使用自定义字段查询一数值列最大值加1，UI界面打开出错

select (case when max(FDCCY_JJJGBAZS.ZSNNXHN)   is null  then 1
          when max(FDCCY_JJJGBAZS.ZSNNXHN)  is not null  then max(FDCCY_JJJGBAZS.ZSNNXHN)+1
  end) as custom10 custom10 from FDCCY_JJJGBAZS FDCCY_JJJGBAZS where FDCCY_JJJGBAZS.JJJGBAZS_ZSDYND   =:S_ZSDYND
这是语法，测试正常

你好楼主，这个问题帮你远程看一下，您可以按照签名中的联系方式联系我（等待远程申请）

没有等到远程，我自己改用视图的办法解决了。
结帐吧
