Question

我有一个运行3个查询的函数并返回最后一个的结果（使用前面的那些创建最后一个）当我到达第3个查询时，它得到一个列表索引我们的范围错误。我已经运行了这个确切的查询作为第一个查询（手动输入变量），它运行正常。

这是我的代码：

import pypyodbc

def sql_conn():
    conn = pypyodbc.connect(r'Driver={SQL Server};'
                            r'Server=HPSQL31\ni1;'
                            r'Database=tq_hp_prod;'
                            r'Trusted_Connection=yes;')
    cursor = conn.cursor()

    return conn, cursor


def get_number_of_jobs(ticket):
    # Get Connection
    conn, cursor = sql_conn()

    # Get asset number
    sqlcommand = "select top 1 item from deltickitem where dticket = {} and cat_code = 'Trq sub'".format(ticket)

    cursor.execute(sqlcommand)

    asset = cursor.fetchone()[0]

    print(asset)
    # Get last MPI date
    sqlcommand = "select last_test from prevent where item = {} and description like '%mpi'".format(asset)

    cursor.execute(sqlcommand)

    last_recal = cursor.fetchone()[0]

    print(last_recal)

    # Get number of jobs since last recalibration
    sqlcommand = """select count(i.item)
                    from deltickhdr as d
                    join deltickitem as i
                    on d.dticket = i.dticket
                    where i.start_rent >= '2017-03-03 00:00:00'
                    and i.meterstart <> i.meterstop
                    and i.item = '002600395'""" #.format(last_recal, asset)

    cursor.execute(sqlcommand)

    num_jobs = cursor.fetchone()[0]
    print(num_jobs)

    cursor.close()
    conn.close()

    return num_jobs

ticketnumber = 14195 # int(input("Ticket: "))
get_number_of_jobs(ticketnumber)

以下是我到达第3个cursor.execute（sqlcommand）时得到的错误

IndexError: list index out of range

任何帮助都会很棒

Answer 1

我有同样的错误。即使我还没有就这个错误意味着什么得出明确的结论，我仍认为我的猜测可能会帮助到此为止的其他任何人。

在我的情况下，问题是与数据类型长度（NVARCHAR（24）和CHAR（10））冲突。

所以我猜测 IndexError函数中的这个ctrl_err只是意味着您的SQL代码有一个错误，pypyodbc不知道如何处理。 / p>

我知道这并不是一个完整的答案，但是我知道，如果我不知道这不是pypyodbc中的错误，而是我插入的数据不一致，那就可以节省几个小时。 / p>

亲切的问候，卢卡

pypyodbc execute返回列表索引超出范围错误
