窗口4个按钮:
1.客户 = 'CS02'
Select Top 2 * from{订单} where 客户 = 'CS02' order by 日期 desc
2.雇员 = 'EP03'
select Top 1 * from{订单} where 雇员 = 'EP03' order by 日期 desc
3.客户 = 'CS02' Union 雇员 = 'EP03'
Select top 2 * from{订单} where 客户 = 'CS02' order by 日期 desc union select top 1 * from{订单} where 雇员 = 'EP03' order by 日期 desc
4. 雇员 = 'EP03 Union '客户 = 'CS02'
select top 1 * from{订单} where 雇员 = 'EP03' order by 日期 desc union select top 2 * from{订单} where 客户 = 'CS02' order by 日期 desc
需求:是 1 按钮 和 2 按钮结果的组合
PD01 CS02 EP01 300 1999/6/30
PD02 CS02 EP02 400 1999/6/29
PD01 CS05 EP03 60 1999/6/30
结果 :
3 按钮的结果:雇员 = 'EP03',不是最近日期;
4 按钮的结果:客户 = 'CS02',不是最近日期
3 按钮 和 4 按钮 的结果 也有出入
