3.1 Defining queries using CQL

You use CQL to define queries. CQL uses the following items (basic items) to define processing:

A keyword is a character string that specifies a data-processing function, such as SELECT and WHERE. The numeric values, delimiters, names, and constants that are used to define processing targets and processing ranges for a keyword are called operands.

When specifying these basic items, you must pay attention to the characters and data types that can be used.

This section explains the format of the basic items and the characters that can be used when using CQL for defining queries. It also explains the symbols used in the explanation of CQL syntax provided later.
