大家好，我想将excel数据导入到sql表中。样本数据如上图所示。 我需要根据各自的类型列插入日期、代码、员工列数据的数据。

预期输出

你能帮我完成 ssis 任务吗？ 就像我需要取消前 3 列的分组。

以下是解决该问题的方法:

1.像这样在数据库中创建临时表。请记住，插入时需要有“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 数据加载到临时表中。

3.运行以下查询以提取更正后的数据(我已包含一些用于测试目的的数据)

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，但易于理解/更改/调试
