Method Summary

Modifier and Type	Method and Description
Sql[]	generateSql(AddDefaultValueStatement statement, Database database, SqlGeneratorChain sqlGeneratorChain) Generate the actual Sql for the given statement and database.
boolean	generateStatementsIsVolatile(Database database) Does this change require access to the database metadata? If true, the change cannot be used in an updateSql-style command.
int	getPriority() Of all the SqlGenerators that "support" a given SqlStatement/Database, SqlGeneratorFactory will return the one with the highest priority.
boolean	supports(AddDefaultValueStatement statement, Database database) Does this generator support the given statement/database combination? Do not validate the statement with this method, only return if it can support it.
ValidationErrors	validate(AddDefaultValueStatement statement, Database database, SqlGeneratorChain sqlGeneratorChain) Validate the data contained in the SqlStatement.

                                 SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

Validate the data contained in the SqlStatement. If there are no errors, return an empty ValidationErrors object, not a null value. Liquibase will inspect the ValidationErrors result before attempting to call generateSql.

Specified by:

validate in interface SqlGenerator<AddDefaultValueStatement>

Overrides:

validate in class AddDefaultValueGenerator

getPriority

public int getPriority()

Description copied from interface: SqlGenerator

Of all the SqlGenerators that "support" a given SqlStatement/Database, SqlGeneratorFactory will return the one with the highest priority.

Specified by:

getPriority in interface PrioritizedService

                        Database database)

Description copied from interface: SqlGenerator

Does this generator support the given statement/database combination? Do not validate the statement with this method, only return if it can support it.
