MySQL How do you INSERT INTO a table with a SELECT subquery returning multiple rows?

  INSERT INTO Results
    (
     People,
     names,
    )
    VALUES
    (
     (
       SELECT d.id
       FROM Names f
       JOIN People d ON d.id  = f.id
     ),

     (
      "Henry"
     ),
    );

I WANT to populate the new table with all results returning from this subquery. How do I do this without getting a ERROR 1242 (21000): Subquery returns more than 1 row

INSERT INTO Results (People, names )
   SELECT d.id, 'Henry'
   FROM Names f
   JOIN People d ON d.id  = f.id

Combine the static string Henry with your SELECT query.

INSERT INTO Results
    (
     People,
     names,
    )
    VALUES
    (
     (
       SELECT d.id
       FROM Names f
       JOIN People d ON (d.id  = f.id) limit 1
     ),

     (
      "Henry"
     ),
    );

Here is what I've found that works well. It is a little long but many times extra data needs to be shuffled around.

Insert multiple rows into table1 from table2 with values. EXAMPLES:

INSERT INTO table1 (col1, col2, col3, col4, col5) 
SELECT col1,col2,col3,col4,col5 
FROM table2 t2 
WHERE t2.val2 IN (MULTIPLE VALUES) 
AND (Another Conditional);

You can insert hard coded values to get insert multiple rows with repeat data:

INSERT INTO table1 (col1, col2, col3, col4, col5) 
SELECT "Value", col2, col3, "1900-01-01","9999-12-31" 
FROM table2 t2 
WHERE t2.val2 IN (MULTIPLE VALUES) 
AND (Another Conditional);

Note that: "Value","1900-01-01","9999-12-31" will repeat across all rows inserted.

  INSERT INTO Results
    (
     People,
     names,
    )
    SELECT d.id, 'Henry'
    FROM Names f
    JOIN People d ON d.id  = f.id

The reason of this error (Subquery returns more than 1 row) is that you use parenthesis (). Look more careful to the best answer. It doesn't contain parethesis around subquery

In MySql multiple values from strings can be inserted like the following avoiding duplicates. Thanks.

   insert into brand(name) select * from ( 
select 'Fender' as name 
union select 'a' 
union ..... ) t 
where not exists (select 1 from brand t2 where t2.name COLLATE latin1_general_ci = t.name COLLATE utf8mb4_unicode_ci )

insert into ec_element(parentid,name) select elementid , 'STARTUP' from ec_element where name = 'BG';

insert statement takes values elementid from the table found with condition fulfilled and a label string.
