大家好，我想将Excel数据导入sql表。上图中给出了样本数据。我需要将日期，代码，员工列数据的数据插入各自的类型列。

您能帮我解决ssis任务吗？就像我需要取消对前3列的分组。

Answer 1

这是您解决该问题的方法：

1。像这样在数据库中创建登台表。请记住，插入时需要具有“身份”列：

CREATE TABLE tbl_Excel_stg (
    ID INT IDENTITY(1,1),
    [Date] VARCHAR(50),
    code VARCHAR(50),
    Employee VARCHAR(50),
    [type] VARCHAR(50),
    total VARCHAR(50),
    actual VARCHAR(50)
)

2。构建SSIS包以将Excel数据加载到登台表中。

3。运行以下查询以提取更正的数据（为了测试目的，我已经包含了一些数据）

INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('2018-12-12','Itsdysa','3026262','general','150','139');
GO
INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('','','','typica','200','177');
GO
INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('','','','dummy','120','100');
GO
INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('2018-12-14','hskdbegs','3630878','new','300','143');
GO
INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('','','','typical','100','99');
GO
INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('','','4829264','dummy','210','187');
GO
INSERT INTO tbl_Excel_stg ([Date],code,Employee,type,total,actual)
VALUES ('','','','general','130','89');
GO

SELECT [Date] = CASE s0.[Date] WHEN '' THEN s1.[Date] ELSE s0.[Date] END
    , code = CASE s0.code WHEN '' THEN s1.code ELSE s0.code END
    , Employee = CASE s0.Employee WHEN '' THEN s1.Employee ELSE s0.Employee END
    , s0.type, s0.total, s0.actual
FROM tbl_Excel_stg as s0
OUTER APPLY (
    SELECT ID = MAX(si.ID) FROM tbl_Excel_stg as si
    WHERE si.ID < s0.ID and si.[Date] != ''
) as sDate
OUTER APPLY (
    SELECT ID = MAX(si.ID) FROM tbl_Excel_stg as si
    WHERE si.ID < s0.ID and si.code != ''
) as scode
OUTER APPLY (
    SELECT ID = MAX(si.ID) FROM tbl_Excel_stg as si
    WHERE si.ID < s0.ID and si.Employee != ''
) as sEmployee
LEFT JOIN tbl_Excel_stg as s1 ON s1.ID = sDate.ID
LEFT JOIN tbl_Excel_stg as s2 ON s2.ID = scode.ID
LEFT JOIN tbl_Excel_stg as s3 ON s3.ID = sEmployee.ID
ORDER BY s0.ID

解决方案可能不是很漂亮，但是很容易理解/更改/调试

Answer 2

在SSIS中，您可以使用脚本组件来实现：

添加DataFlow任务
在“数据流任务”中，添加Excel源，脚本组件和OLEDB目标
在脚本组件中，添加3个新的输出列（outdate，outcode和outemployee），它们的数据类型与源列相同。
在“脚本”组件中，选择Visual Basic作为脚本语言

在脚本编辑器中，编写以下代码：

Private Lastdate as string
Private LastEmployee as string
Private Lastcode as string

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)

If Not Row.date_IsNull Then

    Row.outdate = Row.date
    Lastdate = Row.date
Else

    Row.outdate = Lastdate

End If

If Not Row.employee_IsNull Then

    Row.outemployee = Row.employee
    Lastemployee = Row.employee
Else

    Row.outemployee = Lastemployee

End If

If Not Row.code_IsNull Then

    Row.outcode = Row.code
    Lastcode = Row.code
Else

    Row.outcode = Lastcode

End If




End Sub

将新创建的列以及type，total和actual列映射到相关的目标列
