Hello All, i have 2 files in excel which i am uploading them to a folder which is located in the root directory. then i am importing these two files into a sqldatabase. i needed some help in importing them and i got it from my previous post at http://forums.asp.net/t/1261155.aspx but now i have a problem. the import works perfectly first time but when i do it the second time i am getting an error on of the file (header). to explain clearly, what i am doing is , every time i upload a new file , i am deleting the data from the tables, so the new data can be inserted ( basically trying to achieve overwirting the existing data). now this technique works fine with the Detail table but not with the Header table. i think the reason is the header table has a primary key on OrderID and a relationship does exists between the Header and Detail. now how would i overcome this error. can some one please guide me. I really appreciate it.here is my code: // connection for header file protected OleDbCommand headExcelConnection() { // Connect to the Excel Spreadsheet string headConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Server.MapPath("~/imports/headerorder.xls") + ";" + "Extended Properties=Excel 8.0;"; // create your excel connection object using the connection string OleDbConnection headXConn = new OleDbConnection(headConnStr); headXConn.Open(); // use a SQL Select command to retrieve the data from the Excel Spreadsheet // the "table name" is the name of the worksheet within the spreadsheet // in this case, the worksheet name is "Sheet1" and is expressed as: [Sheet1$]

On my aspx Web page, I want to delete a member from database table 'tblMember', but if this MemberID is used as FK in another table, I want to display a user friendlier message like "You cannot delete this member, ....." I am using Try, Catch blocks in my Web Page.
Currently it display this message: "DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_..._....' The conflict occurred in database '...', table 'tblMembers', column 'MemberID'. The statement has been terminated. "
So how should I precisely trap this error? Does anybody know what Exception is it? or what error number in SQL server?
I would like to delete a row in a table, but I get the following message :
The DELETE statement conflicted with the REFERENCE constraint "FK_cs_Users". The conflict occurred in database "mytable", table "dbo.cs_UserProfile", column 'UserID'. The statement has been terminated. (0.701 sec)
But I did this :
alter table cs_Users disable trigger ALL
delete from cs_Users where MembershipID = 'xxx'
Thank you very much for any help to get this work !
Hello Friends How are you?? Friends i am getting problem in SQL Server 2005. I am deployng web application on production server as well as Databse also.

Hi, I am new to MS SQL Server; as I know Access, MYSQL. I made a form though which I want to insert data to SQL SERVER 2005 Database but i during submission I get the below problem, can any one help.
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'

Hi there, I have a stored procedure which i pass a number of parameters into. One of these parameters is staffNo (only passed this in because i couldn't execute the query without it). The thing is this field can be Null, but when trying to pass null into it it comes up with an Foreign Key conflict. staffNo is a foreign key within the table i'm inserting the data into. This is the error i get: "INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'PropStaffFK'. The conflict occurred in database 'DewMountain', table 'TblStaff', column 'staffNo'. The statement has been terminated. The 'PropertyAdvert' procedure attempted to return a status of NULL, which is not allowed. A status of 0 will be returned instead. "
Does anyone know of away around this? how to pass a null value to the stored procedure without it causing this error. Thank you Melanie
Hi all,While using ACCESS and asp for years, I have just had to move my site onto a new server and the opportunity to move my 50MB access DB to msSQL was too good an opportunity to pass up! I used the Migration tools from MS and the data migrated nicely, I can do everything that I used to be able to do on the forum, except when a new user signs up or a member tries to edit their profile, the following error message comes up: Microsoft OLE DB Provider for ODBC Drivers error '80040e14' [Microsoft][ODBC SQL Server Driver][SQL Server]The UPDATE statement conflicted with the CHECK constraint "SSMA_CC$PORTAL_MEMBERS$M_ICQ$disallow_zero_length". The conflict occurred in database "DATABASENAME", table "dbo.PORTAL_MEMBERS", column 'M_ICQ'.
I have checked the database and the dbo.PORTAL_MEMBERS table and except for the autoincrement number, uname and pwrd, everything else is set to accept nulls.
I also went though and filled in everything on the form then I could update.
the same error applies when signing up - the only difference is the name of the table
I then tried to change the data straight in the table by opening it in Server Management Studio Express and got the same error if I did not fill in everything. This tells me that it is not the code, much to my relief!
So I am figuring that there is something somewhere in the DB that I have to change? could someone point me in the right direction - and as I am VERY NEW to this database system, and do not know my way around (it took me about 10 minutes to figure out how to open a table! *LOL*) very clear instructions would be appreciated.

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 Regards Lynn

Could You please tell me what am I missing here ? Thanks a lot.
I am getting this error occasionally on my multi-user web app with the data stored in SQL Server. The key is an identity field incremented by 1 - like Access autonumber. It seems that when two people are writing to the table at the same time they try and use the same key. I didn't think this could happen in sql server ?
It is a one to many table situation and the error occurs in the one table
What is the solution please.

Hi, I don't know if this is possible, i believe not, so I'm here to ask the experts if is possible to have a foreign key constraint that references the key of one of two tables. Like this: I have 3 tables: TABLE X, TABLE A and TABLE B Is it possible to the FK on TABLE X refernce the PK of TABLE A OR TABLE B? If yes, how can I do this? If not, I need to have a fourth table, so TABLE X references TABLE A and TABLE Y references TABLE B. Thanks!
INSERT INTO PRODUCT_SALES (Salesmanid,Productid) VALUES (1,1) INSERT INTO PRODUCT_SALES (Salesmanid,Productid) VALUES (1,2) INSERT INTO PRODUCT_SALES (Salesmanid,Productid) VALUES (1,3)
SELECT * FROM PRODUCT_SALES
/* SalesmanID is reference key from Sales Master and ProductID is reference key from Product Master. How should i restrict user through DB with any constraint check, if user tries to enter
INSERT INTO PRODUCT_SALES (Salesmanid,Productid) VALUES (1,2),
It should throw error , if possible user defined message would be more useful.
how can i implement delete constraint? i mean i don't want the rows of the primary key table to be deleted if they are used as foreign key in some other table. so i want to check if that PK is used as foreign key in other tables before deleting.
Can somebody tell me about on delete constraint and where should it be used - table having foriegn key?
coz want i want is- the moment i delete the data from the table whose primary key is been referenced as foreign key , The Data in all the tables where its primary key is beeen used as forein key should be deleted.
In SQL Server 2005, I hava a client where I do not have access to their SQL Server. I update the database structure by giving them scripts which they run. As I update the structures I occasionally need to delete a constraint, then typically recreate it later. Usually I use this type of snippet:
IF EXISTS (SELECT * FROM sys.default_constraints WHERE object_id = OBJECT_ID(N'[dbo].[ConstraintName]') AND parent_object_id = OBJECT_ID(N'[dbo].[tablename]')) ALTER TABLE [dbo].[tablename] DROP CONSTRAINT [ConstraintName]
This assumes I know the constraint name. A lot of the older constraints have random type names which I assume are different on their server than mine; they were not explicitly given names when created, so they would heve been given names by SQL Server.
Is there a way to delete a constraint without knowing its name? For example, delete all constraints associated with a field, or all constraints ssociated with a table?
Management Studio is an option, but for my client that involves a higher degree of paperwork and permission seeking than just running a script.

 I have a table named [New Item] and created a default constraint on a column, and i wanted to change the data type of the column using the query
alter table [new item] alter column pcs_qty decimal(15,2) not null
but the name of the default constraint is 'DF__New Item__Pcs_Qt__2D12A970' and i am not able to delete the constraint because it contains a space in between.Is there any work around for this.
I tried to delete the constraint by using the query
alter table [new item] drop constraint 'DF__New Item__Pcs_Qt__2D12A970'
but I am getting the exception,
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near 'DF__New Item__Pcs_Qt__2D12A970'.
I am not sure if this is necessarily a simple question, but I'm somewhat new to SQL so I thought maybe there's an obvious answer I just don't know about.
The problem is that I have one "master" table, and a child table that has two foreign key references back to that master table. Both of these foreign key constraints are marked as "on delete cascade" with the intention that should a row from the master table be deleted, any rows that reference that object in EITHER foreign key field should be deleted.
I am wondering why this causes a cycle. It seems logical enough to me, it just involves two passes of the table, one for each affected column.
I am trying to take a value from at textbox and insert into a database. I think I need to convert the text to an integer - but I keep getting an error message saying I'm not allowed to use column names. Basically, I need to figure out how to take user input from these tet boxes and insert them into a database. Any ideas would be welcomed. the exact error is at the bottom the code.Here is the code:Imports System.DataImports System.Data.SqlClientPartial Class County_ConversionTest Inherits System.Web.UI.Page Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim v1 As Integer Dim v2 As Integer 'Dim v3 As Integer v1 = Integer.Parse(TextBox1.Text) v2 = Integer.Parse(TextBox2.Text) TextBox3.Text = (v1 + v2) End Sub Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click Dim strconn As String = "Data Source=.SQLEXPRESS;AttachDbFilename=C:InetpubwwwrootHCBSApp_DataDivAging_Data.MDF;Integrated Security=True;Connect Timeout=30;User Instance=True" Dim cnnDivAging As SqlConnection = New SqlConnection(strconn) Dim v1 As Integer Dim v2 As Integer Dim v3 As Integer v1 = CInt(TextBox1.Text) v2 = CInt(TextBox2.Text) v3 = CInt(TextBox3.Text) Dim strsql As String = "INSERT INTO tblTest (Name, fv1,fv2,fv3)" + _ "Values ('George',v1,v2,v3)" Dim cmdUpdates As SqlCommand = New SqlCommand(strSQL, cnnDivAging) cmdUpdates.Connection = cnnDivAging cnnDivAging.Open() cmdUpdates.CommandType = CommandType.Text cmdUpdates.ExecuteNonQuery() cnnDivAging.Close() End SubEnd ClassHere is the error message -

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 trying to update rows in a simple table that has a UNIQUE KEY CONSTRAINT defined on one of its columns. Here is the DDL for the table:
CREATE TABLE [dbo].[SEC_USER]( Â [SEC_USER_ID] [int] IDENTITY(1,1) NOT NULL, Â [USER_CODE] [varchar](100) NOT NULL, Â [USER_NAME] [varchar](128) NOT NULL, Â [EMP_CODE] [varchar](6) NOT NULL,
[Code] ....
When trying to execute the UPDATE statement the query fails with a constraint violation error:
Violation of UNIQUE KEY constraint 'UQ__SEC_USER__A039F1EE62FE8444'. Cannot insert duplicate key in object 'dbo.SEC_USER'. The duplicate key value is (34337).
What has me baffled is that I'm not doing any insert. Also, the value that it's referencing - 34337 - doesn't exist in the table at all. I'd rather not drop the constraint.
