Ambigious Column Not Detected In SELECT with JOIN

Question

I wrote the following SELECT query.
SELECT TRANS.ID, TRANS.INVISIBLE
FROM TRANS
JOIN TRANSCAT TC ON TC.ID = TRANS.TRANSCATID
JOIN TRANSTYPE TT ON TT.ID = TRANS.TRANSTYPEID
WHERE INVISIBLE = 0
AND ID IN (SELECT DISTINCT TRANSID FROM XTRANS WHERE XTRANS.DESCR LIKE '%Geri%' )
The four table are as follows.
CREATE TABLE "DBO"."TRANSCAT"
(     "ID" NUMBER(19,0) NOT NULL ENABLE,
     "NAME" VARCHAR2(16 CHAR),
     CONSTRAINT "pTransCat" PRIMARY KEY ("ID") ENABLE NOVALIDATE
CREATE TABLE "DBO"."TRANSTYPE"
(     "ID" NUMBER(19,0) NOT NULL ENABLE,
     "NAME" VARCHAR2(16 CHAR),
     "MESSAGE" NUMBER(1,0) NOT NULL ENABLE,
     CONSTRAINT "pTransType" PRIMARY KEY ("ID") ENABLE NOVALIDATE
CREATE TABLE "DBO"."TRANS"
(     "ID" NUMBER(19,0) NOT NULL ENABLE,
     "REFERENCE" NUMBER(10,0) NOT NULL ENABLE,
     "TRANSCATID" NUMBER(19,0) NOT NULL ENABLE,
     "NAME" VARCHAR2(48 CHAR),
     "TRANSTYPEID" NUMBER(19,0) NOT NULL ENABLE,
     "SIZE" VARCHAR2(8 CHAR),
     "KEYWORD" VARCHAR2(64 CHAR),
     "PARAMCOUNT" NUMBER(3,0) NOT NULL ENABLE,
     "PARAMHELP" CLOB,
     "INVISIBLE" NUMBER(1,0) NOT NULL ENABLE,
     "SELECTFLAG" NUMBER(1,0) NOT NULL ENABLE,
     "STAMP" NUMBER(5,0) NOT NULL ENABLE,
     CONSTRAINT "pTrans" PRIMARY KEY ("ID") ENABLE NOVALIDATE,
     CONSTRAINT "fTrans_TransCatId" FOREIGN KEY ("TRANSCATID")
     REFERENCES "DBO"."TRANSCAT" ("ID") ENABLE,
     CONSTRAINT "fTrans_TransTypeId" FOREIGN KEY ("TRANSTYPEID")
     REFERENCES "DBO"."TRANSTYPE" ("ID") ENABLE
CREATE TABLE "DBO"."XTRANS"
(     "ID" NUMBER(19,0) NOT NULL ENABLE,
     "TRANSID" NUMBER(19,0) NOT NULL ENABLE,
     "LANGUAGEID" NUMBER(19,0) NOT NULL ENABLE,
     "DESCR" CLOB,
     "REMARK" CLOB,
     "HELP" CLOB,
     "STAMP" NUMBER(5,0) NOT NULL ENABLE,
     CONSTRAINT "pXTrans" PRIMARY KEY ("ID") ENABLE NOVALIDATE,
     CONSTRAINT "uXTrans_TransId_LanguageId" UNIQUE ("TRANSID", "LANGUAGEID") ENABLE,
     CONSTRAINT "fXTrans_LanguageId" FOREIGN KEY ("LANGUAGEID")
     REFERENCES "DBO"."LANGUAGE" ("ID") ENABLE,
     CONSTRAINT "fXTrans_TransId" FOREIGN KEY ("TRANSID")
     REFERENCES "DBO"."TRANS" ("ID") ENABLE
CREATE UNIQUE INDEX "DBO"."uXTrans_TransId_LanguageId" ON "DBO"."XTRANS" ("TRANSID", "LANGUAGEID") ;
As you can see every table has an ID column as primary key. When I run this query in SQLDeveloper, the result was zero rows. In the detail plan, Oracle seems to match TransId column of XTrans with TransType's Id column.
I am new to Oracle. In Sql Server 2005 i get an ambigious column error. Why doesn't Oracle give such an error? Is this a bug?

Answer 1

My intention is to match XTRANS.TRANSID with TRANS.ID not TRANSTYPE.ID. But oracle matches it with TRANSTYPE.ID. Also TRANSTYPE is not in the FROM clause, why is it the default table? I couldn't understand.
As you said, I get the expected error with following SELECT
SELECT TRANS.ID, TRANS.INVISIBLE
FROM TRANS, TRANSCAT TC, TRANSTYPE TT
WHERE INVISIBLE = 0
AND TC.ID = TRANS.TRANSCATID
AND TT.ID = TRANS.TRANSTYPEID
AND ID IN (SELECT DISTINCT TRANSID FROM XTRANS WHERE XTRANS.DESCR LIKE '%Geri%' )
