我需要编写一个只有执行语句的过程。
示例:
Create Procedure dbo.allSPExecute( @id int)
as
begin
EXEC dbo.tic @day= 7,@name = 'Gname',@Type = 'Utype'
EXEC dbo.tic @day= 7,@name = 'tname',@Type = 'Utype'
EXEC dbo.gtype @day = 7,@Tname = 'UName_By',@Udept = 'Dept'
End
我有50多个这样的陈述。我有一个表是Lookup:
ID Name SCol Dcol IOrd
1 dbo.tic Gname @name 1
1 dbo.tic tname @name 2
1 dbo.tic Utype @Type 1
1 dbo.tic Utype @Type 2
2 dbo.gtype UName_By @Tname 1
2 dbo.gtype Dept @Udept 1
有没有办法使得如果我传递ID,那么它将获取Lookup表中的值并执行该过程。有人可以帮忙吗?

最简单的解决方案 - 使您的存储过程如下:
Create Procedure dbo.allSPExecute( @id int)
as
DECLARE @SQL varchar(max)
SET @SQL = 'USE MyDB'
SELECT @SQL = @SQL +
'EXEC ' + t.Name + ' @day = 7,' + t.Dcol + ' = ''' + t.Scol + ''
FROM MyTable t
WHERE t.id = @ID
EXEC (@SQL)

这是一个不需要游标的解决方案。我使用FOR XML关键字将字符串连接在一起。我在两个地方这样做 - 一次用于连接参数列表,一次用于连接所有单独的exec语句。我没有测试过这个,但我认为这应该比使用游标快得多
CREATE PROCEDURE dbo.allSPExecute( @id INT )
AS
BEGIN
DECLARE @query VARCHAR(MAX);
SELECT @query = (
SELECT ExecPart + ' ' + SUBSTRING(Params,2,LEN(Params)) + CHAR(10)
FROM
(
SELECT
ExecPart ='EXEC ' +(SELECT TOP 1 Name FROM MyTable WHERE ID = @id) ,
Params = (SELECT ', ' + Dcol + ' = ' + Scol
FROM MyTable t1 WHERE ID = @id AND t1.IOrd = t.IOrd FOR XML PATH(''))
FROM MyTable t
WHERE ID = @id
GROUP BY IOrd
) t
FOR XML PATH('')
)
EXEC (@query)
END

这是一个从头开始编写并且未经测试的游标示例:
declare @dynsql as nvarchar(300)
declare @tname as nvarchar(100)
declare @tscol as nvarchar(100)
declare @tdcol as nvarchar(100)
set @dynsql = ''
declare ticker as cursor for select Name, SCol, DCol from Lookup
open ticker
fetch next from ticker into @tname, @tscol, @tdcol
while @@FETCH_STATUS = 0
BEGIN
set @dynsql = 'EXEC ' + @tname + ' @day=7, ' + @tdcol + '=''' + @tscol + ''''
exec(@dynsql)
FETCH NEXT from ticker into @tname, @tscol, @tdcol
END
close ticker
deallocate ticker
