I am using MS Access to import the table information. Table is below:
Field1 Field2
U1a14 High Speed Link
U0001 Medium speed data
U0022 Low Speed Link
My code value is like: code = U1a14 code = U0001 code = B11DB (This code is not present in table)
I am connecting to odbc and searching for code in table.
connection = pypyodbc.connect('DRIVER={Microsoft Access Driver (*.mdb)};UID=admin;UserCommitSync=Yes;SafeTransactions=0;MaxScanRows=8;MaxBufferSize=2048;FIL={MS Access};DriverId=25;DefaultDir=C:\PYTHON27;DBQ=C:\PYTHON27\iso14229dtcs.mdb;')
cursor1 = connection.cursor()
cursor1.execute("SELECT Field2 FROM Table Where Field1 = '{}'".format(code))
for row in cursor1.fetchone():
print row
I am getting error:
error:
for row in cursor1.fetchone():
TypeError: 'NoneType' object is not iterable
How Can I fix it, If the code is not present in my Table, it should skip and print only existing row
Change the code to the following, check cursor1.fetchone()
is not NULL.
connection = pypyodbc.connect('DRIVER={Microsoft Access Driver (*.mdb)};UID=admin;UserCommitSync=Yes;SafeTransactions=0;MaxScanRows=8;MaxBufferSize=2048;FIL={MS Access};DriverId=25;DefaultDir=C:\PYTHON27;DBQ=C:\PYTHON27\iso14229dtcs.mdb;')
cursor1 = connection.cursor()
cursor1.execute("SELECT Field2 FROM Table Where Field1 = '{}'".format(code))
row = cursor1.fetchone()
while row is not None:
print row[0], row[1]
row = cursor1.fetchone()
cursor1.close()
connection.close()
