This tutorial shows how to set up a data source and connect to a Oracle® database using the Database Explorer app or the command line. This tutorial uses the Oracle Database 11g Release 2 (126.96.36.199) JDBC driver for use with JDK™ 1.6 to connect to a Oracle 11g Enterprise Edition Release 188.8.131.52.0 database.
If the JDBC driver for Oracle is not installed on your computer, find the link on the Driver Installation page to install the driver. Follow the instructions to download and install this driver on your computer.
You can set up a data source using the JDBC Data Source Configuration dialog box, which you can open from the Database Explorer app or at the command line.
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.
configureJDBCDataSource at the command
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
To use the full entry from your
OTHER instead and enter the full entry
in the resulting URL box. Then, enter the full path
to the JDBC driver file in the Driver Location box
and the name of the driver in the resulting Driver
box. Save the JDBC data source. For details about these steps, see Other ODBC-Compliant or JDBC-Compliant Databases.
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> 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 as the default driver. Use
oci if you installed an OCI driver.)
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.
After you complete the data source setup, connect to the Oracle database using the Database Explorer app or JDBC driver and command line.
On the Database Explorer tab, in the Data Source section, click New Query.
In the Connect to a Data Source dialog box, select the data source you defined from the Data Source list. 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 Database Explorer app connects to the database and displays database 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 and the database connection.
To close the database connection, close all tabs that have titles
beginning with the name of the corresponding data source. For
example, if the data source name is
ORA, and two
open, then close both tabs.
To close all database connections, close the Database Explorer app.
Connect to an Oracle database using the configured JDBC data source, user name
username, and password
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
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.
