Powershell 对 Excel 工作簿进行多个 SQL 查询

首先，如果这是一个重复的问题，我深表歉意。我搜索了又搜索，但没有找到任何可以解决我所遇到的问题的内容。

我的目标是使用 7 个 Powershell 脚本，将 SQL 查询中的 CSV 输出到 1 个 Excel 工作簿中，每个 CSV 位于不同的工作表中。

我找到了这个https://social.technet.microsoft.com/Forums/scriptcenter/en-US/ef70e191-1b2e-4ba8-8845-58c4b1159ab7/multiple-csvs-into-multiple-sheets-of-an-excel https://social.technet.microsoft.com/Forums/scriptcenter/en-US/ef70e191-1b2e-4ba8-8845-58c4b1159ab7/multiple-csvs-into-multiple-sheets-of-an-excel哪个有效但是 Excel 工作簿结果将第一列作为最后一列。

function Export-Excel{
[cmdletBinding()]
Param([Parameter(ValueFromPipeline=$true)]
[string]$junk)

begin{
    $header=$null
    $row=1
}
process{
    if(!$header){
        $i=0
        $header=$_ | Get-Member -MemberType NoteProperty | select name
        $header | %{$Global:ws.cells.item(1,++$i)=$_.Name}
    }
    $i=0
    ++$row
    foreach($field in $header){
        $Global:ws.cells.item($row,++$i)=$($_."$($field.Name)")
    }
}

}

$xl=New-Object -ComObject Excel.Application
$wb=$xl.WorkBooks.add(1)
$Global:ws=$wb.WorkSheets.item(1)
$Global:ws.Name='Sunday'
import-csv 'C:\Sunday.csv' | Export-Excel

最终完成了以下工作。如果有更有效的方法，请告诉我。 SQL结果发送到Excel以利用EntireColumn.AutoFit()并将每个 SQL 查询结果放在其自己的工作表上。
