<select id="getStoreInfo" parameterType="java.util.Map" resultType="com.goldenvista.kjt.entity.message.StoreInfo">
SELECT 
s.store_id as store_id,

WHERE 
s.store_id = o.store_id

</select>

TO_CHAR 是把日期或数字转换为字符串 
TO_CHAR(number, ‘格式‘)
TO_CHAR(date,’格式’)

例如：
TO_CHAR(salary,’$99,999.99’) 
TO_CHAR(newdate,’yyyy-mm-dd’) 

指定字符串的长度可以使用lpad或者rpad或者substring：

lpad(字段名,填充长度,填充的字符) 左填充
rpad(字段名,填充长度,填充的字符) 右填充
substr( string, start_position, [ length ] )取得字符串中指定起始位置和长度的字符串
