Structure

SQLCreateEnum

An expression representing a CREATE TYPE query. Used to create enumeration types.
struct SQLCreateEnum

Overview

CREATE TYPE "name" AS ENUM ('value1', 'value2');

This expression does not check whether the current dialect supports separate enumeration types; users should take care not to use it with incompatible drivers.

Note

As with SQLAlterEnum, the full range of the CREATE TYPE query is not supported by this expression.

See SQLCreateEnumBuilder.
