__construct
Constructor.
| Parameters | |
|---|---|
| Name | Description |
data |
array
Optional. Data for populating the Message object. |
↳ name |
string
The name of the table constraint. |
↳ type |
string
Type of constraint, for example unique, primary key, foreign key (currently only primary key is supported). |
↳ table_columns |
array
Table columns used as part of the Constraint, for example primary key constraint should list the columns which constitutes the key. |
↳ custom_features |
Google\Protobuf\Struct
Custom engine specific features. |
↳ reference_columns |
array
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. |
↳ reference_table |
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_name |
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. |
getName
