CQL lexical structure

CQL input consists of statements that change data, look up data, store data, or change the way data is stored.

CQL input consists of statements. Like SQL, statements change data, look up data, store data, or change the way data is stored. Statements end in a semicolon (;).

For example, the following is valid CQL syntax:

SELECT * FROM MyTable;

UPDATE MyTable
  SET SomeColumn = 'SomeValue'
  WHERE columnName = B70DE1D0-9908-4AE3-BE34-5573E5B09F14;

This is a sequence of two CQL statements. This example shows one statement per line, although a statement can usefully be split across lines as well.
