SQLITE3从一个字段到另一个字段在同一个表和同一行中的数据传输

Question

我试图将数据从一个字段移动到另一个字段。 这是我的代码，但它不与更新语句的工作：

def update_ondemanddrama(Name): 
    with sqlite3.connect("sky_ondemand.db") as db: 
     cursor = db.cursor() 
     sql = "update TVshowsDrama set SecLastEp=LastEp where Name=?" 
     cursor.execute(sql, Name) 
     db.commit() 

工作

def insert_ondemanddrama(values): 
    with sqlite3.connect("sky_ondemand.db") as db: 
     cursor = db.cursor() 
     sql = "update TVshowsDrama set Name=?, LastEp=? where Name=?" 
     cursor.execute(sql,values) 
     db.commit() 

def insert_ondemanddoc(values): 
    with sqlite3.connect("sky_ondemand.db") as db: 
     cursor = db.cursor() 
     sql = "update TVshowsDoc set Name=?, LastEp=? where Name=?" 
     cursor.execute(sql,values) 
     db.commit() 


Type = int(input("Doc (1) or Drama (2)"))   
Name = input("Enter name of Show") 
LastEp = input("Enter Last episode aired (ex. s1e4)") 


if Type == 1: 
    if __name__== "__main__": 
     show = (Name, LastEp, Name) 
     insert_ondemanddoc(show) 
elif Type == 2: 
    if __name__== "__main__": 
     show = (Name, LastEp, Name) 
     update_ondemanddrama(Name) 
     insert_ondemanddrama(show) 
elif Type >=3: 
    print ("Incorrect entry") 

的错误我得到蟒蛇运行是这样的：

Traceback (most recent call last): File "C:\Users\ict\Downloads\skyondemandv1.py", line 65, in <module> 
update_ondemanddrama(Name) File "C:\Users\ict\Downloads\skyondemandv1.py", line 34, in 
update_ondemanddrama cursor.execute(sql, Name) sqlite3.ProgrammingError: Incorrect number of bindings supplied. 
The current statement uses 1, and there are 5 supplied.

光标.execute期望一个迭代。当你给它一个字符串时，执行将它看作是一个可迭代的5个项目（5个字符）。 将执行行更改为

cursor.execute(sql, (Name,))
