如何解决 csv 文件导入中的字符串 [DT_STR] 错误

Question

我在 csv 文件中从 Sybase DB 导出了一个表及其数据。然后我打算使用 SSMS 18 将它导入到 MSSQL Server 中。

我在 MSSQL Server 中创建了保留相同数据类型的表，如下所示：

CREATE TABLE [dbo].[employee_account](
    [UserID] [int] NOT NULL,
    [debit_acct_no] [varchar](20) NOT NULL,
    [active] [bit] NOT NULL,
    [create_dt] [datetime] NULL,
    [created_by] [varchar](45) NULL,
    [Limit] [numeric](26, 6) NOT NULL,
    [allow_od] [char](1) NOT NULL,
    [allow_bal_enq] [char](1) NULL,
    [scheme_type] [varchar](20) NULL
) ON [PRIMARY]
GO

然后我按照这个步骤：

右键单击数据库 -> 单击任务 -> 导入数据 -> 下一步 -> 选择平面文件作为数据源 -> 等等 ..

它在非字符串（Varchar、char）列上进行标记，并且从 CSV 文件导入失败。

样本数据：

UserID,debit_acct_no,active,create_dt,created_by,Limit,allow_od,allow_bal_enq,scheme_type
1,9876765432,1,20/03/2017 7:55:47.396,HAMIT LAMIL,13388.330000,N,,
1,2345654362,1,20/03/2017 7:56:01.120,HAMIT LAMIL,17715.330000,N,,
1,8797654324,1,20/03/2017 7:56:04.663,HAMIT LAMIL,88185.880000,N,,

我不想将所有其他列转换为 varchar。

即使我取消选中隐藏，问题仍然存在。

当我完成这个过程时，我得到了这个错误：

Error 0xc02020c5: Data Flow Task 1: Data conversion failed while converting column "create_dt" (22) to column "create_dt" (88).  The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".

我该如何解决这个问题？
