24+
|:-------------|:-------------------------------------------------------------------------------------------------------------------------------|
25+
|`ARRAY_LENGTH(json)`|If the json representation is an array, this function returns its size.|
26+
|`AVG(expr)`|Returns the average value of expr in all rows.|

30+
|`CONCAT(...)`|Concatenate any group of fields into a single string.|
31+
|`CONCAT_WS(sep, ...)`|Concatenate any group of fields into a single string. The first argument is the separator for the rest of the arguments. The separator is added between the strings to be concatenated. The separator can be a string, as can the rest of the arguments. If the separator is NULL, the result is NULL.|
32+
|`CONNECTION_ID()`|Return the current connection ID.|

60+
|`ROUND(number, decimals)`|Round the `number` to `decimals` decimal places.|
61+
