Sorry, but we can't see your screen and we can't read in your mind... ;(
Please, be moe specific and provide more details.

1. You would have to show your code so we don't have to guess.
2. What are you doing that requires you to process that much through a reader? Perhaps there is a better way.

OK, so now you have added an error? What does the error have to do with getting only 1000000 records?
You need to fix the syntax error.

Try adding a space between values and (

You're problem is that you're building a SQL queery string using string concatenation. If your data that your building the string with has a "'" character in it, it'll screw up your query string.

Google for "C# SQL parameterized query" for how to fix this and why what you're doing is such a high security risk.

By the way, you don't need the "@" characters in front of your s[] array variables.
