# Basic built-in functions
Below are the general-purpose functions.
## COALESCE {#coalesce}
Iterates through the arguments from left to right.
#### Examples
```yql
SELECT COALESCE(
maybe_empty_column,
"it's empty!"
) FROM my_table;
```
## Random... {#random}
Generates a pseudorandom number:
* `Random()`: A floating point number (Double) from 0 to 1.
* `RandomNumber()`: An integer from the complete Uint64 range.
* `RandomUuid()`: [Uuid version 4](https://tools.ietf.org/html/rfc4122#section-4.4).
#### Signatures
```yql
Random(T1[, T2, ...])->Double
RandomNumber(T1[, T2, ...])->Uint64
RandomUuid(T1[, T2, ...])->Uuid
```
No arguments are used for random number generation.
#### Examples
```yql
SELECT
Random(key) -- [0, 1)
FROM my_table;
```
