Field Summary

Fields
Modifier and Type	Field and Description
`static boolean`	`DEFAULT_ALLOW_COLUMN_DROP` By default don't allow column drops.
`static int`	`DEFAULT_BLOB_BUFFER_SIZE` The default buffer size for blobs.
`static int`	`DEFAULT_CHECK_CONNECTION_TIMEOUT` The default timeout when checking if a connection is down.
`static boolean`	`DEFAULT_COMPRESS_LOBS` Indicates if the LOB columns should be compressed.
`static boolean`	`DEFAULT_DISABLE_LOB_CACHING` Indicates if LOB data caching should be disabled, to avoid consuming too much memory and/or disk space in the DB server.

    Constant Field Values
  - SQL_STATE_TRANSACTION_FAILURE
```
public static final String SQL_STATE_TRANSACTION_FAILURE

    Constant Field Values
  - SQL_STATE_UNIQUE_CONSTRAINT_VIOLATION
```
public static final String SQL_STATE_UNIQUE_CONSTRAINT_VIOLATION
