Multiple Line SQL for MySQL?

Here is a segment of the handler I use for restoring data to MySQL.
This takes the file produced by mysqldump and re-instates it. tRestore
is a variable containing the text data.
get offset(";" & cr, tRestore)
if it = 0 then exit repeat
put char 1 to it of tRestore into tSQL
delete char 1 to it of tRestore
get doSQLexecute(tSQL, tID)
if it is not a number then
answer error "Error restoring from backup." & cr & it & cr & tSQL
exit to top
I have a doSQLexecute function that is just a wrapper for the
revExecuteSQL command. I realize that you didn't want to have to do
this, but it is really quite fast.
