28.3.27 The INFORMATION_SCHEMA ROLE_COLUMN_GRANTS Table

The ROLE_COLUMN_GRANTS table (available as of MySQL 8.0.19) provides information about the column privileges for roles that are available to or granted by the currently enabled roles.

The ROLE_COLUMN_GRANTS table has these columns:

• GRANTOR

  The user name part of the account that granted the role.

• GRANTOR_HOST

  The host name part of the account that granted the role.

• GRANTEE

  The user name part of the account to which the role is granted.

• GRANTEE_HOST

  The host name part of the account to which the role is granted.

• TABLE_CATALOG

  The name of the catalog to which the role applies. This value is always def.

• TABLE_SCHEMA

  The name of the schema (database) to which the role applies.

• TABLE_NAME

  The name of the table to which the role applies.

• COLUMN_NAME

  The name of the column to which the role applies.

• PRIVILEGE_TYPE

  The privilege granted. The value can be any privilege that can be granted at the column level; see Section 15.7.1.6, “GRANT Statement”. Each row lists a single privilege, so there is one row per column privilege held by the grantee.

• IS_GRANTABLE

  YES or NO, depending on whether the role is grantable to other accounts.
