I need to delete records from one table base on criteria from another table. The example below from the Northwind database shows exactly what I want to do. I want to delete the records from the employee table who a terrorityID of 30346 in the EmployeeTerritories table.
Can someone tell me how to write a delete statement that will delete the rows returned from the following SQL Statement? The sql statement will return one employee name. I would lke to delete that one employee from the employee table and I haven’t been able to figure out how to do it.
////////// Sql Statment
SELECT dbo.EmployeeTerritories.EmployeeID, dbo.EmployeeTerritories.TerritoryID
FROM dbo.EmployeeTerritories INNER JOIN
dbo.Employees ON dbo.EmployeeTerritories.EmployeeID = dbo.Employees.EmployeeID
WHERE (dbo.EmployeeTerritories.TerritoryID = N'30346')
////////// end of sql statement
I need to run a DELETE query based on 2 tables. I can't use JOIN with delete queries, so how do I do this?
What I initially tried to do was:
Code:
DELETE FROM tblProductState JOIN tblProduct ON tblProduct.id_Product = tblProductState.id_Product WHERE tblProductState.id_State = 54 AND tblProduct.id_ProductType = 1
Basically, I need to delete FROM tblProductState, WHERE tblProductState.id_State = 54 AND tblProduct.id_ProductType = 1
How can I do this without using JOIN. Use a sub-query? How?
well i have 2 table one name detcom and another entcom stored in DB1 the key for both to join on is lets say A, B, C . I need to check if there are records based on the key A, B, C of both table where C EQUALS to '80_300_113' and if there are delete them and then grab data from another database named DB2 on same server (same instance) wich contains the same tables entcom and detcom and insert all the data from those tables into the same tables in DB1 based on the key and where C = '80_300_113'
What is the logic of the below DELETE statement?It deletes all records where the file_modified column value is smaller then the maximum value in the same column, but not crystal clear how...
delete a from Staging a left join (select max(file_modifieddate) as file_modifieddate from Staging) b on a.file_modifieddate = b.file_modifieddate where b.file_modifieddate is null
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'm using SqlDataSource and an Access database. Let's say I got two tables:user: userID, usernamemessage: userID, messagetextLet's say a user can register on my website, and leave several messages there. I have an admin page where I can select a user and delete all of his messages just by clicking one button.What would be the best (and easiest) way to make this?Here's my suggestion:I have made a "delete query" (with userID as parameter) in MS Access. It deletes all messages of a user when I type in the userID and click ok.Would it be possible to do this on my ASP.net page? If yes, what would the script look like?(yes, it is a newbie question)
I have a table with a large number of records that I need to delete, before attempt to perform the delete I also archived the records to another table.
So I need to delete all of these selected records stored in the archive table from the main table. I can now reference all the records that qualify for the delete in the main table by performing a join on the archive table like so:
select * from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
So all the records check out to be the ones I'd like to perform a delete on but I just can't figure out how to perform a delete of the records with little or no change to the existing query.
Obviously something like this won't work:
delete from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
Though it would be nice if it did.:D
So my question is how would I use the existing query with some modification to delete only the records that this query returns. I've tried selection of records in the main table based on the existing records in the archive table but it can return a higher number of records than what I know is expected. I actually need the join specified to be in place to do it.
In SQL Server 2000/2005 (not CE) I can use the following T-SQL statement to delete orphaned rows from a table:
DELETE GroupsMembers FROM GroupsMembers LEFT OUTER JOIN Groups ON GroupsMembers.GroupID = Groups.ID WHERE Groups.ID IS NULL
SQL Server CE does not seem to support combining the JOIN statement with the DELETE statement. Is this correct? If yes, is there any alternative statement that could be used to accomplish the same thing?
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table. The makeid and orderdate belong to the OrderDetails table. The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
I have 2 tables, I will add sample data to them to help me explain...Table1(Fields: A, B)=====1,One2,Two3,ThreeTable2(Fields: A,B)=====2,deux9,neufI want to create a query that will only return data so long as the key(Field A) is on both tables, if not, return nothing.

Hi I need some help on a query. I need to delete some records from a table, this table has a dependency to another table Table 1: dbo.Accounts and Table 2: dbo.AccountsToUser In the dbo.Accounts table there are AccountId and OwnedByAccountId 54708002 54708001 54708003 54708001 65708002 65708001 65708003 65708001 54708001 2233440165708001 NULL In the dbo.AccountsToUser there are AccountId and UserId 65708002 10065708003 10165708003 10465708003 10654708001 19465708002 199 What I need is to delete every record from dbo.AccountsToUser that has an account connection to an account in the dbo.Accounts that has OwnedByAccount like NULL So in the example above I should delete from dbo.AccountsToUser 65708002 10065708003 10165708003 10465708003 106 Since they are connected to 65708001 which has OwnedByAccountStatus like NULL I could delete the records manually since the table is still hand able, but I need this to be a daily job so all help would be very nice Thanks!

I'm trying to write a script to do the following: delete everything from table1 where column A and B (of table1) does not match column A and B of table2

I am beginner ot SQL Server. I want to know that when we delete a row or a set of Rows from a table, it'll only make the space available for subsequent inserts into it or will the Delete also free the memory used by the table.
Suppose I am inserting customer records in the details table when the customer comes into the system. If i make a logic to delete the customer record from the table and insert into the backup table when it leaves the system(As the data inserted is quite large and my application queries into this table at each transaction). Will it help in optimizing the SQL Queries or it is useless to do so.
I have part of a stored proc that I need help with. I need to figure out how to delete infro from the tblManifest using the @ssnDelete variable. I Have multiple records ffor the given above variable.
Would this need to loop in order to work and that is the solution for this.
I get ther following error when I run the full stored proc. ------------------------------
Msg 512, Level 16, State 1, Line 2
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. ------------------------------
Here is the code fro part of the proceedure. Thanks in advance.

Hi, I'm really not very good at SQL sadly, so would really appreciate any help. I'm basically working on a website that has a chatroom. I want it so the chatroom table only holds, say 15 lines of chat, then once a new line of chat is entered the last line in the table is deleted, so the table always has a maximum of just 15 rows. The fields are: MessageID Poster Message DateTime I've tried my best, but just don't know how to do it. I suppose it's something like: SELECT TOP 15 * FROM Chatroom ORDER BY MessageID DESC - this gives me the last 15 rows. Then I need a delete statement to delete the rest?! Sorry, I am very bad at SQL, so any help would be great. This is written in a stored procedure. Can the stored procedure pick up whether there are 15 or more rows in the table, and if so then delete all bar the newest 15 rows of chat? To summarise: I want a stored procedure that checks if 15 or more rows exist, if they do then delete all bar the newest 15 rows. Thanks, Ricky
We're trying to construct a query that deletes records containing 48 particular phone numbers from a large db. The 48 numbers are the entire contents of a smaller db, in a field of the same name as in the larger db (home_phone). We're using Sequel Server 7.0 and Access 97. The db's are in Access now. We failed in Acess and now would like to import into sql and try it there. Thanks, Tad McArdle
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.
