vbscript数组循环，打印问题

Question

I have a recordset like this:

row1 = Type1, partid, partname

row2 = Type2, partid, partname

row3 = Type2, partid, partname

I want my output to be like this:

Type1: partid partname

Type2: partid partname, partid, partname

or

Type2: partid partname, partid, partname

Type1: partid partname

(depending on how the sort works out)

I have my results sorted by the Type value. I may or may not get same Types in a result, but if so the result is required to be printed as above.

I'm using .getRows() to get the recordset into an array.

I can't for the life of me figure out how to decide in the loop whether to print a break tag or a comma.

You need to check for a change in the type column. In that case, print <br /> and the type. In code:

Set r = CreateObject("ADODB.Recordset")
r.Fields.Append "t", 3
r.Fields.Append "i", 3
r.Fields.Append "n", 3
r.Open
r.AddNew : r.Fields("t") = 1 : r.Fields("i") = 10 : r.Fields("n") = 10
r.AddNew : r.Fields("t") = 2 : r.Fields("i") = 20 : r.Fields("n") = 21
r.AddNew : r.Fields("t") = 2 : r.Fields("i") = 22 : r.Fields("n") = 22
r.AddNew : r.Fields("t") = 3 : r.Fields("i") = 30 : r.Fields("n") = 31
r.MoveFirst
a = r.GetRows()
t = a(0, 0)
WScript.StdOut.Write a(0, 0)
For r = 0 To UBound(a, 2)
    If t <> a(0, r) Then
       WScript.StdOut.Write "<br />" & a(0, r)
       t = a(0, r)
    End If
    WScript.StdOut.Write Join(Array("", a(1, r), a(2,r)), ",")
Next

output:

cscript 24441584.vbs
1,10,10<br />2,20,21,22,22<br />3,30,31
