Integers in SQL are numeric data types used to store whole numbers without decimal points. They come in various sizes and ranges, including `INT`, `SMALLINT`, `BIGINT`, and `TINYINT`. Each type has its own storage requirements and range of values. Integers are commonly used for fields that require counting, indexing, or storing numerical identifiers. Understanding integer types is crucial for optimizing storage and ensuring data integrity in SQL databases.
