使用存儲過程來插入從選擇

Question

我需要使用存儲過程，它看起來像這樣將數據插入到另一個表中的數據：

CREATE PROCEDURE T.countnum 
AS 
    Insert into T1 values(select count(*) from T.countTable) 

但它不工作，我看見幾個例子，但不與選擇。任何示例？

Answer 1

use db; 
CREATE PROCEDURE T.countnum 
AS 
Insert into T1 ([column_name]) 
select count(*) 
from T.countTable 
go 

或

use db; 
CREATE PROCEDURE T.countnum 
AS 

declare @counting int 

select @counting = count(*) 
from T.countTable 

Insert into T1 ([column_name]) values (@counting) 

go 

你應該指定列數一樣 select count(id) from T.countTable

Answer 2

你可以嘗試：

Insert into T1(CountColumn) 
select count(*) from T.countTable 

Answer 3

這是語法：

INSERT INTO MyTable 
( 
    Column1, 
    Column2 
) 
EXEC [dbo].[yourStoredProcName] 

Answer 4

use db; 
CREATE PROCEDURE T.countnum 
AS 
Insert into T1 values((select count(*) from T.countTable)) 
go
