Best way to export a BLOB

Toad for Oracle
1

I have the table who’s script is below.

Do you have a recommendation for exporting the BLOB.

If you look at the screen shot you will see the keys alonmg with the name of the file that is in the BLOB.

Any suggestions?

CREATE TABLE MRRDBO.MRR_NOTES_ATTACH

(

I_NOTES NUMBER NOT NULL,

I_ATTACH NUMBER NOT NULL,

T_ATTACH BLOB,

N_FILE VARCHAR2(255 BYTE),

N_DIR VARCHAR2(255 BYTE),

N_CREAT_BY VARCHAR2(30 BYTE) DEFAULT user,

D_CREAT DATE DEFAULT sysdate,

N_ORA_DB_USER VARCHAR2(30 BYTE) DEFAULT user NOT NULL,

S_ROW_UPD DATE DEFAULT sysdate NOT NULL,

C_ATTACH_TYPE VARCHAR2(256 BYTE),

N_ATTACH_DESC VARCHAR2(256 BYTE)

Do you have a recommendation for exporting the BLOB.

Do you mean only BLOB columns or the whole table with BLOBs?

If only BLOB column, is it one record or many of them?

One column, double click and then save the content to a file with proper extension.
