For the code, you'll really need to post the DDL of the tables involved, and some insert statements for the sample data.

For the general outline, you're looking at some date functions to group the data to month/year, an aggregation using a group by, and a pivot to send the data sideways.

The requested output is not really something you should expect from a SQL statement:

a) It seems like you want to have "flexible column names" for each row which is totally against any kind of relational database concept. A table has a column with a name and a value per row.

b) It also seems you're looking for a flexible number of columns holding the same type of information (e.g. Total for ID) in different columns depending on the value of the original column total_month.

You might want to rethink the requirement you're looking for. To split data in the way you describe shouldn't be done using T-SQL. It's a front end task. What you could do on the SQL side is a query to return ID, column number, column name and column value. At the front end, design a layout to get the column name and related column value per ID ordered by column number.

It is possible to do it using T-SQL (even including a blank row between each statement). But that would be like banging a nail into a wall with a screwdriver: possible, but not recommended. Get the right tool for the job! 😉

The others are correct about the links on how to provide data. That, notwithstanding, please see the following link for a coded example of what you want to do. Wayne points to the same link, as well. http://www.sqlservercentral.com/Forums/Topic986540-391-1.aspx

I absolutely agree with what you say but consider the following... what if there is no "front end" for this task?? 😉 Remember... to a nail, everything is a hammer. 😛

Assuming I'd be forced to come up with a result in a format as requested but without any front end app, I'd probably do it this way (for a static solution and as a starting point to have something to turn into dynamic sql)

DECLARE @tbl TABLE

(

ID INT,

total_amt INT,

total_month INT,

start_date DATETIME

)

INSERT INTO @tbl

SELECT 1,1200000,6,'9/14/2009' UNION ALL

SELECT 2, 300000,3,'1/1/2006' UNION ALL

SELECT 3, 300000,10,'9/6/2006'

;

WITH cte AS

(

SELECT

ID,

N+1 AS Pos,

STUFF(CONVERT(CHAR(11),DATEADD(mm,N,start_date),0),4,6,'''') AS col1,

total_amt/total_month AS amt_mnth,

total_amt

FROM @tbl t

CROSS APPLY

(

SELECT number N

FROM master..spt_values

WHERE TYPE='P'

AND number < total_month

)x

)

SELECT

CASE WHEN grp=3 THEN '' ELSE CAST(ID AS VARCHAR(10)) END AS ID_,

-- one sample row to show the nest level of the CASE statements

MAX(

CASE

WHEN Pos=1 THEN

CASE

WHEN grp= 1 THEN col1

WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10))

ELSE ''

END

ELSE ''

END) AS [ ],

MAX(CASE WHEN Pos=2 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=3 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=4 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=5 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=6 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=7 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=8 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=9 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ],

MAX(CASE WHEN Pos=10 THEN CASE WHEN grp= 1 THEN col1 WHEN grp= 2 THEN CAST(amt_mnth AS VARCHAR(10)) ELSE '' END ELSE '' END) AS [ ]

FROM cte

CROSS APPLY

(

SELECT 1 AS grp UNION ALL -- display the month

SELECT 2 UNION ALL -- display the value per month

SELECT 3 -- empty row

) y

GROUP BY ID,grp

ORDER BY ID,grp

/* result set

You can make if stamment

IF (SELECT COUNT(Months) FROM tablename

after

declare the amount of each months (you make specific that some months are different amounts)

begin and end store procedure...should be work fine...

LutzM SSC Guru Points: 107049 More actions · Answer 12

... and here's the version to include the total amount right after the last month, based on the sample posted before.

;

WITH cte AS

(

SELECT

ID,

N+1 AS Pos,

STUFF(CONVERT(CHAR(11),DATEADD(mm,N,start_date),0),4,6,'''') AS col1,

total_amt/total_month AS amt_mnth

FROM @tbl t

CROSS APPLY

(

SELECT number N

FROM master..spt_values

WHERE TYPE='P'

AND number < total_month

)x

UNION ALL

SELECT

ID,

total_month + 1 AS Pos,

'total' AS col1,

total_amt AS amt_mnth
