EXPORT_TABLES

Generates a SQL script that can be used to recreate a logical schema—schemas, tables, constraints, and views—on another cluster. EXPORT_OBJECTS only exports objects to which the user has access.

Syntax

EXPORT_TABLES(  '[destination]' [, 'scope' ] )

Parameters

destination

Specifies where to send output, one of the following:

  • An empty string ('') writes the script to standard output.

  • The path and name of a SQL output file. This option is valid only for superusers. If you specify a file that does not exist, the function creates one. If you specify only a file name, Vertica creates it in the catalog directory. If the file already exists, the function silently overwrites its contents.
scope

Specifies one or more tables to export, as follows:

[database.]schema[.table][,…]

If set to an empty string, Vertica exports all non-virtual table objects to which you have access, including table schemas, sequences, and constraints.

If you specify a schema, Vertica exports all non-virtual table objects in that schema.

If you specify a database, it must be the current database.

Privileges

None

Example

See Exporting Tables.

The following example exports to standard output all tables in the store schema:

=> SELECT EXPORT_TABLES('','store');
