Hi
I have two tables which I'm combining.
Select employeeID as id, startDt as startDate from Table1
union all
Select CustomerID as id, startDt as startDate from Table2
order by startDt
This works fine, unfortunately, my problem is I only want to display the first latest customer. In a Union All, how do i distinguish whether I'm ordering the table it is trying to union or the actual unioned table tiself?
For example, this does not work.
Select employeeID as id, startDt as startDate from Table1
union all
Select top 1 CustomerID as id, startDt as startDate from Table2
order by startDt desc
order by startDt

hello,
I have 2 tables which contain a lot of articles, and they have same structure.
what I want to do is that, select top 10 articles from each table and then union those records to another table, also I need to order these articles in desc order by their added date before i union them.
what I know is that for union sql phrase , there is only one order by is allowed, so how could I order those 2 tables before i union them.
thanks

Hello,
I am trying to use dynamic ORDER BY with UNION in a stored procedure but I keep getting this error message:
ORDER BY items must appear in the select list if the statement contains a UNION, INTERSECT or EXCEPT operator.
The ORDER BY works fine without the UNION, and the UNION works fine without the dynamic ORDER BY (just putting an ORDER BY works fine)
Here is the whole query in case this helps, thank you

Hi,
I'm currently have a problem with a query using a top clause. When I run it by itself as a single query, I have no problems and the results are valid. However, if I try duplicate the query after a union clause, the order by ... desc doesn't order properly.
The following is the query I'm using along with the results. Then I'll have the query I was trying to unite and the results (date ranges selected were the same in both):
QUERY 1
select top 1 (s.ldate), v.mdtid, po.odometer, pi.odometer, (pi.odometer-po.odometer) as 'Total Miles'

ON v.vehicleid=es.vehicleid
JOIN Events PO
ON PO.schid=es.schid
AND PO.EvStrId=ES.EvStrId
AND po.activity=4
JOIN Events PI
ON PI.schid=es.schid
AND PI.EvStrId=ES.EvStrId
AND pi.activity=3
WHERE es.providerid in (0,1,4)
and s.ldate>=?
and s.ldate<=?
and v.mdtid=20411
order by s.ldate desc
RESULTS 1

As you can see, the results are sorted very differently. Is there any way to have the order by apply to both queries?
Thanks!

All,I've seen several posts regarding using UNION or UNION ALL to mashtogether two or more resultsets into a single result set, but can'tseem to find enough info here to help me answer my particularquestion.I have a stored procedure that gets the column names in a particularformat (i.e. "chassis_id"|"chassis_description"|"modify_date") as wellas actual data for a given table (in a quote-separated, pipe-delimitedmanner i.e. "1"|"description for the chassis"|"2004-09-08").I'd like to get both of these resultsets and mash them together. Thisworks, but when I need to order the second resultset (i.e. select *from chassis order by chassis_id), SQL Server returns an errorcomplaining about the chassis_id column name (invalid column name'chassis_id') in the Order By clause.From what I can tell, I'm using the UNION and Order By in correctly,but I'm not sure exactly what's wrong with it. If I take out the OrderBy, everything works great. Although I would like to be able to ordermy second resultset (in the same sproc) if possible.The actual queries I'm running are actually quite long, but here's onethat's a bit shorter to help illustrate:SELECT '"app_group_id"|"app_group_name"|"create_date"|"create_by"|"modify_date"|"modify_by"'UNION ALLSELECT + ISNULL(CONVERT(varchar,app_group_id), '') + '|'+ SUBSTRING(RTRIM(LTRIM(CONVERT(varchar, 1))), 1,0)+ '"' + ISNULL(CONVERT(varchar(1000), +REPLACE(CONVERT(nvarchar(4000),app_group_name), '"', '""')), '') +'"|'+ SUBSTRING(RTRIM(LTRIM(CONVERT(varchar, 2))), 1,0)FROM app_grouporder by app_group_idThank for any help on this./bc

Hi all,
I have the following UNION ALL statement that is my attempt to gather data for the past 5 weekdays (adding a "dummy" row for today's data).
I want the final output to end up in descending order, so for today, I would want today first, then Tuesday, then Monday, then Friday, then Thursday (provided there is data for each sequential day - if not, you get the idea, I want to select back to get the latest 5 days, most recent to oldest).
This select fails, because it doesn't like the ORDER BY in the subqueryselect
CASE
WHEN DATENAME(dw, GETDATE()) = 'Monday' THEN
'MON'
WHEN DATENAME(dw, GETDATE()) = 'Tuesday' THEN
'TUES'
WHEN DATENAME(dw, GETDATE()) = 'Wednesday' THEN
'WED'
WHEN DATENAME(dw, GETDATE()) = 'Thursday' THEN
'THUR'
WHEN DATENAME(dw, GETDATE()) = 'Friday' THEN
'FRI'
END AS Dow, 'N/A' AS Freight
UNION ALL
(select top 4
CASE
WHEN DATENAME(dw, [OrderDate]) = 'Monday' THEN
'MON'
WHEN DATENAME(dw, [OrderDate]) = 'Tuesday' THEN
'TUES'
WHEN DATENAME(dw, [OrderDate]) = 'Wednesday' THEN
'WED'
WHEN DATENAME(dw, [OrderDate]) = 'Thursday' THEN
'THUR'
WHEN DATENAME(dw, [OrderDate]) = 'Friday' THEN
'FRI'
END as DOW,
CAST(CONVERT(int, (Freight * 100)) as VARCHAR(10)) as Freight
from Northwind.dbo.orders where employeeid = 9 order by [OrderDate] desc )
I know you can't use an ORDER BY in a subquery, UNLESS the subquery also uses a TOP n (which this one does)...but does anyone know why this isn't liking my code?
I got the select to work the way I want it to by doing the following (really UGLY) code...SELECT U.DOW, U.Freight FROM
((select
GETDATE() as [OrderDate],
CASE
WHEN DATENAME(dw, GETDATE()) = 'Monday' THEN
'MON'
WHEN DATENAME(dw, GETDATE()) = 'Tuesday' THEN
'TUES'
WHEN DATENAME(dw, GETDATE()) = 'Wednesday' THEN
'WED'
WHEN DATENAME(dw, GETDATE()) = 'Thursday' THEN
'THUR'
WHEN DATENAME(dw, GETDATE()) = 'Friday' THEN
'FRI'
END AS Dow, 'N/A' AS Freight )
UNION ALL
(select h.OrderDate as [OrderDate], h.DOW, h.Freight FROM
(select top 4
[OrderDate] as [OrderDate],
CASE
WHEN DATENAME(dw, [OrderDate]) = 'Monday' THEN
'MON'
WHEN DATENAME(dw, [OrderDate]) = 'Tuesday' THEN
'TUES'
WHEN DATENAME(dw, [OrderDate]) = 'Wednesday' THEN
'WED'
WHEN DATENAME(dw, [OrderDate]) = 'Thursday' THEN
'THUR'
WHEN DATENAME(dw, [OrderDate]) = 'Friday' THEN
'FRI'
END as DOW,
CAST(CONVERT(int, (Freight * 100)) as VARCHAR(10)) as Freight
from Northwind.dbo.orders where employeeid = 9 order by [OrderDate] desc ) H)) U
order by OrderDate descbut am still confounded about why my original sub-select is rejected with such impunity.
My confusion seems likely related to understanding the set theory or basic concepts of the building of the select/Union rather than the way I am using the ORDER BY syntax, but I just can't seem to explain it to myself.
Thoughts?
Thanks!

This query works perfectly and orders by just as I need
Code:
Select
'1st' As [Type],
#Uno.ID
#Uno.Address,
#Uno.shippingInfo
FROM #Uno
[Code] ....
However, when I use it in a Union All so I can pull data from 2 diff tables, the order by statement no longer works. How can I order by data in 2 tables?
Code:
Select
'1st' As [Type],
#Uno.ID
#Uno.Address,

Hi,
I'm trying to write a UNION statement with 2 selects and can't figure out for the life of me how to do it.
select top 10 * from tblusers ORDER BY dateJoined
UNION
select top 10 * from tblusers ORDER BY lastLogin
The union works fine without the order by's, but I really need the order by's in there and I don't understand why its so difficult to do. Surely there must be some other strategy?
Any help is much appreciated.. thanks!!

I am trying to combine 2 queries, each with their own 'order by' and I am having trouble.
This is just an example, not what I'm trying to do, my query is more elaberate but looks simular to this.
SELECT TOP 10 *, 'FieldA' AS SortedBy
FROM TableA
Order By FieldA Desc
UNION ALL
SELECT TOP 10 Precent *, 'FieldB' AS SortedBy
FROM TableA
Order By FieldB Asc
Anyway not to get the following error?

Can anyone help as to how to get this to work? dbo.parseInt is a Function which sorts Alpha Numerically. If I removed the top part of the UNION, the Procedure works fine.

now i want to ad a limit to this statement, but i can't get it working. i have tried this:SELECT * FROM (SELECT [Name], [EventID] AS [ItemID], [TourID], [Date], NULL AS [StartDate], [Date] AS [SortDate], [Type] FROM [Events] WHERE [TourID] IS NULL AND AccessLevel <= @AuthenticationLevel UNION SELECT [Name], [TourID] AS [ItemID], [TourID], NULL AS [Date], [StartDate], [StartDate] AS [SortDate], '2' AS [Type] FROM [Tours]WHERE AccessLevel <= @AuthenticationLevel) ORDER BY [SortDate] LIMIT 2

I'm new to SQL stored procedures, but I'm looking to be able to select order by statement.
declare @OrderBy
@OrderBy = 'first_name'
Select first_name,last_name from table1
Union
Select first_name,last_name from table2
if @OrderBy = 'first_name' begin
Order By first_name
else
Order By last_name
end
You'll have to excuse my if statement if the syntax is incorrect (used to only writing asp ifs :P). Thanks for any help

Hi!
I'm trying to get the results from three different tables, where they have some of the same results. I'm only interested in where they match and then trying to order by date (that's in three columns - M, D, Y). I read previous post in 9/07 but the result doesn't seem to order correctly. It does not have any rhyme or reason to the outputed results as it bounces back and forth through Oct, Nov and Dec posting and throughout all three tables. Here's my query below. Any ideas how I can get my ordering correct for all three tables to display all Oct, all Nov and all Dec?
Thanks so much
select date3, date2, date1, who, what
from
(
select date3, date2, date1, who, what from shows
union
select date3, date2, date1, who, what from shares
union
select date3, date2, date1, who, what from soiree

a order by date3, date2, date1

I have the following as part of a union query:
CONVERT(CHAR(8), r.RRDate, 1) AS [Date]
I also want to order by date but when I do that it doesn't order correctly because of the conversion to char data type (for example, it puts 6/15/05 before 9/22/04 because it only looks at the first number(s) and not the year). If I try to cast it back to smalldatetime in the order by clause it tells me that ORDER BY items must appear in the select list if the statement contains a UNION operator. I get the same message if I try putting just "r.RRDate" in the ORDER BY clause. It's not that big of a deal - I can lose the formatting on the date if I need to to get it to sort correctly, but this query gets used frequently and I'd like to keep the formatting if possible.
Thanks,
Dave

Struggling to come up with an overall sum for each individual user when using the below code
SELECT
Practice.ibvStaffCategorisation.StaffId
,Practice.ibvStaffTotalsCL2Y.Period
,SUM(Practice.ibvStaffTotalsCL2Y.ChargeableMinutes) AS Sum_ChargeableMinutes
,SUM(Practice.ibvStaffTotalsCL2Y.NonChargeableMinutes) AS Sum_NonChargeableMinutes
[Code] ....
As I am using union all it shows two values for each user, the problem is I am getting the data via lookup like below
=Lookup(Fields!StaffId.Value, Fields!StaffId.Value, Fields!Sum_ChargeableAmount.Value, "ABSTimeRollingY")
I don't think I can use a Sum within a lookup so at the moment it is only bringing through the first value for each user but I would like it to bring through both.
Is there a way to do this within the dataset or via the query in the table?

I've got a user defined table type called StringDictionaryTVP:
CREATE TYPE [dbo].[StringDictionaryTVP] AS TABLE(
[key] [varchar](500) NULL,
[value] [varchar](500) NULL
)
Ideally I would like to be able to have a # of columns and directions in this table like so:
DECLARE @OrderByClause StringDictionaryTVP
INSERT INTO @OrderByClause([key], [value])
values('gender','desc')
INSERT INTO @OrderByClause([key], [value])
values('name','asc')
Since our database can be a bit sizable, I'd also like to use Common Table Expressions so I can page through them fairly easy.So my standard cte is something like this:
DECLARE @PageIndex INT = 0
DECLARE @PageSize INT = 20
;WITH results_cte AS ( SELECT U.*, ROW_NUMBER() over ( ORDER BY name ) RowNum
from Users U)
SELECT * FROM results_cte
WHERE RowNum > @Offset AND RowNum <= @Offset + @PageSize
So where 'ORDER BY name' is I'd like to use the @OrderByClause in some sort of dynamic way. I've tried all kinds of stuff but even something like this doesn't get the actual column name I need
;WITH results_cte AS ( SELECT U.*, ROW_NUMBER() over ( ORDER BY (select top 1 [key] +' '+ [value] from @OrderByClause) ) RowNum
from Users U)
I may be chasing the wrong stick, but outside of dynamic sql, is something like this possible?

Hi all!
I have created (in CLR) a user defined aggregate. The scan order of this aggregate is important, because it return different results for different orders.
When i use it with a single group (using order by and where) is working fine.
For example
select id, dbo.cmp(myclolumn) as myres from (select top 100 percent * from mytable order by id,clmdate) where id=10 group by id
This works correctly. Now lets expand it by removing where id=10 clause
select id, dbo.cmp(myclolumn) as myres from (select top 100 percent * from mytable order by id,clmdate) group by id
I get slightly different results from what the right result must be.
Any idea?

SQL Server 2008 r2...
I have a query which does 3 selects and Union ALLs each to get a final result set. The performance is unacceptable - takes around a minute to run. If I remove the Union All so that the result sets are returned individually it returns all 3 from the query in around 6 seconds (acceptable performance).
Any way to join the result sets together without using Union All.
Each result set has exactly the same structure returned...
Query below [for reference]...
WITH cte AS (
SELECT A.[PoleID], ISNULL(B.[IsSpanClear], 0) AS [IsSpanClear], B.[SurveyDate], ROW_NUMBER() OVER (PARTITION BY A.[PoleID] ORDER BY B.[SurveyDate] DESC) rownum
FROM[UT_Pole] A
LEFT OUTER JOIN [UT_Surveyed_Pole] B ON A.[PoleID] = B.[PoleID]
[Code] .....

I have a user defined table type with two columns: ID: int, Value: float.Also, I have a table with different columns.I have a stored procedure:
ALTER PROCEDURE [dbo].[MyProcedure]
@List AS dbo.MyUserDefinedTableType READONLY
AS
BEGIN
SET NOCOUNT ON;
[code]....
I want to add "order by Value" to this stored procedure. Like below:
ALTER PROCEDURE [dbo].[MyProcedure]
@List AS dbo.MyUserDefinedTableType READONLY
AS
BEGIN
SET NOCOUNT ON;
[code]....
But this way is not true, and I get error when i debug my application.I fill this user defined table type in c# with data of a DataTable.

Hi. Thru a sproc, I drop & re-create some temp tables.When I call that sproc from the client, though, I cannot drop thetables.I need to allow the user, say "Alex", to drop/create tables (actually,that would be DDL). Which role should "Alex" assume ? How do I do that?I run the following sproc named, say, "CREATE_TABLE" (SNIP):__________________________________________________ __________________Set @StrSQL = 'if exists (select * from dbo.sysobjects where id =object_id(N''[dbo].[' + @TableName + ']'') and OBJECTPROPERTY(id,N''IsUserTable'') = 1) drop table [dbo].[' + @TableName + ']'Exec (@StrSQL)Set @StrSQL = 'CREATE TABLE [dbo].[' + @TableName + '] ([GROUP] [varchar] (6) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,...........[Stuff] [varchar] (20) COLLATE SQL_Latin1_General_CP1_CI_AS NULL) ON [PRIMARY]'Exec (@StrSQL)Set @StrSQL = 'GRANT SELECT , UPDATE , INSERT , DELETE ON [dbo].['+ @TableName + '] TO [Alex]'Exec (@StrSQL)__________________________________________________ __________________As you can see, it is dynamic, because I need to repeat it for many@TableName values - that means, further more, that I will be executingthis in the context of the current user, Alex, and therefore I have togive Alex rights to both executing the sproc and to the tables referredto by the sproc, as specified by @TableName.I created a _TEST sproc which contains only the following:_______________________________________________CREATE PROCEDURE _TEST ASDROP TABLE [dbo].[SomeTable]RETURN_______________________________________________When I execute it from the client, thru ADODB, on user Alex, I get"User does not have permission to execute this operation on tableSomeTable"The table has been created thru "CREATE_TABLE", abovePlease help, I have to finish this tomorrow, and I'm under tons ofpressure.Thanks a lot,Alex.

Why the sequence different?
select * from (
select id=3,[name]='Z'
union all select 1,'G'
union all select 2,'R'
union all select 4,'Z'
) as t
order by [name]
--result:
---------
--1 G
--2 R
--4 Z
--3 Z
select * from (
select id=3,[name]='Z'
union select 1,'G'
union all select 2,'R'
union all select 4,'Z'
) as t
order by [name]
--result:
----------
--1 G
--2 R
--3 Z--changed
--4 Z

Hello,
I am creating a windows application that is not going to be used in a controlled environment like a LAN or some other network, so I want to include a local database in the install of this app. Ideally, I would like to use SQL 2005 Express like you would MSDE or Access, but I am not sure if the user must have SQL Server installed on their machine in order for this to work and I don't have a machine without it to test on.
Any help on this is greatly appreciated.
Thanks,
Derek

Hi all,
I have a Union All transformation with 4 inputs and one output when I debug the package the sum of the different inputs rows does not match the row count in output.
I don't understand, I've used the Union All transform many times and I've never seen this.
Any idea why this could happen ?
