Microsoft ODBC Driver for Oracle Download Free
Microsoft ODBC Driver for Oracle:
TOOLBOT MEMBERS ONLY:
Microsoft ODBC Driver for Oracle provides ActiveX Data Objects (ADO) developers with high-performance, efficient access to Oracle databases. It also offers database-specific features and data access optimizations that are not available with other third-party ODBC drivers.
Installation of Microsoft ODBC Driver for Oracle:
Oracle is a leader in the world of cloud infrastructure, and it provides numerous handy tools for users to use with their databases. One of these is the Oracle ODBC driver, which allows you to connect through an interface and access your database data from any compatible application.
To install the ODBC driver, you need to download three separate files from Oracle’s website and place them in the correct folder location. This is important, as using the wrong files can cause your ODBC driver to not function properly.
Next, you need to edit your system environment variables. To do this, press both the Windows and S keys to open the search bar. Then, enter the phrase “edit system environment variables” into the search field and select Edit the system environment variable. Input your Oracle directory into the variable path box (for example, C:Oracleinstantclient_12_2). Click OK and close the window. This step is required to ensure that your ODBC driver can find the correct directory for your Oracle database.
ODBC is an open database connectivity interface that allows programs and applications to connect to a database. The Oracle ODBC Driver makes it easier to access Oracle data from applications such as Microsoft Power BI, Excel, and ArcGIS.
The Oracle Provider for OLE DB is designed to give ActiveX Data Objects (ADO) developers high performance and efficiency by reducing the number of intermediaries that data travels through. It also provides ADO developers with a range of data access optimizations that are specific to the Oracle database.
Download the Instant Client and Oracle ODBC driver from the Oracle website. Click the Instant Client for Microsoft Windows link and select either the 32-bit or 64-bit version that matches your PC’s platform. Once the downloaded ZIP archive has finished downloading, open it and click the Basic package hyperlink, scroll down to the SDK package, and then the ODBC ZIP. Extract all three files to a folder named Oracle.
MATLAB supports querying data from Oracle using the Microsoft ODBC Driver for Oracle. You can access the Driver from a MATLAB application by using the Database Explorer app (click Apps on the MATLAB toolbar or enter databaseexplorer at the command line). You can configure an ODBC data source either as a user DSN or as a system DSN. A user DSN is specific to the person who is logged into a machine and only this person sees the data sources that are configured on the user DSN tab. A system DSN is not specific to a person and any person who logs into the machine sees the data sources that are configured on that tab.
You can use the SQLSetConnectAttr function to set ODBC connection attributes that control behavior in an Oracle Real Application Clusters environment. For example, you can set the SQL_ORCLATTR_FAILOVER_CALLBACK attribute to return a handle to a stored procedure when a connection failure occurs in the cluster.
ODBC insulates applications from the complexity of the underlying database. It does this by presenting a standard set of API calls (the ODBC interface) to the application and by converting these requests into a form that the DBMS can understand. For example, a printer driver presents a standard set of printing commands to the system that it is connected to; it then converts these into the specific calls required by the actual hardware.
For a smoother user experience, the driver optimizes data processing and provides dynamic metadata querying. This results in accelerated performance when working with live Oracle data within Power BI.
To enable the driver to use the Oracle client directory, add it as an environment variable. Refer to Editing the System Environment Variables for more information. Once this is done, the ODBC data source will have two entries: one for the Microsoft ODBC Driver and another for the Oracle ODBC Driver. You can select either of these when creating a new ODBC data source in Power BI.
