< SQL Dialects Reference#### Trigonometric functionsEdit

This page includes **comparison tables** which can be **big and complex**.

While it's perfectly all right to view them in their complete state, it is recommended to install a comparison tables extension that would allow to select particular columns of interest for comparison.
