When you get this Oracle database error message …

Error message: Caused By: java.sql.SQLSyntaxErrorException: ORA-01792: maximum number of columns in a table or view is 1000

This may be a solution for you …

There is a workaround … set the “_fix_control” parameter to ‘17376322:OFF‘.

You can use one of the following statements to set the parameter:

alter session set "_fix_control" = '17376322:OFF';

or

alter system set "_fix_control" = '17376322:OFF';
