mysql - mysql select 查询的循环

Question

For Each row In Item_Get(42, returnno)
    Dim barcode As String = Item_Get(42, returnno)
    Dim wh, sa, bo As Integer
    wh = Stat_Get(0, barcode)
    sa = Stat_Get(1, barcode)
    bo = Stat_Get(2, barcode)
    chk = Stock_Chk(0, barcode)
    If chk = True Then
        Stock_Update(barcode, wh, sa, bo)
    Else
        Stock_Save(barcode, wh, sa, bo)
    End If
Next

item_get(42, returno) 查询是“从 tblreturn 选择条形码作为 str，其中 status = '1' 且 returnno = @chk”

问题是它没有循环整个返回的结果。有人能帮我一下吗 ？

Answer 1

在 For 循环中，您不应从 Item_Get(42, returnno) 获取数据 而是来自 row。这意味着类似 Dim Barcode As String = row.item(0)
