Importing Text-based data: Workbench

Robyn and Phil return with some fresh ideas about how to import text files into SQL Server, without resorting to DTS or SSIS scripting. They go on to show how much can be done in TSQL

Script foreign keys

Using this script you can create a list of sql commands for foreign keys manipulation.

Bit Manipulation Functions (4)

Working with Time Spans and Durations in SQL Server

What is the best way to return the "duration" of an event in SQL, given the start and end datetime values? How can we add up these durations to return grand totals? What data types should be used to return this data to our clients? How do we handle overflows, such as when hours go over 23 or minutes total up to over 59? Are there any T-SQL functions or other techniques that are useful in these scenarios?

A New (and Hopefully Better) Approach to Constants

A look at how constants are used in T-SQL and SQL Server in general along with some suggestions on how better to deal with them.
