# Proposed changes Issue Number: close #7570 ## Problem Summary: explode_outer(ArrayColumn) desc: > Create a row for each element in the array column. Unlike explode, if the array is null or empty, it returns null. Usage example: 1. create a table with array column, and insert some data; 2. open enable_lateral_view and enable_vectorized_engine; ``` set enable_lateral_view = true; set enable_vectorized_engine=true; ``` 3. use explode_outer ``` > select * from array_test; +------+------+--------+ | k1 | k2 | k3 | +------+------+--------+ | 3 | NULL | NULL | | 1 | 2 | [1, 2] | | 2 | 3 | NULL | | 4 | NULL | [] | +------+------+--------+ > select k1,explode_column from array_test LATERAL VIEW explode_outer(k3) TempExplodeView as explode_column; +------+----------------+ | k1 | explode_column | +------+----------------+ | 1 | 1 | | 1 | 2 | | 2 | NULL | | 4 | NULL | | 3 | NULL | +------+----------------+ ``` ## Checklist(Required) 1.
