mybatis 语句积累

1mybatis 拼sql：

<insert id="add_tjbsld" parameterClass="tJbsld">
insert into
T_WS_JBSLD(

<isNotEmpty prepend="" property="id">
id
</isNotEmpty>
<isNotEmpty prepend="," property="wh">
wh
</isNotEmpty>

)values(
<isNotEmpty prepend="" property="id">
#id#
</isNotEmpty>
<isNotEmpty prepend="," property="wh">
#wh#
</isNotEmpty>

)

如果为空 ，就不拼写在sql中。
