Re: Help with inner/outer join - Mailing list pgsql-general

Help with inner/outer joinIt looks like you're trying to join against a
table ebs_environment_t that I didn't see in the FROM list, so that might
affect things? But anyway, the outer join syntax should look something like
this:

SELECT
ebs_webserver_t.server_instance_nme,
ebs_webserver_t.install_directory,
ebs_webserver_t.docs_directory_nme,
ebs_webserver_t.other_info,
ebs_webserver_t.port_num,
ebs_webserver_t.host_nme,
ebs_webserver_t.ip_num,
ebs_webserver_t.cert_expiration,
ebs_webserver_t.dns_nme,
ebs_webserver_t.url_nme,
ebs_cert_type_t.cert_nme,
ebs_domain_t.domain_nme,
ebs_node_t.node_nme,
ebs_sbu_t.sbu_nme,
ebs_servertypes_t.server_type_nme
FROM
ebs_webserver_t
LEFT JOIN ebs_cert_type_t ON ebs_webserver_t.cert_type_id =
ebs_cert_type_t.cert_id,
LEFT JOIN ebs_domain_t ON ebs_webserver_t.domain_id =
ebs_domain_t.domain_id,
LEFT JOIN ebs_node_t ON ebs_webserver_t.node_id = ebs_node_t.node_id,
LEFT JOIN ebs_sbu_t ON ebs_webserver_t.sbu_id = ebs_sbu_t.sbu_id,
LEFT JOIN ebs_servertypes_t ON ebs_webserver_t.server_type_id =
ebs_servertypes_t.server_type_id
WHERE  ebs_webserver_t.environment_id      =
ebs_environment_t.environment_id

Subject: [GENERAL] Help with inner/outer join


I'm not sure if somebody would be able to help me with this, but I'm stuck.
I've read the SELECT documentation on this but still can't seem to get it to
work.
I have a 226 rows in a table called ebs_webserver_t.  I run this query that
makes a SELECT and JOINs together 6 tables.  When I run the query, it only
returns 144 web servers. So I need to do a inner  or outer join I guess on
the ebs_webserver_t.  Would anybody be able to help me with the syntax?


Here's the SQL Statement that brings back on 144 rows:


SELECT
ebs_webserver_t.server_instance_nme,
ebs_webserver_t.install_directory,
ebs_webserver_t.docs_directory_nme,
ebs_webserver_t.other_info,
ebs_webserver_t.port_num,
ebs_webserver_t.host_nme,
ebs_webserver_t.ip_num,
ebs_webserver_t.cert_expiration,
ebs_webserver_t.dns_nme,
ebs_webserver_t.url_nme,
ebs_cert_type_t.cert_nme,
ebs_domain_t.domain_nme,
ebs_node_t.node_nme,
ebs_sbu_t.sbu_nme,
ebs_servertypes_t.server_type_nme
FROM
ebs_webserver_t,
ebs_cert_type_t,
ebs_domain_t,
ebs_node_t,
ebs_sbu_t,
ebs_servertypes_t
WHERE ebs_webserver_t.cert_type_id       = ebs_cert_type_t.cert_id
AND   ebs_webserver_t.domain_id             = ebs_domain_t.domain_id
AND   ebs_webserver_t.node_id                 = ebs_node_t.node_id
AND   ebs_webserver_t.environment_id      = ebs_environment_t.environment_id
AND   ebs_webserver_t.sbu_id                   = ebs_sbu_t.sbu_id
AND   ebs_webserver_t.server_type_id       =
ebs_servertypes_t.server_type_id



Thank you for any help you could give me!
