SHOW CREATE

The SHOW CREATE shows the CREATE statement for an existing , , , , , or .

Required privileges

The user must have any on the target database, function, table, view, or sequence. To run SHOW CREATE TRIGGER, the user must have any privilege on the table on which the trigger is defined.

Synopsis

Parameters

Parameter	Description
object_name	The name of the database, function, table, view, or sequence for which to show the CREATE statement.
TRIGGER trigger_name ON table_name	Show the CREATE TRIGGER statement for a on the specified table.
ALL TABLES	Show the CREATE statements for all tables, views, and sequences in the current database. This option is intended to provide the statements required to recreate the objects in the current database. As a result, SHOW CREATE ALL TABLES also returns the that add, modify, and validate an object’s . The ALTER statements follow the CREATE statements to guarantee that all objects are added before their references.
ALL SCHEMAS	Show the CREATE statements for all in the current database.
ALL TYPES	Show the CREATE statements for all in the current database.

Response

Field	Description
table_name	The name of the table, view, or sequence.
database_name	The name of the database.
function_name	The name of the function.
trigger_name	The name of the trigger (when running SHOW CREATE TRIGGER).
create_statement	The CREATE statement for the database, function, table, trigger, view, or sequence.

Example

Setup

The following examples use MovR, a fictional vehicle-sharing application, to demonstrate CockroachDB SQL statements. For more information about the MovR example application and dataset, see .

To follow along, run with the and flags. This command opens an interactive SQL shell to a temporary, multi-node in-memory cluster with the movr database preloaded and set as the .

$ cockroach demo --nodes=6 --demo-locality=region=us-east,zone=us-east-a:region=us-east,zone=us-east-b:region=us-central,zone=us-central-a:region=us-central,zone=us-central-b:region=us-west,zone=us-west-a:region=us-west,zone=us-west-b

Show the CREATE TABLE statement for a table

> CREATE TABLE drivers (
    id UUID NOT NULL,
    city STRING NOT NULL,
    name STRING,
    dl STRING UNIQUE,
    address STRING,
    CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC)
);

> SHOW CREATE TABLE drivers;

-------------+-----------------------------------------------------------
  drivers    | CREATE TABLE public.drivers (
             |     id UUID NOT NULL,
             |     city STRING NOT NULL,
             |     name STRING NULL,
             |     dl STRING NULL,
             |     address STRING NULL,

             |     UNIQUE INDEX drivers_dl_key (dl ASC)
             | )
(1 row)

To return just the create_statement value:

> WITH x AS (SHOW CREATE TABLE drivers) SELECT create_statement FROM x;

                      create_statement
------------------------------------------------------------
  CREATE TABLE public.drivers (
      id UUID NOT NULL,

      address STRING NULL,
      CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC),
      UNIQUE INDEX drivers_dl_key (dl ASC)
  )
(1 row)

SHOW CREATE TABLE also lists any partitions and defined on primary and secondary indexes of a table. If partitions are defined, but no zones are configured, the SHOW CREATE TABLE output includes a warning.

Show the CREATE TABLE statement for a table with a hidden column

If one or more columns is within a table, SHOW CREATE will display the NOT VISIBLE flag after those columns.

Start by setting the credit_card field to NOT VISIBLE:

> ALTER TABLE public.users ALTER COLUMN credit_card SET NOT VISIBLE;

> SHOW CREATE TABLE users;

table_name   |                      create_statement
-------------+--------------------------------------------------------------
users        | CREATE TABLE public.users (

-----------------------------------------------------------------------------------------
  CREATE VIEW public.user_view (city, name) AS SELECT city, name FROM movr.public.users
(1 row)

Show just a view’s SELECT statement

To get just a view’s SELECT statement, you can query the views table in the built-in information_schema database and filter on the view name:

> SELECT view_definition
  FROM information_schema.views
  WHERE table_name = 'user_view';

              view_definition
--------------------------------------------
  SELECT city, name FROM movr.public.users
(1 row)

Show the CREATE TABLE statement for a table with a multi-region locality

Use the SHOW CREATE TABLE command to view table localities.

To add the first region to the database, or to set an already-added region as the primary region, use a statement:

> ALTER DATABASE movr SET PRIMARY REGION "us-east";

ALTER DATABASE PRIMARY REGION

Time: 49ms total (execution 48ms / network 0ms)

All tables will be in us-east by default. Configure the users table to be instead:

> ALTER TABLE users SET LOCALITY REGIONAL BY ROW;

> SHOW CREATE TABLE users;

  RETURNS TRIGGER AS $$
  BEGIN
    RAISE NOTICE 'Current timestamp: %', now();
    RETURN NEW;
  END;
  $$ LANGUAGE PLpgSQL;

Suppose that you have a multi-region cluster, and you want to return the SHOW CREATE DATABASE statement for a .

In a new terminal, start a virtual multi-region demo cluster:

$ cockroach demo --global --nodes 9

In the SQL shell, :

> ALTER DATABASE movr PRIMARY REGION "us-east1";
ALTER DATABASE movr ADD REGION "europe-west1";
ALTER DATABASE movr ADD REGION "us-west1";

The SHOW CREATE DATABASE output includes the database regions.
