gender varchar(1)) to join some tables and find out the result set base the the input parameters.

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?

Table-valued Function Run Once For Each Row In A Table Variable.
I have a stored produre. Inside this stored procedure I have table variable with one column. Once the table variable is populated with rows, I would like to pass each value in the table, into a table-valued function. The table-valued function may return any number of rows. I would like all the rows the TVF returns to be returned from the stored procedure as a single result set. I would also like to do this without defining a table variable to hold the results of the table-value function.

Code Snippet

declare @IdTable table
(
EmployeeId nvarchar( 16 ) not null
)
insert into @IdTable
select EmployeeNumber from Employees

/*
I need to run this query for every EmployeeId value in @IdTable and return the results from the stored proc as a single result set.
*/
select * from fn_GetEmployeeById( EmployeeId )

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

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,

Calling CLR Stored Procedure From Within A CLR Table-valued Function Giving Errors
We are trying to create a TVF that executes a CLR Stored Procedure we wrote to use the results from the SP and transform them for the purposes of returning to the user as a table.

Code Snippet

[SqlFunction ( FillRowMethodName = "FillRow",

TableDefinition = "CustomerID nvarchar(MAX)",

SystemDataAccess = SystemDataAccessKind.Read,

DataAccess = DataAccessKind.Read,

IsDeterministic=false)]

public static IEnumerable GetWishlist () {

using (SqlConnection conn = new SqlConnection ( "Context Connection=true" )) {

List<string> myList = new List<string> ();

conn.Open ();

SqlCommand command = conn.CreateCommand ();

command.CommandText = "GetObject";

command.Parameters.AddWithValue ( "@map", "Item" );

command.CommandType = System.Data.CommandType.StoredProcedure;

using ( SqlDataReader reader = command.ExecuteReader ( System.Data.CommandBehavior.SingleRow )) {

if (reader.Read ()) {

myList.Add ( reader[0] as string );

}

}

return (IEnumerable)myList;

}

}

When command.ExecuteReader is called, I am getting an "Object not defined" error. However, the stored procedure can be used in SQL Management Studio just fine.

Code SnippetEXEC GetObject 'Item'

Is there some sorf of trick I am missing?

Thank you!

Ambiguous Column Names In Multi-Table Join
Hi all,A (possibly dumb) question, but I've had no luck finding a definitiveanswer to it. Suppose I have two tables, Employees and Employers, whichboth have a column named "Id":Employees-Id-FirstName-LastName-SSNetc.Employers-Id-Name-Addressetc.and now I perform the following join:SELECT Employees.*, Employers.*FROM Employees LEFT JOIN Employers ON (Employees.Id=Employers.Id)The result-set will contain two "Id" columns, so SQL Server willdisambiguate them; one column will still be called "Id", while theother will be called "Id1." My question is, how are you supposed toknow which "Id" column belongs to which table? My intuition tells me,and limited testing seems to indicate, that it depends on the order inwhich the table names show up in the query, so that in the aboveexample, "Id" would refer to Employees.Id, while "Id1" would refer toEmployers.Id. Is this order guaranteed?Also, why does SQL Server use such a IMO brain-damaged technique tohandle column name conflicts? In MS Access, it's much morestraightforward; after executing the above query, you can use"Employees.Id" and "Employers.Id" (and more generally,"TableNameOrTableAlias.ColumnName") to refer to the specific "Id"column you want, instead of "Id" and "Id1" -- the"just-tack-on-a-number" strategy is slightly annoying when dealing withcomplex queries.--Mike S

IIF And Multi-valued Parameters
Hi

i have a report that can show upto 8 charts, dependant on the selection(s) made in a multi-valued parameter.

basically, the report gets loads of data back from DataCube.

if the user has selected (for example) 2 categories in the multi-valued parameter (e.g. "beverages" & "confectionary") , the the first chart will show the results filtered for "beverages" and the second chart will show the results for the "confectionary" category.

but

i want to hide any charts that are not used - i.e. the user only selects 3 categories, i want to show 3 and hide 5 charts and am trying to do this with IIF in the FILTER properties of the chart

so for each chart, i am checking to see if a Category selection has been made for that chart - and if it has, filter the results and display the chart. if no selection has been made, then filter the results for "XXXXX" (no data with this category)

am doing this by trying to get the selected value or "xxxxx" if noting selected

to hide the second chart when only one category has been selected, tried

e.g. for the third chart

=iif(

Parameters!LOOKUPITEMCategoryDescription.count>2,

Parameters!LOOKUPITEMCategoryDescription.Label(2),

"xxxxx")

doesnt work - gives an #Error as a reult

But it works fine when there are > 2 categories selected

also

this works fine when there is 2 or >2 category selected

=iif(

Parameters!LOOKUPITEMCategoryDescription.count>2,

"more than 2",

"not more than 2")

it would appear that IIF is trying to evaluate the TRUE condition(Parameters!HydraCORELOOKUPITEMCategoryDescription.Label(2)) even though the condition is false !!!

help please

thx

GO

I get
Msg 137, Level 15, State 2, Procedure MakeArDetail, Line 43

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.

Problem With Multi-valued Parameters Since SP1
Hi,

after the installation of SP1 I have a problem with multi-valued report parameters.
The option to select all values are gone.
Is there a bug within SP1?

Before the installtion of SP1 multi-valued report parameters works fine, the option to select all values was added automatically within the preview in Visual Studio 2005 and in published reports on the server.

The server was migrated from SQL2000 SP4 to SQL2005.

Displaying Multi-valued Parameters
Hi There.

I am struggling with an issue with multi-valued parameters. I have a parameter that is a list of several hundred items and when someone selects all of them, I display the huge list in the report header vias the join command.

This works great for a few parameters, but overwrites my data when the list is large. I want to do something in the expression where I determine if all items are selected and then just display 'All' instead of the whole list. Any ideas would be very helpful!

Charts And Multi-valued Parameters
I am creating a Line chart report from a table. The source table includes a code column (String), date column (Datetime), and 12 statistic columns (Int). The dates are end of month dates only. ("1/31/2006", "2/28/2006","3/31/2006", etc.) There are about 8 different codes for each month. The statisic columns are the totals for the month for each code for a particular statistic.

PeriodEndDate Code Statistic1 Statistic2 Statistic3 Statistic4 ...
XX/XX/XXXX XX 999 999 999 999 ...

On my line chart I want to show one or more statistics for one year for one or more codes. (A line for each statistic for a given code) The report has multi-valued parameters for the codes and the statistics. I have figured out how to create the chart for one or more codes for a given statistic. How can I select one or more statistic? Can any one help me out?

Setting Defaults On A Multi-valued Parameter
I want to set defaults for my multi-valued report parameter MONTH so that when the report starts, it automatically selects all the months prior to the current month (effectively creates a YTD report). However, using RS2005, I can't seem to figure out how to do this. I can create an IIF expression in 12 different value entries in the report parameters that returns the month based on the system date, but the first time I pass blanks, null or anything except a valid parameter, it clears the entire parameter list when the report displays.

Does anyone have any suggestions for auto-populating multiple values in a parameter at runtime where one or more of the parameter values may be empty? Checking "Allow Null" or "Allow Blank" doesn't fix this problem.

I tried to pass all the values in a single value entry on the report parameters page, but can't find the syntax that will allow this. I'm not sure if it will let you do that anyway...

Passing Multi-Valued Parameter To Subreport
I have a multi-valued parameter that I want to pass to a subreport. The values are 11, 12, 13, and 14.

So here's what I've done:

1. For the properties of the clickable field of the first report, I have gone to the Navigation tab and chosen the subreport in the "jump to report" pulldown.

2. Then I clicked on the Parameters button and added a parameter name for the multi-valued parameter I am trying to send. For the Parameter value, I have tried 11,12,13,14. I have also tried =Split(11,12,13,14)

3. On the subreport, I create a report parameter with the same name, data type is string, multi-value is checked, and the available values pulldown is populated by a query.

So I run the first report and click on the link that brings me to the subreport, but all the subreport shows is the results for 11, not 12, 13, and 14.

How can I get the second report to understand that I want it to show all the records related to 11, 12, 13, and 14? If I bypass the first report and simply use the drop-down to choose 11, 12, 13, and 14 in the subreport, it works fine. I just can't seem to figure out how to correctly have the first report tell the subreport that it wants 11, 12, 13, and 14.

Thanks in advance for any advice!

Dan
