SQL
Advanced Text Search with LIKE Across Multiple Columns
Learn how to perform effective text searches across multiple database columns using the SQL LIKE operator and OR conditions for robust filtering.
SELECT id, product_name, description, category
FROM products
WHERE product_name LIKE '%search_term%'
OR description LIKE '%search_term%'
OR category LIKE '%search_term%';
How it works: This query demonstrates how to search for a specific `search_term` across multiple text-based columns (`product_name`, `description`, `category`) within the `products` table. The `LIKE` operator combined with the wildcard `%` matches partial strings, and `OR` combines the conditions to find a match in any of the specified columns, useful for basic search functionality.
