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 MovR: A Global Vehicle-sharing App.
To follow along, run cockroach demo to start a temporary, in-memory cluster with the movr dataset preloaded:
$ cockroach demo
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;
table_name | create_statement
+------------+----------------------------------------------------------+
drivers | CREATE TABLE drivers (
| id UUID NOT NULL,
| city STRING NOT NULL,
| name STRING NULL,
| dl STRING NULL,
| address STRING NULL,
| CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC),
| UNIQUE INDEX drivers_dl_key (dl ASC),
| FAMILY "primary" (id, city, name, dl, address)
| )
(1 row)
SHOW CREATE TABLE also lists any partitions and zone configurations 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 VIEW statement for a view
> CREATE VIEW user_view (city, name) AS SELECT city, name FROM users;
> SHOW CREATE user_view;
table_name | create_statement
+------------+--------------------------------------------------------------------------------+
user_view | CREATE VIEW 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 SEQUENCE statement for a sequence
> CREATE SEQUENCE desc_customer_list START -1 INCREMENT -2;
> SHOW CREATE desc_customer_list;
table_name | create_statement
+--------------------+----------------------------------------------------------------------------------------------------+
desc_customer_list | CREATE SEQUENCE desc_customer_list MINVALUE -9223372036854775808 MAXVALUE -1 INCREMENT -2 START -1
(1 row)
