Hi!! Thanks a lot for all the advices, I knew i could always get help from the lists. Had festival so couldn't reply earlier and we were closed. I have parallel question, I read about regular expressions being faster than the 'like', is it correct and one more thing how do u extract information from a given regular expression eg: like in perl anything inside the () can be extracted into a variable like... # Program Segment Starts here $disksize = $1 if (/Storage Swap size:\s+([-0-9\.]+)\s+MB/); # Program segment ends here as u can see the '$1' has the value of the expression thats got evaluated. Now my question is when i use the same in a SQL statement all I can get is just a boolean value whether it evaluates to true or false , nothing more than that. I would like to extract the value from the evaluated regular expression in a SQL query Is that possible? Thanks in advance...
