【新手请教】

sqlCmd = "SELECT RANK() OVER (ORDER BY 下次随访日期 ) AS '序号',pm.住院号,fluplist.* FROM (SELECT  DID AS '患者编号',sickName AS '患者姓名',DATEADD(""Month"", flupCycle,flupDate) AS '下次随访日期',   flupDate AS '上次随访日期',flupState AS '随访状态',flupCycle AS '随访周期', flupNote AS '随访备注', updateDate AS '更新日期',id as '编号' from flup  WHERE  "

监视这段字符串时为什么没有拼到最后？如下图：

字符串变量长度没有限制

有时候可以有时候不可以。。。郁闷中……请教各位，拜谢！
