Creating an UltraLite database from an XML file

Use XML as an intermediate format for managing your UltraLite database.

Prérequis

UltraLite cannot use an arbitrary XML file. The %SQLANY16%\Bin32 and %SQLANY16%\Bin64 directories contains a usm.xsd file, containing the schema definition. Use this file to review the XML format.

Contexte et remarques

You can use XML to:

  • Load data into a new database with a different set of database properties/options.

  • Upgrade the schema from a database created by a previous version of UltraLite.

  • Create a text version of your UltraLite database.

 Task

  1. Save the XML file to a directory of your choosing. You can either:

    • Export/unload a database to an XML file. If you are unloading a SQL Anywhere database, use any of the supported export methods.

    • Take XML output from another source—that source could be another relational database or even a web site where transactions are recorded to a file. You must always ensure that the format of the XML meets the UltraLite requirements.

  2. Run the ulload utility, including any necessary options.

Résultat

The database is created.

Suivant

You can now connect to the database and build tables and other database objects.

Exemple

To create a new UltraLite database in the file sample.udb from the table formats and data in sample.xml, run the following command: 

ulload -c DBF=sample.udb sample.xml
