If you install your own database, consult the documentation for the driver for information on installation and any other environment settings you need for your platform.

The Statement object has methods for executing SQL queries and updates.
Again, this is specific to bit Windows; you might need to do some research to figure it out for your own platform. The driver file must be copied to the latter folder if you are running multiple domains and wish to specify a driver for each domain.
Check with your driver vendor for what is supported.
Connections to other databases will involve similar steps and code. The database striny specified in your projects need to be installed on both the Enterprise Designer machine and the Logical host machine. Drivers are uniquely different in what they do and the type of functions they support.
Run the applet again, this time with a policy file named DbaApplPol that has the above permission in it:. A final variable contains sun.jdbc.odbc.jdbcodncdriver constant value that can never change once it is initialized.

To successfully run, the DbaAppl. Single quotes are prepended and appended to comply with SQL syntax. Making these changes and turning the SQL statement into a dynamically-created String produces: The query that I created using Microsoft Query not only showed me that my dtring was there and in good order, but it also automatically created the SQL code that I needed to insert into my Java program. However, if you run the applet without a policy file, you get a stack trace indicating permission errors.
SocketPermission “developer”, “resolve”; “accessClassInPackage. It includes the following sections: You need a table with one text field for storing character data.
Your connection string doesn’t seem right, the syntax highlighting is off.
Each applet has its own policy file with different permission lists and has different requirements for locating the database driver.
Here is the DbaAppl.

For this query, it looked like this: Here is the DbaApplPol policy file with the permission indicated by the stack trace added to it:. In fact, the load statement above for the jdbc-odbc driver sun.jdbc.odbc.jbcodbcdriver only one that actually comes with JDK 1.
This example converts the FileIO program from Lesson 6 to write data to xtring read data from a database. A private variable can only be used accessed by the class in which it is declared. Remember to ensure that the input parameter data types match the data types specified in the database table targeted by the Prepared Statements as some drivers always return the data type as a string.

I also wanted to display only those names that had email addresses associated with them. The Exception Handling section in Lesson 6 describes try and catch blocks.
To retrieve the data returned, the code iterates through the ResultSetretrieves the data, and appends the data to the text area, displayText. Note that other query tools are also available from other vendors.
