GRANT USER Statement (grant_user_statement)

The GRANT USER statement (grant_user_statement) grants another database user the owner privilege that the database system administrator (SYSDBA user) or a database administrator (DBA user) has over a database user.

Syntax

<grant_user_statement> ::= GRANT USER <granted_users> [FROM <user_name>] TO <user_name>

<granted_users> ::= <user_name>,...| *

Explanation

The current user must be a database administrator (DBA user).

The user names specified after the FROM and TO keywords must be different and must identify DBA users. If FROM <user_name> is not specified, the current database user is assumed implicitly.

The database users specified after the GRANT USER keywords must exist and must not be a member of a user group. They must have the user class RESOURCE user or STANDARD user. The FROM user must have the owner privilege for these database users. If * is specified, the GRANT USER statement affects all database users for which the FROM user has the owner privilege.

The FROM user grants the TO user the owner authorization which the FROM user has over the specified database users. These rights are revoked from the FROM user. In particular, the TO user is granted the right to drop any specified database user and to alter the user class and other properties of this user.
