Question

我运行了一个MySQL查询，它给了我一个可以使用的结果集。

但是，我现在需要将其导出为CSV文件。

如果我跑

$result1 | export-csv "c:\path\to\csv.csv"

我只在第一个单元格中获得一个包含单个条目的文件：

#TYPE System.Int32

但是应该有apx 6000行。

如果我这样做

$result1 | Get-member

我明白了：

TypeName: System.Int32

Start             Property              System.DateTime Starttime {get;set;}

将此转换为CSV文件的正确方法是什么？

write-host $result1为我提供了类似下面的数据：

CJ            : 
JN            : 
Name          : Mr Smith
Start         : 
End           : 

CJ            : 987654321
JN            : 
Name          : Mr Jones
Starttime     : 29/09/2015 08:00:00
Endtime       : 29/09/2015 08:30:00

通过创建PSObject，然后将其转换为CSV，我找到了一种方法来完成这项工作。

$a = 0
$data = @()
foreach($res in $result1)
    {
        if($a -eq 0)
            {
                #Do Nothing
            }
        else
            {
                $cj = $res.CJ
                $jn = $res.JN
                $en = $res.Name
                $st = $res.Start
                $et = $res.End

                #write-host "$cj,$jn,$en,$st,$et"

                $row = New-Object PSObject
                $row | Add-Member -MemberType NoteProperty -Name "CJ" -Value $cj -force
                $row | Add-Member -MemberType NoteProperty -Name "JN" -Value $jn -force
                $row | Add-Member -MemberType NoteProperty -Name "Name" -Value $en -force
                $row | Add-Member -MemberType NoteProperty -Name "Start" -Value $st -force
                $row | Add-Member -MemberType NoteProperty -Name "End" -Value $et -force

                $data += $row         
            }
         $a++   
    }

$data | Export-Csv "c:\path\to\csv.csv" -NoTypeInformation

将dataRow导出到csv
