Featured Article: Fast CSV Import in PowerShell to SQL Server

I recently had to write some simple scripts for a proof of concept. These scripts use PowerShell to import and export CSV files from SQL Server. The scripts were simple to write and maintain but were slow. It turns out there are a few ways to improve CSV import and export performance in PowerShell.

Using Dynamic SQL in Stored Procedures

Dynamic SQL allows stored procedures to “write” or dynamically generate their SQL statements. The most common use case for dynamic SQL is stored procedures with optional parameters in the WHERE clause. These are typically called from reports or screens that have multiple, optional search criteria. This article describes how to write these types of stored procedures so they execute well and resist SQL injection attacks.

Testing with Profiler Custom Events and Database Snapshots

We've all had them. One of those stored procedures that is huge and contains complex business logic which may or may not be executed. These procedures make it an absolute nightmare when it comes to debugging problems because they're so complex and have so many logic offshoots that it's very easy to get lost when you're trying to determine the path that the procedure code took when it ran. Fortunately Profiler lets you define custom events that you can raise in your code and capture in a trace so you get a better window into the sub events occurring in your code. I found it very useful to use custom events and a database snapshot to debug some code recently and we'll explore both in this article. I find raising these events and running Profiler to be very useful for testing my stored procedures on my own as well as when my code is going through official testing and user acceptance. It's a simple approach and a great way to catch any performance problems or logic errors.
