Gets a unique and length compliant alias, based on a proposed alias name. If the proposed name is unique and of legal length, it will be returned. If the name is not unique, a suffix is generated with an underscore and integer. Integers are incremented until a unique name is found, e.g. EMPNO_2. The unique alias will be added into given aliasSet implicitly.

Parameters:

proposedName - name to use or add a suffix to.

maxLength - technology dependent length. ITechnology.getMaxTableNameLength() may be used.

aliasSet - aliases used in the current query, used to check uniqueness of proposedName

Returns:

unique alias

Throws:

oracle.odi.domain.mapping.exception.MappingException

oracle.odi.domain.adapter.AdapterException
