i want select , don't want other data other table main table name of other tables

have tried following not working.

    select * project_content      left join project_master on project_master.id =  project_content.p_id     left join project_content_menu on project_content_menu.type_id =  project_content.p_c_id      left join project_menu_master on project_menu_master.id =  project_content.m_id        select * project_content      left join project_master on project_master.id =  project_content.p_id     left join project_content_menu on project_content_menu.type_id =  project_content.p_c_id      left join project_menu_master on project_menu_master.id =  project_content.m_id        select distinct(*) project_content      left outer join   project_master on project_master.id =  project_content.p_id     left outer join   project_content_menu on project_content_menu.type_id =  project_content.p_c_id      left outer join  project_menu_master on project_menu_master.id =  project_content.m_id       select * project_content ,project_master,project_content_menu,project_menu_master     project_master.id =  project_content.p_id , project_content_menu.type_id =  project_content.p_c_id , project_menu_master.id =  project_content.m_id       select pc.id id , pm.name pname , pmm.name menuname , pcm.name contentname , pc.name name          project_content pc,     project_master pm,     project_content_menu pcm,     project_menu_master pmm          pm.id = pc.p_id      ,      pcm.type_id = pc.m_id     ,      pmm.id = pc.p_c_id

if undesrtood correctly, want data main table, names instead of foreign keys other tables? if so, then:

select pc.id, pm.name, pcm.name, pmm.name, pc.name, pc.desc, pc.thumb, pc.src, pc.status project_content pc left join project_master pm on pm.id =  pc.p_id left join project_content_menu pcm on pcm.type_id = pc.p_c_id  left join project_menu_master pmm on pmm.id = pc.m_id
