As a registered tutor on UrbanPro.com specializing in PL/SQL Training, I'm here to guide you on creating tables using a procedure in PL/SQL.


Understanding the Basics

1. What is PL/SQL?

  • PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL.
  • It allows developers to create robust and efficient database applications.

2. Procedures in PL/SQL:

  • Procedures are reusable blocks of code that can be stored and executed in the database.
  • They enhance modularity, maintainability, and reusability of code.

Creating Tables Using a Procedure

3. Why Use Procedures for Table Creation?

  • Procedures streamline the table creation process.
  • They encapsulate the table creation logic, making it more manageable and maintainable.

4. Steps to Create Tables Using a Procedure:

  1. Define the Procedure:
    • Use the CREATE OR REPLACE PROCEDURE statement to define the procedure.
  2. Declare Variables:
    • Declare variables for table name, column names, data types, and constraints.
  3. Build the CREATE TABLE Statement:
    • Construct the CREATE TABLE statement within the procedure, specifying columns and constraints.
  4. Execute the Procedure:
    • Call the procedure to execute the table creation.

5. Sample PL/SQL Code:

plsql
CREATE OR REPLACE PROCEDURE create_table_example AS table_name VARCHAR2(50) := 'example_table'; column1 VARCHAR2(50) := 'column1_name'; column2 NUMBER := 0; BEGIN EXECUTE IMMEDIATE 'CREATE TABLE ' || table_name || ' (' || column1 || ' VARCHAR2(50), ' || column2 || ' NUMBER)'; END;

I need your help to choose my career as I have three years of gap between my education. I know SQL. Can anyone tell me should I choose MS SQL server or oracle because I am interested in the database? Which one will be better to learn to get into the IT industry? Please help me! Thank you!
As you are strong and interested in SQL, why not to choose ETL Testing? It has a good career ahead in data projects. To survive in the market, you need both Oracle & SQL Server. Actually, both are almost same but are different products.
