Using exp for automatic backup on the InternetArticleThere is no such thing as how to effectively analyze the backed up files. Today, we found a tool to parse the files backed up by dump.
This is the DDL wizard.
Note: This tool only supports dump files under rows = N, that is, it can only parse the table structure, view, and stored procedure of dump,Unable to view Data.
In addition to viewing the structure in the dump file, DDL wizard can also gene
