mysqldb duplicate entry error handling

[baur79]

Hi guys


i try to run this code in loop and to pass even the entry is
duplicated

def email_insert_in _db(email):
sql="INSERT INTO emails (email) values ('%s') "%(email)
db=_mysql.conne ct(host = "localhost" , user = db_user, passwd =
db_pass, db = db_name)

try:
db.query(sql)
except IndentationErro r:
print "duplicate"
pass

also try to (raise, continue)
but can't continue in loop

error output is:
File "inser_in_db.py ", line 85, in email_insert_in _db
db.query(sql)
IntegrityError: (1062, "Duplicate entry 'email@domain.c om' for key 1")

thanks for your help

If you want to catch IntegrityError, why are you actually catching
IndentationErro r?

except IntegrityError, NameError:
NameError: global name 'IntegrityError ' is not defined

IntegrityError will most likely be defined in the namespace of
whatever you're using for MySQL access.

So show us the schema for the database... My take: Your database
ALREADY HAS a record with that "email@domain.c om" value AND emails.email
is defined as a unique key field.

Right. That's not a bug; it's supposed to do that when you try
to add a duplicate. What do you want to happen?

If you want to allow duplicates, remove the UNIQUE on that
field from the schema.

If you want the new entry to replace the old entry, use REPLACE
instead of INSERT.

If you just want to detect the problem, provide

import MySQLdb
kmysqlduplicate entry = 1062 # MySQL error code when INSERT finds a duplicate
try :
... # do INSERT
except MySQLdb.Integri tyError, message:
errorcode = message[0] # get MySQL error code
if errorcode == kmysqlduplicate entry : # if duplicate
... # handle duplicate
else:
raise # unexpected error, reraise
