Hi to all,
I'm using adodb for accessing mysql and postgres. My problem relies on
the mysql access.
Sometimes, when I try to execute a query (using ExecTrans method
below), I get this error:
'NoneType' object has no attribute 'cursor'
Maybe this error ocurrs not in my code, but in the mysql module. Does
anyone had had this problem?
Thanks.
The following is my DB connection class.
class DB:
def __init__(self, host=None, user=None, password=None,
database=None):
self.host =
[host,variables. IP_DB][isinstance(host ,(types.NoneTyp e))]
self.user =
[user,variables. USER][isinstance(user ,(types.NoneTyp e))]
self.password =
[password,variab les.PASSWORD][isinstance(pass word,(types.Non eType))]
self.database =
[database,variab les.DATABASE][isinstance(data base,(types.Non eType))]
self.bActive = True
self.bConnected = False
def OpenDB(self):
success = False
if self.bActive:
try:
self.conn = adodb.NewADOCon nection('mysql' )
if not self.conn:
Log.log("Can't connecto to DB-Mysql")
success = False
else :
#Create the connection
ret = self.conn.Conne ct(self.host, self.user,
self.password, self.database)
if ret:
Log.log("DB-Mysql connection stablished")
success = True
except:
success = False
pass
else:
print "DB connection disabled"
self.bConnected = success
return success
def Exec(self,query ,simple=False):
resultado = list()
#Open a DB connection
if self.OpenDB():
Log.log("Execut ing Query: " + str(query))
cursor = self.conn.Execu te(query)
if cursor:
while not cursor.EOF:
if not simple:
resultado.appen d(cursor.GetRow Assoc())
cursor.MoveNext ()
else :
resultado.appen d(cursor.FetchR ow())
#Close Cursor
cursor.Close()
else:
resultado = None
self.CloseDB()
else:
resultado = None
return resultado
def ExecTrans(self, lQueries):
success = False
if self.OpenDB():
print "Executing Querys: " + str(lQueries)
#Begin Transaction
self.conn.Begin Trans()
#Execute each query in lQueries
for query in lQueries:
self.conn.Execu te(query)
if self.conn._errn o != 0 :
success = False
break;
else:
success = True
#End of transaction
if success:
self.conn.Commi tTrans()
else:
self.conn.Rollb ackTrans()
#Closing DB
self.CloseDB()
return success
def TestConnection( self):
if self.OpenDB():
self.CloseDB()
return True
return False
def CloseDB(self):
if self.conn.IsCon nected() :
self.conn.Close ()

Hi all,
I've taken on a massive project for a client recently and now I've hit
some bug fixes that are required (3rd party code). and was just wondering
about peoples opinions / personal findings.
This set of scripts for the section of the project use an ADODB class for
MySQL. I've never used this method before (I wrote a class a while back to
handle my MySQL core code which was mainly a wrapper for various mysql_*()
functions etc)....

Hi,
I discovered adodb and is use it now in order to connect from PHP to ms
Access under Windows. No problem.
Is this also applicable to PHP under linux, because i get a lot of errors
like:
include('../adodb/adodb.inc.php'); ---->"permission denied"
$conn = 'Provider=Microsoft.Jet.OLEDB.4.0;'. 'Data

Fixing Multiple Database bug in adoDB
popular data access layer for php, adoDB can support multiple databases
from different provider at time, but not from same provider. what I

simple question that I haven't been able to quite pinpoint an answer
to.
I'm used to using the native mysql functions with

the execute method or should I take my own steps to sanitize input
data?
Also, one of the reasons I'm looking at ADOdb is I'd like to start to

I encrypted a database field using MySQL AES_ENCRYPT() from a mysql command
prompt. But I need to encrypt and decrypt at will in the php code as
records are added and viewed.
I can easily decrypt it because the code specifies a Query. But the INSERT
is an ADODB insert:
$_POST = 83;
....
runQuery($db ->GetInsertSQL($rs, $_POST, true));

I have encountered a problem when querying a table.
The query passed data into a recordset which should have resulted in many records but has returned EOF.
After debugging the code the only solution i have found is that i have set the recordset to NEW ADODB.RECORDSET two times before actually perfoming the rs.open (once in the main program and once in the dll which contains the loadrecords function).
