从函数调用Powershell
脚本时C
,我的数据库连接没有打开。但是,当我以运行C
程序的用户身份登录服务器并从 DOS 提示符启动它时,一切都按预期工作。
为什么C
程序无法通过C
.
服务器是 Windows 2008 R2 64 位。
这是Powershell
我正在运行的脚本。它为我创建了一个调试日志来验证哪些部分正在工作。
$DEBUGStream = [System.IO.StreamWriter] "D:\powershell\DEBUG.txt"
$DEBUGStream.WriteLine("START DEBUG")
$ExcelFile = "D:\InterfaceData\excel\" + $args[0]
$Sheetname = "Sheet2$"
$OleDbConn = New-Object “System.Data.OleDb.OleDbConnection”
$OleDbCmd = New-Object “System.Data.OleDb.OleDbCommand”
$OleDbAdapter = New-Object “System.Data.OleDb.OleDbDataAdapter”
$DataTable = New-Object “System.Data.DataTable”
$OleDbConn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=`"$ExcelFile`";Extended Properties=`"Excel 12.0 Xml;HDR=YES`";"
$OleDbConn.Open()
$DEBUGStream.WriteLine("Connection: $OleDbConn.State")
$DEBUGStream.WriteLine("Environment: $env:Processor_Architecture")
$OleDbCmd.Connection = $OleDbConn
$OleDbCmd.commandtext = “Select * from [$Sheetname]”
$OleDbAdapter.SelectCommand = $OleDbCmd
$RowsReturned = $OleDbAdapter.Fill($DataTable)
$DEBUGStream.WriteLine("Data Table fill: Rows: $RowsReturned")
$intRow = 1
ForEach ($DataRec in $DataTable) {
$DEBUGStream.WriteLine("DATA TABLE ROW $intRow")
$intRow++
}
$DEBUGStream.WriteLine("Loop finished")
$OleDbConn.Close()
$DEBUGStream.WriteLine("All Closed")
$DEBUGStream.close()
这是我从 DOS 提示符手动运行时的输出
C:\Users\me>powershell -executionpolicy bypass d:\powershell\Interface.ps1 test.xlsx
START DEBUG
Connection: Open
Environment: AMD64
Data Table fill: Rows: 4
DATA TABLE ROW 1
DATA TABLE ROW 2
DATA TABLE ROW 3
DATA TABLE ROW 4
Loop finished
All Closed
C
这是从程序调用时的输出。我使用system
命令调用它。
START DEBUG
Connection: Closed
Environment: x86
Data Table fill: Rows:
Loop finished
All Closed
编辑
如果我运行 64 位Powershell
版本并从命令提示符运行脚本,我会收到一个新错误。我已经安装了 64 位版本的 Microsoft Access Database Engine 2010 (14.0.4763.1000):
