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.

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.
