View Source GoogleApi.DataMigration.V1.Model.ConstraintEntity (google_api_data_migration v0.11.0)

Constraint is not used as an independent entity, it is retrieved as part of another entity such as Table or View.

Attributes

  • customFeatures (type: map(), default: nil) - Custom engine specific features.
  • name (type: String.t, default: nil) - The name of the table constraint.
  • referenceColumns (type: list(String.t), default: nil) - Reference columns which may be associated with the constraint. For example, if the constraint is a FOREIGN_KEY, this represents the list of full names of referenced columns by the foreign key.
  • referenceTable (type: String.t, default: nil) - Reference table which may be associated with the constraint. For example, if the constraint is a FOREIGN_KEY, this represents the list of full name of the referenced table by the foreign key.
  • tableColumns (type: list(String.t), default: nil) - Table columns used as part of the Constraint, for example primary key constraint should list the columns which constitutes the key.
  • tableName (type: String.t, default: nil) - Table which is associated with the constraint. In case the constraint is defined on a table, this field is left empty as this information is stored in parent_name. However, if constraint is defined on a view, this field stores the table name on which the view is defined.
  • type (type: String.t, default: nil) - Type of constraint, for example unique, primary key, foreign key (currently only primary key is supported).
