If I understand you right: 1. You have a column which contains blocks of text, which may be multi-line. 2. You want to find out how many of those lines match a given pattern? Or you just want to extract those lines? A function using pl/perl looks like your best bet. Perl regular expressions could do what you want quite easily. --- Bhuvan A <bhuvansql@yahoo.com> wrote: > > Thu Jan 17 10:26:49 IST 2002 > ---------------------------- > > Hello, > > How can i apply a delimiter, in pattern matching on > database columns? > > say, in my table i have a column of type 'text' and > each of its value > is MULTIPLE lines. > > Now, i would like to search for a string in (say > delimiter is '\n') > that column and it should result in that many > MATCHED LINES instead of > that many matched columns. > > How can i achieve this?
