Unable to merge the data from two tables - postgresql

Question

I have two tables, the first one contain all the records and second table contains few records, i am trying to put left join to get all the records of first table and data columns of the records that matches in the second table.
Table A
id_step|id_workflow|id_action|
-------+-----------+---------+
1| 1| 11|
6| 1| 11|
7| 1| 11|
8| 1| 12|
9| 1| 12|
10| 1| 12|
Table B
id_step|id_client|id_process|id_workflow|is_approved|action_by|action_date|
-------+---------+----------+-----------+-----------+---------+-----------+
1| 10680| 10| 1|true | | |
I am looking to get the below result
Expected Output
id_step|id_client|id_workflow|id_action|is_approved|action_by|action_date|
-------+---------+---------- +---------+-----------+---------+-----------+
1| 10680| 1| 11|true | | |
6| 10680| 1| 11|pending | | |
7| 10680| 1| 11|pending | | |
8| 10680| 1| 11|pending | | |
9| 10680| 1| 11|pending | | |
10| 10680| 1| 11|pending | | |
I did try query
select
x.id_step,
y.id_client,
x.id_workflow,
x.id_action,
(case when y.is_approved is null then 'pending' else y.is_approved::text end ) as is_approved,
y.action_date,
y.action_by
from nw_adsys_wfx_config as x
left join nw_adsys_cli_wfx_process as y
on x.id_step = y.id_step
where x.id_workflow = 1
and y.id_process = 10
but i am getting this output
id_step|id_client|id_workflow|id_action|is_approved|action_date|action_by|
-------+---------+-----------+---------+-----------+-----------+---------+
1| 10680| 1| 11|true | | |

Answer 1

The query contains a left join but also a where condition on both tables which breaks the intend of the left join.
Instead, you can move the condition to the join
...
from nw_adsys_wfx_config as x
left join nw_adsys_cli_wfx_process as y
on x.id_step = y.id_step
AND y.id_process = 10
where x.id_workflow = 1
