Using the dbunload utility to export data

The dbunload utility lets you export one, many, or all of the tables in the database. You can export table data, as well as table schemas. If you want to rearrange your tables in the database, you can also use the dbunload utility to create the necessary command files and modify them as needed. You can unload tables with structure only, data only, or with both structure and data.

You can also extract one or many tables with or without command files. These files can be used to create identical tables in different databases.

Note

The dbunload utility is functionally equivalent to the Sybase Central Unload Database Wizard. You can use either one interchangeably to produce the same results.

Use the dbunload utility when you:

  • need to rebuild or extract your database
  • want to export data in text format
  • need to process large amounts of data quickly
  • have flexible file format requirements
