Hi,

I am using 2 SQL Servers, 1 is a Production Server and 2 Live database server. I use to insert records in Server 1 and while inserting through VB code i generate an email that gets the data to Server 2 and inserts values there too. Now the problem is when Outlook at Server 2 gets the mail and try processing the mail from SQL Mail feature it gives error. When I use that statement and try to debug and check the hex value at DOS prompt the line where the error was given, contains line feed and caradge return, and that makes SQL Server 2 not to recognize the Query properly. Is there any feature/solution to overcome this problem.

Regards.

Are you sure SQL has pa problem with CR/LF? normal SQL is no problem.
anyway, to remove CR/LF you can use ;

replace( replace ( @Mystring, CHAR(13),''), CHAR(10), '')

Are you using xp_readmail to read the message?  @message is text datatype, not varchar, so make sure you are not just truncating the message at the length of your declared @message variable (and it just happens to end @ CRLF.)

Hi,

Well BillAn1, I am trying to use the replace function, I tried it last night, but somehow, it doesnt seem to work. Still trying. :). And yes Kselvia I am using xp_readmail, but how can I check/change the datatype of text that is in the message body. Can we apply this replace function to replace what we want in the text for xp_readmail @message variable. Kselvia, by truncating the message means deleberately applying CRLF through code? if so, no I am not doing that.

Regards.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

You will need to convert the @message variable to a varchar before you use the REPLACE function. THe risk of truncating is that varchar is maximum length of 8000 characters. If your text is longer than that you will loose the end of it.

declare @MyString varchar(8000)
set @MyString = @message
MyString = replace(replace(@MYString,char(10),''),char(13),'')

however, can youcalrify what the error is you are getting? why are you having problems wiht CRLF?

Hi BillAn1,

Well I am getting this query in mail and this is the error at the bottom of the query that I get.

insert into Quandary.dbo.cases (Company,[UPL Call No],[SR
No],Technology,Hardware,Software,System,[Problem Description],[Case
Status],Caller,[Caller Email],[Customer site],[Open
Date],Summary,Engineer,City,Component,Product,[Contract
Type],Priority,[Entered By],[Entered Time]) values ('ENI Pakistan
Ltd','ENI-410008',' ','Networking','-- N/A --','-- N/A --','fgfgsfd fsdg
gd f','sgd fg gsdfgfsdgfdg','Open','Asif Mansoor','
','Forum','09/01/2004 4:45:09 PM','fgdsfg fgf sggsdgsdfgdfgfg
fgsddf','Muhammad Akif','Karachi','12/24GB DAT Drive','Brio BA
410','Maintenance','Normal','Muhammad Akif','09/01/2004 4:45:39 PM');

ODBC error 207 (42S22) Invalid column name 'SR

No'.

What SQL xp_readmail reads after the "SR" is CRLF, I have tried several ways to avoid these characters but, was'nt able to resolve this issue, as these lines of xp_readmail doesnt allow any thing like variable assignment and applying functions while this procedure is executed.

 exec @status = master.dbo.xp_readmail
            @msg_id=@msg_id,
            @originator=@originator output,
            @cc_list=@cc_list output,
            @subject=@msgsubject output,
            @message=@query output,
            @peek='true',

these are the lines that I got from sp_processmail, I think the last variable assignment and function application solution you mentioned does'nt fit here.

I have asked my programers to apply some changes at there code to getrid of these CRLF special characters. Lets see what they comeup with. If this replace function would have been worked here properly, it would have been a great stored procedure, no worries at all.

Regards.

Yes, if CRLF are actually in the middle of calumn names etc, it will cause a problem.

From the look of the data you have here, I think what you need is to replace CRLF with a space  
e.g. is the correct name of the column [SR No] ?
in your email it is [SR{CR}{LF}No]

try this (replace the print with EXEC when you are happy) - it replaces CR with ' ' and LF with ''

declare @q2 varchar(2000)
set @q2 = replace(replace(@query,char(13), ' '), char(10), '')
print @q2
---exec (@q2)

 this give the following result, which looks OK to me:

insert into Quandary.dbo.cases (Company,[UPL Call No],[SR No],Technology,Hardware,Software,System,[Problem Description],[Case Status],Caller,[Caller Email],[Customer site],[Open Date],Summary,Engineer,City,Component,Product,[Contract Type],Priority,[Entered By],[Entered Time]) values ('ENI Pakistan Ltd','ENI-410008',' ','Networking','-- N/A --','-- N/A --','fgfgsfd fsdg gd f','sgd fg gsdfgfsdgfdg','Open','Asif Mansoor',' ','Forum','09/01/2004 4:45:09 PM','fgdsfg fgf sggsdgsdfgdfgfg fgsddf','Muhammad Akif','Karachi','12/24GB DAT Drive','Brio BA 410','Maintenance','Normal','Muhammad Akif','09/01/2004 4:45:39 PM')
