You really should put in your question what you have tried so far, it helps out a lot and makes it more fun to help people.
The two ways I can think of in t-sql to solve this still need you to specify in your code what your column names are. You can get around this with using dynamic SQL and creating a view that spits out data in the same fashion for all the tables you need.
If SSIS is more your thing you could use the dynamic approach with BIML.
--Option 1 (SQL Server 2008 R2 and later)
with Table1 AS (
SELECT * FROM (values(1,'John'),(2,'Steve')) AS x(ID,NAME)
)
,Table2 AS (
SELECT * FROM (values(111,'USA','Done'),(222,'Brazil','Done'))AS y(No,Addrress,Notes)
)
SELECT '"Detail1"'+ CAST(foo as VARCHAR(4000))
FROM (
SELECT ';"' + CAST(ID AS VARCHAR(4))+'";"' + [NAME] +'"' FROM Table1 FOR XML PATH('')
) AS bar(foo)
UNION ALL
SELECT '"Detail2"'+ CAST(foo as VARCHAR(4000))
FROM (
SELECT ';"' + CAST([No] AS VARCHAR(4))+'";"' + [Addrress] +'";"' + [Notes] +'"' FROM Table2 FOR XML PATH('')
) AS bar(foo)
--Option 2 (SQL Server 2017 and later)
with Table1 AS (
SELECT * FROM (values(1,'John'),(2,'Steve')) AS x(ID,NAME)
)
,Table2 AS (
