How many of you DBAs are stuck working in an environment where LINQ and/or the Entity Framework are used? I fully appreciate that these things make the lives of developers much easier but I'm regularly running into scenarios where application performance is suffering because LINQ is being translated into sub-optimal TSQL. In fact, I've just been told by a developer that the "StartsWith" LINQ construct that is being translated into a CHARINDEX = 1 instead of a LIKE 'blah%' is a known limitation and there is no workaround. My index is being ignored because of this.

Frustration mounting.......

This was a huge problem at my last job. I tried to make stored procedures a requirement but lost that battle. Thankfully I'm now in an environment where the DBAs do have the power. I'm much happier.
