metaData - The JDBC metadata.

Returns:

The dialect to use, or null.

resolveDialectInternal

protected abstract Dialect resolveDialectInternal(java.sql.DatabaseMetaData metaData)
                                           throws java.sql.SQLException

Perform the actual resolution without caring about handling SQLExceptions.
