Grant Role Syntax¶

GRANT ROLE <role_type> ON <space> TO <user>

The GRANT statement assigns role to Nebula Graph user account. To use GRANT, you must have the GRANT privilege.

Currently, there are five roles in Nebula Graph: GOD, ADMIN, DBA, USER and GUEST.

Normally, first use CREATE USER to create an account then use GRANT to define its privileges (assume you have the CREATE and GRANT privilege). Each role and user account to be granted must exist, or errors will occur.

The <space> clause must be specified as an existed graph space or an error will occur.
