使用 where IN 子句从多个表中删除记录

Question

I want to delete data from 2 tables based on plan id which comes from the plan_temp table using WHERE IN .. I would be very grateful if you guys help me

this is my code now I want to make this a single query

DELETE FROM plan WHERE id_plan IN(SELECT id_plan FROM plan_temp WHERE no=1184);


DELETE FROM plan_temp WHERE id_plan IN(SELECT id_plan FROM plan_temp WHERE no=1184);

Answer 1

Use an INNER JOIN to find the rows in both tables

DELETE t1,t2 FROM plan t1
        INNER JOIN
    plan_temp t2 ON t2.id_plan = t1.id_plan 
WHERE
    t1.id_plan IN (SELECT id_plan FROM (SELECT * FROM plan_temp) t3 WHERE no=1184);

Please test all queries in a test environment with backup, to see if this is really what you want

Answer 2

Unfortunately, you can't delete two separated tables.

DELETE FROM plan WHERE id_plan = 1184

DELETE FROM plan_temp WHERE id_plan = 1184

But, you can use Inner Join to delete both values from two tables. So, it has to be like that;

DELETE  plan, plan_temp FROM plan INNER JOIN plan_temp
Where
plan.id_plan = plan_temp.id_plan and id_plan = 1184;
