Hello Edson!

No, you do not - TIBO_Query does not exist, it could be TÌBOQuery or
TIB_Query.

Strange, your query seems OK. Are you certain that it is this query
it complains about? Anyway, just try changing to explicit join and
see if that make any difference:

SELECT CO.CD
, CO.NOME
, EU.EMPRUSU_ID
, EU.CORR_ID
FROM EMPR_USU EU
JOIN CORR CO
ON CO.CORR_ID = EU.CORR_ID
WHERE CO.CD = :CD
AND EXISTS ( SELECT 1
FROM PJ
WHERE PJ.CORR_ID = CO.CORR_ID )

If this does not help, try to check your properties to see if you
reference a field that can be ambiguous, because this query is simple
and should work.

HTH,
