public interface SqlStatement

The SqlStatement classes correspond to (roughly) a single SQL statement. SqlStatement instances are created by Change classes, and by Liquibase itself as the primary database-independent abstraction of statements to execute against a database.

A single SqlStatement may yield multiple SQL commands, and may yield a different number of SQL commands depending on the database. If a particular statement. The SqlStatement implementations do not actually generate SQL strings, that is left to the SqlGenerator implementations. Instead, the purpose of the SqlStatement implementation is to hold the metadata required to generate the correct SQL for a particular database at a later time.
