SHOW WARNINGS [LIMIT [offset,] row_count]

like_or_where: {
    LIKE 'pattern'
  | WHERE expr
}

如果给定SHOW 语句的语法包含一部分， 则为可以包含 SQL和 通配符的字符串。该模式对于将语句输出限制为匹配值很有用。 LIKE 'pattern''pattern'%_

一些SHOW语句还接受一个WHERE子句，该子句在指定要显示的行方面提供了更大的灵活性。请参阅 第 26.8 节，“SHOW 语句的扩展”。

在SHOW语句结果中，用户名和主机名使用反引号 (`) 引起来。

许多 MySQL API（例如 PHP）使您能够像对待来自;SHOW的结果集一样对待从语句 返回的结果。SELECT有关详细信息，请参阅 第 29 章连接器和 API或您的 API 文档。此外，您可以在 SQL 中处理对 INFORMATION_SCHEMA数据库中的表进行查询的结果，而这是您无法轻松处理SHOW 语句结果的。请参阅第 26 章，INFORMATION_SCHEMA 表。
