PB+MSSQL+触发器必须注意
PB+MS SQL+触发器必须注意： 若触发器存在两笔以上的返回值，比如两条update 语句，被误判为数据有改变，存盘不成功。 提示： Row changed between retrieve and update. No changes made to database. 所以MS SQL 触发器必须统一处理为： 触发器开始加： if
PB+MS SQL+触发器必须注意：
若触发器存在两笔以上的返回值，比如两条update 语句，被误判为数据有改变，存盘不成功。
提示：
Row changed between retrieve and update.

触发器开始加：
if@@ROWCOUNT=0 Return --提高效能
setnocount on --不返回统计笔数，可减少网络频繁响应，提高效性能；避免误判为数据有改变（sybase不存在此类问题）
