Calculate linear regression slope, intercept, monthly predictions, and R-squared in T-SQL while keeping extrapolation limits clear.
The Columnstore Delta Store: Small Loads and Open Rowgroups
Inspect the columnstore delta store, distinguish rowgroup states, and choose load sizes or targeted compression after small loads.
Ordered Clustered Columnstore Index for Better Rowgroup Elimination
Build an ordered clustered columnstore on SaleDate, compare segment ranges and skipped segments, and review how later loads affect order.
Histogram Buckets in T-SQL: Counting Values per Range
Create histogram buckets in T-SQL with fixed widths or explicit ranges, retain empty buckets, and display scaled text bars.
Case-Insensitive Unique Constraints in a Case-Sensitive Database
Enforce case-insensitive unique user names in a case-sensitive database using an indexed computed column with an explicit collation.
Oversized varchar Columns and Inflated Memory Grants
Investigate oversized varchar declarations, compare sort memory grants, and narrow string columns safely without losing valid data.
Repeatable Test Data With a Fixed Random Seed
Generate repeatable test data with a fixed RAND seed or row-number hashes, then verify identical names and amounts across runs.
