請參閱下面的DDL:Commiting外部事務
create table dbo.Test (id INT)
create PROCEDURE TestProcedure1
as
begin
exec TestProcedure2
insert into Test values (2)
end
create PROCEDURE TestProcedure2
as
begin
begin transaction
insert into Test values (2)
end
現在運行此:
exec TestProcedure1 commit
錯誤輸出低於:
(1 row(s) affected)
Msg 266, Level 16, State 2, Procedure TestProcedure2, Line 0
Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1.
(1 row(s) affected)
Msg 266, Level 16, State 2, Procedure TestProcedure1, Line 0
Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1.
我理解錯誤的原因即TestProcedure2中沒有結束事務。這有什麼影響?我看到的錯誤後,我跑到下面的SQL語句:
select * from dbo.Test
這回兩行即外部事務提交的內部事務。我有兩個問題:
1) Does the outer transaction always commit the inner transaction.
2) After executing the select statement I executed the following commands:
commit
commit
What affect does running two commit statements have in this scenario?
