在Microsoft SQL Server中，我用这句话创建了下表：

IF OBJECT_ID(N'dbo.STG_HICP', N'U') IS NOT NULL DROP TABLE dbo.STG_HICP;
CREATE TABLE dbo.STG_HICP(
    freq nvarchar(50)  not null,
unit nvarchar(100) not null,
    coicop varchar(50) not null,
    geo nvarchar(50) not null,
    period int not null,
    HICP numeric(12,2) null
)

一旦我在SQL中创建了这个表，我在Spoon中创建了一个像这样的转换：
第一步：
文本文件输入：
（预览数据）

第二步：
分割字段：

第三步：
表格输出：
当我运行将此tsv导入到SQL Server时，它不起作用，我得到以下消息：

我想这可能是由'period int not null'引起的，但我不知道如何解决它。
非常感谢您的帮助！
