pyodbc.ProgrammingError: ('The SQL contains 1 parameter markers, but 7 parameters were supplied', 'HY000')

Question

当运行下面的脚本以以下错误结束时，因为我确实找到了关于此错误的其他帖子，所以我没有找到与我的脚本类似的修复方法。

language = ['Chinese (Simplified)', 'Chinese (Traditional)', 'English', 'French', 'Indonesian', 'Japanese', 'Korean']

cursor.execute("SELECT * from TABLE_NAME WHERE Language=?", language)
data = cursor.fetchall()

我遇到的错误：

pyodbc.ProgrammingError: ('The SQL contains 1 parameter markers, but 7 parameters were supplied', 'HY000')

Answer 1

inside language 有 7 项，但你只有 1 项？在 cursor.execute() 内你可以试试 lan=','.join([str(elem) for elem in language])

cursor.execute("SELECT * from TABLE_NAME WHERE Language in ?", 局域网)
