Question

我正在使用sql server 2012 我的桌子像

表：订单

|idOrder| idCustomer | dateTransaction| invoice |
| 1001  | 104        | 2014-06-09     |         |

idOrder使用自动增量，我想询问如何获取刚插入的id命令并与date transaction结合，我的SP for insertOrder：

BEGIN
INSERT INTO Order
(
 idCustomer,
 transactionDate,
 invoice
)
VALUES
(
 @idCustomer,
 GETDATE(),
 CAST(datepart(year, getdate()) AS VARCHAR(10)) + CAST(datepart(month, getdate()) AS VARCHAR(10)) + CAST(@idCustomer AS VARCHAR(10))
)
END

到目前为止，我得到了

|idOrder| idCustomer | dateTransaction| invoice     |
| 1001  | 104        | 2014-06-09     |  201406104  |

我想要的是

|idOrder| idCustomer | dateTransaction| invoice     |
| 1001  | 104        | 2014-06-09     |  2014061001 | --> 1001 is idOrder

如何在插入新数据时同时将idOrder（自动增量）转入发票字段/或

exec SP插入后exec SP更新如何获取idOrder，因为IdOrder是自动增量所以它没有参数

感谢

完整的代码有效！

BEGIN
INSERT INTO Order
(
 idCustomer,
 transactionDate,
 invoice
)
VALUES
(
 @idCustomer,
 GETDATE(),
 CAST(datepart(year, getdate()) AS VARCHAR(10)) + CAST(datepart(month, getdate()) AS VARCHAR(10)) + CAST(@idCustomer AS VARCHAR(10))
)
END

DECLARE @ID INT SELECT @ID = SCOPE_IDENTITY（）更新TR_Order SET Invoice = CAST（Invoice AS VARCHAR）+ CAST（@ID AS VARCHAR） WHERE IdOrder = @ID

Answer 1

首先插入记录并使用

获取插入的ID

SCOPE_IDENTITY()
OR
@@IDENTITY

DECLARE @ID INT
SELECT @ID =  SCOPE_IDENTITY()
UPDATE TABLE_Name
SET Invoice = CAST(Invoice AS VARCHAR) +  CAST(@ID AS VARCHAR)
WHERE IdOrder = @ID

然后再次更新表格，因为在插入记录之前无法获取ID。

Answer 2

插入您的记录
获取ID
执行对该记录的更新

假设我们有这张桌子

CREATE TABLE my_table (id INT IDENTITY(1,1), col1 VARCHAR(32));

现在这是您的代码


DECLARE @id INT;

 -- here is your insert statement (1)
INSERT INTO my_table (col1) VALUES('000');

-- get the id (2)
SET @id = scope_identity(); 

-- perform update to that record
UPDATE my_table     
SET col1=col1 + CAST(@id AS VARCHAR)
WHERE id=@id;

Demo

插入新值时，使用相同id的数字插入另一个字段
