See If Data Exists, Then Execute A SSIS Package, Else Do Nothing

Hi

I need to create a trigger that whenever there is data found in a certain table it must execute a SSIS package. If there is a process in SSIS or a way to manipulate the process to check if there is data and then schedule the package that would also help.

What i've done:

I have an SSIS package that searches for data in a table, copies the data into a flat file and places the file onto a FTP server, which it then renames the file so that the server will accept the flat file once it's in a specific folder, after that it moves the data from the current table to a stage table and truncates the current table.

The Problem:

When there is no data in the table, it creates a 0 bytes file that it puts onto the FTP server which messes things up on that side. All i want to do is put a check on the package to see if there is data before it executes.

Any help or even the slightest bit of information would be of great help.

Kind Regards
