i am having problem running a simple delete statement against a table. it just hangs is there anything i should look at? the table has 4 primary keys and the index makes up of the 4 keys and ideas?
i viewed the delete statement with the execusion plan and this is what i saw.
delete -> index delete/delete -> sorting the input -> table delete/delete -> Top -> Index scan.
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
View 5 Replies View RelatedHi all.I have used a SqlDataSource in my page with this delete command:DELETE FROM tblPersonnel WHERE (ID = @original_ID)and the "OldValueParameterFormatSring" property of the datasource is "original_{0}".and i also have a GridView and a button for delete in rows.(it's CommandName is "Delete"). But when i try to delete a record, the record does not get deleted and this button only makes a PostBack on the page! Why doesn't it work?
Thanks in advance.
I have the following delete trigger but it doesn't work.
ALTER TRIGGER Users_DeleteUsers
ON dbo.Users
FOR DELETE
AS
DELETE FROM InstantForum_Members WHERE MemberID IN (SELECT ForumMemberId from Deleted)
DELETE FROM InstantKB_Users WHERE UserID IN (SELECT KBMemberId from Deleted)
But when I delete a user from Users table, I get an error in this trigger saying no commit or rollback given in trigger.
Can someone tell me why this trigger will fail ?
Hi all,
I am writing a test result database in SQL 2K5 and one of the features I want to implement is a stored procedure that deletes the oldrecords while preserving a set number of records, the following is what my SP looks like
Procedure [dbo].[CleanResults]
@RecsToKeep bigInt,
@Output Int output
as
Declare @Date Datetime
Declare @Count bigint
set @Date = getdate()
Select @Count = Count(UniqueID) from [Main]
Print 'THE COUNT IS'
print @Count
if ( @Count > @RecsToKeep) begin
set @Count= @Count - @RecsToKeep
Print 'THE Number to delete is'
print @Count
select TOP(@Count) UniqueID from Main order By [Main].[TestDateTime] desc
Delete from [Main] where exists (select TOP(@Count) * from Main order By [Main].[TestDateTime] desc);
set @Output = @Count
end
else begin
set @Output = -1
end
whats odd is that the select staement will evaluate correctly and return the oldest record @Count record, however the delete stament removes all the records. An advice would be appriciated.
Thanks Christopher
PS Any advice for using TOP with variables in MSDE 2k (as opposed to 2k5) would be appreciated

I have 3 tables, with this relation:
tblChats.WebsiteID = tblWebsite.ID
tblWebsite.AccountID = tblAccount.ID
I need to delete rows within tblChats where tblChats.StartTime - GETDATE() < 180 and where they are apart of @AccountID. I have this select statement that works fine, but I am having trouble converting it to a delete statement:
SELECT * FROM tblChats c
LEFT JOIN tblWebsites sites ON sites.ID = c.WebsiteID
LEFT JOIN tblAccounts accounts on accounts.ID = sites.AccountID
WHERE accounts.ID = 16 AND GETDATE() - c.StartTime > 180
I'm using SQL Server 2005 (product version = 9.00.1406.00, product level = RTM, and edition = Developer Edition). I have a db with a number of tables; I created a Foreign Key in one table and added a Foreign Key w/ ON DELETE CASCADE to it -- all using Microsoft SQL Server Management Studio. When I delete the record in the table with the foreign key, the record in the other table does not get deleted. I tried doing this with a simple SQL script in Microsoft SQL Server Management Studio and in a simple .Net / ADO (C#-based) program. Only the record in the table that I'm specifically deleting is deleted.
Here's the table that is referenced by the foreign key (I told Server Management Studio to write out the script):
USE [CHNOPSDb]
GO
/****** Object: Table [dbo].[tblDeviceContainer] Script Date: 08/13/2007 16:47:03 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[tblDeviceContainer](
[ID] [int] IDENTITY(1,1) NOT NULL,
[DeviceContainerTypeID] [int] NOT NULL,
CONSTRAINT [PK_tblDeviceContainer] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
Here's the table that has the foreign key to the above table (again, I told Management Studio to write out the script):
USE [CHNOPSDb]
GO
/****** Object: Table [dbo].[tblNode] Script Date: 08/13/2007 16:46:40 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[tblNode](
[ID] [int] IDENTITY(1,1) NOT NULL,
[NodeName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[NodeTypeID] [int] NOT NULL,
[UnitID] [int] NOT NULL,
[pDeviceContainerID] [int] NOT NULL,
[NodeIndex] [int] NULL,
CONSTRAINT [PK_Node] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
USE [CHNOPSDb]
GO
ALTER TABLE [dbo].[tblNode] WITH CHECK ADD CONSTRAINT [FK_tblNode_tblDeviceContainer] FOREIGN KEY([pDeviceContainerID])
REFERENCES [dbo].[tblDeviceContainer] ([ID])
ON DELETE CASCADE
I then perform a delete using the following:
Use CHNOPSDb;
delete from tblNode where ID = 1;
It deletes the tblNode record but doesn't delete the tblDeviceContainer record that is referenced by tblNode.
Any help?
Thanks,

Hi,
i defined a sqldatasource in VWD manually (option specify sql statement) because several tables are involved. I also need a Delete statement, so i defined it also manually.
The select and delete statement are :
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:test %>" SelectCommand="SELECT aspnet_Users.UserName as lid, aspnet_Roles.RoleName as categorie, aspnet_Users.beheerder as beheerder, aspnet_Membership.Email as emailadres FROM aspnet_Users INNER JOIN aspnet_Membership ON aspnet_Users.UserId = aspnet_Membership.UserId INNER JOIN aspnet_UsersInRoles ON aspnet_Users.UserId = aspnet_UsersInRoles.UserId inner JOIN aspnet_Roles ON aspnet_UsersInRoles.RoleId = aspnet_Roles.RoleId order by username"
DeleteCommand="delete from aspnet_users where userid=@userid"> <DeleteParameters> <asp:Parameter Name="userid" /> </DeleteParameters> </asp:SqlDataSource>
My problem is that the Select works, but not the Delete.
Any idea why?
Thanks

I’m using VB.NET to extract data from an Access database, simple enough. However, I type in the following line:
Sql = "SELECT * FROM [IPAddressList] WHERE [StartIPNo]>=" & IP_Address And "[EndIPNo]<=" & IP_Address
It doesn’t work.
If I type in:
Sql = "SELECT * FROM [IPAddressList] WHERE [StartIPNo]>=" & IP_Address
The above sql line works.
I now realize SQL commands is very sensitive.
FIELD NAMES:
quote:StartIP |EndIP|StartIPNo|EndIPNo|CountryCode
5.0.0.0 |5.163.66.79|83886080|94585423|ZA
5.163.66.80|5.163.66.95|94585424|94585439|SE
5.163.66.96|5.255.255.255|94585440|100663295|ZA
If the user types in a value, I want it to check the values between the StartIPNo and EndIPNo and return the CountryCode.
Any help would be appreciated

If any of you can tell me how the following SQL SELECT statement works , I will be forever grateful! What I mean is, if anyone has actually seen an SQL statement like this and knows what it does, I would be eternally grateful, because I have been writing SQL for over 10 years, and not only do I have no clue how this monstrosity works (and I assure you that it does work), I have never seen anything quite like it. The primary purpose of the code is to sort the chapel messages (mp3s) for my institutions website, but it moonlights for NASA as any code they deem necessary to perform the most complicated computerized tasks known to mankind.

Hi,I have a database stored in MS SQL 2000 and an application written inVB5, which connects the database via JET/ODBC.I have a problem with the UNION statement.When I run a simple query like:"SELECT field1 FROM table1 UNION SELECT field2 FROM table2"I get the following error:"Runtime error 3078 - The Microsoft Jet database engine cannot find theinput table or query 'select field1 from table1'. Make sure it existsand that its name is spelled correctly."I can run the queries separately "SELECT field1 FROM table1" and "SELECTfield1 FROM table2", so that I'm sure table and field names are correctand I have permission to access them.Both field1 and field2 are the same type (int).If I run the query in MS SQL Query Analyzer, it works fine.It doesn't work only when I run it from VB/JET/ODBC.Has anyone already had this kind of problem?Any help will be highly appreciated!Thank you so much for the attention.--Posted via http://dbforums.com

As you can see it should return castedValue as integer but it cast to datetime which is wrong. If I commented line
Code Block
when me.ElementTypeId =4 then cast(mev.ElementValue as datetime)
it casts everything normal, but as soon as it has more than one condition in CASE it will choose anything but not right casting
Looks like I am missing something really fundamental. Any help is apreciated !

In the following t-sql 2012 merge statement, the insert statement works but the update statement does not work. I know that is true since I looked at the results of the update statement:
Merge TST.dbo.LockCombination AS LKC1

from
[LockerPopulation] A

[Code] ...
Thus can you show me some t-sql 2012 that I can use to make update statement work in the merge function?
Hi,I would like to delete a record from a table on the condition that a corresponding ID is located in another table, ie. deleting an email message if the user ID is listed as a recipient in a recipient table etc. Here is my SQL statement: DELETE FROM id_email_message WHERE (id_message IN (SELECT id_message FROM recipients
WHERE id_user = 324) AND message.id_message_status = 2) OR (id_message IN
(SELECT id_message FROM message WHERE id_owner = 324 and id_message_status = 2)) The problem is the multiple select statements paired with the delete statement is too much overhead for the server and I always get a timeout server error (at least that's what I'm guessing, the error page and tracing isn't much helpful). Is there a more efficient way to do this?Thanks.Eitan
Hello there... I'm creating a ASP.net Web Application and storing all my data in SQL database.I'm trying to create a Stored Procedure to Delete info from a table:- I have 3 tables: A, B and C: A's primary key is aID and has no foreign key B's primary key is bID and has 1 foreign key: aID (linking this table to table A); C's primary key is cID and has 1 foreign key: bID (linking this table to table B);- As you can see, all 3 tables are linked (A to B and B to C)I want to be able to DELETE all info from C only by giving aID, is this possible in SQL? I can retrieve the info easily through a SELECT statement and using an INNER JOIN (*). I also know how to do solve this by coding it in C# but I'd have to create some unnecessary variables and more than 1 Stored Procedure when it's probably possible to do all in one!* SELECT cID FROM C INNER JOIN B ON B.bID = C.bIDWHERE A.aID= whateverIf anyone knows the solution to my problem, please don't hesitate :p Thanks,SuperJB
View 2 Replies View Relatedhi, i want to delete some records from my table if there is more then 150 records (it should always be max 150records, it can be less and then it shouldent delete anything),
so when it goes over to 151 records i want to delete the oldest record, so i get the new record + 149 old records, is there a simple way to do this?
When does the DELETE statement physically deletes the records? For example, if I execute the DELETE statement and in the middle of the execution I understand that it is wrong. What will happen if I stop it? Will it delete the records partially? I think the deletion happens when the full statement is done but need an expert answer. Thank you.

Hi, I was handed an old application written for sql05, it has this (kind of) statement:
Dim CommandText As String = "SELECT c.name FROM db1 c LEFT JOIN "
CommandText += "db2.dbo.Users u ON u.iKey = c.key "
CommandText += "WHERE u.cUserName = '" & User & "'"
As you can see, there are two databases, db1 and db2 and this worked fine in sql05, but when I convert each of the databases to sqlexpress, I get this error: Invalid object name 'db2.dbo.Users'.
So how can I make this work in sqlexpress? Are queries across databases not allowed?
Thanks so much for your help!
Hello
I am trying to delete a row from one table and I expected it to also be removed from the subsequent child tables, linked via foreign and primary keys.
However, when I tried to delete a row in the first table I saw this error:
DELETE FROM [dbo].[Names_DB]WHERE [LName_Name]=N'andrews'
Error: Query(1/1) DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_LName_Name'. The conflict occurred in database 'MainDB', table 'Category_A', column 'LName_Name'.
I went to the very last table in the sequence and I was able to delete the row without problems, but it did not effect any of the other tables.
Please advise.
I need to make many changes in these tables, should I use a trigger instead, if so what is the code to trigger each table? I am new to triggers.
Thanks

Lynn

Hey guys...
I am trying to tidy up my code a bit and have one SQL command (Sub class) to call when needing to insert, update, delete and select.
I have got one class I am testing with that delete from a table support_ticket and then calls RunSQL() again to delete the corresponding tickets in Support_Reply.
however it only seems to want to delete from one table at a time...as i commented out the first sql and it worked and the second fires...but if the first one is active it doesnt fire.
Do anyone on the forum know why this has happened?
Sub DeleteUserTicket(sender as Object, e as EventArgs)
Dim strSQL1 = "DELETE FROM Support_Ticket WHERE (TicketID = " & txtticketID & ")"
RunSQL(strSQL1)
strSQL1 = "DELETE FROM Support_Reply WHERE (TicketID = " & txtticketID & ")"
RunSQL(strSQL1)
End Sub
'One class to run the sql statements for the entire page this will reduce in repetitve code as well as reduce code size
Sub RunSQL(strSQL)
Dim objCmd As SqlCommand
Dim sqlConn = New SqlConnection(strConn)
objCmd = New SQLCommand(strSQL, sqlConn)
objCmd.Connection.Open()
'Check that the rows can be deleted if not then return a error.

Jack
