Application for "Replaying" a Table

I'm on a quest to find a way to "replay" a selected time range of records
from a table. The purpose is to simulate the pace and content of the records
in the table exactly as they were parsed during run-time. The ideal solution
would read records from a source table and write them to a destination table
as per a specified pace, i.e clock speed, 1/2 clock speed, 4x clock speed.

Just looking to see if there's something available currently before I jump
in and develop my own solution.

Thanks,

ChrisYou can get about 85% of what you want from SQL Profiler, although it doesn't quite get you there without some help in the form of a small app... You might even be able to do this with a SQL script, but that would be much more of a challenge.

-PatP|||SQL Profiler isn't going to help him replay the activity. He wants some kind of load simulator.|||Yeah, a tool something like LoadRunner (http://www.mercury.com/us/products/performance-center/loadrunner/) would be ideal, but you can get better than 85% of the way there using SQL Profiler to record the data into a table, then a small app to play the captured activity into another database. Not everybody has deep enough pockets to make load testing tools a snap decision... Most of us need to budget for them, sometimes for a couple of years before we get the cool toys to play with. Having a simple kludge like I've described to show what you can do with this kind of tool makes it a lot easier to sell!
