I'd like to be able to see if credentials (server/instance, username/password or win authentication) specified by an administrator are actually able to connect to a database at my application installation time. I'm using WISE if that matters at all. How can I go about accomplishing this? Can it be done with something like osql.exe??
|

|
|

Yes, you can test your credentials. Execute a command like select count(*) from myTable and redirect the output to a file, then parse the file for the expected results and if there is no error you have validated that your username/password combination is correct.
Do this through osql.

Hi,
I have configured 2 SQL Server 2005 instances to replicate using Merge Replication. This is just a test environment at the moment, therefore both instances are on different servers but within the same domain and both running under the same administrator accounts.
The replication seems to run smoothly in that the snapshot agent runs successfully and then the subscriber synchronises with no errors. But, when I run my app on the subscriber I get a error when trying to perform a particular task:
Invalid object name 'dbo.MSmerge_genvw_5A046C944AD94C85AA554B95189A5399'.
The said task is calling a stored procedure which I have defined and which I can see has been replicated to the subscriber. I am new to replication so not entirely sure what is going on. Any help would be greatly appreciated.
Also, it may be worth pointing out that the subscriber is an express version, therefore all agents are running on the publisher.
Thanks.

Just in case anyone is interested, I solved the problem by replacing the SQL Express Server with the full version. All seems to be working correctly now.

Hi all,
I created a table in which there r n fields and in that two of them are date field i.e., startdate and enddate.
Now i want to write a query,to fetch the records from table which comes under startdate and enddate.
so,i need a help how to write the query.
Thanks in advance.

|
|
|

What you did so far? Have you try to write a query?
As I could understood you then query should be like:
select startdate,enddate from mytable where startdate >'2009.12.01' and enddate > '2009.12.22'

Try this
declare @t table(somevalue varchar(100),startdate datetime, enddate datetime)
insert into @t
select 'somevalue1','01/14/2009', '01/20/2009' union all
select 'somevalue2','01/15/2009', '01/22/2009' union all
select 'somevalue3','01/18/2009', '01/31/2009' union all
select 'somevalue4','02/01/2009', '02/10/2009' union all
select 'somevalue5','05/14/2009', '05/20/2009'
I want to get the records where between '01/14/2009' and '02/01/2009' (inclusive)
Query:
select * from @t
where startdate >='01/14/2009' and enddate <='02/01/2009'
Output:
somevalue startdate enddate
somevalue1 2009-01-14 00:00:00.000 2009-01-20 00:00:00.000
somevalue2 2009-01-15 00:00:00.000 2009-01-22 00:00:00.000
somevalue3 2009-01-18 00:00:00.000 2009-01-31 00:00:00.000

I think the error says it all. It seems you are trying to run the stored proc in the database you are restoring, which obviously you can't

hey ashfield thanks for reply
i found the answer
before running restore command i have to use any other databse to make the restoring database free. After that when we run restore commands it works great.
Thanks for all ur replies

i usually have to Sp that Closes the Connection before i do a Back or Restore.
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[sp_ClearDatabaseConnections]
@DBNAME VARCHAR(255)
AS
SET NOCOUNT ON
DECLARE @SPID INT, @STR VARCHAR(255)
DECLARE USERS CURSOR FOR
SELECT SPID
FROM MASTER..SYSPROCESSES
WHERE DB_NAME(DBID) = @DBNAME
OPEN USERS
FETCH NEXT FROM USERS INTO @SPID
WHILE @@FETCH_STATUS <> -1
BEGIN
IF @@FETCH_STATUS = 0
BEGIN
SET @STR = 'KILL ' + CONVERT(VARCHAR, @SPID)
EXEC (@STR)
END
FETCH NEXT FROM USERS INTO @SPID
END
DEALLOCATE USERS
as you can see it accept the name of the DB that you want to Restore.

i have database of sql
in User table there is field which contain encrypted password
this database is using with an application. so i know the string using which these passwords are encrypt so please can any one help me how can i get that passwords.
Regrads
|
|
|
|
|
If it's properly done you can't get the unencrypted passwords from the database.
The normal procedure is that you encrypt the supplied password with the same algorithm as was used when storing it in the database, and then compare.

I want to build a trigger for updating a summary table in SQL Server.
I have a summary table with records listing all the individual tables in my database. When I add a new record to the individual tables I wish to for it to update the summary record for the latest data.
Example:
When adding a new record with the date, I want the date to be entered in my summary table as the last date entered for that table, the name of the table will be listed.
I could do this with a stored procedure, but I would rather this be automatic with a trigger.
Can anyone help me with this, thanks in advance.

This is a really dumb idea, doubling your transaction cost to support a summary table that you query how often. Putting in a trigger (triggers are evil, like cursors) for such a trivial, non essential operation is not good.
Create a view or a stored proc to get the information when and if you need it.
A trigger is exactly like a proc except it can reference the inserted/updated record it is called from. Read BOL for some examples.

You have a begin tran on the outside of a while loop and have a rollback on the inside with an unconditional commit on the outside. If a rollback occurs, the loop continues transaction-less and the commit will execute anyway = your error 3902. I would not wrap a transaction around a while loop if there was another way (there is!).
Never issue a commit or rollback without checking to see if there is actually a tran.
if @@trancount > 0
rollback transaction
I would use a try-catch, without a doubt. Heres generally how a transaction could be handled:
begin try
begin transaction
--dml statement here
if @@trancount > 0
commit transaction
end try
begin catch
if @@trancount > 0
rollback transaction
print error_message() --(execute my error handler)
end catch
Some of the other wierd messages you are getting is because the proc failed to issue a commit or rollback at all leaving 'things' in an un-committed state. Until you have verified that the proc you are developing will always close the trans - issue either a commit or rollback after each 'test'.

Hi I am trying to create a stock scanner for my website. The user would choose and add certain criterias one by one, and a dynamic SQL statement would need to be created on the fly to retrieve the data.
Currently I am able to do this by appending pieces of SQL string after a long SQL string like the following:
Whenever "Add Criteria" button is pressed:
newQuery = "AND criteria > x"
userCriteria = userCriteria + newQuery
When "Retrieve Information" button is pressed:
Querystring = "Select * WHERE Date = date " & userCriteria
Is there a more efficient mechanism? If not that's also fine as it currently works well, but I just need some reassurance from experts. Thanks!

If it works then you can only improve the structure of the query otherwise it is an exercise in string concatenation.
If the where clause is the only dynamic piece and the elements are known you can use something like
Where (IsNull(@AttrID, -1) = -1 OR AttrID = @AttrID)
where the default value is null or -1. Caveat, too many of these (about 6 IIRC) MAY affect the query performance I believe. I use it all the time and have had up to 8 elements in the where clause and it worked fine. The only benefit is it is not dynamic, not a huge issue!

I have a stock time series data in which a numerical indicator fluctuates over time. If I want to find out for each stock that has its indicator now over 30, how many days since the last time this indicator is less than 30?
In other words, how many days since the last time the stock's indicator crosses above 30?
Just for your reference, currently I have the following:
SELECT ticker,
DATEDIFF(d,(SELECT MAX(DATE) FROM....),'12/21/2009')
WHERE Indicator > 30 AND Date = '12/21/2009'
I'd greatly appreciate any help! If possible please provide a sample code.
By the way, thank you Ashfield for your help on a similar question last time, later I was able to understand the code you gave me and utilized it in different ways. This is a bit more difficult for me though.

How about something like
select ticker,datediff(day,t.date,(select max(date) from table t1
where t1.ticker = t.ticker and t1.indicator < 30))
from table t
You may have to play about a bit, but it should be somewhere close
