+------+-------+------+-------+
|    1 |     0 |    1 |     0 |
+------+-------+------+-------+

create table xs
(
   id int primary key,
   bl boolean
)

private Boolean comment ;

<if test="comment !=null and comment !=''">  
    comment=#{comment},  
</if>  

<if test="comment !=null">  
    comment=#{comment},  
</if>  

<label class="col-sm-1 control-label padA01">是否是物联网表</label>
<div class="col-sm-3">
    <select id="isNbMeter" class="fORM-control">
        <option value=true selected>是</option>
        <option value=false>否</option>
    </select>
</div>

$("#installDate").val("");
$("#inUseMeter").val=true;
$("#inUseMeter").find("option[value=true]").attr("selected",true);
$("#isNbMeter").val=true;
$("#imei").val("");
$("#meterState").val(1);

$("#inUseMeter").val=false;
$("#inUseMeter").find("option[value=false]").attr("selected",true);

<if test="flag != null">
   flag = #{flag,jdbcType=TINYINT},
</if>
