Method Detail

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
Specified by:
getPriority in interface SqlGenerator<TableRowCountStatement>
Overrides:
getPriority in class AbstractSqlGenerator<TableRowCountStatement>

supports

public boolean supports(TableRowCountStatement statement,
                        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 suppot it.

Specified by:
supports in interface SqlGenerator<TableRowCountStatement>
Overrides:
supports in class AbstractSqlGenerator<TableRowCountStatement>

validate

public ValidationErrors validate(TableRowCountStatement dropColumnStatement,
                                 Database database,
                                 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.


generateCountSql

protected String generateCountSql(TableRowCountStatement statement,
                                  Database database)

generateSql

public Sql[] generateSql(TableRowCountStatement statement,
                         Database database,
                         SqlGeneratorChain sqlGeneratorChain)
Description copied from interface: SqlGenerator
Generate the actual Sql for the given statement and database.
