Hasura.Backends.DataConnector.Schema.Table

Synopsis

data Table = Table {
- name :: Name
- columns :: [Column]
- primaryKey :: Maybe Text
- description :: Maybe Text
}

Documentation

data Table Source #

A schematic representation which captures a named collection of columns

TODO(cdparks): schematic in the sense of "relating to a schema" or symbolic? This language is also used in the Column documentation

An element of a table is known as a row, record, tuple, or object, and conforms to the shape specified by the list of Columns below.

cf. https://en.wikipedia.org/wiki/Table_(database) https://www.postgresql.org/docs/13/ddl-basics.html

NOTE(jkachmar): This type shouldn't _need_ ser/de instances, but they're imposed by the Backend class.
