Issues with join statement not displaying records - sql

Question

I'm trying to accomplish the following: Display all rows for Mgt.Dbo.Tab1 (157 rows) while joining 3 tables. The query only provides results for 76 rows from Mgt. i've tried using left join to no avail. HELP! TIA
Code:
select
mgt.UID
, Mgt.emp_num
, emp.EMP_NAME
, RTRIM(mgt.COMPANY)
, 'Company 1'
, jnl.d_w
, mgt.d_r
, jnl.UNITS
, jnl.RATE
, mgt.hours
, mgt.RATE
, rtrim(jnl.MEMO)
, mgt.UNIQUE_ID
, jnl.grow
, jnl.grow_num
, hdr.ch_date
, mgt.sub_by
, hdr.ch_num
from Mgt.dbo.sick as mgt
inner join Comp1.DBO.emp as emp
on Mgt.emp_num = emp.emp_num
inner join Comp1.dbo.hdr as hdr
on Mgt.emp_num = hdr.emp_num
inner join Comp1.dbo.jnl as jnl
on jnl.c_n = hdr.c_n
where COMPANY in ('Test')
and jnl.wg = 'SP'
and mgt.d_r = jnl.d_w
and mgt.d_r >= '8/20/2017'
and mgt.d_r <= '9/1/2017'
and mgt.d_r=jnl.d_w

Answer 1

After your edit, swap your inner joins for left joins and move any where clauses on left joined tables to the join condition:
select
mgt.UID
, mgt.emp_num
, emp.EMP_NAME
, RTRIM(mgt.COMPANY)
, 'Company 1'
, jnl.d_w
, mgt.d_r
, jnl.UNITS
, jnl.RATE
, mgt.hours
, mgt.RATE
, rtrim(jnl.MEMO)
, mgt.UNIQUE_ID
, jnl.grow
, jnl.grow_num
, hdr.ch_date
, mgt.sub_by
, hdr.ch_num
from Mgt.dbo.sick as mgt
left join Comp1.DBO.emp as emp
on Mgt.emp_num = emp.emp_num
left join Comp1.dbo.hdr as hdr
on Mgt.emp_num = hdr.emp_num
left join Comp1.dbo.jnl as jnl
on jnl.c_n = hdr.c_n
and jnl.wg = 'SP'
and jnl.d_w = mgt.d_r
where mgt.COMPANY in ('Test')
and mgt.d_r >= '8/20/2017'
and mgt.d_r <= '9/1/2017'

Answer 2

it appears the following did the trick:
select
mgt.UID
, mgt.emp_num
, emp.EMP_NAME
, RTRIM(mgt.COMPANY)
, 'Company 1'
, jnl.d_w
, mgt.d_r
, jnl.UNITS
, jnl.RATE
, mgt.hours
, mgt.RATE
, rtrim(jnl.MEMO)
, mgt.UNIQUE_ID
, jnl.grow
, jnl.grow_num
, hdr.ch_date
, mgt.sub_by
, hdr.ch_num
from Mgt.dbo.sick as mgt
left join Comp1.DBO.jnl as jnl
inner join comp1.dbo.hdr as hdr
on jnl.c_n= hdr.c_n
on jnl.d_w=mgt.d_r
and mgt.unique_id=jnl.memo
and hdr.emp_num=mgt.emp_num
where mgt.COMPANY in ('Test')
and mgt.d_r >= '8/20/2017'
and mgt.d_r <= '9/1/2017'
I was missing an inner join.
