navicat导出longtext类型数据乱码的解决方案

1. 一、先使用sql查询出需要导出的内容，将longtext类型使用cast转化成char类型

2. SELECT

   company_id,
     wechat_mp_appid,
     CAST(survey_risk_tips_org AS char)AS survey_risk_tips_org,
     CAST(survey_disclaimer AS char) AS survey_disclaimer,
   CAST( network_service_agreement AS char)AS network_service_agreement,
   CAST(qualified_investor_agreement AS char)AS qualified_investor_agreement,
   show_material_statement,
   time_material_statement,
   CAST(material_statement AS char)AS material_statement,
   CAST(survey_risk_tips_person AS char)AS survey_risk_tips_person,
   CAST(risk_confirmation AS char)AS risk_confirmation,
     CAST(login_tips AS char)login_tips 
   FROM
   wechat_setting w
   WHERE
   

     company_id = 0

   二运行sql语句，点击导出

   

   三、选择需要导出成的类型，然后一直点击下一步，直到完成
