Sqlserver表值类型和表变量

Sqlserver表类型和表变量

表类型可以用在存储过程中，用于批量增加

sqlserver2008表类型定义：
[sql]

use Customer

GO

if exists(select 1 from systypes where name='Type_TB_Biz_Account')

    drop typeType_TB_Biz_Account

GO

----------------------------------------------------------

-- TypeName: Type_TB_Biz_Account 

----------------------------------------------------------

CREATE TYPE Type_TB_Biz_Account  AS TABLE

(

    Account int,

    Balance decimal(19,2),

    Credit decimal(19,2),

    [Readonly] int

);

GO

if exists(select 1 from sysobjects where name='SP_Biz_Account_BatchUpdateBalance')

    drop proc SP_Biz_Account_BatchUpdateBalance

GO

----------------------------------------------------------

-- ProcedureName: 批量更新账户余额、信用额

----------------------------------------------------------

create proc SP_Biz_Account_BatchUpdateBalance

@TBAccount  Type_TB_Biz_Account  readonly

as

    update TB_Biz_Account

    set Balance=New.Balance,Credit=New.Credit

    FROM dbo.TB_Biz_Account as Cur 

    INNER JOIN @TBAccount AS New  ON Cur.Account = New.Account;

   

    return @@rowcount

GO

sqlserver2005好像不支持表类型，不过支持表变量
表变量定义： 
[sql]

declare  @mtTable  table(

    id int,

    [name]varchar(10)

)
