Synonyms |
Supported, with differences. |
The names of Oracle objects in the same namespace must be unique. In GaussDB, the name of a synonym can be the same as that of a table, view, function, or package in the same namespace. In this case, GaussDB preferentially accesses the object with the original name. If the object with the original name is not found, GaussDB searches for the object to which the synonym points. PUBLIC synonyms are searched only when the schema name is a username. |
