Methods

decode(String value, int pgType, {String? connectionName}) → Object?

Convert a string recieved from the database into a dart object. Null if it decodes to null, e.g. the json scalar null (a SQL null never gets here).

encode(dynamic value, String? type, {String? connectionName}) → String

Convert an object to a string representation to use in a sql query. Be very careful to escape your strings correctly. If you get this wrong you will introduce a sql injection vulnerability. Consider using the provided encodeString function.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool
