The BETWEEN function can also be combined with the NOT operator. Now we want to exclude the records with a hiredate between “01-JAN-1980”and 31-DEC-1980. To illustrate the usage of the SQL NOT BETWEEN command we are going to use the EMP table. SELECT * FROM emp WHERE hiredate NOT...
这些子句可以两种方式使用:以AND子句的方式或OR子句的方式使用。操作符(operator) 用来联结或改变WHERE子句中的子句的关键字。也称为逻辑操作符(logical operator)。 AND操作符OR操作符计算次序 问题的解决方法是使用圆括号明确地分组相应的操作符。 2、IN操作符...

After the column name comes theBETWEENoperator and two more value expressions separated byAND. The search condition will resolve to “true” for any rows whose value from the specified column is greater than or equal to the first of the two values separated byAND, but less than or equal to...

BETWEEN SYMMETRIC和BETWEEN相似,不过BETWEEN SYMMETRIC不要求AND左边的参数小于或等于右边的参数。如果左参数不是小于等于右参数,这两个参数会自动被交换,这样总是会应用一个非空范围。 当有一个输入为空时,普通的比较操作符会得到空(表示"未知"),而不是真或假。例如,7 = NULL得到空,7 <> NULL也一样。如果这...
The behavior parameter lets you specify options that control the behavior of the command and its connection.
