For loading text, CSV or XML files into SQL Server, the Log Parser utility, with its amazing SQL engine, is likely to be the obvious choice. Although initially developed purely for converting IIS logs, the Log Parser can turn its hand to a range of formats including even event logs or the Windows registry.

Too often, the batch systems that underlie a lot of database processing just grow without conscious design. When runs start to extend beyond their allotted time, and tuning no longer solves the problem, it is often discovered that batches are run in series, with draconian error handling. It is time to impose some rational design, and Nigel is a seasoned healer of batch processes.

Recently while working on a project to import data from an Excel worksheet using SSIS, I realized that sometimes the SSIS Package failed even though when there were no changes in the structure/schema of the Excel worksheet. I investigated it and I noticed that the SSIS Package succeeded for some set of files, but for others it failed. I found that the structure/schema of the worksheet from both these sets of Excel files were the same, the data was the only difference. How come just changing the data can make an SSIS Package fail? What actually causes this failure? What can we do to fix it?
