java.lang.Objectliquibase.change.AbstractChange
liquibase.change.AbstractSQLChange
public abstract class AbstractSQLChange
A common parent for all raw SQL related changes regardless of where the sql was sourced from. Implements the necessary logic to choose how the SQL string should be parsed to generate the statements.

public boolean supports(Database database)
SqlGenerator.supports(liquibase.statement.SqlStatement, liquibase.database.Database)
method on the SqlStatement
objects returned by Change.generateStatements(liquibase.database.Database)
.
If no or null SqlStatements are returned by generateStatements then this method returns true.
If AbstractChange.generateStatementsVolatile(liquibase.database.Database)
returns true, we cannot call generateStatements and so assume true.
