У мене є таблиця з нижньою структурою:
CREATE TABLE [dbo].[AUDIT_SCHEMA_VERSION](
[SCHEMA_VER_MAJOR] [int] NOT NULL,
[SCHEMA_VER_MINOR] [int] NOT NULL,
[SCHEMA_VER_SUB] [int] NOT NULL,
[SCHEMA_VER_DATE] [datetime] NOT NULL,
[SCHEMA_VER_REMARK] [varchar](250) NULL
);
деякі вибіркові дані (здається, проблема з sqlfiddle .. тому розміщення деяких зразкових даних):

Ось SQLFiddleз деякими зразками даних.
Чи може хтось, хто має досвід T-sql, орієнтувати мене на те, як досягти кінцевого результату? Я знаю, що PIVOT
(з динамічними колонками) буде правильним підходом, але не можу це зрозуміти.
Очікувані результати :
Поки що я маю нижче:
select row_number() over (
partition by CONVERT(varchar(10), SCHEMA_VER_DATE, 110) order by SCHEMA_VER_DATE
) as rownum
,CONVERT(varchar(10), SCHEMA_VER_DATE, 110) as UPG_DATE
,CONVERT(varchar(1), SCHEMA_VER_MAJOR) + '.' + CONVERT(varchar(2), SCHEMA_VER_MINOR) + '.' + CONVERT(varchar(2), SCHEMA_VER_SUB) as SCHEMA_VER
from audit_schema_version
where SCHEMA_VER_REMARK like 'Stored procedure build'
order by UPGRADE_DATE
