从 powershell 连接 SAP HANA 数据库

Question

我正在使用以下 Power Shell 代码从安装了 HANA 客户端的主机连接到 HANA 实例 -

    function Get-OLEDBData ($connectstring, $sql) {
    $OLEDBConn = New-Object System.Data.OleDb.OleDbConnection($connectstring)
    $OLEDBConn.open()
    $readcmd = New-Object system.Data.OleDb.OleDbCommand($sql,$OLEDBConn)
    $readcmd.CommandTimeout = '300'
    $da = New-Object system.Data.OleDb.OleDbDataAdapter($readcmd)
    $dt = New-Object system.Data.datatable
    [void]$da.fill($dt)
    $OLEDBConn.close()
    return $dt
    }

    $hdbSqlCmd = "myquery"
    $hdbConnectionString = "Driver={HDBODBC};ServerNode=myserver:30015;UID=myuser;PWD=mypasswd;"
    Get-OLEDBData $hdbConnectionString $hdbSqlCmd**

但我得到以下错误 -

   New-Object : Exception calling ".ctor" with "1" argument(s): "An OLE DB Provider was not specified in the ConnectionString.  An example would be, 'Provider=SQLOLEDB;'."
   At C:\myspace\hana_connect_1.ps1:5 char:27+    $OLEDBConn = New-Object <<<<  System.Data.OleDb.OleDbConnection($connectstring)
+ CategoryInfo          : InvalidOperation: (:) [New-Object],        MethodInvocationException
+ FullyQualifiedErrorId : ConstructorInvokedThrowException,Microsoft.PowerShell.Commands.NewObjectCommand

当我将连接字符串更改为 Provider 而不是 Driver -

   $hdbConnectionString = "Provider={HDBODBC};ServerNode=myserver:30015;UID=myuser;PWD=mypasswd;"

我遇到以下错误 -

   Exception calling "Open" with "0" argument(s): "The '{HDBODBC}' provider is not registered on the local machine."
   At C:\myspace\hana_connect_1.ps1:6 char:19
   +    $OLEDBConn.open <<<< ()
  + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException

换成32位驱动-HDBODBC32，报错还是一样，提示HDBODBC32未注册

我现在迷路了，谁能帮帮我！！

SAP HANA ODBC 驱动程序不是OLEDB 驱动程序。因此，您必须改用 ODBC API：

 function Get-ODBCBData ($connectstring, $sql) {
    $Conn = New-Object System.Data.odbc.ODBCconnection($connectstring)
    $Conn.open()
    $readcmd = New-Object system.Data.odbc.ODBCCommand($sql,$Conn)
    $readcmd.CommandTimeout = '300'
    ...
    $hdbConnectionString = "Driver={HDBODBC};ServerNode=myserver:30015;UID=myuser;PWD=mypasswd;"
    Get-ODBCBData $hdbConnectionString $hdbSqlCmd**

应该可以。
