You do not mention your database version.
In any case, if you are using Oracle7.x you are limited to 254 columns/table so 800 won't work.
If you are using 7.3 of Oracle, then there are 2 dbms_sql.parse calls. One takes a single varchar, the other takes an array of varchars. the array of varchars lets you break the statement up into a whole bunch of smaller strings that will be glued back together for execution -- this allows you to pass in very large (>32k) sql statements in one call. this was first available with 7.3.
If you are using 8.0 of Oracle then use the dbms_sql call with an array of varchar2 and you can create a table with upto 1,000 columns.
