存储过程的输入输出参数在sql串中的拼写

现有存储过程包含两个输入参数和四个输出参数

实体类&＃xff1a;

private String userId;//用户id
private String userName;//用户姓名
private String officeId;//部门id
private String officeName;//部门名称
private Integer createWkstNum;//创建工单数
private Integer handleNum;//待处理工单数
private Integer claimNum;//待认领工单数
private Integer alreadyHandleNum;//已办理工单数
private Integer overdueNum;//已超期工单数
private String workNo;//工号

mapper文件

 

  {call p_wkststate_num_by_userids(
  #{userId,mode&＃61;IN,jdbcType&＃61;VARCHAR},
  #{officeId,mode&＃61;IN,jdbcType&＃61;VARCHAR},
 
  #{overdueNum,mode&＃61;OUT,jdbcType&＃61;INTEGER},
 
  #{handleNum,mode&＃61;OUT,jdbcType&＃61;INTEGER},
  #{claimNum,mode&＃61;OUT,jdbcType&＃61;INTEGER},
  #{alreadyHandleNum,mode&＃61;OUT,jdbcType&＃61;INTEGER}
  )} 
 
]]> 

 

根据业务需求需要动态的根据时间查询员工相关工单各个状态工单的数量

所以需要增加两个输出参数

in begin_date varchar(64),in end_date varchar(64),in user_id varchar(64),in office_id varchar(64),out overdue_num int,out handle_num int,out claim_num int,
out already_handle_num int

mapper与之对应也增加两个输出参数

 

  {call p_wkststate_num_by_userids(
  #{beginDate,mode&＃61;IN,jdbcType&＃61;VARCHAR},
  #{endDate,mode&＃61;IN,jdbcType&＃61;VARCHAR},
 
  #{userId,mode&＃61;IN,jdbcType&＃61;VARCHAR},
  #{officeId,mode&＃61;IN,jdbcType&＃61;VARCHAR},
 
  #{overdueNum,mode&＃61;OUT,jdbcType&＃61;INTEGER},
 
  #{handleNum,mode&＃61;OUT,jdbcType&＃61;INTEGER},
  #{claimNum,mode&＃61;OUT,jdbcType&＃61;INTEGER},
  #{alreadyHandleNum,mode&＃61;OUT,jdbcType&＃61;INTEGER}
  )} 
 
]]> 

存储过程变为&＃xff1a;

为了方便&＃xff0c;双斜杠为注释符号

1&＃xff0c;输入参数用‘,参数,’标记

2&＃xff0c;输出参数用&＃64;参数标记

3&＃xff0c;需要注意的是在拼接sql串的情况下&＃xff0c;java代码传输入的字符串参数需要强制加单引号

否则传到sql的时候就没有单引号了&＃xff0c;会报错

如&＃xff1a; uv.setEndDate("&＃39;"&＃43;uVo.getEndDate()&＃43;"&＃39;");
uv.setUserId("&＃39;"&＃43;uv.getUserId()&＃43;"&＃39;");
uv.setOfficeId("&＃39;"&＃43;uv.getOfficeId()&＃43;"&＃39;");

否则sql解析时则不是字符串

4&＃xff0c;mapper中没有日期类型的参数

用TO_DAYS(日期&＃xff09;解析字符串日期

注意&＃xff1a;

最近又对这个存储过程编写的时候发现一个bug:

sql串的拼写时时间的比较 一定要用  <&＃61;  而不是  <   否则查询结果有误&＃xff0c;真是奇了怪

环境&＃xff1a;windows下的5.6.21
