Unable to insert data into postgres table from a remote database connection - postgresql

Question

I am trying to insert data into a postgres table from a remote database table. I have written the following query for this purpose but I am getting following error.
'[Code: 0, SQL State: 42601] ERROR: syntax error at or near "table"
Position: 13 [Script position: 141 - 146]'
create table clintrial_EP_map.lead_sponsors (row_id SERIAL, lead_sponsors character varying)
insert into table clintrial_ep_map (lead_sponsors)
( select
*
from
dblink('dbname=x user=x host=x password=x port = x',
'
SELECT
distinct bm_dimt_clinical_trial.lead_sponsor
FROM
dwh_prod.bm_dimt_clinical_trial
where dataset_version_id = xx and lead_sponsor_class = ''xx''
'
) as ls (
lead_sponsor character varying
)
)
;
Please see, the following query is giving me desired output.
select
*
from
dblink('dbname=x user=x host=x password=x port = x',
'
SELECT
distinct bm_dimt_clinical_trial.lead_sponsor
FROM
dwh_prod.bm_dimt_clinical_trial
where dataset_version_id = xx and lead_sponsor_class = ''xx''
'
) as ls (
lead_sponsor character varying
)
;
I am not able to find a syntax error near 'table' in my insert query. Any suggestions here will be really helpful.
Thanks

Your query has two issues.
First: Create table is not ending with ; i am hoping that is typo and Second: Your insert statement is referring to schema name instead of schema qualified table name. And also using keyword 'table' in insert statment which is not required. So your correct query will be
create table clintrial_EP_map.lead_sponsors (row_id SERIAL, lead_sponsors character varying);
and
insert into clintrial_EP_map.lead_sponsors (lead_sponsors)
( select * from
dblink('dbname=x user=x host=x password=x port = x',
'SELECT
distinct bm_dimt_clinical_trial.lead_sponsor
FROM
dwh_prod.bm_dimt_clinical_trial
where dataset_version_id = xx and lead_sponsor_class = ''xx''
'
) as ls (lead_sponsor character varying)
);
