Selecting special characters

Hello,

I have a number of columns in my dataset one/or more of which I believe might have an embedded special character such as a CR or LF. I have tried using the following in my query:

patindex('%' + char(13) + '%' , texfield) > 0 to no avail. I have also tried charindex with the same result.

I know that the special character is there because when I export the data out to text somewhere along the way the records gets truncated into two.

I would like to be able to locate this special character and strip it out. Any suggestions.

My next step is to write a VB program to go through the dataset.

Thanks
Eddie

Try something like this:
PATINDEX('%[^0-9][^A-Z][^a-z]%', textfield) > 0

To give you non-alpha-numeric characters.

Or to give you non-printable characters, something like:
PATINDEX('%[^ - Ç]%', textfield) > 0
0

ACPerkins,

Thanks for your quick response. Is the line
PATINDEX('%[^0-9][^A-Z][^a-z]%', textfield) > 0
meant to look for anything that is not 0-9 A-Z and a-z ?

Yes.  Unfortunately it gets more complicated as I have discovered with other ranges.  Please disregard the second "solution" it is incorrect. For some reason that I have not managed to ascertain, it simply does not function (at least for me) with anything beyond the trivial non alphanumeric characters.

You may have to resort to using a cursor and cycle through all the rows. Looking for non-printable characters. Ugh!

Hopefully, someone will step in.
