MSSQL生成连续的时间。(也可以生成连续的数字等) master..spt_values SELECT DATEADD(DAY, -t1.number, GETDATE()) FROM master..spt_values t1 WHERE t1.[type] = 'p' AND t1.number < 7
MSSQL语句 一、获取两个日期之间的所有日期 是的话可以这样来实现 declare @sdate datetime,@edate datetime set @sdate = '2009/10/1' set @edate = '2009/10/10' select DATEADD(day,number,@sdate) from master..spt_values where type = 'P' and DATEADD(day,number,@sdate) <= @edate; 二、...

函数名:SQLCallback(nFuncType, cFuncName[,nFreq]) 缩写:sqlc SQL回调函数。采用一种插入技术,在VFP使用ODBC连接远程数据源过程中,能够调用vfp的程序。 同时支持SPT和CA,支持SQLIdleDisconnect。 目前支持两个回调函数,Fetch和RecordCount,可以用来在SPT下载数据过程产生一个进度信息。使用简便,性能要远高于异步方式...
