使用powershell运行带有detediff和逗号的access查询

$connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\path\to\your\database.accdb"
$connection = New-Object System.Data.OleDb.OleDbConnection($connectionString)
$connection.Open()

$queryString = "SELECT detediff, column1, column2 FROM tableName"
$command = New-Object System.Data.OleDb.OleDbCommand($queryString, $connection)
$dataAdapter = New-Object System.Data.OleDb.OleDbDataAdapter($command)
$dataTable = New-Object System.Data.DataTable
$dataAdapter.Fill($dataTable)

$dataTable | Export-Csv -Path "C:\path\to\output.csv" -NoTypeInformation
