我正在尝试使用 python tkinter sqlite3 创建一个注册表单，但是我有一个问题，当我只更新一条记录时，所有名称都会更新（不仅仅是选择的那个），我也有这个当我尝试添加新数据时出现问题：c.execute("INSERT INTO SCHOOL VALUES (:ID, :NAME, :BIRTH, :DOCS, :FATHER, :MOTHER, :CLASS)", sqlite3.IntegrityError: UNIQUE constraint failed: SCHOOL.CLASS，并且我不能添加超过 2 条记录。
我想要一些帮助来解决这个问题，这是代码：
from tkinter import *
from tkinter import ttk
import _sqlite3
root = Tk()
root.title('trying again')
root.geometry("1000x500")
data = [["1", "BOB", "27/10/2020", "234512", "JOHN", "DOE", "6º"],
]
# conectar a database
conn = _sqlite3.connect('tree_crm.db')
c = conn.cursor()
c.execute("""CREATE TABLE IF NOT EXISTS SCHOOL (
ID text,
NAME txt,
BIRTH txt,
DOCS txt,
FATHER txt,
MOTHER txt,
CLASS txt
oid PRIMARY KEY)
""")
# aDD RECORD TO TABLE
for record in data:
c.execute("INSERT OR IGNORE INTO SCHOOL VALUES (:ID, :NAME, :BIRTH, :DOCS, :FATHER, :MOTHER, :CLASS)",
{
'ID': str(record[0]),
'NAME': str(record[1]),
'BIRTH': str(record[2]),
'DOCS': str(record[3]),
'FATHER': str(record[4]),

}
)
conn.commit()
conn.close()
def query_database():

c = conn.cursor()
c.execute("SELECT oid, * FROM SCHOOL")
records = c.fetchall()
global count
count = 0
for record in records:
if count % 2 == 0:
my_tree.insert(parent='', index='end', iid=count, text='',
values=(
record[1], record[2], record[3], record[4], record[5], record[6], record[7], record[0]),
