内含游标的存储过程实例

第一种写法

GO
BEGIN
IF (object_id(\'PT_FAULT_REPORT\', \'P\') is not null) 
    drop proc PT_FAULT_REPORT;
END
GO
CREATE  PROCEDURE PT_FAULT_REPORT
(@index      int,
@stop_time        DATETIME,
@start_time       DATETIME)
AS
DECLARE
@departmentindex          int,
@departmentname   nvarchar(100),
@entitycount     int,
@allcount       int,
@fixtime         int,
@fixcount          int;
declare test_cur cursor for
   select field1, field2, field3, field4 form table where field1=@index and
         field2>@stop_time or filed3<@start_time  ;
OPEN test_cur; 
DECLARE @TableTemp TABLE(departmentindex  int,departmentname nvarchar(100),entitycount  int,allcount int,fixtime  int,fixcount  int);--定义表变量
   FETCH NEXT FROM test_cur INTO @departmentindex, @departmentname, @entitycount, @allcount, @fixtime,@fixcount;
   INsert @TableTemp values(@departmentindex, @departmentname, @entitycount, @allcount, @fixtime,@fixcount);--给表变量插值
WHILE @@FETCH_STATUS = 0
BEGIN
  FETCH NEXT FROM test_cur INTO @departmentindex, @departmentname, @entitycount, @allcount, @fixtime,@fixcount;
   INsert @TableTemp values(@departmentindex, @departmentname, @entitycount, @allcount, @fixtime,@fixcount);  

  --select departmentindex=@departmentindex, departmentname=@departmentname,entitycount=@entitycount, allcount=@allcount, fixtime=@fixtime,fixcount=@fixcount;
END ;
 CLOSe test_cur
 Deallocate test_cur;
 select * from @TableTemp;--存储过程返回数据

测试存储过程

GO  
DECLARE @starttime DATETIME,@endtime DATETIME;
set @starttime =GETDATE();
set @endtime=GETDATE()-30;
EXEC PT_FAULT_REPORT 3,@starttime,@endtime;

第二种传游标写法

 GO
BEGIN
IF (object_id(\'PT_FAULT_REPORT\', \'P\') is not null) 
    drop proc PT_FAULT_REPORT;
END
GO
CREATE  PROCEDURE PT_FAULT_REPORT
(@business_index  INTEGER , @start_time  DATETIME , @stop_time  DATETIME, @ds_cur  CURSOR VARYING OUTPUT)
AS
BEGIN
    SET @ds_cur = CURSOR  
    FORWARD_ONLY STATIC FOR  
 select field1, field2, field3, field4 form table where field1=@index and
         field2>@stop_time or filed3<@start_time  ;
OPEN @ds_cur 
END;

　　测试存储过程

GO  
DECLARE @MyCursor CURSOR,@starttime DATETIME,@endtime DATETIME;
set @starttime =GETDATE();
set @endtime=GETDATE()-30;
EXEC PT_FAULT_REPORT 3,@starttime,@endtime,@ds_cur = @MyCursor OUTPUT;  
FETCH NEXT FROM @MyCursor;  
WHILE (@@FETCH_STATUS = 0)  
BEGIN;  
     FETCH NEXT FROM @MyCursor;  
END;  
CLOSE @MyCursor;  
DEALLOCATE @MyCursor;

　　第三种写法(测试方法与第一种相似）

 GO
BEGIN
IF (object_id(\'PT_FAULT_REPORT\', \'P\') is not null) 
    drop proc PT_FAULT_REPORT;
END
GO
CREATE  PROCEDURE PT_FAULT_REPORT
(@business_index      int,
@stop_time        DATETIME,
@start_time       DATETIME)
AS
   select * from table
