alterTable

void alterTable(String tableName,
                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

List<String> getAlterTableStatements(String tableName,
                                     List<? extends AlterTableCommand> commands)
