The CREATE TABLE statement creates a new table in a database.

Note:

This statement performs a schema change. For more information about how online schema changes work in CockroachDB, see Online Schema Changes.

Required privileges

The user must have the CREATE privilege on the parent database.

Parameters

Parameter Description
IF NOT EXISTS Create a new table only if a table of the same name does not already exist in the database; if one does exist, do not return an error.

Note that IF NOT EXISTS checks the table name only; it does not check if an existing table has the same columns, indexes, constraints, etc., of the new table.
table_name The name of the table to create, which must be unique within its database and follow these identifier rules. When the parent database is not set as the default, the name must be formatted as database.name.

The UPSERT and INSERT ON CONFLICT statements use a temporary table called excluded to handle uniqueness conflicts during execution. It's therefore not recommended to use the name excluded for any of your tables.
column_def A comma-separated list of column definitions. Each column requires a name/identifier and data type; optionally, a column-level constraint or other column qualification (e.g., computed columns) can be specified. Column names must be unique within the table but can have the same name as indexes or constraints.

Any PRIMARY KEY, UNIQUE, and CHECK constraints defined at the column level are moved to the table-level as part of the table's creation. Use the SHOW CREATE statement to view them at the table level.
index_def An optional, comma-separated list of index definitions. For each index, the column(s) to index must be specified; optionally, a name can be specified. Index names must be unique within the table and follow these identifier rules. See the Create a Table with Secondary Indexes and Inverted Indexes example below.

The CREATE INDEX statement can be used to create an index separate from table creation.
family_def An optional, comma-separated list of column family definitions. Column family names must be unique within the table but can have the same name as columns, constraints, or indexes.

A column family is a group of columns that are stored as a single key-value pair in the underlying key-value store. CockroachDB automatically groups columns into families to ensure efficient storage and performance. However, there are cases when you may want to manually assign columns to families. For more details, see Column Families.
table_constraint An optional, comma-separated list of table-level constraints. Constraint names must be unique within the table but can have the same name as columns, column families, or indexes.
opt_interleave You can potentially optimize query performance by interleaving tables, which changes how CockroachDB stores your data.
opt_partition_by An enterprise-only option that lets you define table partitions at the row level. You can define table partitions by list or by range. See Define Table Partitions for more information.

Table-level replication

By default, tables are created in the default replication zone but can be placed into a specific replication zone. See Create a Replication Zone for a Table for more information.

Row-level replication

CockroachDB allows enterprise users to define table partitions, thus providing row-level control of how and where the data is stored. See Create a Replication Zone for a Table Partition for more information.

Note:
The primary key required for partitioning is different from the conventional primary key. To define the primary key for partitioning, prefix the unique identifier(s) in the primary key with all columns you want to partition and subpartition the table on, in the order in which you want to nest your subpartitions. See Partition using Primary Key for more details.

Examples

Create a table

In this example, we create the users table with a single primary key column defined. In CockroachDB, every table requires a primary key. If one is not explicitly defined, a column called rowid of the type INT is added automatically as the primary key, with the unique_rowid() function used to ensure that new rows always default to unique rowid values. The primary key is automatically indexed.

Note:
Strictly speaking, a primary key's unique index is not created; it is derived from the key(s) under which the data is stored, so it takes no additional space. However, it appears as a normal unique index when using commands like SHOW INDEX.

Create a table with secondary and inverted indexes

In this example, we create secondary and inverted indexes during table creation. Secondary indexes allow efficient access to data with keys other than the primary key. Inverted indexes allow efficient access to the schemaless data in a JSONB column.

Create a table with auto-generated unique row IDs

To auto-generate unique row IDs, use the UUID column with the gen_random_uuid() function as the default value:

copy
icon/buttons/copy
> CREATE TABLE users (
        id UUID NOT NULL DEFAULT gen_random_uuid(),
        city STRING NOT NULL,
        name STRING NULL,
        address STRING NULL,
        credit_card STRING NULL,
        CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC),
        FAMILY "primary" (id, city, name, address, credit_card)
);
copy
icon/buttons/copy
> INSERT INTO users (name, city) VALUES ('Petee', 'new york'), ('Eric', 'seattle'), ('Dan', 'seattle');
copy
icon/buttons/copy
> SELECT * FROM users;
                   id                  |   city   | name  | address | credit_card
+--------------------------------------+----------+-------+---------+-------------+
  cf8ee4e2-cd74-449a-b6e6-a0fb2017baa4 | new york | Petee | NULL    | NULL
  2382564e-702f-42d9-a139-b6df535ae00a | seattle  | Eric  | NULL    | NULL
  7d27e40b-263a-4891-b29b-d59135e55650 | seattle  | Dan   | NULL    | NULL
(3 rows)

Alternatively, you can use the BYTES column with the uuid_v4() function as the default value instead:

copy
icon/buttons/copy
> CREATE TABLE users2 (
        id BYTES DEFAULT uuid_v4(),
        city STRING NOT NULL,
        name STRING NULL,
        address STRING NULL,
        credit_card STRING NULL,
        CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC),
        FAMILY "primary" (id, city, name, address, credit_card)
);
copy
icon/buttons/copy
> INSERT INTO users2 (name, city) VALUES ('Anna', 'new york'), ('Jonah', 'seattle'), ('Terry', 'chicago');
copy
icon/buttons/copy
> SELECT * FROM users;
                        id                       |   city   | name  | address | credit_card
+------------------------------------------------+----------+-------+---------+-------------+
  4\244\277\323/\261M\007\213\275*\0060\346\025z | chicago  | Terry | NULL    | NULL
  \273*t=u.F\010\274f/}\313\332\373a             | new york | Anna  | NULL    | NULL
  \004\\\364nP\024L)\252\364\222r$\274O0         | seattle  | Jonah | NULL    | NULL
(3 rows)

In either case, generated IDs will be 128-bit, large enough for there to be virtually no chance of generating non-unique values. Also, once the table grows beyond a single key-value range (more than 64MB by default), new IDs will be scattered across all of the table's ranges and, therefore, likely across different nodes. This means that multiple nodes will share in the load.

This approach has the disadvantage of creating a primary key that may not be useful in a query directly, which can require a join with another table or a secondary index.

If it is important for generated IDs to be stored in the same key-value range, you can use an integer type with the unique_rowid() function as the default value, either explicitly or via the SERIAL pseudo-type:

copy
icon/buttons/copy
> CREATE TABLE users3 (
        id INT DEFAULT unique_rowid(),
        city STRING NOT NULL,
        name STRING NULL,
        address STRING NULL,
        credit_card STRING NULL,
        CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC),
        FAMILY "primary" (id, city, name, address, credit_card)
);
copy
icon/buttons/copy
> INSERT INTO users3 (name, city) VALUES ('Blake', 'chicago'), ('Hannah', 'seattle'), ('Bobby', 'seattle');
copy
icon/buttons/copy
> SELECT * FROM users3;
          id         |  city   |  name  | address | credit_card
+--------------------+---------+--------+---------+-------------+
  469048192112197633 | chicago | Blake  | NULL    | NULL
  469048192112263169 | seattle | Hannah | NULL    | NULL
  469048192112295937 | seattle | Bobby  | NULL    | NULL
(3 rows)

Upon insert or upsert, the unique_rowid() function generates a default value from the timestamp and ID of the node executing the insert. Such time-ordered values are likely to be globally unique except in cases where a very large number of IDs (100,000+) are generated per node per second. Also, there can be gaps and the order is not completely guaranteed.

Create a table with a foreign key constraint

Foreign key constraints guarantee a column uses only values that already exist in the column it references, which must be from another table. This constraint enforces referential integrity between the two tables.

There are a number of rules that govern foreign keys, but the two most important are:

  • Foreign key columns must be indexed when creating the table using INDEX, PRIMARY KEY, or UNIQUE.

  • Referenced columns must contain only unique values. This means the REFERENCES clause must use exactly the same columns as a primary key or unique constraint.

You can include a foreign key action to specify what happens when a column referenced by a foreign key constraint is updated or deleted. The default actions are ON UPDATE NO ACTION and ON DELETE NO ACTION.

In this example, we use ON DELETE CASCADE (i.e., when row referenced by a foreign key constraint is deleted, all dependent rows are also deleted).

copy
icon/buttons/copy
> CREATE TABLE users (
        id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
        city STRING,
        name STRING,
        address STRING,
        credit_card STRING,
        dl STRING UNIQUE CHECK (LENGTH(dl) < 8)
);

Create a table with a check constraint

In this example, we create the users table, but with some column constraints. One column is the primary key, and another column is given a unique constraint and a check constraint that limits the length of the string. Primary key columns and columns with unique constraints are automatically indexed.

copy

Create a table that mirrors key-value storage

CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. Although it is not possible to access the key-value store directly, you can mirror direct access using a "simple" table of two columns, with one set as the primary key:

> CREATE TABLE kv (k INT PRIMARY KEY, v BYTES);

When such a "simple" table has no indexes or foreign keys, INSERT/UPSERT/UPDATE/DELETE statements translate to key-value operations with minimal overhead (single digit percent slowdowns). For example, the following UPSERT to add or replace a row in the table would translate into a single key-value Put operation:

> UPSERT INTO kv VALUES (1, b'hello')

This SQL table approach also offers you a well-defined query language, a known transaction model, and the flexibility to add more columns to the table if the need arises.

Create a table from a SELECT statement

You can use the CREATE TABLE AS statement to create a new table from the results of a SELECT statement. For example, suppose you have a number of rows of user data in the users table, and you want to create a new table from the subset of users that are located in New York.

copy
icon/buttons/copy

                   id                  |   city   |       name       |           address           | credit_card

Create a table with a computed column

In this example, let's create a simple table with a computed column:

copy
icon/buttons/copy
> CREATE TABLE users (
        id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
        city STRING,
        first_name STRING,
        last_name STRING,
        full_name STRING AS (CONCAT(first_name, ' ', last_name)) STORED,
        address STRING,
        credit_card STRING,
        dl STRING UNIQUE CHECK (LENGTH(dl) < 8)
);

Then, insert a few rows of data:

copy
icon/buttons/copy
> INSERT INTO users (first_name, last_name) VALUES
    ('Lola', 'McDog'),
    ('Carl', 'Kimball'),
    ('Ernie', 'Narayan');
copy
icon/buttons/copy
> SELECT * FROM users;
                   id                  | city | first_name | last_name |   full_name   | address | credit_card |  dl
+--------------------------------------+------+------------+-----------+---------------+---------+-------------+------+
  5740da29-cc0c-47af-921c-b275d21d4c76 | NULL | Ernie      | Narayan   | Ernie Narayan | NULL    | NULL        | NULL
  e7e0b748-9194-4d71-9343-cd65218848f0 | NULL | Lola       | McDog     | Lola McDog    | NULL    | NULL        | NULL
  f00e4715-8ca7-4d5a-8de5-ef1d5d8092f3 | NULL | Carl       | Kimball   | Carl Kimball  | NULL    | NULL        | NULL
(3 rows)

The full_name column is computed from the first_name and last_name columns without the need to define a view.

Create a table with partitions

Note:

The primary key required for partitioning is different from the conventional primary key. To define the primary key for partitioning, prefix the unique identifier(s) in the primary key with all columns you want to partition and subpartition the table on, in the order in which you want to nest your subpartitions. See Partition using Primary Key for more details.

Create a table with partitions by list

In this example, we create a table and define partitions by list.

copy
icon/buttons/copy
> CREATE TABLE rides (
        id UUID NOT NULL,
        city STRING NOT NULL,
        vehicle_city STRING,
        rider_id UUID,
        vehicle_id UUID,
        start_address STRING,
        end_address STRING,
        start_time TIMESTAMP,
        end_time TIMESTAMP,
        revenue DECIMAL(10,2),
        CONSTRAINT "primary" PRIMARY KEY (city ASC, id ASC),
        INDEX rides_auto_index_fk_city_ref_users (city ASC, rider_id ASC),
        INDEX rides_auto_index_fk_vehicle_city_ref_vehicles (vehicle_city ASC, vehicle_id ASC),
        FAMILY "primary" (id, city, vehicle_city, rider_id, vehicle_id, start_address, end_address, start_time, end_time, revenue),
        CONSTRAINT check_vehicle_city_city CHECK (vehicle_city = city))
        PARTITION BY LIST (city)
          (PARTITION new_york VALUES IN ('new york'),
          PARTITION chicago VALUES IN ('chicago'),
          PARTITION seattle VALUES IN ('seattle'));

Create a table with partitions by range

In this example, we create a table and define partitions by range.

copy
icon/buttons/copy
> CREATE TABLE rides (
        id UUID NOT NULL,
        city STRING NOT NULL,
        vehicle_city STRING,
        rider_id UUID,
        vehicle_id UUID,
        start_address STRING,
        end_address STRING,
        start_time TIMESTAMP,
        end_time TIMESTAMP,
        ride_length INTERVAL as (start_time - end_time) STORED,
        revenue DECIMAL(10,2),
        CONSTRAINT "primary" PRIMARY KEY (ride_length ASC, city ASC, id ASC),
        INDEX rides_auto_index_fk_city_ref_users (city ASC, rider_id ASC),
        INDEX rides_auto_index_fk_vehicle_city_ref_vehicles (vehicle_city ASC, vehicle_id ASC),
        FAMILY "primary" (id, city, vehicle_city, rider_id, vehicle_id, start_address, end_address, start_time, end_time, revenue),
        CONSTRAINT check_vehicle_city_city CHECK (vehicle_city = city))
        PARTITION BY RANGE (ride_length)
          (PARTITION short_rides VALUES FROM ('0 seconds') TO ('30 minutes'),
          PARTITION long_rides VALUES FROM ('30 minutes') TO (MAXVALUE));

Show the definition of a table

To show the definition of a table, use the SHOW CREATE statement. The contents of the create_statement column in the response is a string with embedded line breaks that, when echoed, produces formatted output.

copy
icon/buttons/copy
> SHOW CREATE rides;
  table_name |                                                               create_statement
+------------+----------------------------------------------------------------------------------------------------------------------------------------------+
  rides      | CREATE TABLE rides (
             |     id UUID NOT NULL,
             |     city STRING NOT NULL,
             |     vehicle_city STRING NULL,
             |     rider_id UUID NULL,
             |     vehicle_id UUID NULL,
             |     start_address STRING NULL,
             |     end_address STRING NULL,
             |     start_time TIMESTAMP NULL,
             |     end_time TIMESTAMP NULL,
             |     ride_length INTERVAL NOT NULL AS (start_time - end_time) STORED,
             |     revenue DECIMAL(10,2) NULL,
             |     CONSTRAINT "primary" PRIMARY KEY (ride_length ASC, city ASC, id ASC),
             |     INDEX rides_auto_index_fk_city_ref_users (city ASC, rider_id ASC),
             |     INDEX rides_auto_index_fk_vehicle_city_ref_vehicles (vehicle_city ASC, vehicle_id ASC),
             |     FAMILY "primary" (id, city, vehicle_city, rider_id, vehicle_id, start_address, end_address, start_time, end_time, revenue, ride_length),
             |     CONSTRAINT check_vehicle_city_city CHECK (vehicle_city = city)
             | ) PARTITION BY RANGE (ride_length) (
             |     PARTITION short_rides VALUES FROM ('00:00:00') TO ('00:30:00'),
             |     PARTITION long_rides VALUES FROM ('00:30:00') TO (MAXVALUE)
             | )
