I'm new to SQL and i've searched everywhere for the answer to this question but I can't seem to find the anwer anywhere. My question is.....
If there are multiple rows for a specific field, is there a way in SQL to only return the last row based on that specific field.
For example, I wrote a query that returns a list of patients who have a specific lab type. If a patient has had several labs taken, they show up in the result set several times (for each lab date). I only want to return the most recent lab date.
FROM dbo.lab_result LEFT OUTER JOIN
dbo.mpi ON dbo.lab_result.blind_key = dbo.mpi.chart LEFT OUTER JOIN
dbo.mpi_xref ON dbo.mpi.chart = dbo.mpi_xref.blind_key
I have a package that I have been attempting to return a error code after the stored procedure executes, otherwise the package works great.
I call the stored procedure from a Execute SQL Task (execute Marketing_extract_history_load_test ?, ? OUTPUT) The sql task rowset is set to NONE. It is a OLEB connection.
I have two parameters mapped:
tablename input varchar 0 (this variable is set earlier in a foreach loop) ADO. returnvalue output long 1
I set the breakpoint and see the values change, but I have a OnFailure conditon set if it returns a failure. The failure is ignored and the package completes. No quite what I wanted.
The first part of the sp is below and I set the value @i and return.
Why is it not capturing and setting the error and execute my OnFailure code? I have tried setting one of my parameter mappings to returnvalue with no success.
This is my function, it returns SQLDataReader to DATALIST control. How to return page number with the SQLDataReader set ? sql server 2005, asp.net 2.0
Function get_all_events() As SqlDataReader Dim myConnection As New SqlConnection(ConfigurationManager.AppSettings("...........")) Dim myCommand As New SqlCommand("EVENTS_LIST_BY_REGION_ALL", myConnection) myCommand.CommandType = CommandType.StoredProcedure

Variable Pages is global integer.
This is what i am calling DataList1.DataSource = get_all_events() DataList1.DataBind()

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 :
I am trying to bring my stored proc's into the 21st century with try catch and the output clause. In the past I have returned info like the new timestamp, the new identity (if an insert sproc), username with output params and a return value as well. I have checked if error is a concurrency violation(I check if @@rowcount is 0 and if so my return value is a special number.)
I have used the old goto method for trapping errors committing or rolling back the transaction.
Now I want to use the try,catch with transactions. This is easy enough but how do I do what I had done before?
I get an error returning the new timestamp in the Output clause (tstamp is my timestamp field -- so I am using inserted.tstamp).
Plus how do I check for concerrency error. Is it the same as before and if so would the check of @@rowcount be in the catch section?
So how to return timestamp and a return value and how to check for concurrency all in the try/catch.
by the way I read that you could not return an identity in the output clause but I had no problem.
i have using BCP to output SP return data into txt file, however, when it return nothing , it give SQLException like "no rows affected" , i have try to find out the solution , which include put "SET NOCOUNT ON" command before select statement, but it doesn't help :(
anyone know how to handle the problem when SP return no data ?
I have a stored procedure that selects the unique Name of an item from one table.
SELECT DISTINCT ChainName from Chains
For each ChainName, there exists 0 or more StoreNames in the Stores. I want to return the result of this select as the second field in each row of the result set.
SELECT DISTINCT StoreName FROM Stores WHERE Stores.ChainName = ChainName
Each row of the result set returned by the stored procedure would contain:
ChainName, Array of StoreNames (or comma separated strings or whatever)

The problem I am having is that it returns the correct value if there is a record that exists or indeed if it doesn't BUT ... even when a record exists it still carries out the insert!

I have set of procedures that implement business logic in such a way that I am just interested to return only one row when there could possibly be millions of them. Those procedures are in this form
SELECT Top 1 SGP.GroupID
FROM dbo.SubGroupPerm SGP
INNER JOIN dbo.GroupPermStats GPS on SGP.GroupID = GPS.GroupID
INNER JOIN dbo.IMISProduct IP on GPS.ProductID = IP.ProductID
INNER JOIN dbo.HasMeasureGroup HMG on SGP.GroupID = HMG.GroupID
WHERE SGP.SubscriberID = 40335
AND HMG.MeasureTypeID = 119
AND GPS.IndustryCode = 'CT'
Such tables are properly indexed and most queries return results using clustered index seek/index seek operations. Unfortunately, in presence of large tables I don't get the desired response time because query generates massive IOs. I was wondering if someone could possibly have another clever way to re-write above query where we just have to return one row?
in my package i am executing a stored procedure from execute sql task which is something like DECLARE @return_value int EXEC @return_value = [dbo].[NextDigitalDataLoad] SELECT 'ReturnValue' = @return_value GO
Now based on the value returned by this i have to check in a dataflow task whether the file content is correct or not. please tell me how to do
I have a table that contains multiple entries per a specific Id similar to the following: 1 09-01-2007 1 09-02-2007 1 09-15-2007 1 09-06-2007 2 09-03-2007 2 06-09-2007 2 07-09-2007 3 01-01-2007 3 02-02-2007 I need to get a single row back for each id which corresponds to the row with the minimum datetime. Using the example I would need to return: 1 09-01-2007 2 06-09-2007 3 01-01-2007 Anyone have any ideas on how to accomplish this with a TSQL query? Thanks.

Hello, I created a stored procedure which selects a value according to ContentId. I know that will be only one value returned or none. So if a record is found I want to return the string contained in ContentHtml. Else I want to return the string "NotFound" Could somebody help me out with this?

I have the following stored procedure... CREATE Procedure UserGetInfo2 (@UserID int, @SystemTimePeriodID int )As set nocount onSELECT Users.UserId as UserID, Users.UserName as UserName, Users.RealName as RealName, UserTimePeriod.BudgetCode as BudgetCode, UserTimePeriod.SystemTimePeriodID as SystemTimePeriodID, Users.Password as Password, Users.SSN as SSN, Users.Location as Location, Users.ScheduleType as ScheduleType, Users.EmployeeType as EmployeeType, Users.TimeAccounted as TimeAccountedFROM Users INNER JOIN UserTimePeriod ON Users.UserId = UserTimePeriod.UserIDWHERE (users.userID= @UserID) AND (UserTimePeriod.SystemTimePeriodID = @SystemTimePeriodID)returnGO The problem lies in that when a person has a SystemTimePeriodID over a certain value, there is no UserTimePeriod record since it has not been created yet. Obviously, I need to wrap this in an IF...EXISTS IF EXISTS (SELECT UserTimePeriodID FROM UserTimePeriod WHERE (SystemTimePeriodID = @SystemTimePeriodID) AND (UserID = @UserID)) (the SELECT above, since that's what needs to come back if the data exists) ELSE Do the same select but put in a static value for BudgetCode, like '0000' GO How could I do the part where the IF...EXISTS fails? I'm... not sure I can use RETURNS, since it feeds into this recordset: rstUserInfo2.Open "UserGetInfo2 " & Request("UserID") & ", " & Request("SYSTIMEPERIODID") and later uses values from that RecordSet, such as <td><%=rstUserInfo("BudgetCode") & ""%></td>

I guess a pretty basic sql question here. I am using tableadapters. And some of the queries have multiple parameters. But often a parameter is at a default or null - wherein I'd like to be able to pass it in and have it not filter at all - ie., return everything. Simple example: Select * from ReportsWhere ReportID = @ReportID If I have a dropdownlist of reports where the values are ReportIDs - but the topmost unselected value is say "", then the results will be generated by Select * from ReportsWhere ReportID = '' Whis not what I want. What I would want is simply Select * from Reports or Select * from ReportsWhere ReportID = ReportID So how can one setup say an ObjectDataSource or somehow handle this where I don't need to use dynamic sql to expand/contract my where clause? Really need hlpe on this and hope I've made my question reasonably clear. Thanks.
Hi, I have an sql query like this :DECLARE @TableName varchar(200), @ColumnName varchar(200), @EmployeeID varchar(200), @Result varchar(200);SET @TableName = 'Customer';SET @ColumnName = 'First_Name';SET @CustomerID = 28;-- This line return ErrorSET @Result = EXEC ('select' + @ColumnName + ' from ' + @TableName + ' where Recid = ' + @CustomerID + '');Print @Result; I am pretty sure the SELECT statement in EXEC will only return 0 or 1 record. But how to capture result from EXEC? Thanks
