【问题解决】Parameter index out of range (2 大于 number of parameters, which is 1)

(1)错误描述:这个错误大概是说需要的参数是一个,而你传入了两个参数,导致了参数变多抛异常

日志打印sql:

Preparing: SELECT DISTINCT app_key,channel_name FROM sms_channel 
WHERE ((entity_code = concat('B','?')) OR (entity_code = concat('P','?')))AND app_key=?

日志打印入参:

 查询ISV名称入参:venderId=6****2,appId=3FA3B5D**************D6C6215C6EE4

 

(2)错误解决

出现这种问题的最本质原因在入参跟需要传入的参数个数不一致,导致出现类似错误,多了少了的。

这时候我们应该先定位到相应位置,我这边入参传入的是String类型的,然后我在mybaits取入参的时候又加了一层引号导致它未检测到,传入两个参数而只有一个坑位,所以报错了。

原错误sql:

 @Select(
    "")

改正后sql:

 @Select(
 "")
