SQL LIKE

SQL LIKE is a pattern-matching operator used in SQL queries to search for specified patterns in text columns. It allows for flexible string matching using wildcard characters, such as '%' for any sequence of characters and '_' for a single character. This operator is essential for performing partial or fuzzy searches in databases, enabling users to find records based on incomplete or variable text data.

Also known as: LIKE operator, SQL pattern matching, wildcard search, text search in SQL, fuzzy search SQL

Why learn SQL LIKE?

Developers should learn SQL LIKE when building applications that require search functionality, such as filtering user inputs, implementing autocomplete features, or querying logs and reports. It is particularly useful in scenarios where exact matches are not feasible, like searching for names with variations, product descriptions, or email addresses with common domains. Mastering LIKE helps optimize data retrieval in relational databases like MySQL, PostgreSQL, or SQL Server.
