 ## FOREACH
 
 ### description
-#### Syntax
 
-`AGGREGATE_FUNCTION_FOREACH(arg...)`
 Converts an aggregate function for tables into an aggregate function for arrays that aggregates the corresponding array items and returns an array of results. For example, sum_foreach for the arrays [1, 2], [3, 4, 5]and[6, 7]returns the result [10, 13, 5] after adding together the corresponding array items.
