How best to create a specific file with header and footer incorporating modified select data
Hi
I've got to produce on a daily basis an export file to upload to a payment provider. I'm pulling my data back initially using the following SQL which lists the uprn and price Any ideas for the best way forward? Its well beyond my SQL knowledge but I guess if there is no luck here I could try it all in PHP.
Which gives me a file approximately 64372 lines long containing data like this (uprn/price in pence):
Now, I need to wrap this with a header and footer. The header is quite easy as its preset with just the date (in bold) changing:
The footer however is trickier as its preset in part but requires the date again then the total number of records, then the amount of all the prices totalled up

SELECT b.c_uprn,
g.green_uprn
CASE
WHEN g.green_uprn IS NOT NULL THEN 10.00
ELSE 20.00
END price
FROM t_blpu b
LEFT OUTER JOIN t_refuse_garden_2014 g ON b.c_uprn = '0000' + g.green_uprn
ORDER BY
g.green_uprn DESC
Which gives me a file approximately 64372 lines long containing data like this (uprn/price in pence):
40121018 3895
40118160 3895
40117792 3895
40117638 3895
40117634 3895
40117633 3895
40117629 3895

H,242,[b]20140727 16:07:00[/b],F,14,7.0
The footer however is trickier as its preset in part but requires the date again then the total number of records, then the amount of all the prices totalled up
T,242,[b]20140727 16:07:00[/b],[b]64372[/b],[b]395828570[/b],0

Use SQL's bcp utility to separately create the three files, then use a standard DOS/Windows command file to concatenate the files.
Bcp is a command-line utility and is a pain to get working the first time. But once you've got it going, it's not that bad. Here's sample code to use bcp to create the header file.
DECLARE @bcp_command varchar(8000)
DECLARE @header_file varchar(500)
DECLARE @body_file varchar(500)
DECLARE @footer_file varchar(500)
SET @header_file = 'C:\header.txt'
SET @bcp_command = 'bcp "SELECT ''H,242,' +
CONVERT(varchar(8), GETDATE(), 112) + ' ' + CONVERT(varchar(8), GETDATE(), 8) +
',F,14,7.0''" queryout "' + @header_file + '" -r\r\n -S server\instance -t, -T -w'
PRINT @bcp_command
EXEC xp_cmdshell @bcp_command
EXEC xp_cmdshell 'type "c:\header.txt"'
EXEC xp_cmdshell 'del "c:\header.txt"'
[Btw, if you do use SQL to concatenate the data, you'd want to use UNION ALL not UNION.]
