问题
I have 10 Million customer numbers in my data base table. I want to run query every time for first 1 million customers and save that data in .csv file. How can I do that with SSIS package? Ex ,
First time:
Select First name, Last name, Customer Id From Customer Where Customer Id between 1 to 1,000,000
Now get the result and store data in test1.csv file on local.
Second time:
Select First name, Last name, Customer Id From Customer Where Customer Id between 1,000,001 to 2,000,000
Now get the result and store data in test2.csv file on local.
Up to 10th times
10 million customer number should be dynamic,,It is not fix, next time it may be 20 millions so, we have to run same query 20 times on database.
Thanks, Sanjay

Here's an algorigthm OTTOMH
Do a rowcount on the table store that into a variable called TotalRows
Divide TotalRows by 20 and store that into a variable called IncrementValue.
Create a FOR LOOP with a variable called RowCounter that goes from from 0 to TotalRows increments by IncrementValue
Create a variable called SelectQuery with evaluate expression set to true, and use the RowCounter and IncrementValue to create the appropriate Select Statement
Create a variable called OutputFileName with evaluate expression set to true, and use the RowCounter and IncrementValue to create a filename
Create a Connection Manager of type FlatFile called OutputFilepath and point it to the desired folder that you want it to write to
In the connection manager's expressions, create a dynamic connection string using the required folder path and the variable FileName
Use a DataFlow inside the for loop and add a OleDB Data Source and a Flat File destination
- OLEDB Data Source query should be a variable, set it to the variable SelectQuery
- point the Flat File Destination to the OutputFilepath
run it
