Question

I want to do something like this

Insert into abc(col1, col2, col3) select col1, 1, col3 from xyz where somecondition
Insert into abc(col1, col2, col3) select col1, 2, col3 from xyz where somecondition
Insert into abc(col1, col2, col3) select col1, 3, col3 from xyz where somecondition
Insert into abc(col1, col2, col3) select col1, 4, col3 from xyz where somecondition
...

So there is only second column value that is changing and all else are same.

Is there any better or compact way to do the above?
May be something in one query!

I am using MySql

Edit:

I am using this inside a stored procedure.

Answer 1

If somecondition is the same and you need sequential numbers for col2 you can do following:

INSERT INTO abc(col1, col2, col3)
SELECT col1, @n := @n + 1, col3
FROM xyz, (SELECT @n:= 0) n
WHERE somecondition

UPDATE

If your WHERE conditions applied to xyz ensures that only one row will be returned and your xyz table has more than 9 records (although you can CROSS with any other table) you can leverage CROSS JOIN AND LIMIT to replicate your row N (9 in the example) times with single INSERT-SELECT statement like this:

INSERT INTO abc(col1, col2, col3)
SELECT t1.col1, @n := @n+1, t1.col3 
  FROM xyz AS t1 CROSS JOIN xyz AS t2,(SELECT @n:= 0) n 
WHERE t1.col2=2 LIMIT 9
