Question

我有这个sql语句，我想转换为存储过程。我怎样才能做到这一点？

select a.name, a.lastname, from myTable where b.name= a.lastname

由于

UPDATE 这会是对的吗

CREATE PROCEDURE myProcedure
AS
BEGIN
SELECT [a.name],
       [a.lastname]
FROM [myTable]
WHERE [b.name] = a.lastname
END

这是我正在努力的代码之一

sql语句

SELECT RTRIM(l.Lab1) + '/' + RTRIM(l.LabR) AS Lab, meta.Title,ls.[ID],ls.[surveyID], ls.[specialistID],ls.[isCompleted] FROM [MyDIM].[dbo].[lsLabSurvey] ls JOIN [MYDIM].[dbo].[dimDocMetaInfo] meta ON meta.id = ls.[surveyID] and specialistID = @PID and isCompleted=1 JOIN MyDatabase.DBO.PID_Table l ON ls.ID = l.ID

我的尝试存储过程

CREATE PROCEDURE PROCD1
AS
BEGIN
SELECT RTRIM(l.Lab1) + '/' + RTRIM(l.LabR) 
AS Lab, 
   meta.Title,
   la.[ID],
   ls.[surveyID],
   ls.[specialistID],
   ls.[isCompleted]
FROM [MyDIM].[dbo].[lsLabSurvey] ls 
JOIN [MyDIM].[dbo].[dimDocMetaInfo] meta 
ON meta.id = ls.[surveyID] 
and specialistID = @PID 
and isCompleted=1 
JOIN MyDatabase.DBO.PID_Table l 
ON ls.ID = l.ID

END

真的不是那么难。你有95％的路在那里。以下内容适用于SQL Server：

CREATE PROCEDURE SomeProcedureName  
AS  
select a.name, a.lastname, from myTable where b.name= a.lastname

我强烈推荐这本书：http://www.barnesandnoble.com/w/sams-teach-yourself-sql-in-10-minutes-ben-forta/1100070678

它涵盖了基本的SQL语法，并提供了SQL的不同“方言”的示例。每个RDBMS执行类似功能的语法略有不同，您需要知道您正在使用的DB的方言。

正如大卫所说，你几乎在那里但只是需要做些小改动。

我认为@Pid是一个参数，如果是，则存储过程定义中缺少它。
（和specialistId = @ Pid和iscompleted = 1）形成Where子句（Filter表达式）。所以程序就像这样

`

CREATE PROCEDURE PROCD1 (@PID INT )
AS 
    BEGIN
        SELECT  CONVERT(VARCHAR,RTRIM(l.Lab1)) + '/' + CONVERT(VARCHAR,RTRIM(l.LabR)) AS Lab ,
                meta.Title ,
                la.[ID] ,
                ls.[surveyID] ,
                ls.[specialistID] ,
                ls.[isCompleted]
        FROM    [MyDIM].[dbo].[lsLabSurvey] ls
                INNER JOIN [MyDIM].[dbo].[dimDocMetaInfo] meta ON meta.id = ls.[surveyID]
                INNER JOIN MyDatabase.DBO.PID_Table l ON ls.ID = l.ID
        WHERE   ls.specialistID = @PID
                AND ls.isCompleted = 1
    END 
`

希望这有帮助。
