1、在navicat中显示的样子，中文都正常

2、在设计器里，中文全部变成乱码

3、是因为什么原因？帆软之前做别的报表中文都正常显示？是我写的语句的问题吗？4、我写的语句是：

SELECT zswsxz,zswid,

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.SWID'),"\"","") else null end as 'SWID',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.XH'),"\"","") else null end as 'XH',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.JDDZ'),"\"","") else null end as 'JDDZ',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.PBZRL'),"\"","") else null end as 'PBZRL',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.SCCJMC'),"\"","") else null end as 'SCCJMC',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.SCCJ'),"\"","") else null end as 'SCCJ',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.CCBH'),"\"","") else null end as 'CCBH',

case when JSON_VALID(zswsxz) then replace(JSON_EXTRACT(zswsxz,'$.CCRQ'),"\"","") else null end as 'CCRQ'

FROM ( 

select replace(zswsxz,"'","\"") zswsxz,zswid

from dws_grid_wzjscs

where eartx ='箱式变电站'

and name1 like '%城西%'
