declare @x xml set @x = '' select @x.query(' distinct-values((1, 1, 2)) ') as result 查詢會傳回 1 2。 實作限制 以下是限制: distinct-values()函式會將整數值對應至 xs:decimal。 distinct-values()函式僅支援先前提及的類型,而且不支援基底類型的混合。
declare @x xml set @x = '' select @x.query(' distinct-values((1, 1, 2)) ') as result 该查询将返回 1 2。 实现限制 限制如下: distinct-values()函数将整数值映射到 xs:decimal。 distinct-values()函数仅支持前面提到的类型,并且不支持基类型的混合体。
