SQL data types classify data into string, numeric, and date/time categories. String types store text, numeric types store numbers, and date/time types store dates and times. Examples of SQL string types include VARCHAR for variable-length strings and CHAR for fixed-length strings. Numeric types comprise INTEGER for whole numbers and DECIMAL for numbers with decimals. DATE stores dates and DATETIME stores dates with times. Proper use of these data types helps ensure accurate storage and retrieval of data in database tables.
