SQL SERVER – How to Retrieve TOP and BOTTOM Rows Together using T-SQL
Need TOP 1 and BOTTOM 1 in one result? UNION fails with two ORDER BY clauses. Here is a simple T-SQL way to retrieve TOP and BOTTOM Rows together.
SIN and COS: Use Radians for Trigonometric Inputs
SIN and COS read angles in radians and return float. These explicit degree conversions show signs, axis angles and fractional results at a chosen decimal display scale.
