upon running executing this function with valid values i am not getting any results.
anything is wrong?
thank you,
I started with an inline table returning function with a hard coded input table name. This works fine, but my boss wants me to generalize the function, to give it in input table parameter. That's where I'm running into problems.
In one forum, someone suggested that an input parameter for a table is possible in 2012, and the example I saw used "sysname" as the parameter type. It didn't like that. I tried "table" for the parameter type. It didn't like that.
The other suggestion was to use dynamic sql, which I assume means I can no longer use an inline function.
This means switching to the multi-line function, which I will if I have to, but those are more tedious.
Any syntax for using the inline function to accomplish this, or am I stuck with multi-line?
A simple example of what I'm trying to do is below:
Create FUNCTION [CSH388102].[fnTest] ( -- Add the parameters for the function here @Source_Tbl sysname ) RETURNS TABLE AS RETURN ( select @Source_Tbl.yr from @Source_Tbl )
Error I get is:
Msg 1087, Level 16, State 1, Procedure fnTest, Line 12 Must declare the table variable "@Source_Tbl".
If I use "table" as the parameter type, it gives me:
Msg 156, Level 15, State 1, Procedure fnTest, Line 4 Incorrect syntax near the keyword 'table'. Msg 137, Level 15, State 2, Procedure fnTest, Line 12 Must declare the scalar variable "@Source_Tbl".
I have to work with some configuration data that is stored in rows as a comma separated values. Something like this:
Key1 A,1,Z,0;B,2,Y,9;C,,8,X;
Key2 Alpha,101;Beta,102;
Each group of data is separated by a semicolon and each value by a comma. The quantity of values may vary from one key to the other. Over this values sometimes I need to run some selects, so I went with the idea to get it as a table using CLR.
There I find the first problem: I didn't find a way to return a "variable" column with a CLR function, I had to create a SP. Ok, now I execute spGetConfigurationAsTable 'Key1' and I can obtain something like this:
A 1 Z 0
B 2 Y 9
C 3 X 8
But I'm faced with a second problem: How can I run a query over this? I didn't find a way to run a query over an output of a SP. And I can't INSERT the result into a temporary table because I cannot CREATE the table static (remember the columns may differ from one configuration to the other).
So, it seemed a pretty simple task and a neat solution, but I'm kinda stuck. Is there a way to run a query over the SP output? Or is there a way to have a variable table output from a CLR UDF?
Here is the code of the CLR SP I use to obtain the data, and also the (non-working) CLR user defined function.
THANKS!

I have a SQL function which returns a varchar(max). This gets truncated when the length is greater than 8000. Could you let me know how do I get the return value in a function without it being truncated.
I have this assignment where i have a table full of two digit exam scores and I have to write a function that eliminate x number of top values and x number of bottom values and return all the middle values. When the function is called, obviously a number is entered such as 3 and the top 3 and bottom 3 scores are not returned. i.e. SELECT * FROM GetMiddleValues (3);
If anyone has any ideas on how to accomplish this, that would be great.

Hi all--I've got a derived column transformation where I am adding a field called Import_Date. I'm telling it to add as a new column and use the function "GetDate()" to populate the field. When I run the package, it returns NULL as the data value for all rows. Any idea why this might be happening?
I have a problem with "timeout expired. Thei timeout periode elapsed prior to obtaining a connection from the pool. This may have occured because all pooled connections were use and max pool size was reached" Then i explore and found out that i did not close my SqlDataReader, SqlDataAdapter, SqlCommand or my connection.
But i have a function that return a SqlDataReader. Is this function will cause a connection problem?
Thanks in advance

I'm trying desparately to write a PadRight function in SQL Server 2005. I seem to be failing miserably because the trailing spaces disappear when the data is returned. First of all, why does SQL Server think I want my string trimmed? And second, how do I overcome this? Code below:
Code Snippet CREATE FUNCTION [dbo].[PadRight] (
@sourceString NVARCHAR(4000), @length INT, @padCharacter NCHAR(1) = ' ', @trimBeforePadding BIT = 1 ) RETURNS NVARCHAR(4000) AS BEGIN
DECLARE @returnStringLength AS INT, @toReturn AS NVARCHAR(4000) SET @toReturn = LEFT(@sourceString, @length)
IF @trimBeforePadding = 1
SET @toReturn = RTRIM(LTRIM(@toReturn)) SET @returnStringLength = LEN(@toReturn) IF @returnStringLength < @length
SET @toReturn = @toReturn + REPLICATE(@padCharacter, @length - @returnStringLength) RETURN @toReturn END GO
I'm running the following test query on a single table:

There's an SP that in effect returns a table -- it loops and executesstatements like SELECT @field1, @Field2, @Field2Can I capture its results in a table? I know that if it were a FUNCTIONthat returned a table, that would be simple:INSERT ResultsTable SELECT * FROM dbo.Function (@Param1, @Param2)But how to do that if the code is a procedure rather than a function?
Hi, I'm new to the forums, so hopefully I'm at the right place with my question...
Suppose I have a user-defined type in C#, which stands for simple point in 2D (let's call it Point). The type consists of two integer fields that represent the X and Y coordinate of the point. To make things a little more complicated, I want to store my values compressed using an algorithm, so I can't directly access X and Y without using a decompression algorithm.
I also have a table (PointTable), it's only column is called Data and is of type Point.
Now, writing and executing a simple query like
SELECT Data.ToString() FROM PointTable is no problem at all.
What I want to do, is to be able to retrieve a table filled with the X and Y coordinates, so something like this:
SELECT PointX, PointY FROM GetTable() where GetTable creates a table with columns PointX and PointY.
The function GetTable() should be implemented in C#, and work something like this: iterate through all Point values, decompress them, and create a new row from each Point.
I hope my intentions are clear and thanks for your help in advance!
I have a multi-level folders table, named folders with attributes of folder_id, parent_id and user_id, and have another table, users, contains all the user_id. I need to list all the users for each folder which has parent_id = 0 and its all sub-folders' users into one table. I have created a function to return a table with folder_id and user_id for one single folder. However, I don't know how to use this function to get the sub-folder's users and merge them together as one single table. Here is my function: CREATE FUNCTION [dbo].[FolderUsers] (@fid int) RETURNS Table AS Return (select folder_id, f.user_id from folders f, users u where f.user_id = u.user_id and folder_id = @fid)Go where @fid is the top folder with parent_id = 0 at here, the next level sub-folder's parent_id would be = @fid. I am thinking to have recursive call from the parent_id = @fid that returns another table and have to concatenate to the called table. I have been thinking of store procedure, "insert into" and so on, but don't know how to implement it. Do you have any good inspiration for me? Thank you in advance!

I have two tables. In tblUsers is all userdata. In table tblMoreInfo is some info on a user (0-15 records).Now I want to select tblUsers.username and tblUsers.usercode and the matching top 1 row tblMoreInfo.schoolname (top 1 based on tblMoreInfo.createdate) IF IT EVENT EXISTS from tblMoreInfo. If no matching record exists I want the value NULL to be returned for the schoolname...In all cases tblUsers.username must be unique (and I cant use the distinct keyword as im already using the row_number() function.Any help?Thanks!

I am trying to run queries on a table (table has zero rows). Inspite of giving 0 rows returned the query keeps on running and I have to cancel it. I tried inserting a dummy row into the table but even the insert operation is taking too long.Every query which I hit on the table just keeps on running without giving any result.
But this is not the case with other tables in the database.They are all running fine giving proper results. But this one table is behaving funny.
i want to have a user defined function or stored procedure(i don't know which one should be used, anyway!) which returns false if the table has no records, with the table name comes with a parameter.
