-- 不load数据,自动编号重复问题
订单表不load数据,tables("订单“).addnew之后,每次打开ft之后,都是自动编号重复同一个号码,怎么判断后台数据已经有相同编号的订单,并且判断哪个订单号是最新的,在最新的订单号后面开始增加编号?
Select e.DataCol.Name
Case
"制单日期","工程代码"
If e.DataRow.IsNull("制单日期")
OrElse e.DataRow.IsNull("工程代码")
Then e.DataRow("单据编号") = Nothing
Else
Dim d As
Date = e.DataRow("制单日期")
Dim y As
Integer =
d.Year
Dim
m As
Integer = d.Month
Dim Days As
Integer =
Date.DaysInMonth(y,m)
Dim fd As
Date = New Date(y,m,1) \'获得该月的第一天
Dim ld As
Date = New Date(y,m,Days)
\'获得该月的最后一天
Dim bh As
String = e.DataRow("工程代码") & "-" & Format(d,"yyyyMM") &
"-"
\'生成编号的前缀
If e.DataRow("单据编号").StartsWith(bh) = False
\'如果单据编号前缀不符
Dim max As
String
Dim idx As
Integer
Dim flt As
String flt = "工程代码 = \'"& e.DataRow("工程代码")
& "\' And 制单日期 >=
#" & fd & "# And 制单日期 <=
#" & ld & "# And [_Identify]
<> " & e.DataRow("_Identify") max = e.DataTable.Compute("Max(单据编号)",flt) \'取得该月的相同工程代码的最大单据编号
If
max > ""
Then
\'如果存在最大单据编号 idx = CInt(max.Substring(12,4)) + 1
\'获得最大单据编号的后四位顺序号,并加1
Else idx = 1
\'否则顺序号等于1
End
If e.DataRow("单据编号") = bh
& Format(idx,"0000")
End
If
End
If End
