another question

Thanks for the note Vishal,
What if each had a date. So that
create table #cartype(manufacturer varchar(500), itemnumber int, datemade date)
insert into #cartype values('Toyota',1, 4/6/2004)
insert into #cartype values('Toyota',1, 4/6/2004)
insert into #cartype values('Honda',2, 4/6/2004)
insert into #cartype values('Honda',2, 4/6/2004)
insert into #cartype values('Toyota',1, 4/7/2004)
insert into #cartype values('Honda',3, 4/7/2004)
insert into #cartype values('GE',3, 4/7/2004)
insert into #cartype values('GE',3, 4/7/2004)
So that
insert into #cartype values('Toyota',1, 4/6/2004)
insert into #cartype values('Honda',2, 4/6/2004)
Would get deleted because there the exact same records (same number) of records are duplicated for that date.
But the records:
insert into #cartype values('Toyota',1, 4/7/2004)
insert into #cartype values('Honda',3, 4/7/2004)
insert into #cartype values('GE',3, 4/7/2004)
insert into #cartype values('GE',3, 4/7/2004)
The GE records would stay because all of the records are not duplicated, just the GE records are so I want to keep all the records.
Thanks for any ideas!
Try query as follows:
delete a
from #cartype a join
(select manufacturer, datemade, count(*) cnt
from #cartype
group by manufacturer, datemade
having count(*) > 1) b on a.manufacturer = b.manufacturer and
a.datemade = b.datemade and b.cnt <>
(select count(*)
from #cartype x
group by manufacturer
having x.manufacturer = b.manufacturer)

|||Here is what I have done to make it fit my query. Here are my records:
store, deliverydate, itemnumber, qty
006SS,04/15/2004,070100,018
006SS,04/15/2004,090096,018
006SS,04/15/2004,070100,018
006SS,04/15/2004,090096,018
(this should get deleted, exact same as 2 lines above)
007SS,04/15/2004,030498,020
007SS,04/15/2004,030498,020
007SS,04/15/2004,030498,020
007SS,04/15/2004,090495,020
007SS,04/15/2004,090495,020
(all lines should stay because it is not exact same.)
selext a.*, cnt
from tblItemOrder a join
(select itemnumber, quantity, store, deliverydate, count(*) cnt
from tblItemOrder
group by itemnumber, quantity, store, deliverydate
having count(*) > 1) b on a.itemnumber = b.itemnumber and
a.quantity = b.quantity and a.store = b.store and a.deliverydate = b.deliverydate and b.cnt <>
(select count(*)
from tblItemOrder x
group by store, deliverydate
having x.store = b.store and x.deliverydate = b.deliverydate)
I get all records that have duplicate lines, not just the ones with same count of duplicate records (storeno, deliverydate).
Any ideas? I have thought about it many different ways and have not come up with a solution yet. Thanks again,
|||hi ashley,
Remember SELECT and DELETE are different statements. DELETE will delete
the data from the table while with the help of SELECT statement you can
filterout the rows from the table.
See following example:
create table tt
(store varchar(50),
deliverydate datetime,
itemnumber varchar(50),
qty int)
--insert some data
insert into tt
select '006SS','04/15/2004','070100','018' union all
select '006SS','04/15/2004','090096','018' union all
select '006SS','04/15/2004','070100','018' union all
select '006SS','04/15/2004','090096','018' union all
select '007SS','04/15/2004','030498','020' union all
select '007SS','04/15/2004','030498','020' union all
select '007SS','04/15/2004','030498','020' union all
select '007SS','04/15/2004','090495','020' union all
select '007SS','04/15/2004','090495','020'
--Try this query:
select a.*
from tt a join
(select store, deliverydate, itemnumber,count(*) cnt
from tt
group by store, deliverydate, itemnumber
having count(*) > 1) b on a.itemnumber = b.itemnumber and
a.store = b.store and a.deliverydate = b.deliverydate and 1 not in
(select 1
from tt x
group by store, deliverydate, itemnumber
having x.store = b.store and x.deliverydate = b.deliverydate and
x.itemnumber <> b.itemnumber and count(*) = b.cnt)

another question

Hi guys,
please create a table in tempdb running following
USE tempdb
CREATE TABLE delete_me (c1 int, c2 int )
INSERT delete_me (c1, c2)
SELECT 1, 1 UNION SELECT 2, 2 UNION SELECT 3, 3 UNION SELECT 4, 4
Then running the script below you can get (I do) the error message :
Server: Msg 207, Level 16, State 1, Line 1
Invalid column name 'c3'.
But sometimes it works. The workaround seems to be to wrap UPDATE statement
up into EXEC, - it works always. Why is that?
BEGIN TRAN
ALTER TABLE delete_me
ADD c3 int
-- EXEC ('UPDATE delete_me SET c3 = 0')
UPDATE delete_me SET c3 = 0
ALTER TABLE delete_me
ALTER COLUMN c3 int NOT NULL
ROLLBACK TRAN
Thanks
AlexThats quite a normal behaviour. Object resolution takes place if the
object is already know so, this will fail due to the non existing
column. Look for
http://msdn.microsoft.com/library/d...>
_07_5wa6.asp
"Note Deferred Name Resolution can only be used when you reference
nonexistent table objects. All other objects must exist at the time the
stored procedure is created. For example, when you reference an
existing table in a stored procedure you cannot list nonexistent
columns for that table."

What is your SQL Server version?
It worked fine on my workstation (SS2000,SP3,Personal Edition)

Jens pointed to the note which explains clearly why it happens. What it
worries me though that this behaviour is not consistent. Most of the tine it
acts according to BOL and that particular note, but sometimes the resolution
stage comes through with flying colors when referencing a missing column for
existing table. But this is a bit different story...

Another Problem with variables

I have this...

declare
@.variable int

create table #tmp_datos
( variable int null )

insert into #tmp_datos
exec sp_prueba_era

select @.variable = variable
from
#tmp_datos

select @.variable

drop proc sp_prueba_era
go

create proc sp_prueba_era @.variable int output
as
declare
@.cmd varchar(250)

are there other way to do this??are you able to connect to your server using isql ?|||Yes, but I need to pass dinamically the name of the server, by this I'm using strings and exec...

But the original query it's this...

Select @.var = Select 1 from xx

I need to pass this to string...|||Originally posted by ramshree
are you able to connect to your server using isql ?

Not clear what you are trying to do.

but this works :

declare @.var char(100)
select @.var = 'select * from sysobjects'
exec (@.var)

-|||I'm trying to store a value in a variable into select statement, but my select statement it's a string that I'm going to execute with exec clause..., so I can't to do this...

declare
@.variable int,
@.cmd varchar(100)

select @.cmd = "select @.variable = 20"
exec (@.cmd)

because @.variable it's not a defined variable..., so how can I do for make a string like this...|||Maybe there is something, i haven't understood, but why is it so important, that the select is stored in the string?|||Hi,
Hope this is wat u want--
here i am assigning the count of the number of records to the variable @.varCountTable. but the whole string has to be executed in EXEC().
Personalize it to ur needs--
SET @.varSelectString = N'SELECT @.varCountTable = COUNT(*) FROM CPGSTAGEDB.DBO.' + @.varTableName
EXEC SP_EXECUTESQL @.varSelectString, N'@.varCountTable nvarchar(50) OUTPUT',@.varCountTable = @.varCountTable OUTPUT
