Add a new year partition before January data arrives by checking boundaries, preparing NEXT USED, splitting an empty range, and scheduling the work.
GROUPING SETS: Choose Nonhierarchical Subtotals Explicitly
GROUPING SETS lets me choose independent subtotal combinations instead of assuming one hierarchy. I list the groups the report needs explicitly. That can exclude detail rows while retaining summaries across different dimensions.
SQL SERVER – Difference Between Quality Assurance and Quality Control – QA vs QC
A Tea Time chat at our India office turned into a debate on Quality Assurance vs Quality Control. Here is a simple way to tell QA and QC apart.
EXP and LOG: Read Approximate Inverse Calculations
EXP and LOG can undo each other mathematically, but their SQL float calculations remain approximate. Keep a deliberate display scale and test only the permitted logarithm domain.
Check Constraints That Enforce Business Rules
Check constraints keep row rules inside SQL Server, but NULL behavior and trusted status determine how much protection they provide.
CEILING and FLOOR: Negative Values Change the Direction
CEILING and FLOOR follow numeric order even below zero. This example compares both boundaries with truncation and explicitly defines its displayed decimal types.
Stress Testing a Query Before Release
Stress testing a query before release reveals concurrency and parameter risks; learn to design realistic SQL Server tests and compare useful metrics.
