EntityFramework在不同數據庫下的配置

EntityFramework默認只支持SQLServer數據庫，如果想要支持其他數據庫，要安裝相應的插件。

如支持Oracle，要安裝Oracle Data Access Components (ODAC)，支持MySQL要安裝mysql-connector-net-6.4.6等

下面列舉下3種數據庫下的配置：

1.SQLServer：

<connectionStrings>
    <add name="EntityDesignEntities" connectionString="metadata=res://*/EntityDataModel.EntityDesign.csdl|res://*/EntityDataModel.EntityDesign.ssdl|res://*/EntityDataModel.EntityDesign.msl;provider=System.Data.SqlClient;provider connection string="data source=.;initial catalog=DevBase;persist security info=True;user id=sa;password=xxx;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
  </connectionStrings>

 

2.Oracle：

<connectionStrings>
    <add name="EntityDesignEntities" connectionString="metadata=res://*/EntityDataModel.EntityDesign.csdl|res://*/EntityDataModel.EntityDesign.ssdl|res://*/EntityDataModel.EntityDesign.msl;provider=Oracle.DataAccess.Client;provider connection string="data source=xe;password=xxx;persist security info=True;user id=sa"" providerName="System.Data.EntityClient"/>
  </connectionStrings>

 

3.MySQL:

<connectionStrings>
    <add name="EntityDesignEntities" connectionString="metadata=res://*/EntityDataModel.EntityDesign.csdl|res://*/EntityDataModel.EntityDesign.ssdl|res://*/EntityDataModel.EntityDesign.msl;provider=MySql.Data.MySqlClient;provider connection string="server=localhost;user id=sa;password=xxxx;persist security info=True;database=world"" providerName="System.Data.EntityClient"/>
  </connectionStrings>
