I'd like to update table1 based upon a sum principally applied on table2 but including a single value from table 3.
我想基于主要应用于table2但是包含表3中的单个值的总和来更新table1。
table2 has a column that's FKd to table1's id column, and the sum is based upon them matching.
table2有一个列为FKd到table1的id列，并且总和基于它们的匹配。
UPDATE table1, table2
SET table1.column1 =
(SELECT SUM( (SELECT constant FROM table3) +
(SELECT table2.sum_number
WHERE table2.table2_id1 = table1.id) ) )
WHERE table1.id = table2.table2_id1;
That doesn't work for me.
这对我不起作用。
Many thanks in advance!
提前谢谢了！
