![]() ![]() I would give credits to who answered my question, where I get the algorithm from. ![]() INNER JOIN table3 USING (sku) ORDER BY sku, date Introduction to MySQL derived tables A derived table is a virtual table returned from a SELECT statement. (SELECT * FROM table1 UNION ALL SELECT * FROM table2 ORDER BY sku, date) union_table GROUP BY sku, date An Essential Guide to MySQL Derived Tables Summary: in this tutorial, you will learn about the MySQL derived tables and how to use them to simplify complex queries. I have the following solution, which gives the desired result, except the values for the days that there is no entries for: set date, sku, total, CATEGORY FROM INSERT INTO `Table3`(sku, CATEGORY)VALUES INSERT INTO `Table2`(date, sku, qty)VALUES INSERT INTO `Table1`(date, sku, qty)VALUES (SELECT date(date) as date, idItem, ifnull(Sum(qty),0) as qtyīut that does not give me the a line if there is no entry in both table1 and table2ĮDIT: Replaced Table1 on second table INSERT. Select date, sku, ifnull(sum(qty),0) as qty FROM( ![]() T3.category as := if( = t1.sku, + + ifnull(t1.qty,0)), ifnull(t1.qty,0) ) as := t1.sku mysql> SELECT -> f.id, -> f.name, -> tmp.favoriteMeal -> FROM -> ( -> -> ( SELECT 1 AS id, 'Pizza' AS favoriteMeal ) UNION ALL -> ( SELECT 4 AS id, 'Bella's Chicken Burrito' AS favoriteMeal ) UNION ALL -> ( SELECT 5 AS id, 'Vegan, Multi-Grain Pancakes' AS favoriteMeal ) -> -> ) AS tmp -> INNER JOIN -> friend f -> ON -> f.id tmp.id. SELECT t6.date, t6.SKU, t6.Category, t6.qty FROM I need a line for all days - even if there is no lines for that day/sku in table1 and table2 QTY of item = QTY of item of day before + sum of qty in both tables A table reference can be aliased using tblname AS aliasname or tblname aliasname: SELECT t1.name, t2.salary FROM employee AS t1 INNER JOIN info AS t2 ON t1.name t2.name SELECT t1.name, t2.salary FROM employee t1 INNER JOIN info t2 ON t1.name t2.
