Arithmetic operators perform mathematical operations on two expressions of one or more of the data types of the numeric data type category. For more information about data type categories, see Numeric Types and Literals. 展开表 OperatorMeaning + (Add) Addition - (Subtract) Subtraction * (Multiply...
Operators fall into six groups: arithmetic, comparison, character, logical, set, and miscellaneous. SQL utilizes three types of operators: arithmetic, comparison, and logical. Arithmetic OperatorsThe arithmetic operators are plus (+), minus (−), divide (/), multiply (*), and modulo (%). T...
Arithmetic ExpressionArithmetic Expression运算符根据行中的现有值计算新值。 在较新版本的 SQL Server 中不使用算术表达式。 AssertAssert运算符用于验证条件。 例如,验证引用完整性或确保标量子查询返回一行。 对于每个输入行,Assert运算符都要计算执行计划的“属性”窗格中的表达式。 如果此表达式的值为NULL,则通过...
When there is more than one arithmetic operator in an expression, multiplication and division are calculated first, followed by subtraction and addition. When all the arithmetic operators in an expression have the same level of precedence, the order of execution is left to right. ...
Anarithmetic expression can be creaeted using thecolumn names, operators andconstant values to embed an expression in a SELECT statement. 算术表达式可以使用列名称、运算符和常量值嵌入一个SELECT语句中的表达创建。 The operator applicable to acolumn depends on column'sdata type. ...
