Question

Can anyone help me understand this query? The mktpgmvhclxref.mktpgmvhclxrefId.mktgPgm part mostly. Generally it is table_name.columnName but here the format seems to be different

SELECT mktpgmvhclxref.mktpgmvhclxrefid.mktgpgm, 
       mktpgm.mktgpgm, 
       mktpgmvhclxref.cmpgn, 
       campaign.cmpgndescription, 
       mktpgmvhclxref.mktpgmvhclxrefid.vhcl, 
       vhclhierarchy.modname, 
       mktpgmvhclxref.mktpgmvhclxrefid.modyr, 
       mktpgmvhclxref.userinsrt, 
       mktpgmvhclxref.rowinsrt 
FROM   mktpgmvhclxref mktpgmvhclxref, 
       mktpgm mktpgm, 
       vhclhierarchy vhclHierarchy, 
       campaign campaign 
WHERE  mktpgmvhclxref.mktpgmvhclxrefid.mktgpgm = mktpgm.idmktgpgm 
       AND mktpgmvhclxref.cmpgn = campaign.campaignid 
       AND mktpgmvhclxref.mktpgmvhclxrefid.vhcl = vhclhierarchy.vhcl
