MySQL Information Schema  /  The INFORMATION_SCHEMA ROLE_COLUMN_GRANTS Table

Chapter 25 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 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.
