How to call procedure for each row? - sql

Question

I have a Microsoft SQL Server R2 2008. And i see it first time in my life.
I have sql procedure:
DECLARE #RC int
DECLARE #Id uniqueidentifier
DECLARE #Segment_ID uniqueidentifier
DECLARE #SDate datetime
DECLARE #EDate datetime
DECLARE #withBig bit
DECLARE #withKm bit
DECLARE #withGeo bit
DECLARE #withDescr bit
-- TODO: задайте здесь значения параметров.
EXECUTE #RC = [Request_BusStation]
#Id
,#Segment_ID
,#SDate
,#EDate
,#withBig
,#withKm
,#withGeo
,#withDescr
GO
How i understand its just calling of procedure not thetself. But procedure too bit to copy it here.
AND have a table:
CREATE TABLE [BusStation](
[Id] [uniqueidentifier] NOT NULL,
[Segment_ID] [uniqueidentifier] NOT NULL,
[Dist] [decimal](18, 4) NOT NULL,
[Kod_Spr012] [smallint] NOT NULL,
[Square] [decimal](18, 6) NULL,
[OperationStartDate] [date] NULL,
[BallanceCost] [decimal](18, 6) NULL,
[DepreciatedCost] [decimal](18, 6) NULL,
[ChargesNorm] [decimal](18, 6) NULL,
[DocumentName] [varchar](100) NULL,
[DocumentNum] [varchar](100) NULL,
[DocumentDate] [date] NULL,
[Authority] [varchar](100) NULL,
[Kod_Spr091] [smallint] NOT NULL,
[HasWaysideStop] [bit] NOT NULL,
[HasLanding] [bit] NOT NULL,
[HasSpeedTransitArea] [bit] NOT NULL,
[LenSpeedTransitArea] [decimal](18, 6) NULL,
[YearBuilt] [smallint] NULL,
[YearMajorOverhaul] [smallint] NULL,
[Kod_Spr019] [smallint] NOT NULL,
[TechCond] [varbinary](max) NULL,
[LandCont] [varbinary](max) NULL,
[LandContDate] [date] NULL,
[LandContStartDate] [date] NULL,
[LandContEndDate] [date] NULL,
[Kod_Spr120] [smallint] NULL,
[E_Date_Begin] [datetime] NOT NULL,
[E_Date_End] [datetime] NULL,
[E_Date_Stop] [datetime] NULL,
Now i want to call this procedure for each row of table.
Its possible?

Answer 1

Yes, you can use a cursor that selects all the rows in the table and iteratively calls the stored procedure.
I would suggest that you may have a design issue before going down that route though. If the stored procedure needs to be called for every row in the table, you may be able to write a stored procedure that simply does what your current sp does to all the rows instead of a single row operation.
You have not provided what the sp is doing so I can only speculate here.

Answer 2

As mentioned in my comment, the only way I would know how to do that is using a CURSOR. Here is some sample code (untested of course):
DECLARE #ID INT
DECLARE #Segment_ID uniqueidentifier
DECLARE #getAccountID CURSOR
SET #BusStationCursor = CURSOR FOR
SELECT Id, Segment_ID --(etc: all the fields you need)
FROM BusStation
OPEN #BusStationCursor
FETCH NEXT FROM #BusStationCursor INTO #ID, #Segment_ID
WHILE ##FETCH_STATUS = 0
BEGIN
--CALL YOUR SP HERE
PRINT #ID
PRINT #Segment_ID
FETCH NEXT FROM #BusStationCursor INTO #ID, #Segment_ID
END
CLOSE #BusStationCursor
DEALLOCATE #BusStationCursor
This should help as well:

Good luck.
