Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-244
    Summary: Hibernate creates alias identifiers that are too long
       Type: Bug

     Status: Unassigned
   Priority: Blocker

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.2

   Assignee: 
   Reporter: Mark Woon

    Created: Mon, 11 Aug 2003 1:17 AM
    Updated: Mon, 11 Aug 2003 1:17 AM
Environment: Oracle 9.0.2.

Description:
After switching to Hibernate 2 I find that Hibernate is still creating alias identifiers that are too long.

The HQL query that's causing it:
select freqInSs, freqInRae, freqInSs.allele
from DbVariantPosition as varPos,
DbVariantAllele as varAl,
DbAlleleFrequencyInSampleSet as freqInSs,
DbAlleleFrequencyInRaceAndEthnicity as freqInRae
where varPos.goldenPathPosition = ?
and varPos.id != ?
order by freqInSs, freqInRae

The SQL query that gets generated:
select dballele2_.alleleFreqInSampleSetsId as alleleFreqInSampleSetsId0_, dballele3_.alleleFreqInSSRaceEthnicityId as alleleFreqInSSRaceEthnicityId1_, dballele2_.variantPositionId as variantP2_0_, dballele2_.sampleSetId as sampleSe3_0_, dballele2_.allele as allele0_, dballele2_.totalObserved as totalObs5_0_, dballele2_.frequency as frequency0_, dballele3_.alleleFreqInSampleSetId as alleleFr2_1_, dballele3_.racialClassId as racialCl3_1_, dballele3_.ethnicClassId as ethnicCl4_1_, dballele3_.totalObserved as totalObs5_1_, dballele3_.frequency as frequency1_, dballele2_.alleleFreqInSampleSetsId as x0_0_, dballele3_.alleleFreqInSSRaceEthnicityId as x1_0_, dballele2_.allele as x2_0_ from VariantPositions dbvarian0_, VariantAlleles dbvarian1_, AlleleFreqInSampleSets dballele2_, AlleleFreqInSSRaceEthnicity dballele3_ where (dbvarian0_.goldenPathPosition=? )and(dbvarian0_.variantPositionId!=? ) order by  dballele2_.alleleFreqInSampleSetsId , dballele3_.alleleFreqInSSRaceEthnicityId


The offending alias identifier is "alleleFreqInSSRaceEthnicityId1_" which is 31 characters long -- one more that Oracle's max identifier length.

Is this a known problem?  I can attach my mappings if it will help...
