Question

我正在尝试使用pymssql将数据插入SQL Server表。我的代码如下：

def main():
    out = get_sql()
    print("%s Batches to be exported" %(len(out)))
    with concurrent.futures.ProcessPoolExecutor(max_workers=4) as executor:
        for batch, i in enumerate(executor.map(scoring_and_loading, out)):
            try:
                conn = pymssql.connect(server="SQLDev02",database="DEVDB", user='', password='')
                curr = conn.cursor()
                query =  "INSERT INTO [dbo].[STG_CONTACTABILITY_SCORE] VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)"
                sql_data = list(map(tuple,i.values))
                curr.executemany(query, sql_data)
                conn.commit()
                print("Batch %s exported" %(batch))
            except Exception as e:
                print(e)

STG_CONTACTABILITY_SCORE定义如下：

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[STG_CONTACTABILITY_SCORE](
    [RecordType] [varchar](30) NULL,
    [ContactName] [varchar](100) NULL,
    [AccountName] [varchar](100) NULL,
    [ContactabilityScore] [int] NULL,
    [PreferredPhoneNumber] [varchar](15) NULL,
    [PreferredCallerId] [varchar](15) NULL,
    [DoubleDialRecommended] [varchar](1) NULL,
    [DayofTheWeek] [varchar](15) NULL,
    [CallBlockStartTime] [varchar](15) NULL,
    [CallBlockEndTime] [varchar](15) NULL,
    [Season] [varchar](15) NULL,
    [CallDuration] [varchar](15) NULL,
    [DialNumber] [varchar](20) NULL,
    [Cumulative#ofAttempts] [int] NULL,
    [LastUpdatedDate] [date] NULL,
    [LoadDate] [date] NULL,
    [LoadStatus] [varchar](30) NULL,
    [LoadNumber] [int] NULL,
    [ContactId] [varchar](50) NULL,
    [TimeZone] [varchar](200) NULL,
    [BatchNumber] [varchar](50) NULL,
    [AccountId] [varchar](20) NULL
) ON [PRIMARY]

GO

有关我试图插入表中的数据框的信息如下：

<class 'pandas.core.frame.DataFrame'>
Int64Index: 9800 entries, 0 to 9799
Data columns (total 22 columns):
RecordType               9800 non-null object
ContactName              9800 non-null object
AccountName              9800 non-null object
ContactabilityScore      9800 non-null float64
PreferredPhoneNumber     9800 non-null object
PreferredCallerId        0 non-null object
DoubleDialRecommended    0 non-null object
DayofTheWeek             9800 non-null object
CallBlockStartTime       9800 non-null object
CallBlockEndTime         9800 non-null object
Season                   9800 non-null object
CallDuration             0 non-null object
DialNumber               0 non-null object

LastUpdatedDate          9800 non-null object
LoadDate                 9800 non-null object
LoadStatus               9800 non-null object
LoadNumber               0 non-null object
ContactId                9800 non-null object
TimeZone                 9800 non-null object
BatchNumber              0 non-null object
AccountId                9800 non-null object
dtypes: float64(1), object(21)

我检查了AccountName或ContactName中是否有任何长度大于100并且未找到任何值的值。我无法理解我做错了什么。我将非常感谢你的帮助。非常感谢。
