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.
2. the database have database diagram so threre are dependency with tables so the delete order is hard to decide.
I have created two table with same data structure. I need realtime effects (i.e. data) on both tables - Table1 & Table2.
Following Points to Consider.
1. Both tables are in the same database.
2. Table1 is using for data entry & I wants the same data in the Table2.
3. If any row insert, update & delete occers on Table1, the same effect should be done on Table2.
4. I need real time data insert, update & delete on Table2.
I knew that using triggers it could be possible, I have successfully created a trigger for inserting new rows (using logical table "Inserted") in Table2 but not succeed for update & delete yet.
I want to understand how can I impletement this successfully without any ambiguity.
I have attached data structure for tables. Thanx...
I've a table named Master in which a column is referenced in other tables like Child1, Child2,.. ChildN. I've deleted a part of data( say Column Id values 1,2,3,4,5) from all the Child tables which pointed to Master table Id column.
Now, I want to delete the same Id values from Master table as there rows are not referred in any of the child tables. When I try to delete the Id values 1 thru 5 from Master table, it is scanning all child tables for the references and taking lot of time for the deletion.
Is there any way to specify to the system(in the query) to delete the Master table values without scanning the child tables..?
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'
this is my Delete Query NO 1 alter table ZT_Master disable trigger All Delete ZT_Master WHERE TDateTime> = DATEADD(month,DATEDIFF(month,0,getdate())-(select Keepmonths from ZT_KeepMonths where id =1),0) AND TDateTime< DATEADD(month,DATEDIFF(month,0,getdate()),0) alter table ZT_Master enable trigger All
I have troble in Delete Query No 2 here is a select statemnt , I need to delete them select d.* from ZT_Master m, ZT_Detail d where (m.Prikey=d.MasterKey) And m.TDateTime> = DATEADD(month,DATEDIFF(month,0,getdate())-(select Keepmonths from ZT_KeepMonths where id =1),0) AND m.TDateTime< DATEADD(month,DATEDIFF(month,0,getdate()),0) I tried modified it as below delete d.* from ZT_Master m, ZT_Detail d where (m.Prikey=d.MasterKey) And m.TDateTime> = DATEADD(month,DATEDIFF(month,0,getdate())-(select Keepmonths from ZT_KeepMonths where id =1),0) AND m.TDateTime< DATEADD(month,DATEDIFF(month,0,getdate()),0) but this doesn't works..
can you please help? and can I combine these 2 SQL Query into one Sql Query? thank you

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

I have 2 tables "Orders" and "OrderProducts" In my application, there are moments when I clean up these tables. There is a query that looks for some flag in the "Orders" table, and deletes the records. But there are related (PK-FK) records in the "OrderProducts" table. How can I delete also these records in the same query?
I've set up a grid control on my other page and trying to delete items via a check box. I got it to work with deleting from one table but I need to delete from two tables at the same time. How do I code using a stored procedure called Delete Resource instead of the "Delete from Titles where ...(code is below) Now if I can add my other table called resources to the sql query that's fine as they both will use titleID to delete the info.Any help would be appreciated.

I am converting all the inline sql in my ASP.NET app to stored procs and I am experiencing some difficultly with my shortest and least complex stored proc. I am new to both ASP.NET and SQL especially using stored procedures so this may have some extremely obvious flaw in it. I am trying to delete a entry that has parts in two tables. I created a stored procedure along the lines of: CREATE PROCEDURE DeleteEntry(Â Â Â Â Â @EntryIDINT)ASDELETE FROM firstTable WHERE entry_id = @EntryIDDELETE FROM secondTable WHERE entry_id = @EntryIDI have a remove button on a asp page that executes the stored procedure but it only removes the entry from the second table the first time I click it and then when I click it a second time it removes the entry from the first table.
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) objCMD.Parameters.Add("@orderID", LBLORDER.Text) oConn.Open() objCMD.ExecuteNonQuery() oConn.Close()
I get the following error: DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_Orders_Customers'. The conflict occurred in database 'Store', table 'Orders', column 'CustomerID'. DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_OrderDetails_Orders'. The conflict occurred in database 'Store', table 'OrderDetails', column 'OrderID'. The statement has been terminated. The statement has been terminated
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.
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.
I have 30 or 40 tables in a database called Temp with names like PV_ and i am trying to figure out how to loop through and delete them. I've searched all over the web and forums looking for an answer but can't seem to find it. Does anyone know how to delete tables with the keyword like?
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?).
