My application was working fine for quite some time. After installing service pack 5, a few of my select statements stopped working on certain machines. Of course, it was working on my machine prior to distributing the exe to my client, but quit working on my one of my client's machines, yet worked on other client's machines. It was working on ALL machines prior to the update. Has anyone experienced this? If so, do you know what is causing the sudden difference on different machines? It doesn't matter whether the selection is based on a character or number. set ansi is on and set exact is on. If the client has not updated to MDAC 2.6, would this effect data selects?
