SQL The data types ntext and varchar are incompatible in the not equal to operator 错误 在SQL中,需要判断标题和文本内容为空(不是null ''与null是有区别的). 如果直接 通过 字段<>'' 会报上面的错误提示, 正确的判断方法为 CONVERT(NVARCHAR(4000),[名称])<>'' 因为NTEXT不能直接和VARCHAR比较. 实际...

Operator 用于声明支持数据表字段的聚合计算(原子指标),如 sum、count、max 等,同时 operator 也支持配置成多个聚合计算的二次运算表达式(复合指标),比如在计算人均类指标时,其复合指标表达式为总值 / 人数。 Dimension 用于声明查询的分组维度,同时也支持虚拟列,其声明块的每个元素含义与 Metric 声明块相同。
