Query statements, also
known as Data Query Language (DQL) statements, are the primary method to
analyze data in Cloud Spanner. They scan one or more tables or
expressions and return the computed result rows.
Data Definition Language (DDL) statements
let you create and modify database objects such as tables, views, and database roles.
Data Manipulation Language (DML) statements
enable you to update, insert, and delete data from your
Cloud Spanner tables.
Data Access Control statements
let you grant and revoke access privileges at the table and column level.
Transaction Control statements
allow you to manage transactions for data modifications.
