Exporting data from SQL table to Excel File - How to delete rows before inserting new

Hi,

Question pls. I have an MS SQL local package where it exports data from SQL table to Excel file. My question is, how can I erase all the records in my excel file before i export the new data from SQL table?

What i want is to delete the rows in the destination file before inserting new records.

Note:
I cannot do the drop & recreate table because the users has no permission to do this in the database. Only the DB admin is allowed to drop & create table.

Thanks a lot.

Create a view that limits number of exported rows and use it in DTS package instead of a table.

Good Luck.|||hi iburyak,

just the same, the records are being appended to the excel file. what i want is to delete the rows in the destination file before inserting new records.

thanks.|||Did you create a view that removes unwanted records?
Execute a view on a Server side and make sure this is the data you want to export, don't create a view to select * from table_name it will not correct a problem.

You need to give me more information then just I want to delete records.
It is a wrong approach to load all records and delete on destination side you need to load only necessary records.|||Hi Iburyak,

The Question is... this excel file is getting populated everyday and everyday before porting data to the excel the old data has to be erased and new data filled up.

Any help on that.

Thanks in advance..

kbk|||hi kbk,

that was my first design: i drop then recreate the table and it was working properly. but the problem is, the users are not permitted to drop & create tables in the database (only me & the DB admin are allowed to do this). so what i did was create a temporary table, from this temp table i export the data to excel. is there any other way so i can delete the rows before inserting new?

thanks a lot.|||What i want is to delete the rows in the destination file before inserting new records.

I sugggest delete the worksheet instead of delete all the rows. Then recreate the worksheet later.

1. Create an activeX script as below: -This will remove the worksheet.

Function Main()

Dim srccsvfile
Dim objExcel
Dim objWorkbook, objWorksheet

srccsvfile = "C:\Test.xls"

Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = False
objExcel.displayalerts = False

Set objWorkbook = objExcel.Workbooks.open(srccsvfile)
Set objWorksheet = objWorkbook.WorkSheets("New_Table")
objWorksheet.Activate
objWorksheet.Delete 'this is removing the worksheet instead of rows
objWorkbook.Save 'you must save the change otherwise in trouble

objExcel.Workbooks.Close
Set objWorkbook = Nothing
objExcel.Quit
Set objExcel = Nothing
Main = DTSTaskExecResult_Success
End Function

2. Create Execute SQL task as below: - create the worksheet again
CREATE TABLE `New_Table` (
`OfficePK` VarChar (8) ,
`DealerGroupFK` VarChar (4) ,
`StateManagerGroupFK` VarChar (20) ,
`OfficeType` VarChar (1) ,
`OfficeName` VarChar (255) ,
`OfficeAddress1` VarChar (255) ,
`OfficeAddress2` VarChar (255) ,
`OfficeSuburb` VarChar (255) ,
`OfficeState` VarChar (255) ,
`OfficePostCode` VarChar (255) ,
`OfficeCountry` VarChar (255) ,
`OfficePhone` VarChar (255) ,
`RIOfficeID` VarChar (50) ,
`RIFranchiseName` VarChar (255) ,
`VPServerIP` VarChar (50) ,
`LastReceived` DateTime
)
3. Then use data transform as you are doing now.
Make sure that the destination table name is New_Table and the connection is Excel.|||Hi TerryP,
I'll try this.
Thank you very much. =)sql
