1·In writing an assignment statement, for example, you can declare variables of any type, use any identifier to the left of the equal sign, and supply any expression on the right.
例如你要写一句赋值语句,你可以声明任何类型的变量,在等号的左边使用任何标识符,然后在右边给出任何的表达式。
2·So this is the equality operator, whereas the single equal sign is the assignment operator.
所以这是相等操作符,然而那个单等号是一个赋值运算符。
3·What does an equal sign do?
一个等号是用来做什么的?
4·In the first statement, PRIOR is used to the left of the equal sign while in the second statement it is specified on the other side.
在第一个语句中,PRIOR用于等号的左边,而在第二个语句中,它被指定在另一边。
5·If we examine each attribute, especially the data portion (the part to the right of the equal sign), we can determine whether they actually represent data, or metadata.
如果我们检查每个属性,特别是数据部分(等号右边的部分),就可以确定它们是否真的表示数据或元数据。
