Class DatabaseAdaptor

  • public class DatabaseAdaptor
extends java.lang.Object
    DatabaseAdaptor Handles differences between databases. Postgres uses the getBytes and setBinaryStream methods to access a "bytea" datatype, which can be up to 1Gb of binary data. MySQL is happy to use the "blob" type and getBlob() methods instead.
