You declare two operands to define a binary operator , and you declare one operand to define a unary operator , including a type conversion operator 声明两个操作数以定义一个二元运算符，声明一个操作数以定义一个一元运算符（包括类型转换运算符） 。
Bitwise operators can be combined with the = sign to unite the operation and assignment : & = , | = and ^ = are all legitimate . ( since ~ is a unary operator it cannot be combined with the = sign 按位运算符可与等号( = )联合使用，以便合并运算及赋值: & = ， | =和^ =都是合法的(由于~是一元运算符，所以不可与=联合使用) 。
If a cube contains a dimension with custom level formulas , and also contains dimensions both before and after it with custom member formulas and or unary operators , then the cube may return different results than previous versions of analysis services 如果多维数据集包含带有自定义级别公式的维度，并且还包含前后都带有自定义成员公式和/或一元运算符的维度，那么该多维数据集可能会返回与早期版本的analysis services不同的结果。
Unary operators on non - parent - child hierarchies have limited support unary operators on hierarchies other than parent - child hierarchies are not supported in microsoft sql server 2005 analysis services unless there is an attribute relationship between the attributes sourcing the levels in the hierarchy 除非层次结构中以级别为源的属性之间存在属性关系，否则在microsoft sql server 2005 analysis services中不支持父子层次结构之外的层次结构上的一元运算符。
