pyodbc insert decimal Error converting data type nvarchar to float

Question

看不懂，是哪个问题导致的：

将数据类型 nvarchar 转换为 float 时出错。

我正在通过 api 从一个软件获取数据，并想将这些数据插入到 sql 数据库中。 我在探查器中看到的……并怀疑，十进制或整数的问题

我试过替换，但后来我得到了相同的结果和

VALUES(?,?,convert(int,replace(?,',','.')),?,?, convert(decimal(18,2),replace(?,',','.')),?,?,?,?,?) END"

将数据类型 nvarchar 转换为数字时出错。

for t in tuples:
    print(t)
    use = t[0]
    btiId = t[1]
    area = None
    if t[2] is not None:
        area = round(float(str(t[2])[:str(t[2]).find('.')+2]),2)
    else:
        area = None
    print(area)
    number = t[5]
    name = t[3]
    building = None
    floor = None
    premise = None
    if t[8] is not None:
        building = t[8][0]['name']
    else:
        bulding = None
    if t[9] is not None:
        floor = t[9][0]['name']
    else:
        floor = None
    t = (btiId, building, floor, number, premise, name, area, area, area, 'BPS', 'Коммерческие', 'БПС',use, btiId,area,btiId)
    print(t)
