我正在做一个Powershell，它通过循环从具有不同参数的sql查询中获取结果。问题只是循环的第一轮运行才有结果。其余所有空白结果也应该显示一些结果。

$Days = @(90,60,30,15)
$Start = 0
$End = 0
$Affiliation = 1
for ($i = 0 ; $i -lt $Affiliation.Count ; $i++) { 
for ($i = 0; $i -lt $Days.Count ; $i++){
    if ($Days[$i] -eq 1) {
        $End = $Days[$i]
        $Start = 0
        write-host "Start/End r:" $Start $End
    } 
    elseIf ($index -eq $Days.Length) {
        $End = $Days[$i]
        $Start = 0
        write-host "Start/End m:" $Start $End 
    }
    else {
        $End = $Days[$i]
        $Start = $Days[$i+1] + 1
        write-host "Start/End s:" $Start $End
    }
