| |
| <p> |
| The <codeph>ALTER DATABASE</codeph> statement changes the characteristics of a database. |
| </p> |
| |
| <p> |
| Use the <codeph>SET OWNER</codeph> clause to transfer the ownership of the database from |
| the current owner to another user or a role. |
| </p> |
| |
| <p> |
| The database owner is originally set to the user who creates the database. When object |
| ownership is enabled in Sentry, an owner of a database can have the <codeph>ALL</codeph> |
| with <codeph>GRANT</codeph> or <codeph>ALL</codeph> without <codeph>GRANT</codeph> |
| privilege. The term <codeph>OWNER</codeph> is used to differentiate between the |
| <codeph>ALL</codeph> privilege that is explicitly granted via the <codeph>GRANT</codeph> |
| statement and a privilege that is implicitly granted by the <codeph>CREATE |
| DATABASE</codeph> statement. |
