用户定义的数据类型要放在使用他的数据库里才有效,由于存储过程中建立的临时表会建立在tempdb里面,所以要先在tempdb里执行,再在mastrer里执行
查看用户定义的数据类型:

sql2005: select * from sys.types where is_user_defined=1
sql2000:select * from systypes where xtype<>xusertype

自定义数据类型
建立在SQL server系统数据类型基础上的，需要指定该类型的名称，建立在其上的系统数据类型及是否充许为空。
方法：利用系统存储过程：sp_addtype
语法：sp_addtype type, [ system_data_type ] [ ,'nulltype' ]

1.计数方法

事务计数器从0开始，没嵌套一个事务，事务计数器+1，COMMIT一个事务计数器-1.
注意：事务保存点属于事务内部，不会对事务计数器产生影响。

下面的示例演示嵌套的 BEGIN 和 COMMIT 语句对 @@TRANCOUNT 变量产生的效果。
[code lang="sql"]
PRINT @@TRANCOUNT
-- The BEGIN TRAN statement will increment the
-- transaction count by 1.
BEGIN TRAN
PRINT @@TRANCOUNT
BEGIN TRAN
PRINT @@TRANCOUNT
-- The COMMIT statement will decrement the transaction count by 1.
COMMIT
PRINT @@TRANCOUNT
COMMIT
PRINT @@TRANCOUNT
--Results
--0
--1
--2
--1
--0
[/code]

2. 事务回滚对事务计数器的影响

当子事务ROLLBACK之后，会直接清零TRANCOUNT，下面的示例演示嵌套的 BEGIN TRAN 和 ROLLBACK 语句对 @@TRANCOUNT 变量产生的效果。
[code lang="sql"]
PRINT @@TRANCOUNT
-- The BEGIN TRAN statement will increment the
-- transaction count by 1.
BEGIN TRAN
PRINT @@TRANCOUNT
BEGIN TRAN
PRINT @@TRANCOUNT
-- The ROLLBACK statement will clear the @@TRANCOUNT variable
-- to 0 because all active transactions will be rolled back.
ROLLBACK
PRINT @@TRANCOUNT
--Results
--0
--1
--2
--0[/code]

3.使用保存点确保事务嵌套时能正确回滚

[code lang="sql"]
begin transaction trn_example

update tableName set fieldName = @value
save transaction stk_savePoint
update tableName2 set fieldName2 = @value2
if @@error<>0
begin
rollback transaction stk_savePoint
commit transaction
return
end
else
begin
if @@rowcount = 0
rollback transaction
end
commit transaction
--如果第二个update出现错误，就返回到第一个update后提交，并且使用return截断后面的语句继续运行
--如果第二个update正确执行，就是更新的行数是0，就回滚整个事务，把第一个update执行的结果也取消
[/code]
