| [parameters](/cells/python-net/zh/aspose.cells.externalconnections/dbconnection/parameters) |  |
| [command](/cells/python-net/zh/aspose.cells.externalconnections/dbconnection/command) |包含传递给数据提供者 API 的数据库命令的字符串将
<br/>与外部源交互以检索数据|
| [command_type](/cells/python-net/zh/aspose.cells.externalconnections/dbconnection/command_type) |指定 OLE DB 命令类型。
<br/>1.查询指定一个Cube名称
<br/>2.查询指定SQL语句
<br/>3.查询指定表名

<br/>对于 ODBC 连接，serverCommand 通常是一个比 command 更广泛的查询（无
<br/>前者存在 WHERE 子句）。基于这两个命令（Command 和 ServerCommand），
<br/>可以填充参数 UI 并构建参数化查询|
