Introduction
Oracle SQL Developer is a powerful tool used by developers to work with the Oracle database. It has a console that can be used to run PL/SQL procedures and view the output of those procedures. However, if you are using Java JDBC to execute a PL/SQL procedure, you may not know how to view the output in the SQL Developer console. In this article, we will discuss how to get the Oracle SQL Developer console output in Java JDBC after executing a PL/SQL procedure.
Prerequisites
Before we proceed, make sure that you have the following:
- Oracle SQL Developer installed
- Oracle database installed
- A Java JDBC program that executes a PL/SQL procedure
Steps to Get Oracle SQL Developer Console Output in Java JDBC
- Open Oracle SQL Developer and connect to your database.
- In the SQL Worksheet, execute the PL/SQL procedure that you want to run.
- After the procedure is executed, click on the “Run” menu and select “View Log” from the drop-down menu.
- In the “Log” window, you can view the output of the procedure.
- Copy the output to your clipboard.
- In your Java JDBC program, use the following code to get the output from the clipboard and print it to the console:
String output = (String) Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.stringFlavor);
System.out.println(output);- Run your Java JDBC program and you should see the output of the PL/SQL procedure in the console.
Explanation of Steps
Let’s go through the steps in more detail.
Step 1: Connect to Your Database
Open Oracle SQL Developer and connect to your database. This is necessary to execute the PL/SQL procedure and view the output.
Step 2: Execute the PL/SQL Procedure
In the SQL Worksheet, execute the PL/SQL procedure that you want to run. You can do this by typing the procedure in the worksheet and clicking on the “Run Script” button or by using the shortcut key “F5”.
Step 3: View the Log
After the procedure is executed, click on the “Run” menu and select “View Log” from the drop-down menu. This will open the “Log” window where you can view the output of the procedure.
Step 4: View the Output
In the “Log” window, you can view the output of the procedure. You can select the output and copy it to your clipboard.
Step 5: Get the Output in Java
In your Java JDBC program, use the following code to get the output from the clipboard and print it to the console:
String output = (String) Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.stringFlavor);
System.out.println(output);This code gets the data from the clipboard and converts it to a string. It then prints the string to the console.
Step 6: Run Your Java JDBC Program
Run your Java JDBC program and you should see the output of the PL/SQL procedure in the console.
Conclusion
In this article, we have discussed how to get the Oracle SQL Developer console output in Java JDBC after executing a PL/SQL procedure. By following the steps outlined in this article, you can easily view the output of your PL/SQL procedures in the SQL Developer console from your Java JDBC program. This can be very helpful when debugging your code or monitoring the output of your procedures.
