BLOBs Handling

When fetching long string values or binary data, there are methods that you can use to fetch the data in pieces.

For binary data, use the GetBytes method, and for string data, use the GetChars method. Otherwise, BLOB data is treated in the same manner as any other data you fetch from the database.
