Question

我只想执行一次存储过程，但每次都从临时表#tbl_schools传递不同的参数值。我怎样才能完成这项任务？

create table #tbl_schools(id int not null)

insert into #tbl_schools(id) values (1)
insert into #tbl_schools(id) values (2)
insert into #tbl_schools(id) values (3)
insert into #tbl_schools(id) values (4)
insert into #tbl_schools(id) values (5)
insert into #tbl_schools(id) values (6)
insert into #tbl_schools(id) values (7)

select * from #tbl_schools nolock

go-----------

create proc sp_Prac @id int
as
print 'ID is: ' + cast(@id as varchar(10)) + char(10)

go-----------

exec sp_Prac @id = select id from #tbl_schools  -- This part errors out.

试试这个答案：

CREATE TABLE #tbl_schools(id INT NOT NULL)

INSERT INTO #tbl_schools(id) VALUES (5)
INSERT INTO #tbl_schools(id) VALUES (13)
INSERT INTO #tbl_schools(id) VALUES (1)
INSERT INTO #tbl_schools(id) VALUES (7)
INSERT INTO #tbl_schools(id) VALUES (2)
INSERT INTO #tbl_schools(id) VALUES (8)
INSERT INTO #tbl_schools(id) VALUES (4)

SELECT * FROM #tbl_schools NOLOCK

GO-----------

CREATE PROC sp_Prac @id INT
AS
PRINT 'ID is: ' + CAST(@ID AS VARCHAR(10)) + CHAR(10)

GO-----------

DECLARE @MAX INT, @MIN INT, @CurValue INT
SELECT *,ROW_NUMBER() OVER(ORDER BY id)RN
INTO #MyTable
FROM #tbl_schools
SELECT @MAX=MAX(RN),@MIN=MIN(RN) FROM #MyTable

WHILE @MIN<=@MAX
BEGIN
SELECT @CurValue=ID FROM #MyTable WHERE RN=@MIN
EXEC sp_Prac @id = @CurValue
SET @MIN=@MIN+1
END

DROP TABLE #tbl_schools
DROP TABLE #MyTable

<强>结果：

ID is: 1

ID is: 2

ID is: 4

ID is: 5

ID is: 7

ID is: 8

ID is: 13

仅执行一次存储过程，但传递不同的参数值10次
