How to insert values into a table from a select query in PostgreSQL?

Solutons:


Column order does matter so if (and only if) the column orders match you can for example:

insert into items_ver
select * from items where item_id=2;

Or if they don’t match you could for example:

insert into items_ver(item_id, item_group, name)
select * from items where item_id=2;

but relying on column order is a bug waiting to happen (it can change, as can the number of columns) – it also makes your SQL harder to read

There is no good ‘shortcut’ – you should explicitly list columns for both the table you are inserting into and the query you are using for the source data, eg:

insert into items_ver (item_id, name, item_group)
select item_id, name, item_group from items where item_id=2;

dbfiddle here

INSERT INTO test_import_two (name, name1, name2) 
(SELECT name, name1, name2 FROM test_import_one WHERE id = 2)

For same table

INSERT INTO test_import_three (id1, name1, name2) 
(SELECT 216 ,name1, name2 FROM test_import_three WHERE id = 4)

INSERT INTO gate_pass(
     site_id, gate_pass_element, sequence_no, createdby, createddate, lastmodifiedby, lastmodifieddate)
SELECT 1,   gatepasselement, 3, 1,now(),1,now()  
FROM unnest(string_to_array('Bhushan,Amol,pallavi', E',')) as gatepasselement;
