When using longer model names eg. misCompanyContributor with column names the generated aliases for selected columns mix tableized modelname with colum name joined by two __, and sometimes the generated alias should exceed the allowed 30 characters long identifiers, and oracle complains with:</p> <p>{{<br/> ORA-00972: identifier is too long<br/> }}</p> <p>An example of large select with alias:<br/> {{<br/> SELECT<br/> ...<br/> mis_contributor.contributor_id AS mis_contributor__contributor_id<br/> ..<br/> FROM mis_contributor ...<br/> }}</p> Oracle DC-335
