mysql 不等于 一些 写法

http://stackoverflow.com/questions/32042726/what-is-the-proper-syntax-for-the-less-than-equal-operator-in-mybatis-3

I show examples for the Greater Than/Equal Operator and the Less Than/Equal Operators:

ROWNUM >= 20
ROWNUM <= 20

Or, for readability, you can wrap them in CDATA

ROWNUM <![CDATA[ >= ]]> 20
ROWNUM <![CDATA[ <= ]]> 20
