具有良好 SQL 的 Reportbuilder 数据集错误？

Question

我有一个bigint 状态，其中设置了按位标志，我正在尝试制作报告以使用此信息，我的代码去了

cast(foo.State & 0x0 as bit)&1 as Case1,
cast(foo.State & 0x1 as bit)&1 as Case2,
cast(foo.State & 0x2 as bit)&1 as Case3,
cast(foo.State & 0x4 as bit)&1 as Case4,
cast(foo.State & 0x8 as bit)&1 as Case5,

但是当我尝试将 2 位组合成一个唯一状态时它失败了，

我试过了：

(cast(foo.State & 0x4 as bit) and cast(foo.State & 0x8 as bit)) as CaseBar

还有

Case foo.State & 0xc when 12 then 1 else 0 end as CaseBar

这两个在 SQL 查询中运行良好，但在 reportbuilder 数据集属性中失败，这里有任何反馈或指针吗？

Answer 1

实现它的方法是：

cast((cast(foo.State & 0x8 as bit) & Cast(foo.State & 0x4 as bit)) as bit)&1 as CaseBar,

问题是报告生成器引擎不支持完整的 TSQL 命令集
