INSERT with Multiple select SQL - sql-server

Question

I'm using SQL Server 2008. I'm trying to insert data into dv_user_akun table with value that I've selected from another table. Please take a look.
INSERT INTO dv_user_akun (user_id, nik, username, password, kode_tipe, flag)
SELECT
(SELECT
CASE
WHEN right(max(user_id), 8) IS NULL
THEN 'USR00000001'
ELSE ('USR-' + RIGHT('0000000' + cast(right(max(user_id), 7) + 1 as nvarchar), 7))
END user_id
FROM
dv_user_akun) as user_id,
(SELECT
Nip, Nip, '81dc9bdb52d04dc20036dbd8313ed055', PositionCode, 1
FROM
Employee
WHERE
Nip NOT IN (SELECT Nik FROM dv_user_akun))
I get this error
The select list for the INSERT statement contains fewer items than the insert list.
The number of SELECT values must match the number of INSERT columns.

Answer 1

You don't have anything in your select statement. I've changed your subqueries to proper joins rather than the old style ansi joins that you have there. The only problem I still have is that you appear to be using the field Nip to insert into both nik and username fields;
INSERT INTO dv_user_akun (user_id, nik, username, password, kode_tipe, flag)
SELECT
a.user_id
,b.Nip
,b.Nip
,b.pass
,b.PositionCode
,b.number
FROM (
SELECT CASE
WHEN right(max(user_id), 8) IS NULL
THEN 'USR00000001'
ELSE ('USR-' + RIGHT('0000000' + cast(right(max(user_id), 7) + 1 AS NVARCHAR), 7))
END user_id
FROM dv_user_akun
) a
CROSS JOIN
(
SELECT
Nip
,'81dc9bdb52d04dc20036dbd8313ed055' pass
,PositionCode
,1 number
FROM Employee
WHERE Nip NOT IN (
SELECT Nik
FROM dv_user_akun
)
) b
