  1. POWindows ODBC Datasources and .Net System.Data.Odbc: Which driver is used?
    text
    copied!<p>I am confused on how to connect to Oracle via ODBC.</p> <p>I have created an ODBC datasource named "<strong>oracle</strong>" in my Control Panel > Administrative Tools, and used the driver "Microsoft ODBC for Oracle".</p> <p>In my app.config , I have the following connection strings</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;configuration&gt; &lt;configSections&gt; &lt;/configSections&gt; &lt;connectionStrings&gt; &lt;add name="MappingAssistantGui2.Properties.Settings.maConnectionString" connectionString="Dsn=oracle;uid=ma;pwd=ma" providerName="System.Data.Odbc" /&gt; &lt;add name="MappingAssistantGui2.Properties.Settings.maConnectionStringSqlServer" connectionString="Dsn=sqlserver;uid=sli;pwd=slislisli" providerName="System.Data.Odbc" /&gt; &lt;add name="MappingAssistantGui2.Properties.Settings.maConnectionStringOracle" connectionString="Dsn=oracle;uid=ma;pwd=ma" providerName="System.Data.Odbc" /&gt; &lt;/connectionStrings&gt; &lt;startup&gt; &lt;supportedRuntime version="v2.0.50727" /&gt; &lt;/startup&gt; &lt;/configuration&gt; </code></pre> <p>In my code I use the connection string maConnectionString (the first one). I am confuse on what driver is being used underneath:</p> <ol> <li>Microsoft ODBC for Oracle</li> <li>System.Data.Odbc</li> <li>Are these two the same? </li> <li>Or are the System.Data.Odbc classes through which I am accessing the driver? I mean, is "Microsoft ODBC for Oracle" an implementation of ODBC access for Oracle, created by Microsoft? </li> <li>Something else?</li> </ol> <p>Do I <strong>need</strong> to have defined an ODBC datasource to be connecting with System.Data.Odbc namespace to a database (whichever of Oracle, SQL Server, MySQL)?</p> <p>Thanks!</p>
