DataSource Controls :: List Duplicate Records And Group By Clause?

May 27, 2010

I have some duplication that I need to clean up. I wrote a SQL query that is supposed to return duplicate customers who are located in the same city and zipcode.

I have 2 questions regarding it:

1. Is the query syntax correct to find duplicate records by same city and zipcode, data is being returned but it just returns the same customer a few times?

2. I only need to do the GROUP BY clause for Fullname and City however it gives an error when the other columns are left out. The error is Address, State and Zip not being in the aggregate function or in the group by clause.

Adding all the remaining columns to the GROUP BY clause works.

Query is as below:

DataSource Controls :: Clause Criteria Eliminating Records In Outer Join Query?

Feb 15, 2010

I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.

It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.

Here is the query....how do I include the where clause criteria but still include all accounts?

select distinct
bat.acct_id,
isnull(max(isnull(crt.pymt_priority, 0)), 0)[code].....

DataSource Controls :: Deal With Insertion Of Duplicate Records?

Jun 10, 2010

I need to write a sql script which will scan for records in a table (Table1) and thencopy the records found into a second table (Table2). Table2 has the same table structureas Table1Table 1 has a primary Key for the first column named CustIdI thought this would involve A simple sql statement like:

INSERT INTO Table2
FROM Table1
SELECT *

However I just realized that if A record already exists in Table2 and I try to inserta duplicate record into Table2, how should this be handled?Should I instead use an Update statement without a where clause?

Forms Data Controls :: Delete One Duplicate Record Of Many Duplicate Records

Mar 15, 2010

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.

I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:

I used the following query to load in duplicate records:

SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))

ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006

What is the query to delete single duplicate record instead of deleting all duplicate records?
