SQL Secrets Unleashed: Master Your Data Mission, Transporter-Style

Welcome to the thrilling world of SQL queries, where you’ll embark on an adventure reminiscent of the Transporter movies, but with a twist — instead of driving fast cars, you’ll be navigating databases at lightning speed! In this SQL tutorial, we’ll uncover the secrets of your database tables and learn how to list column information, just like Frank Martin, our SQL transporter extraordinaire.

Scenario 1: Listing Information for All Columns in a Table (Frank’s Full Inventory Check)

In a high-stakes mission, Frank Martin has been assigned to retrieve information about all the columns in a specific table, just like you in SQL. He needs to know everything — from the names of the columns to their data types. Here’s how Frank (and you) would do it:

-- Frank's Full Inventory Check
SELECT
    COLUMN_NAME,
    DATA_TYPE,
    CHARACTER_MAXIMUM_LENGTH
FROM
    INFORMATION_SCHEMA.COLUMNS
WHERE
    TABLE_NAME = 'YourTableName';

• COLUMN_NAME: Frank wants to know the names of all columns, just like checking the names of the packages he transports.
• DATA_TYPE: Just like Frank needs to know what's inside each package, you'll find the data type of each column.
