sqlserver事务处理的代码

begin try
begin transaction
insert into shiwu (asd) values ('aasdasda');
commit transaction
end try
begin catch
select ERROR_NUMBER() as errornumber
rollback transaction
end catch
 

set implicit_transactions on; -- 启动隐式事务
go
begin try
insert into shiwu (asd) values ('aasdasda');
insert into shiwu (asd) values ('aasdasda');
commit transaction;
end try
begin catch
select ERROR_NUMBER() as errornumber
rollback transaction; --回滚事务
end catch
set implicit_transactions off; --关闭隐式事务
go
 

alter database;
backup;
create database;
drop database;
reconfigure;
restore;
update statistics;
 

--创建存储过程
create procedure qiantaoProc
@asd nchar(10)
as
begin
begin try
begin transaction innerTrans
save transaction savepoint --创建事务保存点
insert into shiwu (asd) values (@asd);
commit transaction innerTrans
end try
begin catch
rollback transaction savepoint --回滚到保存点
commit transaction innerTrans
end catch
end
go
begin transaction outrans
exec qiantaoProc 'asdasd';
rollback transaction outrans

事务嵌套，回滚外层事务时，如果嵌套内的事务已经回滚过则会有异常。
此时便需要使用事务保存点，如上代码所示。
