仅当 ColumnX 被索引键覆盖时,才能获取键范围锁。 示例 以下表和索引用作随后的键范围锁定示例的基础。 范围扫描查询 为了确保范围扫描查询是可序列化的,每次在同一事务中执行的相同查询应返回同样的结果。 其他事务不能在范围扫描查询中插入新行;否则这些插入将成为虚拟插入。 例如,以下查询将使用上图...
列级权限可使用语法 <table_name>(<column _name>) 授予。 例如:SQL 复制 GRANT SELECT ON OBJECT::Customer(CustomerName) TO UserJoe; 表上的 DENY 被列中的 GRANT 替代。 但是,表上的后续 DENY 将删除 GRANT 列。示例本节中的以下示例说明如何检索权限信息。
