This wont work because of scope issues. The array $arr[..] is declared in the shell, so it has to be interpreted by the shell. When you try to send it into sqsh's STDIN it won't be able to expand it since at that time the shell has no idea what value the SQL variable @foo will have.
One way of solving this (very ugly, but I have seen it in the wild) is to write some SQL code which generates some ksh code which (yes I said it was gawdugly) creates SQL code.
Don't do this. It might work but someone is going to have to maintain it. Prolly you.
Instead ask yourself why you are using an array in ksh in the first place. Could you use a file? A table in the DB? Is the data available from the inside of a SQL session?
