私の2番目のデータフレームは値をロードしていません。なぜそれが動作していないとどんな助け?私のカーソルをリストにすると、その中にはたくさんの値が入っていますが、何らかの理由で、通常のデータフレームをパンダで2度読み込もうとすると、動作しません。2番目のデータフレームを作成できませんpandas
マイコード:
conn = pyodbc.connect(constr, autocommit=True)
cursor = conn.cursor()
secondCheckList = []
checkCount = 0
maxValue = 0
strsql = "SELECT * FROM CRMCSVFILE"
cursor = cursor.execute(strsql)
cols = []
SQLupdateNewIdField = "UPDATE CRMCSVFILE SET NEW_ID = ? WHERE Email_Address_Txt = ? OR TELEPHONE_NUM = ? OR DRIVER_LICENSE_NUM = ?"
for row in cursor.description:
cols.append(row[0])
df = pd.DataFrame.from_records(cursor)
df.columns = cols
newIdInt = 1
for row in range(len(df['Email_Address_Txt'])):
#run initial search to figure out the max number of records. Look for email, phone, and drivers license, names have a chance not to be unique
SQLrecordCheck = "SELECT * FROM CRMCSVFILE WHERE Email_Address_Txt = '" + str(df['Email_Address_Txt'][row]) + "' OR TELEPHONE_NUM = '" + str(df['Telephone_Num'][row]) + "' OR DRIVER_LICENSE_NUM = '" + str(df['Driver_License_Num'][row]) + "'"
## print(SQLrecordCheck)
cursor = cursor.execute(SQLrecordCheck)
## maxValue is indeed a list filled with records
maxValue =(list(cursor))
## THIS IS WHERE PROBLEM OCCURS
tempdf = pd.DataFrame.from_records(cursor)
カーソルは何を出力しますか? –
