I have 2 tables that are joined together by a primary key (Order Number). Can I use one SQL query to delete from both of the tables. One table contains the order information from a client (Order Number, Customer Name etc). The other table has order information (Order Number, Item Number, Quantity Ordered etc.)
I need one statement that will allow me to remove the items from both tables. Can this be done.
Thanks in Advance

Hello,
How can I delete duplicate entries from tables in my database using Query Analyzer, as there are many duplicate entries in my tables, I want to delete them.
Thanks in advance,
Uday.
This a microsoft SQL 2000 server.
I have a DB with mutliple tables that have a column called "Date_stamp", which is used as a primary ID.
Here is my problem:
Some of tables have a bad datetime entry for the "Date_stamp". The bad entry is '2008-3-18". I need to delete this entry from every single table that has a name similary to 'Elect_Sub%Daily'.
I know how to get the user table names from the DB as follows:
SELECT name
FROM dbo.sysobjects
WHERE xtype = 'U' and name like 'Elect_Sub%Daily'
What I need to do is have a query that will basically scroll through the tables name produced by the above query and search and delete the entries that read '2008-3-18".
delete from tableName where Date_Stamp = '2008-3-18'

Hello,
To delete all tables from my database I use:
SELECT 'DROP table ' + table_NAME
FROM INFORMATION_SCHEMA.tables
To get the list of the tables. Then I run that list:
DROP table Folders
DROP table Files
...
Because of relationships I need to run it various times until all the tables disappear. Is there a way to everything in one command?
Thank You,
Miguel

I am working on IBUYSTORE's db. I have added a backoffice/admin to the site.
I have a page where I retrieve a customer's details based on the customerid such as the following:
Dim Ssql As String = "SELECT O.CUSTOMERID, C.CUSTOMERID, C.PASSWORD, C.FULLNAME, C.EMAILADDRESS, O.ORDERID, OD.ORDERID , OD.PRODUCTID FROM customers AS C , ORDERS AS O , ORDERDETAILS AS OD WHERE C.customerID=O.CUSTOMERID AND OD.ORDERID=OD.ORDERID AND C.customerID = @cust_ID"
CMD As New SqlCommand(Ssql, oConn)
CMD.Parameters.Add("@cust_ID", id)
I am also using a sqldatareader.
I have a delete button. If the site manager clicks on that button i want to delete all that customer's details including all his orders from both orders and orderdetails tables.
I am not sure how to accomplish it.
The tables are as follows:
Customers: Orders: OrderDetails
customerid customerid orderid
orderid
I tried the following delete:
strDelete = "DELETE FROM CUSTOMERS where CustomerID=@CUST_id; DELETE FROM ORDERS WHERE CUSTOMERID=@CUST_id; DELETE FROM ORDERDETAILS WHERE ORDERID=@orderID "
Dim objCMD As New SqlCommand(strDelete, oConn)
objCMD.Parameters.Add("@CUST_id", id)

I want to reset my application and delete all the data in all tables.
But I have question for this.
1. I do not know how to loop over all the tables and delete data.

Please give me a idea.

OK, this is a big problem, with multiple tables, but here goes. Here's my schema:
--------------------------------------------------
Events
--------------------------------------------------
ID | E_Title
--------------------------------------------------
--------------------------------------------------
EventOptionGroups
--------------------------------------------------
ID | EOG_EventID | EOG_OptionGroupID
--------------------------------------------------
--------------------------------------------------
OptionGroups
--------------------------------------------------
ID | OG_Title
--------------------------------------------------
--------------------------------------------------
Options
--------------------------------------------------
ID | O_OptionGroupID
--------------------------------------------------
--------------------------------------------------
EventRegistration
--------------------------------------------------
ID | ER_EventID
--------------------------------------------------
--------------------------------------------------
RegistrantOptions
--------------------------------------------------
ID | RO_EventRegistrationID | RO_OptionGroupID
--------------------------------------------------
OK, what I'm trying to do is, when I delete an event, I need to delete all the data associated with that event. So here's the thought process.
Delete Event based on ID
Delete all EventRegistration where ER_EventID = Event.ID
Delete all RegistrantOptions where RO_EventRegistrationID = EventRegistration.ID
Delete all EventOptionGroups where EOG_EventID = Event.ID
Delete all OptionGroups where OptionGroups.ID = EOG_OptionGroupID
Delete all Options where O_OptionGroupID = OptionGroups.ID
Sorry that it's so complicated, by I need help. There are foreign key constraints on the tables as well, so you have to work from the bottom back up.

Hello,
I have the following problem:
2 tables: both have the same pk values.
one table must be deleted based on a filter (I mean the table is not delete completely but only some records), I would like to delete same records in the second table.
for ex:
table 1: pk: 1,2,3,4,5
table 2: pk: 1,2,3,4,5
table 1: deleting 1,2, 3 thus also in table 2 pk: 1,2,3 must be deleted.
At the and of process Table1 and Table2 must have the same records (always also in the case of failure, errors and so on ).
The target is avoid using triggers.
OUTPUT is not useful because it writes what is deleted (or may be useful but how to use it?).
How can I do?
Thank

Hi,
Im pretty new to SQL Server, but was able to create a dsn conenction to our dbf database, and then use sql script to import the table into sql server using this script below:
use cameodata;
/* Drop stock Table */
IF EXISTS (
SELECT 1
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'stock'
AND TABLE_SCHEMA = 'dbo'
AND TABLE_TYPE = 'BASE TABLE'
)
BEGIN
DROP TABLE stock
END
/* Import stock Table */
select * into stock
from openrowset ('msdasql','dsn=stock',
'select * from stock')
So basically everytime i run this script, it deletes the table in sql server and then imports the latest copy.
The problem is that this table is huge and it takes a while. What Id rather have is a script that i could run that would compare the dsn connected table with the table currently on sql server and if there are any updates then update sql server, if there are items on the sql server that are not the the latest copy, then delete that record on the sql server table and also if there are new items on the lastest copy then add the new record to the sql server table.
Is this possible?
thanks,
Anthony.
i'm in a bit of a bind at work. if anyone could help, i'd greatlyappreciate it.i have a web app connecting to a sql server using sql serverauthentication. let's say, for example, my login/password isdbUser/dbUser. the web app however, is using windows authentication.so if I am logged into the network as 'DOMAINEric', when I access myweb app, my web app knows that I am 'DOMAINEric'. but to the sqlserver db, I am user 'dbUser'.now, i for each table i have, i need to implement an audit table torecord all updates, inserts, deletes that occur against it. i wasgoing to do so with triggers. this is all fine for selects, inserts,and updates. for each table, i have an updatedby and an updatedate.for example, let's say i have a table:create table blah(id int,col1 varchar(10),updatedby varchar(30),updatedate datetime)and corresponding audit table:create audit_blah(id int,blah_id int,blah_col1 varchar(10),blah_updatedby varchar(1),blah_updatedate datetime)for update and insert triggers, i can know what to insert into theupdatedby column of audit_blah because it's in a corresponding row inblah. my web app knows what user is accessing the application, andcan insert that name into blah. blah's trigger will then insert thatname into audit_blah.however, in the case of a delete, i'm not passing in an 'updatedby',because i'm deleting. in this situation, how can the trigger knowwhat user is deleting? the db only knows that sql user 'dbUser' isdeleting, but doesn't know that 'dbUser' is deleting on behalf of'DOMAINEric'. is there any way for my app to inform the trigger toaccess my windows identity without having a corresponding row in thetable from which to pull that info?obviously, i could have each of my app's users log into SQL serverthrough Windows authentication; then i could just use SYSTEM_USER.but let's say, for performance's sake, it'd be better for me to useone sql server login. (i believe one user works better for connectionpooling purposes.) is there a way to get around this?(i'm hoping a built-in function exists that solves all my problems.)suggestions? resources?any help would be great appreciated.happy turkeys.Eric
