SYS.EXPORT_DDLS¶

You can use the EXPORT_DDLs system procedure to export table definitions in text format. The EXPORT_DDLs system procedure takes a single argument, exportURI. You can provide any spark supported URI such as s3, local path, or HDFS. All the DDLs such as TABLE, VIEW, DATABASE, FUNCTION, DEPLOY, ALTER, UPDATE, GRANT are exported to a text file in exportURI with the name part-00000. Verify there are respective DDLs in the generated file for all the tables shown on the UI.

Syntax¶

call sys.EXPORT_DDLS('<exportURI>');

Examples¶

call sys.EXPORT_DDLS('/home/xyz/extracted/ddls');
