This document contains a list of SQL keywords organized into different categories such as data types, operators, functions, and constraints. It includes common data types like string, numeric, and date/time. It also lists various SQL operators for arithmetic, relational, logical, and assignment operations. Functions are categorized as numeric, string, and date/time. Keywords are grouped according to data definition language (DDL), data manipulation language (DML), and constraints. Select, insert, update, and delete keywords are specified under DML categories.
