SQL Query to delete duplicate records

Hey Guys...
There was a small logical check missed in my automated blog(KuwaitFresh.com). And because of this there occured duplicate records which means duplicate posts! which will be not be accepted by any user :) Here is the query to delete duplicate records in your table...

List Duplicate Rows:

SELECT Field,Count(*)

FROM TABLE

GROUP BY FIELD

HAVING ( COUNT(*) > 1 )

DELETE duplicate Rows:

General Syntax:

DELETE FROM TABLENAME WHERE POSTID in

(SELECT T1.POSTID

from TABLENAME T1, TABLENAME T2

where T1.DUPLICATEFIELD = T2. DUPLICATEFIELD

and T1. UNIQUEFIELD > T2.UNIQUEFIELD)

Example:

DELETE FROM TABLENAME WHERE POSTID in

(SELECT T1.POSTID

from TABLENAME T1, TABLENAME T2

where T1.TITLE = T2.TITLE

and T1.POSTID > T2.POSTID)

Hope It is Helpful :-)

Execute a parameterised EXE dynamically inside SSIS

Hi Reader....

We had a requirement to run a same application for different POS(Point of sale) The challenge is to create a single application that takes parameters Store number as input parameter and does the required operation. Doing so we can use the same applicaiton any number of stores. In SSIS we have the module "Execute Process Task" to exectue exe files. I have given the file location in "Executalbe" property under Process Tab.



Regarding the Parameter, First i tried with 'args[0]' in the EXE Created from DotNet Console Applcaition, tried to use it as input parameters. Unfortunately it did'nt work. When i googled found that we can use Console.ReadLine() and get the required parameters in the EXE file And when you need to execute through SSIS(SQL Server Integration Services), we just need to pass the parameter (User Varaiable in SSIS, Eg: User::VarialbeName) in Standard Input Varaible property under Process.

This will pass the parameter dynamically during execution :-)
