MySQL 错误消息：“1054 (42S22)：‘字段列表’中的未知列‘inf’”

Question

"errorMessage": "1054 (42S22): Unknown column 'inf' in 'field list'"

我不确定此错误消息的来源在哪里。 它指向mycursor.executemany(sql, all_data) ，它告诉我数据有问题？ 首先，我试图理解这意味着什么。 有人可以分解吗？

该脚本相当广泛，但我显示了插入数据的部分。

                    # Create DataFrame
                df = pd.DataFrame({"date": date, "open": open, "high": high, "low": low, "close": close, "volume": volume})
                dfvol = pd.DataFrame({"date": date, "open": open, "high": high, "low": low, "close": volume, "volume": volume})

                df["sma10"] = SMA(df, 10)
                df["sma30"] = SMA(df, 30)
                df["sma50"] = SMA(df, 50)
                df["sma200"] = SMA(df, 200)
                df["rsi"] = RSI(df)
                df["williams"] = WILLIAMS(df)
                df["adx"] = ADX(df)
                df["bbwidth"] = BBWIDTH(df)
                df["vol10"] = SMA(dfvol, 10)
                df["vol30"] = SMA(dfvol, 30)

                LIST = [
                    float(df.tail(1)['sma10']), 
                    float(df.tail(1)['sma30']), 
                    float(df.tail(1)['sma50']), 
                    float(df.tail(1)['sma200']), 
                    float(df.tail(1)['rsi']),
                    float(df.tail(1)['williams']), 
                    float(df.tail(1)['adx']), 
                    float(df.tail(1)['bbwidth']),
                    float(df.tail(1)['vol10']),
                    float(df.tail(1)['vol30']),
                    float(df.tail(1)['close']),
                    yearPer,
                    monthPer,
                    fiveDayPer
                ]

                q = 0; NEW = []
                for K in LIST:
                    if math.isnan(K) == True:
                        NEW.append(0)
                    else:
                        NEW.append(K)
                    q += 1

                NEW.append(k[j])
                LIST.append(k[j])


                all_data.append( 
                    tuple( 
                    NEW
                    )
                    )

            except:
                pass
                

        j += 1  # going to the next ticker
    
    # this controls the amount of requests per second
    end = time.time()
    while end-start < 1.01:
        end = time.time()

print("total time to get data and make calculations: ",time.time() - Start_time)
print()

var = ['sma10','sma30','sma50','sma200','rsi','williams','adx','bbwidth','avgVol10day','avgVol30day','price','yearPer','monthPer','fiveDayPer'] # variable that we are updating
 
# table to insert into
table = 'stockStats_dev'
sql = UpdateBulk(var, table, 'ticker')

# # inserting the data into the table
mycursor.executemany(sql, all_data)

# closing access to the database
mydb.commit()
mycursor.close()
mydb.close()

这是完整的错误消息

Answer 1

# table to insert into
table = 'stockStats_dev'
sql = UpdateBulk(var, table, 'ticker')

# ADD THIS
del all_data['inf']

# inserting the data into the table
mycursor.executemany(sql, all_data)

# closing access to the database
mydb.commit()
mycursor.close()
mydb.close()
