Question

我正在尝试运行此代码但是我收到以下错误... 实际上，我正在尝试使用OpenCV进行人脸识别..

import sqlite3
import cv2
import numpy as np
import urllib.request as ur
faceDetect=cv2.CascadeClassifier('haarcascade_frontalface_default.xml')

def insert(ID,Name):
    conn=sqlite3.connect("FaceBase.db")
    cmd="SELECT * FROM People Where id=?"+str(id)
    cursor=conn.execute(cmd)
    doesRecordExist=0
    for row in cursor:
        doesRecordExist=1
    if(doesRecordExist==1):
        cmd="UPDATE People SET Name="+str(Name)+"WHERE Id="+str(ID)
    else:
        cmd="INSERT INTO People(ID,Name) Values("+str(ID)+","+str(Name)+")"
    conn.execute(cmd)
    conn.commit()
    conn.close()

但我得到了这个错误：

  File "C:/Users/Sandesh R Patil/Desktop/Project/Face Recog 
sqlite/datasetCreator.py", line 10, in insert
    cursor=conn.execute(cmd)

OperationalError: near "in": syntax error

第9行的ID不正确请尝试：

import sqlite3
import cv2
import numpy as np
import urllib.request as ur
faceDetect=cv2.CascadeClassifier('haarcascade_frontalface_default.xml')

def insert(ID,Name):
    conn=sqlite3.connect("FaceBase.db")
    cmd="SELECT * FROM People WHERE id=?"+str(ID)
    cursor=conn.execute(cmd)
    doesRecordExist=0
    for row in cursor:
        doesRecordExist=1
    if(doesRecordExist==1):
        cmd="UPDATE People SET Name="+str(Name)+" WHERE Id="+str(ID)
    else:
        cmd="INSERT INTO People(ID,Name) Values("+str(ID)+","+str(Name)+")"
    conn.execute(cmd)
    conn.commit()
    conn.close()
