Question

我正在寻找使用Microsoft.ACE.OLEDB.12.0命令对象执行MS Access命名查询的语法。

我看到很多使用表的例子，但是还没有用于查询。替换查询名称的表名似乎不起作用。即从'myquery'中选择*

这是我的代码段：

$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.Open();

$OleDbCmd.Connection = $OleDbConn;
$OleDbCmd.CommandText = "'myQuery'"; # name query in MS Access db
$OleDbCmd.CommandType = [System.Data.CommandType]::StoredProcedure;
$OleDbAdapter.SelectCommand = $OleDbCmd;

$RowsReturned = $OleDbAdapter.Fill($DataTable);
Write-Host $RowsReturned;

错误：使用“1”参数调用“Fill”的异常：“Microsoft Access数据库引擎找不到输入表或查询''实验手册''。确保它存在并且其名称拼写正确。“

诀窍是在查询名称前添加命令'Execute'，并在查询名称周围使用方括号。

$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=c:\temp\labmanual.mdb;";
$OleDbCmd.Connection = $OleDbConn;
$OleDbCmd.CommandText = "Execute [myQuery]";

$OleDbAdapter.SelectCommand = $OleDbCmd;

$OleDbConn.Open();
$RowsReturned = $OleDbAdapter.Fill($DataTable);


Write-Host $RowsReturned;

$OleDbConn.Close();
