FILEOPEN first open the file
Then FILEREAD read the file
Then UPDATEBLOB upload file
This request must before already insert the data in the database clock, just file fields of space and time,
Int fh
Blob Emp_id_pic
Fh=FileOpen (" c: \ emp_100 BMP, "StreamMode!)
IF fh & lt;> 1 THEN
FileRead (fh, emp_id_pic)
FileClose (fh)
UPDATEBLOB Employee SET emp_pic=: Emp_id_pic
WHERE Emp_num=100;
COMMIT;
END the IF
