SSIS oledb command error

I have used  oledb command  many time in sevral packages for type one/two updates and inserts. I am running into a strange problem when i use alias to table name in a updates statement. It errors out at the alias name

Error: "Invalid object name 'aliasname' "

example: UPDATE A SET COLUMN1 = ?,COLUMN2 = ? FROM TABLENAME A WHERE COLUMN3 = ?

Is it the way SSIS OLEDB Command works or is the somethng that I am missing???

Started it thinking its a minute job and still digging into it :)

Any help
