Delete Rows While Table Is Shown On DataGrid
Oct 2, 2007
Hi All,
I have a program which shows some manipulate data from 2 tables on a datagrid.
I'm using another program to delete rows from both tables. (The second program activate from the PC using the RAPI dll).
I have sometimes a problem deleting records.
Actually the Datagrid is not suppose to be shown when the user use the second program, but since I'm not able to determine whether my first program is still running or not, is there an option to force the delete even if other program is using it?
If not, is there a way to stop the first program?
Thanks in advance

Hi,
I have data that is grouped by a code number. One of the code numbers have over 600 rows, while other code numbers have around 10 to 20 rows within it.
When I run the report the code number that has over 600 rows gets split over 2 pages while the other code numbers each get their own page.
How do I make it so that when I run the report the code number that has over 600 rows gets all displayed on the 1 page instead of being split over 2?
Thanks
Ben.

I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.
Here is a basic breakdown of what I am trying to do:
Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)
Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)
I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.
Code:
SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x
This did not seem to do what I needed, it did not delete any rows at all.
I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2
Then I tried another scenerio that I also needed to do:
Code:
SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'
'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.
Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.
Any ideas on what I am doing wrong here?

Hello,
I need to delete rows from one table that appear in another table.
For example:
newnames has fname, lname, age
oldnames has fname, lname, age
So, I want to be able to remove the rows from newname where there are rows in oldnames. This should be simple enough.
This is what I'm trying to use but it is deleting everything from oldnames.
delete from oldname
select * from newnames

I'm a bit new to SQL, so this might be a very simple question, but I was not able to find an answer by search:
I got two tables, with a 1:n relation between them, seller and article, and I want to delete all sellers that do not offer any articles anymore.
An extract of my SQL to show the tables and the relation:
@"CREATE TABLE dbo.[Seller]
(
[ID] uniqueidentifier NOT NULL ROWGUIDCOL CONSTRAINT [PK_Seller] PRIMARY KEY,
) ON [PRIMARY]",
@"CREATE TABLE dbo.[Article]
(
[ID] uniqueidentifier NOT NULL ROWGUIDCOL CONSTRAINT [PK_Article] PRIMARY KEY,
[SellerID] uniqueidentifier NOT NULL,
) ON [PRIMARY]",
@"ALTER TABLE dbo.[Article] ADD CONSTRAINT [FK_ArticleSeller] FOREIGN KEY
(
[SellerID]
) REFERENCES dbo.[Seller]
(
[ID]
)",
Now say I got two sellers (1 & 2), and only one article (1, offered by seller 1). The delete query should delete seller 2 because he is not offering articles anymore.
This probably is dead simple in SQL, something like
DELETE FROM seller WHERE COUNT(article.SellerID=seller.ID)==0
but honestly, my SQL books leave me guessing here, and I found no online ref for cases like this.
Maybe someone can help me here?
Thanks in advance,
Sam

I have a table with more than 1000 records. The columns look like this
Import id | Reference | Date | Username | Filename
Some of the rows are duplicates except for the fact that they have different values for the first column alone (import id)
11111 test 21-07-2015 xxxxxx yyyyyy
22222 test 21-07-2015 xxxxxx yyyyyy

Hi Guys!
This SQL statement, though carefully written to delete only selected rows, deletes the entire A_Shift_Times table:
DELETE FROM A_Shift_Times
WHERE EXISTS (
SELECT 1
FROM
Users
WHERE
(A_Shift_Times.time_in >= CONVERT(DATETIME, '2000-05-29 00:00:00', 102)) AND
((Users.User_Password LIKE N'mrr%') OR (Users.User_Password LIKE N'work%')))
What gives? What am I doing wrong here?

Hello I am new to SSIS and learning as I go. Any guidance to my questions would be appreciated.
I wrote a script that takes the current date and subtracts a number of days/months from this date. I then attempted to use an SQL Task as a select with a parameter using the calculated date from the script. I was not successful in doing this. While performing searches on the WEB with the hopes of finding a solution I came upon the following text in the Microsoft forum under EXECUTE SQL TASK.
When you use an OLE DB Connection Manager, you cannot use parameterized subqueries because the Execute SQL task cannot derive parameter information through the OLE DB provider. However, you can use an expression to concatenate the parameter values into the query string and to set the SqlStatementSource property of the task.
Having come upon this statement I moved on to putting together an OLE DB SOURCE with a Flat File Destination. The SQL that I wrote is:
SELECT BP_ID, INVC_NBR, INVC_DT, BUS_ADD_DT
FROM DW.CUST_SALE_ADDR
WHERE (BUS_ADD_DT = ?)
The flat file destination was mainly used to confirm the select.
Having confirmed my select, I changed the select in the OLE DB SOURCE as follows:
DELETE FROM DW.CUST_SALE_ADDR
WHERE (BUS_ADD_DT = ?)
I also removed the Flat File Destination. Needless to say when I tried to run the package I did not get very far as a package validation error was encountered since there were no output columns.
Can you share how I should go about peforming the delete as described from the table based on a calculated date? And am I not understanding the comment regarding the SQL Statement and the use of parameters?
Thank you and God Bless.

I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.
What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.

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 ran the following query in Query Analyzer on a machine running SQL Server 2000. I'm attempting to delete from a linked server running SQL Server 2005:
DELETE FROM sql2005.production.dbo.products
WHERE vendor='Foo'
AND productId NOT IN
(
SELECT productId FROM sql2000.staging.dbo.fooProductList
)
The status message (and @@ROWCOUNT) told me 8 rows were affected, but nothing was actually deleted; when I ran a SELECT with the same criteria as the DELETE, all 8 rows are still there. So, once more I tried the DELETE command. This time it told me 7 rows were affected; when I ran the SELECT again, 5 of the rows were still there. Finally, after running this exact same DELETE query 5 times, I was able to remove all 8 rows. Each time it would tell me that a different number of rows had been deleted, and in no case was that number accurate.
I've never seen anything like this before. Neither of the tables involved were undergoing any other changes. There's no replication going on, or anything else that should introduce any delays. And I run queries like this all day, involving every thinkable combination of 2000 and 2005 servers, that don't give me any trouble.
Does anyone have suggestions on what might cause this sort of behavior?

Ok here goes. I have 3 tables, one holds case info, the 2nd holds possible outcome on the charges, and they're joined on a 3rd table (CaseOutComes). With me so far? Easy stuff, now for the hard part.
Since there's a very common possiblitly that the Case has multiple charges, we need to track those, and therefore, display them on a datagrid or some other control. I want the user to be able to edit the info and have X number of dropdowns pertaining to how many ever charges are on the case. I can get the query to return the rows no sweat, but ...merging them into 1 record (1 row) with mutiple drops is seeming impossible -- I thought about using a placeholder and added the controls that way, but it was not in agreement with what I was trying to tell it .
Any ideas on how to attack this?

This is my case. I want in my datagrid to display first record from table A and second record from table B. This is because i need to display a price in the column where it will have current price and history price, therefore the first row will be current price and second row will be history price.
This is the output that i trying to do.
Item | Price
-------|---------
A | 2.50 --------> Table A
A | 1.50 --------> Table B
Please let me know if my explanation is not details enough.
Thanks
