Shows the steps to export table data from your Autonomous Database to Directory as XML data by specifying a query.

1. Connect to your Autonomous Database instance.

   See Connect to Autonomous Database for more information.

2. Create a directory.

   For example:

   CREATE DIRECTORY export_dir AS 'export_dir';

   See Create Directory in Autonomous Database for more information.
3. Run DBMS_CLOUD.EXPORT_DATA and specify the format parameter type with the value json to export the results as XML files to a directory. Do not include the credential parameter when sending output to a directory.

   BEGIN
    DBMS_CLOUD.EXPORT_DATA(
       file_uri_list => 'export_dir:sales.csv',
       format => JSON_OBJECT('type' value 'csv'),
       query => 'SELECT * FROM sales'
    );
   END;
   /
   

   The directory name is case-sensitive when the directory name is enclosed in double quotes. For example:

   BEGIN
    DBMS_CLOUD.EXPORT_DATA(
       file_uri_list => '"export_dir":sales.xml',
       format => JSON_OBJECT('type' value 'xml'),
       query => 'SELECT * FROM sales'
    );
   END;
   /
   

   For detailed information about the parameters, see EXPORT_DATA Procedure.

   For detailed information about the available format parameters you can use with DBMS_CLOUD.EXPORT_DATA, see DBMS_CLOUD Package Format Options for EXPORT_DATA.

   The parameters are:

   • file_uri_list: is a comma delimited list of the export file(s). Use of wildcard and substitution characters is not supported in the file_uri_list.

   • format: specifies the required type parameter. The valid values are datapump, json, xml, csv and parquet and it also optionally defines the options you can specify for the export with the ORACLE_DATAPUMP Access Driver.

   • query: specifies a SELECT statement so that only the required data is exported. The query determines the contents of the dump file(s).

   Note
   
   The DBMS_CLOUD.EXPORT_DATA procedure creates the dump file(s) that you specify in the file_uri_list. The procedure does not overwrite files. If a dump file in the file_uri_list exists, DBMS_CLOUD.EXPORT_DATA generates another file with a unique name. DBMS_CLOUD.EXPORT_DATA does not create directories.

   For detailed information about the parameters, see EXPORT_DATA Procedure.
