EXPORT_TABLES

Generates a SQL script that can be used to recreate a logical schema—schemas, tables, constraints, and views—on another cluster.

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

The SQL script conforms to the following requirements:

  • Only includes objects to which the user has access.

  • Orders CREATE statements according to object dependencies so they can be recreated in the correct sequence. For example, if a table references a named sequence, a CREATE SEQUENCE statement precedes the CREATE TABLE statement. Similarly, a table's CREATE ACCESS POLICY statement follows the table's CREATE TABLE statement.

This is a meta-function. You must call meta-functions in a top-level SELECT statement.

Behavior type

Volatile

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
