例如：SELECT AVG(IFNULL(column_name, 0)) FROM table_name;
例如：SELECT AVG(CASE WHEN condition1 THEN column_name ELSE 0 END) FROM table_name;
例如：SELECT AVG(DISTINCT column_name) FROM table_name;
例如：SELECT AVG(subquery.column_name) FROM (SELECT * FROM table_name WHERE condition) AS subquery;
例如：SELECT column_name, AVG(value) FROM table_name GROUP BY column_name;
通過以上高級應用技巧，可以更靈活地進行average計算，并根據實際需求進行定制化的數據處理。
