How To Restrict Tables From Inserting Duplicates
Nov 26, 2007
hi all
I have been posting in VB.NET forum ,but i am new to this forum.
I am working on an application using vast amount of data . So we get data in flatfiles. We used to get data for two or three months in more than three or four flat files .Some time we try to load the same files more than once .So it leads to duplicates in tables
I heard that there is some settings in table , so that it will not allow the same data once it is imported .
if anybody knows about this please help me
thanks & regards

I have the following objective:
1. I want to check a column to see if there are values (to Eliminate dups)
2. Once checked the values in a column, if not found insert the new value
Here is my code for this:
ALTER TRIGGER DUPLICATES ON AMGR_User_Fields_Tbl
-- When inserting or updating
AFTER INSERT, UPDATE AS
-- Declare the variables
DECLARE @AN varchar(200)
[Code] ....

I need to remove duplicate data from around 25 tables. I want to use a while loop to go through all tables. If I list out all of the column names the query runs fine, but since there are 25 tables some with 50 plus columns I was hoping to use something like the following, which errors out because my sub queries return more than one result.
SELECT q.* from
(Select ROW_NUMBER() OVER ( Partition BY (SELECT [name] AS [Name] FROM syscolumns
WHERE id = (SELECT id FROM sysobjects
WHERE type = 'U'
AND [Name] = 'Orders')
)
Order by (select top 1 [name] AS [Name] FROM syscolumns
[Code] ....

INSERT
INTO [Table2Distinct]Â Â Â Â Â Â Â Â

,[ACCIDENT_DATE]
[code]....
I used the above query and it still inserts all the duplicate records. What is wrong with my statement?

Hi
I currently have two tables called Book and JournalPaper, both of which have a column called Publisher. Currently the data in the Publisher column is the Publisher name that is entered straight into either table and has been duplicated in many cases. To tidy this up I have created a new table called Publisher where each entry will have a unique ID.
I now want to remove the Publisher columns from Book and JournalPaper, replace it with an ID foreign key column and move the Publisher name data into the Publisher table. Is there a way I can do this without duplicating the data as some publishers appear several times on both tables?
Any help with this will be greatly appreciated as my limited SQL is not up to this particular challenge!!!
Thanks!

I have 2 tables below:
Table 1:
Product No Quantity
A 1
B 2
C 3
Table 2:
Product No Grade Quantity
A Good
 A Normal
 A Bad
 B Good
 B Bad
 C Good
C Normal
C Bad
In Table 2, Product No divided by Grade. I want to lookup the Quantity from Table 1 to Table 2. The same Product No will have 1 value, the other value is 0. The result for Column Quantity should be like this:
Table 2:
Product No Grade Quantity
A Good 1
A Normal 0
A Bad 0
B Good 2
B Bad 0
C Good 3
C Normal 0
C Bad 0

My basic situation is this - I ONLY want duplicates, so the oppositeof DISTINCT:I have two tables. Ordinarily, Table1ColumnA corresponds in a one toone ratio with Table2ColumnB through a shared variable. So if I queryTableB using the shared variable, there really should only be onrecord returned. In essence, if I run this and return TWO rows, it isvery bad:select * from TableB where SharedVariable = 1234I know how to join the tables on a single record to see if this is thecase with one record, but I need to find out how many, among possiblymillions of records this affects.Every record in Table1ColumnA (and also the shared variable) will beunique. There is another column in Table1 (I'll call itTable1ColumnC) that will be duplicated if the record in Table2 is aduplicate, so I am trying to use that to filter my results in Table1.I am looking to see how many from Table1 map to DUPLICATE instances inTable2.I need to be able to say, in effect, "how many unique records inTable1ColumnA that have a duplicate in Table1ColumnC also have aduplicate in Table2ColumnB?"Thanks if anyone can help!-- aknoch

I'm joining several tables and when I add the last one I get duplicate results. How can I get just one for each?
select a.field, b.field, c.field
from atblname as a inner join btblname as b on a.id = b.parent_id
left outer join ctblname as c on a.id = c.parent_id
There are more than one result when joining tbl a and c, but I'm getting a reult for each of them for all results from joining a and b.

I have a table with 22 million Business records. I can see that there are duplicates when I group by BusinessName and Address and Phone. I'd like to place only the duplicates into a table, with a ranking, oldest business key gets a ranking of 1.
As a bonus I'd like each group to have a distinct group name (although not necessary, just want to know how to do this)
Later after I run more verifications to make sure these are not referenced elsewhere I'll delete everything with a matchRank > 1 out of the main Business table.
DROP TABLE [dbo].[TestBusiness];
GO
CREATE TABLE [dbo].[TestBusiness](
[Business_pk] INT IDENTITY(1,1) NOT NULL,
[BusinessName] VARCHAR (200) NOT NULL,
[Address] VARCHAR(MAX) NOT NULL,
[code]....

I just got started with ASP.NET and SQL Express a few days ago. I have a little bit of SQL (MySQL) experience, but nothing professional. I'm trying to build a toy application just as a refresher for SQL and to learn a few more things.Anyway, I've got two tables:Users:user_id, user_nameRegistration:reg_id, user_id, fname, lname, passwdNow, when someone new registers on the site, I need to update both tables. When I add a user to the Users table, the user_id is autoincremented. I'd like to get that user_id, somehow, so that I can then update the registration table with the correct user_id.What would be the "best" way to do this? SQL query? Stored procedure? Trigger?

Hello all... I'm working on a C++ Windows service that writes to a SQL Server database. I consider myself quite a novice at SQL Server, but I have played around with it over the years... Performance is going to be a concern with this project.
Let's say...
Table A has columns PkA(identity), Stuff(text), FkB (Table B's Pk)
Table B has columns PkB(identity), MoreStuff(text)
I'll be executing SQL statements from my service - INSERTs, etc...
What's the most efficient way to write to these two tables? The immediate challenge I have is getting that PkB value after inserting Table B and using it for Table A's FkB.
Is there a way I can insert into both tables with one SQL statement?
Thanks!! Curt.

Hi, I have two different tables that I want to insert into, i have the code (as below) my only problem is i want to insert a qty into tbl_multi and a different qty into tbl_stock, how do i do this. I have been comfusing myself with it all afternoon, maybe someone can point it out for me int i = 0;
int scount = 0;for (i = 1; i <= 5; i++)
{if (((TextBox)FormView1.FindControl("txtP1_" + i.ToString())).Text != "")
{string sConnMAXID = "Data Source=sql380.mysite4now.com;Initial Catalog=nashdfDB1;User ID=******;Password=******";
SqlConnection objConnOID = new SqlConnection(sConnMAXID);int intStockIDMAX = (Convert.ToInt32(Session["intMAXSID"])) + 1;
int intQtyP1 = Convert.ToInt32(((TextBox)FormView1.FindControl("txtP1_" + i.ToString())).Text);int intLocationP1 = Convert.ToInt32(((DropDownList)FormView1.FindControl("ddlP1_" + i.ToString())).SelectedValue);
scount = intQtyP1 + scount;using (objConnOID)
{
objConnOID.Open();string sqlInsert = "INSERT INTO tbl_stock_multi_location(stock_ID, qty, location) " + "VALUES (@stock_ID, @qty, @location);"; <<<<<<<<<<<<<<<< need to try and add the SQL onto the end here
//INSERT INTO tbl_stock(qty)" +// "SELECT qty AS SQTY FROM tbl_stock VALUES (@SQTY);";
SqlCommand objCmd1 = new SqlCommand(sqlInsert, objConnOID);
objCmd1.Parameters.AddWithValue("@stock_ID", intStockIDMAX);
objCmd1.Parameters.AddWithValue("@qty", intQtyP1);objCmd1.Parameters.AddWithValue("@location", intLocationP1);
// objCmd1.Parameters.AddWithValue("@tbl_stock.qty", scount); <<<<<<< this was the param that i was playing about with
// either will work
// objCmd1.ExecuteNonQuery();
objCmd1.ExecuteScalar();
objConnOID.Close();

Hi all,
I am trying to insert user's input from a web form into the tables. For example,
PURCHASE TABLE(PurchaseID, PurchaseNo, Date, PartID)
PART TABLE(PartID, PartDescription,MachineID)
MACHINE TABLE(MachineID, MachineName)
On the web form I have textboxes for the Purchase No., date and part description, and a drop down list for the machine name. How do I insert them into the different tables?
I've just start learning ASP.NET and I am using Web Matrix for this. The examples I've seen so far only shows how to insert into a single table.
Thanks!

I have a shopping cart app in ASP. I don't want to upload to the DB until the credit card goes through. Once the credit card goes through, I update my tables: Shipping(info), Orders, and Billing(info).
I'm not done yet though. I have to loop though the shopping cart and pass the paramters to an SPROC each time through the loop. If I have three items in the cart, then I need to call the SPROC three times.(let me know if there is a better way to do this)
So I am thinking I will need 2 SPROC's, one for the first three tables, and one for the OrderDetail table. My concern is grabbing the proper foreign key from the Order table. If I use SELECT MAX(id), I may get the wrong ID if someone elses has inserted another row before I grab the proper ID.
I need to figure out how use my second SPROC to grab the proper ID from the Order table, and then insert that record into the OrderDetail table.(Am I being paranoid about another record being inserted? I think this could happen between the execution of my first SPROC and the second one.)
Thanks all

I have been told itcannot be done.If it can be done in one statement, what is that statement?If it cannot be done in one statement, how can it be done in the leastnumber of statements?Thanks,Greg the SQL student

I am currently building an electricity quoting facility on my website. I am trying to insert the data which the user enters into 3 linked tables within my database. My stored procedure therefore, includes 3 inserts, and uses the @@Identity, to retrieve the primary keys from the first 2 inserts and put it as a foreign key into the other table.
When the user comes to the quoting page, they enter their contact details which goes into a client_details table, then they enter the supply details for their electric meter these get inserted into the meter table which is linked to client_details. The supply details which the users enters are used to calculate a price. The calculated price, then gets put into a quote table which is linked to the meter table. This all seems to work fine with my stored procedure.
However I want to be able to allow a user to enter more than one meter supply details and insert this into the meter table, with the same client_id for the foreign key. This will also generate another quote to insert into the quoting table. However I do not know how to get this to work.
Should I be looking at using Sessions and putting a SessionParameter on the client_id for the inserts for these additional meters??

Hi All, am new to sql server in my application I am having one Asp.net web page, the user has to enter values for 5 fields(Empno,Empname,salary,deptno,deptname) in that web page and for that i created two tables in sql serverEmp Table- empno(primary key),empname,salaryDept Table- Deptno(primary key),empno(Foreign key ),Deptname(with some check constraint.) After the user enter all the values in the Asp.net web page now i want to store data into database for that i wrote the following stored procedure...create procedure usp_EmpDept @empno integer, @empname varchar(15), @salary money, @deptno integer, @deptname varchar(10) As Insert into emp(empno,empname,salary)values(@empno,@empname,@salary) Insert into dept(deptno,Empno,deptname)values(@deptno,@empno,@deptname) but the problem is whenever some constaint violation for eg. if some check constraint violation in Dept table its inserting the values in the Emp table only, but my requirement is, It must enter into both tables if there is no constaraint violation otherwise it has to ignore both the tables. And also please suggest is there any better way to insert values into two tables other than using the stored procedure Any help will be greatly appreciated..Thanks,Vision..

i created an SSIS package to look for data in a table on another system and compare it with the table i have in system 2, if there are any changes to system 1 then it must apply them to system 2
My Problem:
It scans through my table and finds all the correct records to insert, but when it has to insert the new data into System 2 table i keep on getting violation and contraint errors because of the primary key and foreign key constraints. how can i get around this, or does anyone have an alternative solution for me.
Total Specification Requirements:
i have 2 systems both running SQL Server. everytime data gets updates in system 1, the same change needs to be made in system 2. The databases and tables are identical.
Any Help would be graetlty appreciated
Kind Regards

Hello everyone, My web application uses SQL Server database and I am connecting via standard SqlConnection object and running stored procedures using SqlCommand object. In one of my page, I have data coming from 2 different tables. Now , data from 1 table comes as only single record. But from other table it comes as multiple records. Meaning, data that I read as 1 record, goes to different textbox and dropdown controls on page. Data that comes in multiple rows, I am binding that data with DataGrid. Now, in aspx page data from both table can be updated and on aspx page I only need to provide a single save button. Now, I am not sure how to save/insert/update a single row in 1 table and multiple rows in another table in 1 transaction. I thought of stored procedure. But I don't think its straightforward with stored procedures since table with multiple records, I am not sure how to pass all the records in stored procedure's arguments.Is there any way that I can control whole transaction in ASP .NET? Thanks,Ujjaval

I am trying to insert into two tables simultaneously from a formview. I read a few posts regarding this, and that is how I've gotten this far. But VWD 2005 won't let me save the following stored procedure. The error I get says “Incorrect syntax near ‘@WIP’. Must declare the scalar variable “@ECReason� and “@WIP�.� I'm probably doing something stupid, but hopefully someone else will be able to save me the days of frustration in finding it. Thanks, the tables and procedures are below.
I made up the two tables just for testing, they are:
tbltest
ECID – int (PK)

Hi guys,I have a problem with my query. What i want to happen is to populate my table EV_NOTIFICATIONDETAILS (Docownerid, CurrentSentDate, LastSentDate, detailsID, GeneralRemarks) using the datas from the two different tables EV_NOTIFICATIONHEADER and EV_DOCDETAILS.I tried to create some a query but im having a error. The problem is once i insert the data from datas to the columns Docownerid, CurrentSentDate, LastSentDate the datas are stored in the database and when i tried to insert the remaining columns TO EV_NOTIFICATIONDETAILS detailsID, GeneralRemarks getting the datas from EV_DOCDETAIL it creates a new set of records in the database. Meaning it doesn't update the records in the table EV_NOTIFICATIONDETAILS but it creates a new set of records.here's my code:INSERT INTO EV_NOTIFICATIONDETAILS (Docownerid, CurrentNoticeSentDate, LastNoticeSentDate) SELECTDocownerid, CurrentSentDate, LastSentDateFROMEV_NOTIFICATIONHEADERINSERT INTO EV_NOTIFICATIONDETAILS (detailsID,GeneralRemarks) SELECTdetailsID,GeneralRemarksFROMEV_DOCDETAIL Any ideas and suggestions will be greatly appreciated.
