SQL insert statement - FILL null values for all columns except some - sql

Question

I have an insert statement where I only need to fill 15 columns out of 70 - and all the other columns can remain NULL. I would like to find a way to write this statement in a shorter matter without having to write all the null as etc etc
INSERT INTO my_table
SELECT
division_id
,sub_division_id AS sub_division_id
,store
,store_id AS store_id
,store_address
,zip_code
,'202306' AS week
,'2023-02-02' AS date
,'Type' AS type
,'other_string' AS blah
,'Name' AS Name
,NULL AS unimportant_column
,NULL AS unimportant_column_2
,NULL AS unimportant_column_3
,NULL AS unimportant_column_4
,NULL AS unimportant_column_5
,NULL AS unimportant_column_6
,NULL AS unimportant_column_7
,NULL AS unimportant_column_8
,household_id
,NULL AS unimportant_column_9
,NULL
,NULL
,id
,email AS emailaddress
,token

,NULL as edyd
FROM some_table x
where flag1 = 1
and flag2 = 7
GROUP BY 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42
,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69 ;
I want it to be something like this
INSERT INTO my_table
SELECT
division_id
,sub_division_id AS sub_division_id
,store AS Store
,store_id AS store_id
,store_address as store_nm_addr
,zip_code as zip_code
,'202306' AS week
,'2023-02-02' AS date
,'TYPE' AS TYPE
,'other_string' AS blah
,'Name' AS name
,household_id as household_id
,id as ID
,email AS emailaddress
,token_txt as token
FROM some_table x
where flag1 = 1
and flag2 = 7
;
Ofcourse this does not work as you get this error:
SQL compilation error: Insert value list does not match column list expecting 70 but got 15
But what would be a way to insert just the values you need and default the rest to null values? The "my_table" table must have 70 columns - even though the values in the other columns are null

Answer 1

The problem with your current insert is that if you do not specify any column names then it defaults to expecting all columns. If you explicitly list out the target columns you want, then the omitted names will default to receiving a null value.
INSERT INTO my_table (division_id, sub_division_id,
Store, store_id, store_nm_addr, zip_code, week, date, TYPE, blah, name,
household_id, ID, emailaddress, token)
SELECT
division_id,
sub_division_id,
store,
store_id,
store_address,
zip_code,
'202306',
'2023-02-02',
'TYPE',
'other_string',
'Name',
household_id,
id,
email,
token_txt
FROM some_table x
WHERE flag1 = 1 AND flag2 = 7;
