I have a table containing a student-grade relationship:
Student Grade StartDate EndDate
1 1 09/01/2009 NULL
2 2 09/01/2010
I prefer the following, it is cleaner and easier to read and modify.
MERGE Definition.tdSection AS Target
USING
(SELECT *
FROM ( VALUES
( 1, 1, 'Administrator', 1, GETDATE(), NULL, Current_User, GETDATE())
,( 2, 1, 'Admissions', 1, GETDATE(), NULL, Current_User, GETDATE())
,( 3, 1, 'BOM', 1, GETDATE(), NULL, Current_User, GETDATE())
,( 4, 1, 'CRC', 1, GETDATE(), NULL, Current_User, GETDATE())
,( 5, 1, 'ICM', 1, GETDATE(), NULL, Current_User, GETDATE())
,( 6, 1, 'System', 1, GETDATE(), NULL,Current_User, GETDATE())
,( 7, 1, 'Therapy', 1, GETDATE(), NULL, Current_User, GETDATE())
)
AS s (SectionId
,BusinessProcessId
,Description, Sequence
,EffectiveStartDate
,EffectiveEndDate
,ModifiedBy
,ModifiedDateTime)
) AS Source
ON Target.SectionId = Source.SectionId
WHEN NOT MATCHED THEN
INSERT (SectionId
,BusinessProcessId
,Description
,Sequence
,EffectiveStartDate
,EffectiveEndDate
,ModifiedBy
,ModifiedDateTime
)
VALUES (Source.SectionId
,Source.BusinessProcessId
,Source.Description
,Source.Sequence
,Source.EffectiveStartDate
,Source.EffectiveEndDate
,Source.ModifiedBy
,Source.ModifiedDateTime
);
