Method Detail

populate

void populate(Connection connection)
       throws SQLException,
              ScriptException

Populate, initialize, or clean up the database using the provided JDBC connection.

Concrete implementations may throw an SQLException if an error is encountered but are strongly encouraged to throw a specific ScriptException instead. For example, Spring's ResourceDatabasePopulator and DatabasePopulatorUtils wrap all SQLExceptions in ScriptExceptions.

Parameters:

connection - the JDBC connection to use to populate the db; already configured and ready to use; never null

Throws:

SQLException - if an unrecoverable data access exception occurs during database population

ScriptException - in all other error cases
