As for the pissing match - meh. There's times to use stuff and times not to. Never been a fan of the religious fanatics on either the ALWAYSUSEIT and NEVERUSEIT sides. Both sides seem to me to substitute easy-to-remember rules in place of actually thinking about the needs of the current task.

You're totally out of line. There's no pissing match when something gets its butt kicked 45 to 1. You don't need to use inflamatory terms like "religious fanatics" when good people have found an extreme performance problem. And if you're so proud of Expresso, you might want to provide a couple of your own performance tests.

Thanks, Jeff. I was unsure what relevance the post had to a suggestion for a simple RegEx testing tool...

The next bit isn't in any way argumentative, just illustrative...

I'd add that the RegEx I use is on low row-count but high string-count-per-row data - data that's completely isolated to our custom app. Nasty stuff like pulling any and all of four possible custom operators and their parameters from a string pulled from XML built by the UI. Yuk but it works very well.

e.g.

using '\[\d+[\:\-*\d+]+\]' to shred:

WHERE site_id = 81 AND ([3154:2]-[3154:1]=0 AND [3154:3]-[3154:2]=0 AND [3154:4]-[3154:3]=0 AND [3154:5]-[3154:4]=0 AND [3154:6]-[3154:5]=0 AND [3154:7]-[3154:6]=0 AND [3154:8]-[3154:7]=0 AND [3154:9]-[3154:8]=0)

or 'DailySum\(\[\d+[\:\-*\d+]+\]\)' and '\[\d+[\:\-*\d+]+\]' to shred:

WHERE site_id = 29 AND (DailySum([1116]) > 0 or DailySum([1048]) > 0 and [1117] > 0 or DailySum([1027]) > 0 or DailySum([1026]) > 0 or DailySum([1126]) > 0 or DailySum([1141]) > 0 or DailySum([1088]) > 0 or DailySum([1090]) > 0 and DailySum([1092]) > 0 or DailySum([1128]) > 0)

Can't quite bring myself to make it go faster with custom T-SQL for the sake of a few updates per day.

Another great "it depends" article and series of comments! (EXCEPT FOR THE MORONS POLLUTING THE SITE WITH THEIR CRASS ATTEMPTS AT ATTRACTING BUSINESS - THEIR ONLY SUCCESS: ATTRACTING VILIFICATION!)
