Open the Database Explorer app by clicking the Apps tab on the MATLAB^® Toolstrip. Then, on the right of the Apps section, click the Show more arrow to open the apps gallery. Under Database Connectivity and Reporting, click Database Explorer. Alternatively, enter databaseExplorer at the command line.

In the Data Source section, select Configure Data Source > Configure JDBC data source.

The JDBC Data Source Configuration dialog box opens.

In the Name box, enter a name for your data source. (This example uses a data source named ORA.) You use this name to establish a connection to your database.

From the Vendor list, select Oracle.

In the Driver Location box, enter the full path to the JDBC driver file.

In the Database box, enter the name of your database.

The name can be the service name or the Oracle system identifier (SID), depending on your specific Oracle database setup. For details, see your tnsnames.ora file, which is often stored in <ORACLE_HOME>/NETWORK/ADMIN, where <ORACLE_HOME> is the folder containing the installed database or the Oracle client.

In the Server box, enter the name of your database server. Consult your database administrator for the name of your database server. In the Port Number box, enter the port number. From the Driver Type list, select thin or oci. (Use thin as the default driver. Use oci if you installed an OCI driver.)

Under Connection Options, in the Name column, enter the name of an additional driver-specific option. Then, in the Value column, enter the value of the driver-specific option. Click + to specify additional driver-specific options.

Click Test. The Test Connection dialog box opens. Enter the user name and password for your database, or leave these boxes blank if your database does not require them. Click Test.

If your connection succeeds, the Database Explorer dialog box displays a message indicating the connection is successful. Otherwise, it displays an error message.

Click Save. The JDBC Data Source Configuration dialog box displays a message indicating the data source is saved successfully. Close this dialog box.

Create a JDBC data source for a Oracle database.

opts = configureJDBCDataSource("Vendor","Oracle");

Set the JDBC connection options. To set the connection options with an OCI driver, use the "DriverType" name-value pair argument. For example, this code assumes that you are connecting to a JDBC data source named ORA, database server dbtb05, port number 1521, full path of the JDBC driver file /home/user/DB_Drivers/ojdbc7.jar, and authentication type oci.

opts = setConnectionOptions(opts,"DataSourceName","ORA","Server","dbtb05", ...
    "PortNumber",1521,"JDBCDriverLocation","/home/user/DB_Drivers/ojdbc7.jar", ...
    "DriverType","oci");

To set the connection options without the OCI driver, omit the "DriverType" name-value pair argument.

To add JDBC driver-specific connection options, use the addConnectionOptions function.

Test the database connection by specifying the user name username and password pwd, or leave these arguments blank if your database does not require them.

username = "username";
password = "pwd";
status = testConnection(opts,username,password);

Save the JDBC data source.

saveAsJDBCDataSource(opts)

On the Database Explorer tab, in the Connections section, click Connect and select the data source for the connection.

In the connection dialog box, enter a user name and password, or leave these boxes blank if your database does not require them. Click Connect.

The Catalog and Schema dialog box opens.

In the Schema list, select the schema. Click OK.

The app connects to the database and displays its tables in the Data Browser pane. A data source tab appears to the right of the pane. The title of the data source tab is the data source name that you defined during the setup. The data source tab contains empty SQL Query and Data Preview panes.

Select tables in the Data Browser pane to query the database.

Close the data source tab to close the SQL query. In the Connections section, close the database connection by clicking Close Connection.

Connect to an Oracle database using the configured JDBC data source, user name username, and password pwd.

datasource = "ORA";
username = "username";
password = "pwd";
conn = database(datasource,username,password);

If you have trouble using the database function, use the full entry from your tnsnames.ora file in the URL string as one consecutive line. Leave the first argument blank. For example, this code assumes that the value of the 'URL' name-value pair argument is set to the specified tnsnames.ora file entry for an Oracle database.

conn = database('','username','pwd', ...
    'Vendor','Oracle', ...
    'URL',['jdbc:oracle:thin:@(DESCRIPTION = ' ...
    '(ADDRESS = (PROTOCOL = TCP)(HOST = sname)' ...
    '(PORT = 123456)) (CONNECT_DATA = ' ...
    '(SERVER = DEDICATED) (SERVICE_NAME = dbname) ) )']);

Close the database connection.

close(conn)
