mysql - Python - MySQLdb: ValueError - unsupported format - although the use of the execute substitution -

-

i'm trying update blob images in database python-mysqldb package error:

valueerror: unsupported format character ',' (0x2c) @ index 64

i've added images time ago execute substitution tools example this:

set connection db:

db  = mysqldb.connect( host="127.0.0.1", port=0815, user="javert", passwd="ureyes", db="some_db")  cur = db.cursor()

read image files:

images = [ open( image_file, 'rb') image_file in folder ] image1, ..., image6 = images

insert images:

command = """insert database_table (column1, ..., column6) values (%s,%s,%s,%s,%s,%s)""" cur.execute( command, args=( image1, ..., image6)) db.commit()

now i've replaced insert command following , described error:

"""update database_table set column1=%s, column2=%s, column3=%s, column4=s%, column5=%s, column6=%s id=table_row_id"""

thank help!

column4=s%, should column4=%s, (note inverted , , s).

observe error message says (, isn't appropriate "format character"): "format character" comes after %, , , not valid one.
