python中的sqlite3连接器

Question

这不管用：我没有任何元素。你知道吗

k0是float numpy，dk是int：

(k0, dk)
(<class 'numpy.float64'>, <class 'int'>)
(20.083143869749225, 6)

-

get_close_rods = "select xmid, ymid, angle from datos where  experiment_id=? "
get_close_rods+= "and file_id=? and ymid between ? and ? and xmid between ? and ? and angle between ? and ? "
get_close_rods+= "and major/minor between ? and ? order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle" 
#get_close_rods+= "order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle"

args = (str(experiment_id_), str(file_ids[index+1]), str(pos0[1]-dd),
            str(pos0[1]+dd), str(pos0[0]-dd), str(pos0[0]+dd),
            str(angle-dangle), str(angle+dangle), str(k0-dk), str(k0+dk),
            str(pos0[0]), str(pos0[0]), str(pos0[1]), str(pos0[1]))

cursor2.execute(get_close_rods, args)

str（k0-dk），str（k0+dk）

它也不起作用：

get_close_rods = "select xmid, ymid, angle, from datos where  experiment_id=? "
get_close_rods+= "and file_id=? and ymid between ? and ? and xmid between ? and ? and angle between ? and ? "
get_close_rods+= "and major/minor between ? and ? order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle" 
#get_close_rods+= "order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle"

args = (str(experiment_id_), str(file_ids[index+1]), str(pos0[1]-dd),
            str(pos0[1]+dd), str(pos0[0]-dd), str(pos0[0]+dd),
            str(angle-dangle), str(angle+dangle), str(15), str(25),
            str(pos0[0]), str(pos0[0]), str(pos0[1]), str(pos0[1]))

cursor2.execute(get_close_rods, args)

str（15），str（25）

如果我把str（float（15）），str（float（25））放进去也不起作用。你知道吗

当我使用那个查询时，它没有显示任何错误。你知道吗

但这是可行的：

get_close_rods = "select xmid, ymid, angle, from datos where  experiment_id=? "
get_close_rods+= "and file_id=? and ymid between ? and ? and xmid between ? and ? and angle between ? and ? "
#get_close_rods+= "and major/minor between ? and ? order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle" 
#get_close_rods+= "order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle"
get_close_rods+= "and major/minor between 15 and 25 order by ((xmid-?)*(xmid-?)+(ymid-?)*(ymid-?))*angle"

args = (str(experiment_id_), str(file_ids[index+1]), str(pos0[1]-dd),
            str(pos0[1]+dd), str(pos0[0]-dd), str(pos0[0]+dd),
            str(angle-dangle), str(angle+dangle), #str(15), str(25),
            str(pos0[0]), str(pos0[0]), str(pos0[1]), str(pos0[1]))

cursor2.execute(get_close_rods, args) 

#str（15），str（25）

Answer 1

使用直接值修复它：

args = (..., 15, 25, ...)

或：

args = (..., k0-dk, k0+dk, ...)
