Return Subquery Result For Only First Row In Result

Apr 7, 2015

I'm using a subquery to return a delivery charge line as a column in the result set. I want to see this delivery charge only on the first line of the results for each contract. Code and results are below.

declare @start smalldatetime
declare @end smalldatetime
set @start = '2015-03-22 00:00' -- this should be a Sunday
set @end = '2015-03-28 23:59' -- this should be the following Saturday

select di.dticket [Contract], di.ddate [Delivered], di.item [Fleet_No], di.descr [Description], dd.min_chg [Delivery_Chg], dd.last_invc_date [Delivery_Invoiced],

[code]....

In this example, I only want to see the delivery charge of 125.00 for the first line of contract HU004377. For simplicity I have only shown the lines for 1 contract here, but there would normally be many different contracts with varying numbers of lines, and I only want to see the delivery charge once for each contract.

What is the easiest way to return rows 200 through to 300 of a 500 row result set using SQL? Is there a simple way of doing this or do I need to write some Transact SQL? Any ideas would be appreciated.

Return Result Through ODBC

Oct 4, 1999

Dear all,

We are doing a query to SQL database through ODBC, to return a field named 'description'. The field has a maximum length of 1024 characters, ie, it is defined as varchar(1024). However, ODBC only return the first 255 characters. To rub more salt to the wound, when we are trying to insert a row of data into the field, ODBC actually truncated all the data after the first 255 characters, resulted in a little disaster.

I don't think we have a problem in the C programs, since the whole thing works in a little test database. (also in SQL7) I suspect there is a setting somewhere, only that the documentation doesn't give me much chance to find it. Any hints is desperately needed!!

Thanks in advance!

The Statement Did Not Return A Result Set

Oct 28, 2007

I am using MSSQL 2000, SQL Server Developer Edition and product version is : 8.00.760 (SP3)

Application Server: JBoss v 4.0.4
Driver : sql 2005 driver.

Hi,

I am running my application in JBOSS and hibernate to do all the query to the DB. While we are testing our application, it is working fine for the 1st day of stress testing, however after running for one days, it starts throwing the following exception. This can occur in a number of method call with no fixed pattern. Anyone has any idea what is going on?

Return 2 Result Sets

Feb 29, 2008

Hi, I'm trying to return 2 different result sets using the below query mapped to 2 different variables in my execute sql task. I've tried this with one task and 2 seperate tasks but can't get it to work. Is this possible using only one task? It keeps giving me a result set error.

SELECT COUNT(*) AS DeceasedCount
FROM AMGR_User_Fields_Tbl
WHERE (Client_Id = '' or Client_Id is NULL) and Type_Id = 53

SELECT COUNT(*) AS LostCount
FROM AMGR_User_Fields_Tbl
WHERE (Client_Id = '' or Client_Id is NULL) and Type_Id = 469

Return Result Set From Stored Procedure

Dec 8, 2011

I know how to write a stored procedure that does various things to a database. I know that a stored procedure returns a value of 0 by default if it executes successfully, and a non-zero value otherwise. I know you can use output variables to return other values from a stored procedure. I am moderately familiar with these things.

But... how do I fashion it if I'm calling the stored procedure from VB.NET in a web application, and I don't just want a couple of variable values, I want the whole result set?

I know there's #temporaryTables that ...exist within the scope of the stored procedures... ##Globaltemptables... regular_tables... and @tableVariables. I'm reading furiously to figure out what these things...all...do... and I'm leaning in the direction of ... a variable table as an output variable, but I just don't know... how and what I can stuff that into in the front end so I can shove it into the nice and neat grid view thing.

(fyi, I'm trying to return a consolidated table of available rooms fitting the user's specified reservation dates and amenity preferences - that part, I've gotten done like a boss. It's...getting it back to the front end I'm struggling with.)

Big Queries Return Empty Result Set

Apr 22, 2004

Hello guys,

MS SQL server 2000 behavies strange with big queries that involves relatively large number of tables:
If I just enumerate columns I want to receive, the result set is empty. Adding * to the column list without making any change to where clause seems to solve the problem but I guess it's not the best practice.
The most amazing is that this behavior is not stable, so I suppose there's something to deal with server itself, not the application.
Has anybody suffered this problem and what solution was adopted?
Thanks for any information you can provide.

Return Result Not Working With IN Clause

Feb 28, 2008

I have a form that has many checkboxes (more than 40) that provide information about companies.

For example. Company ABC
Checkbox 1 (Windows XP)
Checkbox 2 (Windows Vista)
Checkbox 3 (Windows NT4)
etc.

I save these in a SQL table like the following
Row 1 - Col 1 (CompanyID), col2 (checkbox value)
Row 2 - Col 1 (CompanyID), col2 (checkbox value)
etc.. so a comapany can have multiple checkbox selected..

I am currently developing a report where the end user can select one or many of the checkbox to see if the company exist.

This is where I get stuck - I only want to return the results of the companies that meet the report selections. So if I want to see all the companies that current have Windows NT and Windows Vista...how would I build that querry based on the data model above.

I have tried using the IN clause - however that use the OR connector and doesnt show ONLY the compaines that meet. I have tried using a UNION and INTERSECT, and running the select statement many times.. (SELECT CompanyID from xx WHERE CheckboxVal = xx)
INTERSECT
(SELECT CompanyID from xx WHERE CheckboxVal = xx)
etc.. howevert this creates a very large quesry that is unable to be handled by SQL 2005. I get a error message asking to minimize the query.

Any suggestions on this please...this is my 4th day working on this..

Sometime ADODB Return No Result To Excel

Aug 3, 2007

Hi all, I have a strange situation.

I use VBA to call a MSSQL server 2000 to get data from one of the DB inside, using ADODB.

My problem is, the DB is around 20GB, and if we get data from it for few days, say 7 days, is fine. When I come to trying get more data like 1 month, the excel returns no data after waiting for about 30 sec.

The query is actually calling a stored procedure on the server side to return data.

I have add connectiontimeout=10000 to my connection string but still not working...

I run the same execute statement in query analyzer on the same machine using the Excel and it is fine. Around 2 minute waiting I can see my data. But in Excel, never.

Anyone can offer some helps to me? Thanks alot.

How To Return The Result Of An EXEC From A Function

Sep 21, 2007

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?

SQLServerException: The Statement Did Not Return A Result Set When Sp Uses Cursors

Jun 8, 2007

I'm trying to migrate to the 2005 JDBC driver against SQL Server 2000, but I'm getting the following exception: com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set. This is similar problem to a past thread: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=413019&SiteID=1
The difference is that my stored procedure uses cursors. This same stored procedure works fine with the 2000 JDBC driver.

Does anybody have any ideas how to resolve this problem?

Execute SQl Task Return Decimal Type Result

Dec 3, 2007

I am trying to have an Excecute SQL Task return a single row result set executed on SQL Server 2005.

The query in the Execute SQL Task is:
select 735.234, 2454.123

I get a conversion error when trying to assign to SSIS variables of type Double.
I have nothing configured in the "Parameter Mapping" tab.
I have the two SSIS Double variables mapped to the Tesult Name 0 and 1 in the "Result Set" tab

I don't want to use a for loop enumerator since there is a single row returned.

I simply want to assign these two values to SSIS Double variables (double is the closest match)

I can't even hack this by converting the decimals as string and then using DirectCast to convert them to Double.

Thanks for the help

PRINT '-------- ITEM Products Report --------'

DECLARE ITEM_cursor CURSOR FOR

execute (@qstring)

OPEN ITEM_cursor

FETCH NEXT FROM ITEM_cursor

INTO @ITEMCODE

WHILE @@FETCH_STATUS = 0

BEGIN

PRINT ' '

SELECT @message = '----- Products From ITEM: ' +

@ITEMNAME

PRINT @message

-- Get the next ITEM.

FETCH NEXT FROM ITEM_cursor

INTO @ITEMcode

END

CLOSE ITEM_cursor

DEALLOCATE ITEM_cursor

Why i use @qstring? It is because the query will be changed by different critiera.

Return Result From One Query As A Column In Other Query

Jun 3, 2004

I'm having a bit of a trouble explaining what I'm trying to do here.

I have 3 "source" tables and a "connecting" table that I'm going to use

tblContacts - with contactID, ContactName etc
tblGroups - with GroupID, GroupName
tblSubGroups - with SubGroupID, GroupID and SubGroupName (groupID is the ID for the parent Group from tblGroups)

They are related in a table called
tblContactsGroupConnection - with ContactID, GroupID and SubGroupID

One contact can be related to many subgroups.
What I want is a list of all contacts, with their IDs, names and what groups they are related to:

ContactID, ContactName, [SubGroupName1, SubGroupName2, SubGroupName3]
ContactID, ContactName, [SubGroupName1, SubGroupName3]
ContactID, ContactName, [SubGroupName3]

I'm sure there's a simple solution to this, but I can't find it. Any help appreciated. :)

Datareader Destination As Source For Other Datareader Source ?

Aug 30, 2006

HI!

as far as I know from docs and forum datareader is for .NET data in memory. So if a use a complex dataflow to build up some data and want to use this in other dataflow componens - could i use data datareader source in the fist dataflow and then use a datareader souce in the second dataflow do read the inmemoty data from fist transform to do fursther cals ?

how to pass in memory data from one dataflow to the next one (i do not want to rebuild the logic in each dataflow to build up data data ?

Is there a way to do this ? and is the datareader the proper component ? (because its the one and only inmemory i guess, utherwise i need to write to temp table and read from temp table in next step) (I have only found examples fro .NET VB or C# programms to read a datareader, but how to do this in SSIS directly in the next dataflow?

THANKS, HANNES
