SQL Agent job fails to execute

I run my package in the server, it worked fine but when I used to run its in SQL Agent job, it failed to execute.

This sort of thing is commonly down to 32/64 bit issues. You may be developing in BIDS which recognises the 32bit ODBC driver and then you are deploying to a 64bit version of SQL Server.

You can try enabling the 32 bit runtime for your Agent job step or making sure you have the correct versions of the appropriate drivers installed and configured.
