How to create an Oracle Insert stored procedure

In Oracle database, a stored procedure is a precompiled PL/SQL code block used to perform specific tasks. It can receive input parameters and return output values, and can execute a series of SQL statements. Stored procedures can greatly simplify complex database operations and improve database performance. This article will introduce how to create an Oracle Insert stored procedure.

Create stored procedures

In Oracle, use the CREATE PROCEDURE statement to create stored procedures. Here is a basic example:

CREATE OR REPLACE PROCEDURE sp_Insert (
  p_id NUMBER,
  p_name VARCHAR2,
  p_desc VARCHAR2
) AS
BEGIN
  INSERT INTO mytable (id, name, description)
  VALUES (p_id, p_name, p_desc);
  COMMIT;
END;

In the above example, we used CREATE OR REPLACE to create a stored procedure named sp_Insert. This stored procedure has three input parameters: p_id, p_name and p_desc. We used the INSERT INTO statement in the stored procedure to insert input parameters into the mytable table. Finally, we commit the transaction using the COMMIT statement.

Calling stored procedures

We can use the EXECUTE statement to call stored procedures. Here is an example:

EXECUTE sp_Insert(1, 'John', 'Description');

In the above example, we called the stored procedure named sp_Insert and passed three parameters to it. When the stored procedure is executed, we can see the newly inserted data rows in the mytable table.

Exception handling in stored procedures

In stored procedures, we can use the EXCEPTION statement to handle exceptions. Here is an example:

CREATE OR REPLACE PROCEDURE sp_Insert (
  p_id NUMBER,
  p_name VARCHAR2,
  p_desc VARCHAR2
) AS
BEGIN
  INSERT INTO mytable (id, name, description)
  VALUES (p_id, p_name, p_desc);
  COMMIT;
EXCEPTION
  WHEN OTHERS THEN
    ROLLBACK;
    DBMS_OUTPUT.PUT_LINE('Error: ' || SQLCODE || ' - ' || SQLERRM);
END;

In the above example, we use the EXCEPTION statement to catch any exception. When an exception occurs, we use the ROLLBACK statement to roll back the transaction, and output the abnormal SQLCODE and SQLERRM information through the DBMS_OUTPUT.PUT_LINE method.

Summary

By using the Oracle Insert stored procedure, we can greatly simplify complex database operations and improve database performance. In a stored procedure, we can use input parameters and output values, and execute a series of SQL statements. At the same time, we can also use exception handling statements to handle any abnormal situations. Of course, when creating stored procedures, we should keep good design principles in mind to ensure the effectiveness and reliability of the stored procedures.
