Issue manifests itself in this manner in sqlplus:

SQL> select index_name, index_type from user_indexes;

INDEX_NAME                     INDEX_TYPE
------------------------------ ---------------------------
PS_INST_SCHOOL_CDS             FUNCTION-BASED NORMAL
PS0INST_SCHOOL_CDS             FUNCTION-BASED NORMAL

select object_name, object_type from user_objects;


OBJECT_NAME          OBJECT_TYPE
-------------------- -------------------
PS0INST_SCHOOL_CDS   INDEX
PS_INST_SCHOOL_CDS   INDEX
PS_INST_SCHOOL_CDS   TABLE


 1  SELECT DISTINCT institution, aid_year, cps_school_code
 2  FROM ps_inst_school_cds WHERE institution = 'PSUNV' AND aid_year = '2004'
 3* ORDER BY institution, aid_year DESC, cps_school_code
SQL> /
SELECT DISTINCT institution, aid_year, cps_school_code

ERROR at line 1:

This issue does not result if the following is done:
- drop the desc syntax on the aid_year column in the order by clause
- drop the indexes on the table
