| Impala supports several categories of built-in functions. These functions let you perform |
| mathematical calculations, string manipulation, date calculations, and other kinds of data |
| transformations directly in SQL statements. |
| </p> |
| |
| <p> |
| The categories of functions supported by Impala are: |
| </p> |
