David Thanks
My problem comes from 6 records containing a backslash in several columns
out of a million plus rows in many different tables. I am testing some
replication software and have found that for these 6 records the
destination tables contain two backslashes after being replicated.
Source (master) record
I.e: Column data
========== ====================================
description SUBDIV LOT 13 & N1\2 LOT 14
Destination (slave) becomes the following
description SUBDIV LOT 13 & N1\\2 LOT 14
My question was more generic since I cant see why a '\' character cant be
used in a character string (I.e. storage path etc.. ). How would you
escape a \ character that is needed to be stored in a string and is there
anything special that one would have to do when retrieving it?
