This tutorial shows how to set up a data source and connect to an Oracle® database using the Database Explorer app or the command line. This tutorial uses the Oracle Database 11g Release 2 (220.127.116.11) JDBC driver for use with JDK™ 1.6 to connect to an Oracle 11g Enterprise Edition Release 18.104.22.168.0 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 set up a data source using the Database Explorer app or 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.
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
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. In the Server box, enter the name of your database server. Consult your database administrator for the name of your database server.
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 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
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
path of the JDBC driver file
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
Test the database connection by specifying the user name
username and password
leave these arguments blank if your database does not require
username = "username"; password = "pwd"; status = testConnection(opts,username,password);
Save the JDBC data source.
After you complete the data source setup, connect to the Oracle database using the Database Explorer app or the JDBC driver and command line.
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.
If multiple connections are open, close the database connection of your choice by selecting the corresponding data source from the Close Connection list.
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.
