On weekends I have Integrity Checks scheduled to run. Many of these fail for individual databases because users do not log off and the databases cannot be switched to single user mode.
I have checked Books-on-line and have not yet stumbled onto a TSQL command that breaks the connections.
Is there a TSQL command to do this? If not, how can these connections be broken?
I have a few databases on this Windows 2000 Server running
SQL 2000 which were detached from SQL 7.0 and attached to
SQL 2000.
The problem is the Maintenance Plans (Integrity Checks
keep failing on SQL 2000. I 'DTS'ed a SQL 7.0 database to
this SQL 2000 server and ran the Maintenance Plans on that
database. Works fine only for the DTS'ed database.
What am I missing ???
:confused:
Hello, I had a DB Maintenance plan, the schedule is every day, but today I found teh 'Integrity checks job is failed". What is that mean? How to check this. Thanks.

My SQLMaint integrity checks consistently fail when the "Repair any minor problems" option is checked. The reported reason is that the database must be in single user mode. This doesn't seem practical. Am I missing an option somewhere?
View 1 Replies View RelatedThe integrity checks job on the user databases failed over the weekend and here is the error I got from the report:

Googled the issue and found some articles on this issue, but wanted to also run it by you.
I looked at the maint plan properties and under the integrity tab of the maint plan attempt to repair any problems is checked, this is what I think:
Since attempt to repair is checked, the db was trying to repair the issue and since users were logged into the system
it could'nt repair the issue as the system needs to be in single user mode. I think if we uncheck the attempt to repair
option, then the job would run fine.
But is this the best way to do? how about the errors it was trying to repair? Do we have to fix the error's it was trying to
fix later by changing the db to single user mode.
PLease let me know your ideas, thanks!!
I am using sql server 2012 with HADR (Always on with sql cluster).
We have database maintenance plans through wizard for full backup & DBCC CHECK DB. It was running successfully but it failed with the below error

I can able to take the backup from query window. It is succesful. The Sql Agent has full permissions. I don't think there are any recent changes happen.
Hi,
I want to automate the process of database integrity checks in sql server any suggestions how to do
Suppose you have two (or more) tables with foreign key constraints. Myquestion is thus:Is it better to check if the fk exists before you try to perform theinsert or let SQL do it for you?On one hand, if you check yourself and the key does not exist you cangracefully handle it (maybe exit out of method with error). If you letSQL do it, the server will throw an error which cannot be suppressed.On the performance side, you doing the check will incur a slight (VERYslight) hit since SQL will ALSO check anyways.

Hi experts,
What is the difference between, Creating rules and creating checks on a field?
They both look the same.

Don't sit back because of failure. It will come back to check if you still available. -- Binu
I have a transaction table which has Date as datetime field, amount and account number. i want to find out count of checks that were written in a period of 4 days which exceeded i.e. > $400, between 401 and 500, > 501 for a single month. the table has data for more than a year and i want the results then grouped in monthly format like in
OCT between 300 & 400 #30 (30 customers gave checks total worth $300-$400 within any 4 consecutive days period in the month of OCT )
between 400 & 500 # 20
> 501 # 10
NOV between 300 & 400 #30
between 400 & 500 # 20
> 501 # 10
and so on for a 6 month period.
What daily/weekly checks do you guys currently perform on your servers and databases?
I recently ran across with an article from SQLServerCentral that listed a couple of daily checks that I'm thinking about implementing on my environment, and some of them are:
DB Missing Recent Backup - Report
DB Missing Recent Log Backup - Report
Drives Low on Disk Space - Report
Error Log Messages Report - Report
Instance Recently Restarted - Report
Job Failures - Report
Large Databases Log File - Report
I already have in place:
Verify is SQL Agent Service is running
Check Disk Space Available
Since I'm going to spend some time on this, I was wondering if there's anything else that you guys have in place or any other 'nice to have' that you guys also might have, so I don't leave anything behind...
Thanks!

I have two connections in a package pointing to two different databases
on the same server. I have to insert records from 'DB1' table 'Gender1'
to 'DB2' table 'Gender2'. Before I do that though, I have to make sure
the minimum value (of all the Gender Keys that are going to be
inserted) of 'DB1' 'GenderKey' (which is an identity field) is greater than the
maximum value of DB2-GenderKey (which is a primary key but not an
identity field). How can I do this simple check? I have to do this process for many different tables ....... Gender table is just an example. If someone can give an detailed explanation on which tasks to use and how to use them (as I am relatively new to SSIS) that'd be great.
Hi all,
I'm trying to use a custom check constraint to insert into a table. I have created a function that checks an item against a authorization date as well and I've coupled this into the constraint. So for example, my function starts:
Code Snippet
ALTER FUNCTION {function1} (@ItemID INT, @AuthDate DATETIME)
RETURNS INT
AS
BEGIN
DECLARE @Ret INT
SET @Ret = 0
IF NOT EXISTS(SELECT top 1 ItemID FROM {table1}
Where b1.ItemID = @ItemID
AND @AuthDate <= ISNULL(b1.expirydate, @AuthDate))
BEGIN
SET @Ret = 1
END
ELSE
BEGIN
SET @Ret = 0
END
RETURN(@Ret)
END
GO
Now i couple that into a check constraint for the same table:
Code Snippet
ALTER TABLE {table1} ADD CONSTRAINT {contraint_name} CHECK (([function1]([ItemID], [AuthorizedDate])=(1)))
GO
Now, when i insert a record into this table with an Authorized Date greater than the ItemDate it should set the @ret value to 1. This is being passed back to the constraint should set 1=1 which is true and therefore should allow an insert, however, i cannot do this. I think this is because it inserts the record and THEN does the check which makes it fail. Is there anyway to do this check before the INSERT without having to use a trigger? I dont want to use a trigger because when we're doing an insert for bulk rows, performance decreases correct?
Using the new referential integrity constraints that will be made available, will it allow us to manually define the relationships between entities even if there is no true foreign key constraints setup in the database?
Lets say we deleted the FK_Orders_Customers in Northwind between orders and customers.
Or is this ability available now?
Thank for your time.
I'm trying to simplify a SQL Stored Procedure.The query accepts an int, @ItemTypeID intI have the Query:SELECT ... FROM ItemList WHERE ItemTypeID = @ItemTypeIDor, if @ItemTypeID is 0,SELECT ... FROM ItemList Is there a way to do this query without doing:IF @ItemTypeID = 0BEGIN ...SELECT QUERY...ENDELSEBEGIN ...SELECT QUERY...END?

When I schedule the job , for every hour , it gives me an blank mail only with the subject ' status of database on testsql' even though no databases are offline.

I want to check to see if a database exists in SQL Server 2005 Express... using VB.NET (or C#)... Can not use the SQLConnection Object... because I get a Failed Login Attempt... regardless if the DB does not exist or if it is because the User Login is incorrect
Is there some way to check to see if the Database exists (is attached) to the SQL Server 2005 Express Engine?

Hi,
Does TSQL provide methods to check if a file exists?
For example, a TSQL script will read data in a .dbf file into SQL Server. It will check if the file exists before read. How to do this check?
Thank you.
I have a VM set up for offloading DBCC checks. Specs are below. I've read through this, but I'm not seeing the performance gains by enabling the trace flags and using the physical only switch.
Is the whole drawback that I'm on SATA storage? Is there a VM configuration with the CPU I can/should change? I've been playing with MAXDOP trying to see if I can get any benefits but I'm not seeing a much.

Databases - Dynamic Log File Growths Remaining Alarm
Dynamic Log File Growths Remaining alarm becomes active when a non fixed size log file in any database is in danger of running out of space to grow. It is raised when a log file is almost full and the file cannot automatically grow enough to relieve the problem.
We have our databases with Enable Autogrowth (in Megabytes), and then a Maximum File Size (Limited to a MB value).
Example: If one of the database logs (or possibly filegroup primary) picks up another extent and is about 5 extents (arbitrary value) away from running out of growth room, an alert would be sent to an email address/profile.
P.S. Yes, there are multiple databases on this one instance and the script should loop to run through all of them.
Hi All,
I Have a nifty little stored procedure that takes data from an ASP form post
and inserts the data into two tables. However what I really need this to do
before the insert is check whether there is already a record that matches
some of the criteria, and if so returns an error "This Username already
exists" and only if there isn't a record that matches the criteria is the
record inserted.
my current stored procedure looks like this -
Code Snippet@siteid int,@companyname nvarchar(50),@address nvarchar(500),@phone nvarchar(50),@fax nvarchar(50),@email nvarchar(225),@url nvarchar(225),@companytype nvarchar(50),@billingcontact nvarchar(50),@name nvarchar(50),@AccountType nvarchar(50),@PASSWORD nvarchar(50),@AccountLive nvarchar(50),@EmployeeLevel nvarchar(50)ASDeclare @NewID INTINSERT INTO dbo.JBClient(JBCLSiteID, JBCLName, JBCLAddress, JBCLPhone, JBCLFax, JBCLEmail, JBCLCompanyType, JBCLURL, JBCLAccountType, JBCLAccountlive, JBCLBillingContact)VALUES (@siteid, @companyname, @address, @phone, @fax, @email, @companytype, @url, @AccountType, @AccountLive, @billingcontact)SELECT @NewID = SCOPE_IDENTITY()INSERT INTO dbo.JBEmployee(JBEClientID, JBESiteID, JBEName, JBELevel, JBEUsername, JBEPassword, JBEAddress, JBEPhone)VALUES (@NewID, @siteid, @name, @EmployeeLevel, @email, @PASSWORD, @address, @phone)
The values that i need to check against are -
@siteid
@email
in the table dbo.JBEmployee against columns JBESiteID & JBEUsername
What i would really like to do if a record exists is return the user to an
ASP page, which contains all of the variables previously enterred -,
@siteid int,
@companyname nvarchar(50),
@address nvarchar(500),
@phone nvarchar(50),
@fax nvarchar(50),
@email nvarchar(225),
@url nvarchar(225),
@companytype nvarchar(50),
@billingcontact nvarchar(50),
@name nvarchar(50),
@AccountType nvarchar(50),
@PASSWORD nvarchar(50),
@AccountLive nvarchar(50),
@EmployeeLevel nvarchar(50)
together with a message that says "This Username already exists"
Does anyone have any idea how to do this???
Many thanks
I have to perform several data checks before loading data into target table. For example I am having 1 flat file with below column
Id Name Age
Int Varchar(100)Â Int
My requirement is to create  package, checks will be performed on each record, column of the files. Any records which failed the checks considered as error records and will be written to the exception table.
I am not sure I need more integrity on my DB. My DDL are down below.
thanks

Hi all,
Is there any way to check the integrity of .Mdf file before attaching it to a database means to check whether its valid (or) not.
Thanks.
//Najeed
Where should tests for data integrity be done, a few examples:
Inserting data but the underlying data has changed?
Adding data, say an order item row, but since going to that screen the order (and as a result all its order items as well) have been deleted?
It's just I'm starting to see even the simplest of stored procedures as being quite complicated. What puzzles me is a I see lots of INSERT stored procedures with none of this checking in, or returning error codes?
So are they badly done or am I missing somethign?
Question:
What is used to enforce referential integrity ?
Answer: Triggers; Foriegn Keys.
what is Foreign Keys ?
How do you enforce referential integrity in SQL between tables?
Thanks.
I having a problem importing a text file into an existing table using the DTS import wizard. The problem I am having is, I am getting an error message stating: Integrity violation: attempt to insert null data or data which violates constraints. The column the error is referenced to is an identity field and I am not trying to insert any data into the field. I have the allow insert identity box checked in the transformation section. Does anyone know about how to solve this problem.
Thanks
James
