从 IronPython 访问 MS Access 时出现问题

Question

我正在尝试运行在 MS Access 中使用 Spotfire 中的 IronPython 编写脚本。到目前为止，我什至无法连接到 MS Access。

这是我的连接代码：

import clr
import System
clr.AddReference("System.Data")

from System.Data import DataSet
from System.Data.Odbc import OdbcConnection, OdbcDataAdapter

connectString = (
    "Driver={Microsoft Access Driver (*.mdb, *.accdb)};"
    "Dbq=\\olgwfap1\Data\Development Division\Res Surv Eng\Personal Folders\Pruet\Data Team\SPOTFIRE\TIDELANDS\Tidelands_Spotifre.accdb;"
    "Uid=Admin;PWd=;"
)

query = "Select * From FOP_Calc"


connection = OdbcConnection(connectString)
adaptor = OdbcDataAdapter(query, connection)
dataSet = DataSet()
connection.Open()
adaptor.Fill(dataSet)
connection.Close()

执行此操作时，出现以下错误：

System.Data.Odbc.OdbcException (0x80131937): ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified at System.Data.Odbc.OdbcConnection.HandleError(OdbcHandle hrHandle, RetCode retcode) at System.Data.Odbc.OdbcConnectionHandle..ctor(OdbcConnection connection, OdbcConnectionString constr, OdbcEnvironmentHandle environmentHandle) at System.Data.Odbc.OdbcConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionFactory.TryGetConnection(DbConnection owningConnection, TaskCompletionSource1 retry, DbConnectionOptions userOptions, DbConnectionInternal& connection) at System.Data.ProviderBase.DbConnectionClosed.TryOpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource1 retry, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionInternal.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.Odbc.OdbcConnection.Open() at stub6##296(Closure , CallSite , CodeContext , Object ) at Microsoft.Scripting.Actions.MatchCaller.Call2[T0,T1,TRet](Func4 target, CallSite site, Object[] args) at Microsoft.Scripting.Actions.CallSite1.UpdateAndExecute(Object[] args) at Microsoft.Scripting.Actions.UpdateDelegates.Update2[T,T0,T1,TRet](CallSite site, T0 arg0, T1 arg1) at 7##287(Closure , Scope , LanguageContext ) at Spotfire.Dxp.Application.ScriptSupport.IronPythonScriptEngine.ExecuteForDebugging(String scriptCode, Dictionary2 scope, Stream outputStream) at Spotfire.Dxp.Application.Scripting.ScriptService.ExecuteForDebugging(String scriptCode, Dictionary2 scope, Stream outputStream) at Spotfire.Dxp.Application.Scripting.ScriptManager.<>c__DisplayClass14.b__f() at Spotfire.Dxp.Framework.Commands.CommandHistory.Transaction(Executor executor, Boolean visible, Boolean sticky, Guid stickyGuid) at Spotfire.Dxp.Framework.Commands.CommandHistory.Transaction(String displayName, Executor executor) at Spotfire.Dxp.Framework.DocumentModel.DocumentNode.Transaction(String displayName, Executor executor) at Spotfire.Dxp.Application.Scripting.ScriptManager.ExecuteScriptForDebugging(String scriptCode, Dictionary`2 scriptArguments, String& output) at Spotfire.Dxp.Forms.Framework.Scripting.ScriptEditDialog.RunButton_Click(Object sender, EventArgs e)

文件名绝对正确所以我假设它是给它带来麻烦的默认驱动程序。

如果有任何区别，我的 SpotFire（承载 IronPython）是 64 位安装，我使用的是 MSOffice 32 位（不过我确实安装了 64 位和 32 位 MS Access ODBC 驱动程序）。

感谢任何帮助，谢谢。

Answer 1

如果您的 IronPython 脚本是运行在 64 位环境中，那么您需要安装 64 位版本的 Access 数据库引擎。或者相反，如果您安装了 32 位版本的 Access 数据库引擎（因为您有 32 位 Office），那么您的 IronPython 脚本需要在 32 位环境中运行。

可以强制 Access 数据库引擎的 32 位和 64 位版本驻留在同一台计算机上，但不建议这样做。它可能会导致 Office 出现问题，并且不是受支持的配置。
