What is the proper syntax for the Less Than/Equal operator in MyBatis 3? -

how use less equal in mybatis 3.

<select id="getlog" resultmap="baseresultmap" parametertype="java.lang.string">     select * from(         select * table1         col1 =#{col1,jdbctype=varchar}         order date desc     ) table2     rownum <= 20 </select> 

i show examples greater than/equal operator , less than/equal operators:

rownum >= 20 rownum <= 20 

or, readability, can wrap them in cdata

rownum <![cdata[ >= ]]> 20 rownum <![cdata[ <= ]]> 20
