When PostgreSQL returns a RowDescription for a domain type, the type OID is the base type's (so fetching a domain type over text returns a RowDescription for text). However, when a composite type is returned, the type OID there is that of the domain, so we provide "clean" support for domain types.

Constructors

PostgresDomainType(string, string, uint, PostgresType, bool)

Constructs a representation of a PostgreSQL domain data type.

protected PostgresDomainType(string ns, string name, uint oid, PostgresType baseType, bool notNull)

Parameters

ns string

name string

oid uint

baseType PostgresType

notNull bool

Properties

BaseType

The PostgreSQL data type of the base type, i.e. the type this domain is based on.

public PostgresType BaseType { get; }

Property Value

PostgresType

NotNull

True if the domain has a NOT NULL constraint, otherwise false.

public bool NotNull { get; }
