O distinct nao funciona juntamente com Inner Join?
SELECT distinct bug.* FROM .bug
INNER JOIN link ON bug.bg_bug_id = link.ln_bug_id
INNER JOIN test ON link.ln_entity_id = test.ts_test_id
WHERE test.ts_user_01 = 32552
Do jeito que esta, ela retorna um erro:
ORA-00932 inconsistent datatypes: expected - got CLOB
