37.63. view_column_usage #
视图 view_column_usage 会标识视图的查询表达式中使用的所有列(定义该视图的 SELECT 语句)。仅当包含该列的表由当前启用的角色拥有时,该列才会被包括在内。
The view view_column_usage identifies all columns that are used in the query expression of a view (the SELECT statement that defines the view). A column is only included if the table that contains the column is owned by a currently enabled role.
Note
系统表的列不包括在内。这应该在一段时间内修复。
Columns of system tables are not included. This should be fixed sometime.
