SQL Logical Operators
AND, OR, and NOT, side by side — the three ways to combine or flip conditions.
What & Why
Every filtering condition beyond a single comparison is built from these three: AND (every condition must hold), OR (at least one must hold), NOT (flip a condition's truth value).

REFERENCE EXAMPLE
| Operator | Row survives when... |
|---|---|
| AND | every condition is true |
| OR | at least one condition is true |
| NOT | the wrapped condition is false |
The result uses the same Queryflo columns shown in the worked example.
