Overview

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

Instance Attribute Summary

• #custom_features ⇒ ::Google::Protobuf::Struct

  Custom engine specific features.

• #name ⇒ ::String

  The name of the table constraint.

• #reference_columns ⇒ ::Array<::String>

  Reference columns which may be associated with the constraint.

• #reference_table ⇒ ::String

  Reference table which may be associated with the constraint.

• #table_columns ⇒ ::Array<::String>

  Table columns used as part of the Constraint, for example primary key constraint should list the columns which constitutes the key.

• #table_name ⇒ ::String

  Table which is associated with the constraint.

• #type ⇒ ::String

  Type of constraint, for example unique, primary key, foreign key (currently only primary key is supported).

Instance Attribute Details

#custom_features ⇒ ::Google::Protobuf::Struct

Returns Custom engine specific features.

Returns:

• (::Google::Protobuf::Struct) —

  Custom engine specific features.

end

#name ⇒ ::String

Returns The name of the table constraint.

Returns:

• (::String) —

  The name of the table constraint.

  extend ::Google::Protobuf::MessageExts::ClassMethods
end

#reference_columns ⇒ ::Array<::String>

Returns 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.

Returns:

• (::Array<::String>) —

  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.

end

#reference_table ⇒ ::String

Returns 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.

Returns:

• (::String) —

  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.

#table_columns ⇒ ::Array<::String>

Returns Table columns used as part of the Constraint, for example primary key constraint should list the columns which constitutes the key.

Returns:

• (::Array<::String>) —

  Table columns used as part of the Constraint, for example primary key constraint should list the columns which constitutes the key.

end

#table_name ⇒ ::String

Returns 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.

Returns:

• (::String) —

  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.
