SQL Emailing Different Rows to Different Email addresses - sql-server-2008

Question

I've written a stored procedure that runs every day and finds checks we are unable to process due to insufficient information on the check. The results of this query gives me a table with 4 columns, one of which is an email address, the three other columns being check info for the unprocessed check.
CHECK_AMT | CHECK_DATE | CUSTOMER_NAME | EMAIL_ADDRESS
So each row has information for a different check and or different customer. I want SQL to send an email to Mr/s. [EMAIL_ADDRESS] at each company [COMPANY_NAME] notifying them that they need to contact us regarding a check dated [CHECK_DATE] for $[CHECK_AMT]. Each customer can only receive an email the information for their own check, not the entire table that is being produced by the stored procedure.
I've looked at other SQL generated emails, but havent found one that sends emails this way. Any guidance on emailing information from row1 to the email address in row1, info from row2 to the email address in row2...etc.? I've only been working with sql for about 3 weeks now, so I'm still very new to everything. If anyone has any questions, I'll be happy to answer them. Thank you!

Answer 1

DECLARE
#ch_amt DECIMAL(20,2),
#ch_date DATE,
#c_name NVARCHAR(255),
#email VARCHAR(320),
#msg NVARCHAR(MAX);
DECLARE c CURSOR LOCAL FAST_FORWARD FOR
SELECT CHECK_AMT, CHECK_DATE, CUSTOMER_NAME, EMAIL_ADDRESS
FROM dbo.SomeTable
WHERE [some clause that lets you know this check was nOt processed];
OPEN c;
FETCH c INTO #ch_amt, #ch_date, #c_name, #email;
WHILE ##FETCH_STATUS = 0
BEGIN
SET #msg = N'Dear ' + #c_name + ', we could not process your check...';
EXEC msdb.dbo.sp_send_dbmail
#recipients = #email,
#subject = N'Check processing failure',
#body = #msg;
FETCH c INTO #ch_amt, #ch_date, #c_name, #email;
END
CLOSE c;
DEALLOCATE c;
This assumes Database Mail is configured and that you want to send the mail from the default profile. See the documentation for sp_send_dbmail for more info.

I'm thinking you just need a loop of some kind. Either a cursor, or a while loop, maybe something like:
declare #check_id int;
declare #email varchar(100);
declare #check_date date;
...etc...
while exists (select 1 from emails where ... and msg_sent = 0)
begin
select top 1 #check_id = check_id, #email = email, #check_date = check_date, ...
from emails
where ... and msg_sent = 0;
' Now you've got variables which you can use to send your email
update emails set msg_sent = 1
where check_id = #check_id;
end;
You can probably clean up the loop a bit to avoid doubling up the queries, but you get the idea...
