内部加入mysql

Question

SELECT FirstName from tbl_User INNER JOIN tbl_Organisation  
on tbl_user.tbl_organisation_OrganisationID=tbl_Organisation.OrganisationID      
  WHERE tbl_organisation_OrganisationID = '23'

我想从tbl_Organisation获取一个列（OrgName）。我怎么能用上面的代码做到这一点。

Answer 1

只需：

SELECT tu.FirstName, tor.OrgName from tbl_User tu INNER JOIN tbl_Organisation tor
on tbl_user.tbl_organisation_OrganisationID=tbl_Organisation.OrganisationID      
WHERE tbl_organisation_OrganisationID = '23'

Answer 2

SELECT tbl_User.FirstName, tbl_Organisation.OrgName from tbl_User INNER JOIN tbl_Organisation  
on tbl_user.tbl_organisation_OrganisationID=tbl_Organisation.OrganisationID      
  WHERE tbl_organisation_OrganisationID = '23'

SELECT FirstName,tbl_organisation.OrgName
FROM tbl_User 
INNER JOIN tbl_Organisation ON tbl_user.tbl_organisation_OrganisationID=tbl_Organisation.OrganisationID  
WHERE tbl_organisation_OrganisationID = '23'

Answer 4
