How to Run Stored Procedure In Oracle?

To run a stored procedure in Oracle, you can use the EXECUTE statement or the EXEC keyword followed by the name of the procedure and any necessary parameters. You can also use the CALL statement followed by the procedure name.

For example, if you have a stored procedure called "my_procedure" that takes two parameters, you can run it using the following syntax:

EXECUTE my_procedure(parameter1, parameter2);

or

EXEC my_procedure(parameter1, parameter2);

Alternatively, you can use the CALL statement like this:

CALL my_procedure(parameter1, parameter2);

Make sure you have the necessary privileges to execute the stored procedure and provide the correct parameters in the order they are defined in the procedure.

How to grant execute permission on a stored procedure in Oracle?

To grant execute permission on a stored procedure in Oracle, you can use the following syntax:

1

GRANT EXECUTE ON procedure_name TO user_name;

Replace procedure_name with the name of your stored procedure and user_name with the name of the user or role that you want to grant execute permission to.

For example, if you want to grant execute permission on a stored procedure called my_proc to a user named john, you would use the following command:

1

GRANT EXECUTE ON my_proc TO john;

After executing this command, the user john will be able to execute the stored procedure my_proc.

How to alter a stored procedure in Oracle?

To alter a stored procedure in Oracle, you can use the following steps:

1. Connect to your Oracle database using a SQL client or command-line tool.
2. Use the following SQL command to alter the stored procedure:

1
2

ALTER PROCEDURE procedure_name 
{COMPILE | RECOMPILE}

Replace procedure_name with the name of the stored procedure you want to alter.

1. If you want to modify the code of the stored procedure, you can use the CREATE OR REPLACE PROCEDURE command to redefine the stored procedure with the new code. For example:

1
2
3
4
5

CREATE OR REPLACE PROCEDURE procedure_name 
IS
BEGIN
-- new code here
END;

1. Once you have made the necessary changes to the stored procedure, you can recompile it using the ALTER PROCEDURE command as shown in step 2.
2. Confirm that the stored procedure has been altered successfully by testing it with sample input data.

By following these steps, you can alter a stored procedure in Oracle and make changes to its code or behavior as needed.

How to execute a stored procedure in Oracle SQL Developer?

To execute a stored procedure in Oracle SQL Developer, follow these steps:

1. Open Oracle SQL Developer and connect to your database.
2. In the Connections panel, expand the database node and navigate to the Procedures folder.
3. Find the stored procedure you want to execute in the list of procedures.
4. Right-click on the stored procedure and select "Run".
5. A dialog box will open, allowing you to enter any required input parameters for the stored procedure.
6. Click "OK" to execute the stored procedure.
7. You can view the results of the stored procedure execution in the Script Output panel at the bottom of the SQL Developer window.

Alternatively, you can also execute a stored procedure using a SQL query. For example, you can use the following syntax to execute a stored procedure named "my_procedure":

1
2
3

BEGIN
  my_procedure();
END;

After executing the above SQL query, the stored procedure "my_procedure" will be executed.

How to create a stored procedure in Oracle SQL Developer?

To create a stored procedure in Oracle SQL Developer, follow these steps:

1. Open Oracle SQL Developer and connect to your database.
2. In the left-hand side panel under the "Connections" tab, expand your database connection and navigate to the "Procedures" folder.
3. Right-click on the "Procedures" folder and select "New Procedure" from the context menu.
4. In the "Create Procedure" window, enter a name for your stored procedure and write the PL/SQL code for your stored procedure in the main text area.
5. Once you have written your PL/SQL code, click on the "Compile" button to check for any syntax errors in your code.
6. If there are no syntax errors, click on the "Compile for Debugging" button to finalize the creation of your stored procedure.
7. Your stored procedure is now created and can be found under the "Procedures" folder in your database connection. You can edit, compile, and run your stored procedure from here.

That's it! You have successfully created a stored procedure in Oracle SQL Developer.

How to execute a stored procedure with output parameters in Oracle?

To execute a stored procedure with output parameters in Oracle, you need to follow these steps:

1. Define the stored procedure with output parameters in your Oracle database. Here is an example of a stored procedure with output parameters:

1
2
3
4
5
6
7
8

CREATE OR REPLACE PROCEDURE get_employee_details (emp_id IN NUMBER, emp_name OUT VARCHAR2, emp_salary OUT NUMBER)
IS
BEGIN
   SELECT name, salary 
   INTO emp_name, emp_salary
   FROM employees
   WHERE employee_id = emp_id;
END;

1. In your SQL client or IDE, you can execute the stored procedure by calling it and passing the input parameters and output parameters using the EXECUTE or CALL statement. Here is an example of calling the get_employee_details stored procedure:

1
2
3
4
5
6
7
8

DECLARE
   v_emp_name VARCHAR2(50);
   v_emp_salary NUMBER;
BEGIN
   get_employee_details(100, v_emp_name, v_emp_salary);
   DBMS_OUTPUT.PUT_LINE('Employee Name: ' || v_emp_name);
   DBMS_OUTPUT.PUT_LINE('Employee Salary: ' || v_emp_salary);
END;

1. Once you execute the above code, the stored procedure will be called with the input parameter emp_id as 100. The output parameters emp_name and emp_salary will be populated with the corresponding values from the employees table, and the results will be displayed using the DBMS_OUTPUT.PUT_LINE statements.
2. You can also execute the stored procedure in a SQL script or PL/SQL block to retrieve and process the output parameters as needed.

How to monitor the performance of a stored procedure in Oracle?

There are several ways to monitor the performance of a stored procedure in Oracle:

1. Use Oracle Enterprise Manager (OEM): Oracle Enterprise Manager provides a graphical user interface for monitoring and managing Oracle databases. You can use OEM to monitor the performance of stored procedures by viewing system metrics, performance data, and SQL execution statistics.
2. Use Oracle SQL Developer: Oracle SQL Developer is a free graphical tool for database development and management. You can use SQL Developer to view and analyze execution plans, query statistics, and performance data for stored procedures.
3. Use Oracle Trace: You can enable tracing for a specific session or for the entire database to capture detailed performance data for stored procedures. This can help you identify performance bottlenecks and optimize the execution of your stored procedures.
4. Use Oracle Performance Tuning tools: Oracle provides various performance tuning tools such as SQL Tuning Advisor, SQL Access Advisor, and SQL Performance Analyzer. These tools can help you analyze and optimize the performance of your stored procedures.
5. Use Oracle AWR (Automatic Workload Repository) reports: AWR reports provide a detailed analysis of database performance over time. You can use AWR reports to monitor the performance of stored procedures and identify performance trends and issues.

Overall, monitoring the performance of a stored procedure in Oracle involves analyzing SQL execution plans, query statistics, system metrics, and other performance data to optimize the execution of the stored procedure and improve overall database performance.
