Double quotes are not valid to enclose literals, you need single quotes. I would suugest before executing your sql string you print it (at least for debug) as it soon shows any syntax errors.

Hello,

Generally here, apostrophe is considered as escape sequence character
You may execute as

TransType = ''SI''

This may solve you problem

Use CHAR(39) for single apostrophe.

Good,but when you have complex query and in which you use multiple times single apostrophe then you can become confused by writing much '''' in query.

Hi,

How to remove the duplicate records with the old timestamp. Below is the table, contains 2 columns Bugdate and timestamp. I wanted to remove the duplicate records with the old time stamp. ie first three records. It would be pleasure if any one send me the query.

BugDate----     Timestamp
4/14/2009     12/8/2009 12:54.611
4/19/2009     12/8/2009 12:54.611
4/26/2009     12/8/2009 12:54.611

4/14/2009     12/8/2009 12:58.623
4/19/2009     12/8/2009 12:58.623

Some threads below, people have told how t osearch duplicate records from a table. Check that out. Once you have the records, just find the ones with older timestamp and delete them.

I believe it should be a mere customization of the same query.

I know the logic for how to get duplicate rows but I need to delete them. Below is the table and my logic for getting duplicate records with old timestamp. But I need to delete these records. Can you help by doing little modification in my code.

ProductID   BugDate     Bug     Timestamp
111           2009-04-12     1     2009-12-08 12:18:07.453
111           2009-04-14     2     2009-12-08 12:18:07.453
111           2009-04-19     1     2009-12-08 12:18:07.453

111           2009-04-12     1     2009-12-08 12:29:07.453
111           2009-04-14     3     2009-12-08 12:29:07.453
111           2009-04-19     2     2009-12-08 12:29:07.453

SELECT [Product ID],BugDate,Bug,[Timestamp]
FROM BugsDB_DefectVolume, (
   SELECT [Product ID] AS B, MIN([Timestamp]) AS S
   FROM BugsDB_DefectVolume
   GROUP BY [Product ID]) X
WHERE [Timestamp] = X.S and [Product ID]='111'

Try this.

First I am giving a sample demo and then I will modify your query

Sample demo

declare @t table(bugdate varchar(10),timestamps datetime)
insert into @t 
	select '4/14/2009','12/8/2009 12:54.611' union all
	select '4/19/2009', '12/8/2009 12:54.611' union all
	select '4/26/2009', '12/8/2009 12:54.611' union all
	select '4/14/2009','12/8/2009 12:58.623' union all
	select '4/19/2009','12/8/2009 12:58.623' union all
	select '4/26/2009','12/8/2009 12:58.623'

Query:

delete from @t where timestamps in(
select MIN(timestamps) from @t
group by bugdate
having (COUNT(timestamps)>1))

select * from @t

Output:

bugdate	timestamps
4/14/2009	2009-12-08 12:58:00.623
4/19/2009	2009-12-08 12:58:00.623
4/26/2009	2009-12-08 12:58:00.623

Coming to your code:

Try this

delete from BugsDB_DefectVolume where [Timestamp] in(

select [Timestamp] from (

SELECT [Product ID],BugDate,Bug,[Timestamp]
FROM BugsDB_DefectVolume, (
   SELECT [Product ID] AS B, MIN([Timestamp]) AS S
   FROM BugsDB_DefectVolume
   GROUP BY [Product ID]) X
WHERE [Timestamp] = X.S and [Product ID]='111' )X)Y

Hope this helps

but have one problem. if there are duplicate records that first time its working fine but when we execute second time all records were deleted from the table. I think we need to put a check some where in the logic.

Niladri_Biswas7-Dec-09 22:34

I guess, you can do 1 thing.

Put a check like if the timestamp field is not equal to getdate()

like

select

case when (timestamp = getdate())

then call the delete operation

end as checking

Hope this might help you

it will not work out. but the example and query you sent in the previous reply is working fine even we executed query many times.

delete from @t where timestamps in(select MIN(timestamps) from @tgroup by bugdate having (COUNT(timestamps)>1))..

As you have used having clause I think we need to put the same thing in my query. I tired but getting syntax errors... Can you think once again...

Got the solution.. below query will be workout

            DELETE T1
     FROM BugsDB_DefectVolume T1, BugsDB_DefectVolume T2
     WHERE T1.[Product ID] = T2.[Product ID]
     and T1.BugDate = T2.BugDate and T1.Timestamps < T2.Timestamps

Trigger in a certain period of time of day

Hi all,

I have two tables A(a1,a2,a3), B(b1,b2,b3) and a period of time Delta t [t1,t2].

When it is between t1 - t2 of time, if there is a row inserted in table A, the field b1 of table B will be updated such as b1=b1+1.

Moreover, I also have a web application which can assign value for t1, t2 through an aspx page.

Could you tell me how to do that?

Thank kiu so much.

If you are using SQL Server, you could set up a trigger on table a, so when a row is inserted it checks if the time is between t1 and t2, and if so update table b.

SQLServer Default Database Changed

Tim Carmichael7-Dec-09 5:46

On a SQLServer 2000 server, the default database for the user accounts was changed. This appears to have occurred for ALL users accounts, both network login names and SQLServer named accounts.

Any idea how this can happen?

Our DBA resigned Thanksgiving week, so there is no help onsite.

Thanks in advance,

Tim

There are multiple ways to change the default database for the user accounts. You will need to retrieve a backup to restore the old default databases for all users. You may need to talk to the previous DBA about this issue. It is time consuming to find the cause by yourself. Was the previous DBA happy or not?

Use this statement to verify what you think happened ...

select name,default_database_name,modify_date from sys.sql_logins

If, indeed the changes were made, you will see when they happened and someone here might be able to work you through fixing it.

You may want to start by changing your administrative passwords since your DBA left. Make sure to tighten up any remote access accounts, etc.

Users could access the system last Thursday; on Friday, they couldn't. The default database was changed to a database that is used for sending e-mail messages, so, they neither need nor have access to it.
The accounts (there are only a handful) have been manually updated.

David Mujica wrote:

Since this is a SQLServer 2000 node, the listed table didn't work, but it gave me enough information to move forward. I used the following:

select l.name, xdate1 as creation_Date, xdate2 as modify_date, l.dbid,
d.name as defaultdb
from sysxlogins l inner join
sysdatabases d on l.dbid = d.dbid

And that just opened up more questions...

One of the accounts was created in 2007, updated a minute later and not touched after that, but, they have a default database set to a database that didn't exist at the time.

As far as access rights, when someone leaves the company, their password is changed and remote access removed.
