Linking same table together syntax problem

Question

Hi All
I've never had to link a table to itself before, but as I try and do it now I keep getting "missing keyword" error message at the point I try and assign a different name to the second instance of my table. Can anyone point out my mistake please?
Here is the SQL:
SELECT FSA_CO, FSA_NO, FSA_ADESC, FSA_MFNO, FSA_SREF, ERE_RET.ERE_BELONGS_TO, ERE_RET_1.ERE_DESC
FROM (FSA_ACC LEFT JOIN ERE_RET ON FSA_ACC.FSA_HIRE_GRP = ERE_RET.ERE_ID) LEFT JOIN ERE_RET AS ERE_RET_1
ON ERE_RET.ERE_BELONGS_TO = ERE_RET_1.ERE_ID WHERE (((FSA_ACC.FSA_CO)='01') AND ((FSA_ACC.FSA_NO)='P008'))
Many thanks in advance
Chris

Well, the regular Oracle syntax would be
SELECT fsa_co,
       fsa_no,
       fsa_adesc,
       fsa_mfno,
       fsa_sref,
       a.ere_belongs_to,
       a1.ere_desc
  FROM fsa_acc, ere_ret a, ere_ret a1
WHERE fsa_acc.fsa_hire_grp = a.ere_id
   AND a.ere_belongs_to = a1.ere_id
   AND fsa_acc.fsa_co = '01'
   AND fsa_acc.fsa_no = 'P008'I think the AS is what it's complaining about - it didn't care for it in regular syntax.
