SQL Server's COUNT() function is a slow and expensive way to count a table's rows because it scans the entire table or index. FASTCOUNT(), which I created, is much more efficient for this purpose - its only drawback being that it may return inaccurate results if a nonlogged (e.g., bulk) data modification operation was recently […]

When altering the structure of tables it is good practice to run SP_RECOMPILE against the table to force triggers and stored procedures to recompile. However this does not incude Udf's which also rely on the table, and this means the Udf's may fail when they are called. Run this script and supply the table name […]
