hi friends,
I want a delete query to delete rows from multiple tables. but all the tables containg one command field as 'id'. and the deletion based on some input given to this common field at run time in msaccess. Please help. I am trying like this. But it gives Could not delete message.
DELETE contact.*, address.*
FROM contact, address
WHERE contact.consultantid=[@consultantid] and address.consultantid=[@consultantid];
Thanks in advance.
Regards,
Prya

You cannot perform a delete on two tables at once. You can perform two deletes, and this is what you should do.

also you could set up cascading deletes and then if you delete from one table the record gets removed from the related table. I'm never sure how much i like cascading deletes though. Pete's method is the one i would use in my code you can pass the two commands separated by ; if you only want to make 1 call (i believe)

You also need to be careful about the order of the delete statements if you are using foreign key constraints. In this case, you would need to delete from the address table before the contact table.

declare @ID as int<br />
set @ID=41 --instad 41 use parameter<br />
DELETE FROM contact WHERE ID =@ID<br />
DELETE FROM addressWHERE ID =@ID

If you are using SQL Server you can write a FOR DELETE trigger on the table 'contact'. Try this: -
--------------------------------------------------------------------------------------------------
CREATE PROCEDURE DeleteContact @consultantid int
AS
DELETE FROM contact WHERE consultantid=@consultantid
--------------------------------------------------------------------------------------------------
Now create a trigger on the table 'contact': -
--------------------------------------------------------------------------------------------------
CREATE TRIGGER DeleteAddress ON contact
FOR DELETE
AS
CREATE TABLE #DeletedContacts
(
consultantid int
)
INSERT INTO #DeletedContacts SELECT consultantid FROM deleted
DELETE FROM address WHERE consultantid IN (SELECT consultantid FROM deleted)
--------------------------------------------------------------------------------------------------
Now, you execute the stored procedure: EXEC DeleteContact <anyconsultantid>
After it deletes from the table 'contact' the trigger will be excuted and it will delete corresponsing rows from the table 'address'.

Hy,
Backup a database with fulltext catalog doesn't work properly with a maintenance plan?

Where I can find model's of plan maintenance for medium database (300 000 records per year) ?
Any ideas.

I have no idea what you mean by "table creation wizard". However, in both the design view and the diagram view you can select multiple columns then right click and select "Primary Key" from the menu.

Have a look in the SQL server Books On Line (look up CREATE TRIGGER in the index, it will give you all the details and a few examples)

Hey all,
how do I update table1 depending on its relation with table2 and table3?
eg.,
UPDATE table1 SET table1.col1 = (SELECT table4.col1 FROM table4 WHERE table4.col2 = "asdfgf" ) WHERE table1.col2 = table2.col1 AND table1.col3 = table3.col1
Is the above correct?
Or should I use JOIN to do the above? If so, how do I do it?
Can anyone help?
Thanks in advance.

As far as my knowledge goes, I guess the above query should work as expected. A join is not needed in this case. A join is needed only when you need to combine data from multiple tables based on certain criteria.

Can anybody help ?
This is ASP.Net code
I'm trying to send Null value to stored procedure
and this can be done like this:
...
cmdInsert.Parameters.Add( "@test_var", DBNull.Value )
...
Question
How this can be done with old ASP code
If I try something like this I got error
...
Set objParam = objComm.CreateParameter("@test_var", adVarChar, adParamInput, Len(test_var), Null)
objComm.Parameters.Append objParam
...
How can I do this?
Is there in old ASP code something like "DBNull.Value" in ASP.Net
Thank u

I think you get the prize for the most vague question of the day.
What database are you using? Is it a commerial offereing? If yes then it may already have .NET providers. Is it a database engine you created yourself? Then you will have to read up on Data Providers (The interefaces in the System.Data namespace will be a good referrence)

I have two database : Db1 and Db2
I want to fill tables of Db2 with some fields of Db1 tables
also I do`nt want to use from Import & Export wizard
do you have any idea

If they're on the same server, you can prefix the owner.tablename with the database. So, suppose that you had Database1.dbo.MyTable and Database2.dbo.MyTable, you could do the following (as an example):
INSERT INTO Database2.dbo.MyTable<br />
SELECT * FROM Database1.dbo.MyTable
Obviously, you will need the relevant permissions in both dbs to do this.

My database table consists a Field (Called ApplyDate)store the integer data, like "20061122" represent 22 nov 2006. i need to filter the data for whole November 2006, but if i write SELECT....WHERE ApplyDate = 200611 , it cannot get the data out because the last two digit no specified. So , how i write the SQL Where statement if i want to select Whole Nov 2006 ? (for example, 20061101...20061130 also acceptable)
Best regards,
Chee ken

why dont you use like command
example
SELECT....WHERE ApplyDate like '200611%'
this will give you proper result
