sql SELECT MIN(YourTinyIntColumn) AS MinValue, MAX(YourTinyIntColumn) AS MaxValue FROM YourTable; 这个查询将返回 YourTinyIntColumn 列中的最小值和最大值,这可以帮助你验证该列中的实际数据是否超出了 TINYINT 的定义范围。但在大多数情况下,你不需要这样做,因为 TINYINT 的取值范围是固定的。
但是,bigint用于某些特殊的情况,当整数值超过int数据类型支持的范围时,就可以采用bigint。在 SQL Server 中,int数据类型是主要的整数数据类型。 在数据类型优先次序表中,bigint位于smallmoney和int之间。 只有当参数表达式是bigint数据类型时,函数才返回bigint。SQL Server 不会自动将其它整数数据类型(tinyint、smalli...
