from dc_tp_test T
Inner Join dc_tp_subdepartments S
on T.subdepartmentid = S.subdepartmentid
Where S.subdepartmentid = 13),sysdate(),1)

Answer 1

You cannot use subselect in just one column, use them for whole row:

INSERT INTO dc_tp_comment  (labid,branchid,Comment,testid,lastupdated,enteredby)
select 'abcd',101,'comment here', T.testid, sysdate() , 1
from dc_tp_test T Inner Join dc_tp_subdepartments S
on T.subdepartmentid = S.subdepartmentid
Where S.subdepartmentid = 13

Answer 2

Use select insted of values if you want to insert multiple rows...

Syntax would be like:

INSERT INTO dc_tp_comment  (labid,branchid,Comment,testid,lastupdated,enteredby)
select 'abcd',101,'comment here',(select T.testid
from dc_tp_test T
Inner Join dc_tp_subdepartments S
on T.subdepartmentid = S.subdepartmentid
Where S.subdepartmentid = 13),sysdate(),1
