BLOB(length, type) Streaming text or raw binary data. Specify length (column capacity), in bytes. Specify the type of BLOB column: Memo (1), Binary (2), Formatted Memo (3), OLE (4), Graphic/Binary (5). For Paradox BLOB columns, length must be between 0 and 240 (amount of data stored in .DB file); for dBASE tables between 0 and 32,767 (valid length has no practical effect on column created). Not all BLOB column types apply to all local table types or correspond to the same native column types in all table types.
