This document contains a summary of column types, functions, operators and other elements that can be used in SQL queries. It includes data types like strings, numbers, dates and times. It also lists comparison, logical and string functions that can be used in SELECT statements, WHERE clauses and other parts of a query. The document provides information on JOINs, UPDATEs, DELETEs and other SQL statements.
