What is SQL syntax highlighting?

SQL syntax highlighting is a feature that colorizes different elements of SQL code (keywords, strings, comments, functions) to make it easier to read and understand. It helps developers quickly identify query structure, spot errors, and distinguish between different SQL components like SELECT statements, WHERE clauses, and table names.
