SQL Joins Please help me the below - sql-server

Question

I have data In two tables like below:
I need the third table output. I have used joins but it is not working. I have used rank also.
SELECT
a.requestinstancelogid AS requestinstancelogidIn,
a.requestinstanceid AS InRequestInstance,
a.requeststatuscdid AS Inrequeststatuscdid,
a.Addnldocsin,
b.requestinstancelogid AS requestinstancelogidOut,
b.requestinstanceid AS OutRequestInstance,
b.requeststatuscdid AS Outrequeststatuscdid,
b.AddnldocsOut,
RANK() OVER (PARTITION BY a.requestinstanceid ORDER BY a.requestinstancelogid) AS one,
RANK() OVER (PARTITION BY b.requestinstanceid ORDER BY b.requestinstancelogid) AS two
INTO
#tmp_MultipleAddnlDocsLender
FROM
#tmp_addnldocsin a
LEFT JOIN
#tmp_addnldocsout b ON a.requestinstanceid = b.requestinstanceid
WHERE
a.requestinstanceid = 164944
This query returns 6 records.

Answer 1

The only way i can see that you could produce these results is the following:
;WITH Table1CTE AS
(
SELECT *,
ROW_NUMBER()OVER(PARTITION BY requestinstanceidin ORDER BY requestinstancelogid) AS rn
FROM Table1
), Table2CTE AS
(
SELECT *,
ROW_NUMBER()OVER(PARTITION BY requestinstanceidout ORDER BY requestinstancelogid) AS rn
FROM Table2
)
SELECT *
FROM Table1CTE T1
LEFT JOIN Table2CTE T2
ON T1.requestinstanceidin = T2.requestinstanceidout
AND T1.rn= T2.rn

Answer 2

As far as I can tell, the same column in both is the requestinstanceidout (could hardly read it, please post text or code next time)
Based on the idea of the above is correct, you could have something like this:
SELECT
*
FROM
table1 a
LEFT JOIN table 2 b
ON a.requestinstanceidin = b.requestinstanceidout
Hope this will help you!

I believe this is what you're looking for:
declare #request_instance_log_id_in table (
[log] [int]
, [in] [int]
, [status] [int]
, [created] [datetime] default current_timestamp);
insert into #request_instance_log_id_in
([log],[in],[status])
values (424593,164944,110),
(424594,164944,110),
(424595,164944,110);
declare #request_instance_log_id_out table (
[log] [int]
, [out] [int]
, [status] [int]
, [created] [datetime] default current_timestamp);
insert into #request_instance_log_id_out
([log],[out],[status])
values (424593,164944,112),
(424594,164944,112);
select [request_instance_log_id_in].[log] as [request_instance_log_id_in_log]
, [request_instance_log_id_in].[in] as [request_instance_log_id_in_in]
, [request_instance_log_id_in].[status] as [request_instance_log_id_in_status]
, [request_instance_log_id_in].[created] as [request_instance_log_id_in_created]
, [request_instance_log_id_out].[log] as [request_instance_log_id_out_log]
, [request_instance_log_id_out].[out] as [request_instance_log_id_out_out]
, [request_instance_log_id_out].[status] as [request_instance_log_id_out_status]
, [request_instance_log_id_out].[created] as [request_instance_log_id_out_created]
from #request_instance_log_id_in as [request_instance_log_id_in]
left join #request_instance_log_id_out as [request_instance_log_id_out]
on [request_instance_log_id_out].[log] = [request_instance_log_id_in].[log];
request_instance_log_id_in_log request_instance_log_id_in_in request_instance_log_id_in_status request_instance_log_id_in_created request_instance_log_id_out_log request_instance_log_id_out_out request_instance_log_id_out_status request_instance_log_id_out_created

424595 164944 110 2014-09-02 08:55:01.107 NULL NULL NULL NULL

I think you need a cross/outer apply
like this
SELECT
a.requestinstancelogid AS requestinstancelogidIn,
a.requestinstanceid AS InRequestInstance,
a.requeststatuscdid AS Inrequeststatuscdid,
a.Addnldocsin,
q.requestinstancelogid AS requestinstancelogidOut,
q.requestinstanceid AS OutRequestInstance,
q.requeststatuscdid AS Outrequeststatuscdid,
q.AddnldocsOut
FROM #tmp_addnldocsin a
OUTER APPLY (SELECT TOP 1
b.requestinstancelogid AS requestinstancelogidOut,
b.requestinstanceid AS OutRequestInstance,
b.requeststatuscdid AS Outrequeststatuscdid,
b.AddnldocsOut
FROM #tmp_addnldocsout b
WHERE a.requestinstanceidin = b.requestinstanceidout
ORDER BY AddnIdocsOut DESC) q
WHERE
a.requestinstanceid = 164944
