CREATE DOMAIN
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The CREATE DOMAIN statement allows for creating DOMAIN types for use as data types in table columns.
Depending on the dialect, a DOMAIN combines the following features:
- A qualified name
- A base data type
- A
DEFAULTvalue - A
NOT NULLconstraint - A
COLLATION - A set of
CHECKconstraints
Domains can be created in jOOQ using:
// Create a domain on a base type
create.createDomain("d1").as(INTEGER).execute();
// Create a domain on a base type and add a DEFAULT expression
create.createDomain("d2").as(INTEGER).default_(1).execute();
// Create a domain on a base type and add a CHECK constraint
create.createDomain("d3").as(INTEGER).constraints(check(value(INTEGER).gt(0))).execute();
Dialect support
This example using jOOQ:
createDomain("d").as(INTEGER)
Translates to the following dialect specific expressions:
-- AURORA_POSTGRES, H2, HSQLDB, POSTGRES, YUGABYTEDB CREATE DOMAIN d AS int -- FIREBIRD CREATE DOMAIN d AS integer -- ORACLE CREATE DOMAIN d AS number(10) -- SQLSERVER CREATE TYPE d FROM int -- ACCESS, ASE, AURORA_MYSQL, BIGQUERY, COCKROACHDB, DB2, DERBY, DUCKDB, EXASOL, HANA, INFORMIX, MARIADB, MEMSQL, MYSQL, -- REDSHIFT, SNOWFLAKE, SQLDATAWAREHOUSE, SQLITE, SYBASE, TERADATA, TRINO, VERTICA /* UNSUPPORTED */
(These are currently generated with jOOQ 3.19, see #10141), or translate your own on our website
