Interface AlterTableExecutor

All Known Implementing Classes:

HibernateAlterTableExecutor

public interface 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

Method Detail

                                                                 java.lang.String oldDataType,

createAddUniqueConstraintCommand

AddUniqueConstraintCommand createAddUniqueConstraintCommand(java.lang.String constraintName,
                                                            java.lang.String... columnNames)

createDropUniqueConstraintCommand

alterTable

void alterTable(java.lang.String tableName,
                java.util.List<? extends AlterTableCommand> commands)

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.

Parameters:

tableName - Name of the table to alter

commands - A collection of alter table actions to perform

getAlterTableStatements

java.util.List<java.lang.String> getAlterTableStatements(java.lang.String tableName,
                                                         java.util.List<? extends AlterTableCommand> commands)
