Class HibernateAlterTableExecutor

java.lang.Object
  extended by com.atlassian.confluence.upgrade.ddl.HibernateAlterTableExecutor
All Implemented Interfaces:
AlterTableExecutor

public class HibernateAlterTableExecutor
extends Object
implements AlterTableExecutor

Executes all the various database-specific table altering commands. PLEASE READ: Due to CONFDEV-7957 (and until HSQLDB addresses their concurrency issues), any upgrade tasks that composes this executor must be wrapped in a transaction proxy with REQUIRES_NEW propagation.

Since:
4.0

alterTable

public void alterTable(String tableName,
                       List<? extends AlterTableCommand> commands)
Description copied from interface: AlterTableExecutor
Perform a set of table altering actions on a given table. On some databases such as PostgreSQL this is combined into a single statement automatically. On other databases such as HSQLDB, each alter action is executed as a separate statement.

Specified by:
alterTable in interface AlterTableExecutor
Parameters:
tableName - Name of the table to alter
commands - A collection of alter table actions to perform

getAlterTableStatements

public List<String> getAlterTableStatements(String tableName,
                                            List<? extends AlterTableCommand> commands)
Specified by:
getAlterTableStatements in interface AlterTableExecutor
