Determine the row of data in a table through SSIS

Hi,

I have a requirement based on 2 parts to determine a row of data in a table through SSIS :

a. Work out the LEG_SEQ_NBR of the VESSEL, VOYAGE and LEG already stored in table1.
To do this join table1 and join table2 through BL_ID column.

b. Work out the 2ndVESSEL, 2ndVOYAGE and 2ndLEG.

Once we have identified the LEG_SEQ_NBR of the VESSEL,VOYAGE, LEG already stored in table1 we need to add '1' to this value and then find that LEQ_SEQ_NBR in table2.

The DDL of table1 and table2 along with the test data are as below:

------------------------------------------------------------
CREATE TABLE [dbo].[table1](
[BL_ID] [decimal](10, 0) NOT NULL,
[VESSEL] [nvarchar](10) NULL,
[VOYAGE] [nvarchar](12) NULL,
[LEG] [nchar](3) NULL,
[BLNO] [nvarchar](17) NULL

) ON [PRIMARY]

CREATE TABLE [dbo].[table2](

[BL_ID] [numeric](10, 0) NULL,
[LEG_SEQ_NBR] [numeric](3, 0) NULL,
[VESSEL_CD] [varchar](10) NULL,
[VOYAGE_CD] [varchar](12) NULL,
[LEG_CD] [char](1) NULL,

) ON [PRIMARY]

INSERT INTO [table1]
VALUES('1','CEUR','032E','E','21')

INSERT INTO [table2]
VALUES('1','1','CEUR','032E','E')

INSERT INTO [table2]
VALUES('1','2','MARB','794S','S')
---------------------------------------------------------

For Example:

BLNO = 21 and BL_ID = 1

Current Vessel/Voyage/Leg in table1 = CEUR 032E E

LEG_SEQ_NBR of this Vessel/Voyage/Leg in table1 = '1'

Therefore if we add '1' to this value we'd be looking for LEG_SEQ_NBR '2' as the 2ndVESSEL,2ndVOYAGE,2ndLEG.

In this case that would = MARB 794S S

Does somebody pls know how this can be worked out through an SSIS job ?

Thanks.

I'm not sure I'm understanding the requirement, but maybe this will help:

SELECT
	*
FROM
	(
		SELECT 
			Table2.VESSEL_CD,
			Table2.VOYAGE_CD,
			Table2.LEG_CD,
			ROW_NUMBER() OVER (PARTITION BY Table2.BL_ID ORDER BY Table2.LEG_SEQ_NBR) AS RowNum
		FROM 
			Table1
		INNER JOIN
			table2
			ON Table1.BL_ID = Table2.BL_ID
	) AS T
WHERE 
	RowNum = 2

Or this?
[CODE]

DECLARE @LegSN numeric;
DECLARE @BL_ID Numeric;
SELECT @LegSN = [LEG_SEQ_NBR], @BL_ID = T1.BL_ID FROM Table2 T2 inner join Table1 T1 on T1.BL_ID = T2.BL_ID and VESSEL = VESSEL_CD and VOYAGE = VOYAGE_CD;
SELECT @LegSN;
SET @LegSN = @LegSN + 1;
SELECT * FROM Table2 where [LEG_SEQ_NBR] = @LegSN and BL_ID = @BL_ID;

[/CODE]

As per what I understood this is what you're after


SELECT 
			Table2.VESSEL_CD,
			Table2.VOYAGE_CD,
			Table2.LEG_CD,
                        Table1.[VESSEL],
                        Table1.[VOYAGE],
                        Table1.[LEG],
                        t1.[VESSEL] AS [2ndVESSEL],
                        Table1.[VOYAGE] AS [2ndVOYAGE],
                        Table1.[LEG] AS [2ndLEG]

		FROM 
			Table1
		INNER JOIN
			table2
			ON Table1.BL_ID = Table2.BL_ID
                INNER JOIN 
                        table2 t1
                        ON t2.LEG_SEQ_NBR = table2.LEG_SEQ_NBR + 1
                INNER JOIN 
                        table1 t1
                        ON t1.BL_ID = t2.BL_ID

Thanks very much for your code, it worked !! Sorry for the very late reply though.
