Hi,
I have a sql 2005 function who return a distance from 2 zipcodes. This function is called from a Stored procedure like this :
SELECT *, dbo.fn_GetDistance (...) AS Distance
In this function, i have a Latitude and i want this Latitude to be also returned.
It is possible or a function can return only one variable?
If it is possible, what's the syntax of it?
Thanks in advance
I'm a Reporting Services New-Be.
I'm trying to create a report that's based on a SQL-2005 Stored Procedure.
I added the Report Designer, a Report dataset ( based on a shared datasource).
When I try to build the project in BIDS, I get an error. The error occurs three times, once for each parameter on the stored procedure.
I'll only reproduce one instance of the error for the sake of brevity.
[rsCompilerErrorInExpression] The Value expression for the query parameter 'UserID' contains an error : [BC30654] 'Return' statement in a Function, Get, or Operator must return a value.
I've searched on this error and it looks like it's a Visual Basic error :
http://msdn2.microsoft.com/en-us/library/8x403818(VS.80).aspx
My guess is that BIDS is creating some VB code behind the scenes for the report.
I can't find any other information that seems to fit this error.
The other reports in the BIDS project built successfully before I added this report, so it must be something specific to the report.
BTW, the Stored Procedure this report is based on a global temp table. The other reports do not use temp tables.
Can anyone help ?
Thanks,
I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]
/*
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
Example:
exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0
*/
@ProcessName varchar(50)
, @FileCreateDate datetime
, @IsNewFile bit OUTPUT
AS
SET NOCOUNT ON
--DECLARE @IsNewFile bit
DECLARE @CreateDateInTable datetime
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.
General

Connection = MyServerDataBase
SQLSourceType = Direct input
IsQueryStoredProcedure = False
BypassPrepare = True
I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output

Expressions is empty.
When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ...

SSIS package "MyPackage.dtsx" finished: Failure.
The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Thanks for your help.
I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!

I want to write a function that returns the physical filepath of the master database for its MDF and LDF files respectively. This information will then be used to create a new database in the same location as the master database for those servers that do not have the MDF and LDF files in the default locations.
Below I have the T-SQL for the function created and a test query I am using to test the results. If I print out the value of @MDF_FILE_PATH within the funtion, I get the result needed. When making a call to the function and printing out the variable, all I get is the first letter of the drive and nothing else.
You may notice that in the function how CHARINDEX is being used. I am not sure why, but if I put a backslash "" as expression1 within the SELECT statement, I do not get the value of the drive. In other words I get "MSSQLData" instead of "D:MSSQLData" I then supply the backslash in the SET statement. I assume that this has something to do with my question.
Any suggestions? Thank you.

Hello,
I have a stored procedure that accepts a number of different input parameters that populate some variables in my stored procedure.
I want to have this stored procedure return nothing if some of these variables aren't filled out (they are populated by a search page the user fills out).
I'm not very familiar with writing stored procedures, so any help you can give me is appreciated.
Thanks!
When I create a tableadapter to do an insert it added
SELECT EventDate, EventID, org_id, ROMEventID FROM ROMEvents WHERE (ROMEventID = SCOPE_IDENTITY())
at the end. This looks useful to me since it implies that I can access ROMEventID which is the auto-incremented identity field.
How would I reference the variable in my .cs file?
My insert is working as ROMEventsTableAdapter ROMEventInsert = new ROMEventsTableAdapter();
ROMEventInsert.InsertIntoROMEvents(theDate, EventID, org_id);
Thanks for any help
Hi
I want a functionality such that I want to return a select query resultset and a varchar variable from a procedure. How can I achieve that,and moreover how can I fetch them in ASP??
Waiting for someone to shed a light of hope.
Thanx a lot
Why does this not work?
declare @ret varchar(50)
DECLARE @X SQL_VARIANT
set @X=10
SET @ret=select SQL_VARIANT_PROPERTY(@X,'BaseType')
Just trying to assign the SQL_VARIANT_PROPERTY return value to @ret and it issues an error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query.
But I don't want to convert I just want to assign the result to the variable.
what's confusding is that you can do this:
if(select SQL_VARIANT_PROPERTY(@X,'BaseType'))='int'
So I assume I should b able to do the above.

Is it possible in SQL 2000 to return a table variable from dynamic sql? We need to have some code that looks kind of like this:
declare @qry varchar(8000)
declare @sourcetable varchar(100) -- name of source table
declare @mytable table (ID_Num int identity(1,1), Child_Key varchar(100))
set @sourcetable = (select tablename from tblConfig where app = 1)
set @qry = 'insert into @mytable
select * from @sourcetable'
execute (@qry)
if (select count(*) from @mytable) > 0
begin
'insert into myFinalTable
select * from @mytable where blah blah blah
I can get the first part to work by declaring the table variable (mytable) in the dynamic sql, but I can't figure out how to return the table object.
What I'm trying to do is provide a solution where users can upload an image and a description, to a database, so I'm trying to insert the title and description then return the @@identity for the image upload function which will name the image like this

I cant seem to get the identity to return to my script.

Hi,
I am trying to return [string/SqlString] from a CLR function, but it was truncated at 8000 characters.
How can I solve this problem and return varchar(MAX)?
Thanks
Hi guys!
the problem is this:
I have a procedure that execute a function and i want to catch the return function value but i'm getting a null value.
I'm using:
exec @a = <function>
but the @a variable is allways null...
If i exec the function directly, i get the correct value.
What am i doing wrong?
Thanks in advance.
I have a function that is using a select case decision structure to arrive at a return value:
[dbo].[fn_Window]
(@Start AS INT,
@End AS INT) RETURNS VARCHAR(5)
AS
BEGIN
SELECT
CASE
/*** Pick up the extended periods here ***/
WHEN @Start = 1 AND @End = 1 THEN 'TRUE'
ELSE 'FALSE'
END
END
**** from here how do I get the function to return true or false? ****
Can I assign the select case result to a variable? If so how?
I have a stored proc that builds a character string from a number of rows returned from a select query. Is there anyway to insert a carriage return after I append the value of each row to the string variable?
Thanks in advance,
Chris
hey all,
I have the following query:
ALTER PROCEDURE [dbo].[sp_SelectMostRecentArticle]
AS
BEGIN
DECLARE @article_id INT
SELECT @article_id = (
SELECT TOP 1 article_id
FROM article
ORDER BY article_id DESC
)
DECLARE @comment_count INT
SELECT @comment_count = (
SELECT COUNT(comment_id)
FROM comment
JOIN article ON article_id = comment_article_id
GROUP BY article_id
HAVING article_id = @article_id
)
SELECT TOP 1 article_id, article_author_id,
article_title, article_body, article_post_date,
article_edit_date, article_status, article_author_id
article_author_ip, author_display_name,
category_id, category_name--, comment_count AS @comment_count
FROM article
JOIN author ON author_id = article_author_id
JOIN category ON category_id = article_category_id
GROUP BY article_id, article_title, article_body, article_post_date,
article_edit_date, article_status, article_author_ip,article_author_id,
author_display_name, category_id, category_name
HAVING article_id = @article_id
END
GO
as you can see, im trying to return a comment_count value, but the only way I can do this is by defining the variable.
I have had to do it this way, because I cannot say COUNT(comment.comment_id) AS comment_count or it returns an error that it cant reference the comment.comment_id.
But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id.
And i cant add a join, because it would return the amount of rows of the comment...
unless someone could help with what i Just decribed (as i would prefer to do it this way), how would i return the variable value as part of the select statement?
Cheers
I have a parent package (i.e. P) and a child package (C). I was able to easily pass a variable value from P to C. And C did computations and get a result (i.e. integer) and stored this integer to a variable (x).
Now I want the value of "x" to be passed back to P and store in P's variable (say Px). Anyone knows how to ?
Thanks

I have concatenated a long Select Statement and assigned it to a variable. (i.e.)
@a = Select * from foo ---Obviously mine is much more robust
How do I execute @a to actually Select * from foo?
Cannot see where I am going wrong. I always get a value of 0. I know my function works correctly, so it must be the VB.

and have the output have columns (id, data, whatever, col1, col2) where col1 and col2 are returned by fnMyFunction
possible? easier way? thanks in advance...
Greetings,
Is there anything new on returning max of two values in SQL 05? There seems to be nothing I have searched everywhere. Only option might be to create my own UDF or do a CASE statement, but I could not believe my eyes there is no such thing?
Thanks
Hi I need a function which gets 3 parameters and input and returns 4 integers as output.
I don't know how to return 4 integers as output
any idea is appreciated.
I have an existing function and need to alter function to give result of the parent-description until its parent is reached.
--CREATE TABLE
CREATE TABLE [dbo].[CityData](
[Id] [int] NULL,
[ParentID] [int] NULL,
[City] [nchar](20) NULL,
[Location] [nchar](50) NULL,
[Amt] [int] NULL
) ON [PRIMARY]
[Code] ....
Is it possible to write dynamic sql on scalar function and assign the value to return value? I like some thing like below but it is not working...
Thanks
______________________________________________________________________
set @sql = 'select @CallLegKey= min(calllegkey) as CallLegKey
from rt_'+@platform+'_CallLegs
where datediff(day,convert(datetime, CallEndTime) ,'''+cast(@today as varchar(20))+''') = '+cast(@cutoff as varchar(5))
exec @sql
return @CallLegKey
I have created a function to return values, which works fine, but I can't do calculations in it.
CREATE FUNCTION [dbo].[tf_Asset_Portfolio](@deal_id int,
@as_of_date datetime)
RETURNS TABLE
AS
RETURN ( SELECT DISTINCT dbo.Assets.issue_id, SUM(DISTINCT dbo.Assets.par_amount) AS par_amount, SUM(DISTINCT dbo.Assets.par_amount) AS market_value
FROM dbo.Issue INNER JOIN
dbo.Assets ON dbo.Issue.issue_id = dbo.Assets.issue_id INNER JOIN
dbo.Issuer_Rating_History ON dbo.Issue.issuer_id = dbo.Issuer_Rating_History.issuer_id
WHERE (dbo.Issuer_Rating_History.as_of_date <= @as_of_date)
GROUP BY ALL dbo.Assets.issue_id, dbo.Assets.deal_id, dbo.Issue.default_date
HAVING (dbo.Assets.deal_id = @deal_id) )
I need to do calculations on market value based on the default date.
If default date isn't specified then it should be 100% of par amount.
If default date is less than one year ago - 65% of the par_amount.
If default date is one or more years ago - 0.
I have no idea about how to do this and everything I try wont work.
I created another function to do the calculations and this seems to work, but it only does one record instead of all of them.
CREATE FUNCTION dbo.tf_Asset_Portfolio2
(@deal_id int,
@as_of_date datetime)
RETURNS @Market TABLE
(issue_id int, par_amount money, market_value money)
AS
BEGIN
DECLARE @ReturnDate datetime
DECLARE @DD datetime
DECLARE @PA money
DECLARE @MV money
DECLARE @ID int
DECLARE @DateD int
SELECT TOP 1
@ReturnDate = LAST_BATCH
FROM master..sysprocesses
WHERE SPId = @@SPID
SELECT @ID = issue_id FROM Assets WHERE Assets.deal_id = @deal_id
SELECT @PA = SUM(DISTINCT par_amount) FROM Assets WHERE Assets.issue_id = @ID AND Assets.deal_id = @deal_id
SELECT @DD = default_date FROM Issue WHERE Issue.issue_id = @ID
SET @DateD = DateDiff("yyyy", @DD, @ReturnDate)
If @DD = Null
BEGIN
SET @MV = @PA
END
Else If @DD > @ReturnDate
BEGIN
SET @MV = @PA
END
Else If @DateD < 1
BEGIN
SET @MV = @PA * .65
END
Else If @DateD >= 1
BEGIN
SET @MV = 0
END
insert into @Market
(issue_id, par_amount, market_value)
values
(@ID,@PA,@MV)
RETURN
END
I need to combine the functionality of being able to return mutliple records that isn't in the 2nd function and being able to calculate the market value which isn't in the first one. Please help. Thank you in advance.
