DROP TABLE ptotracking;

CREATE TABLE ptotracking AS

SELECT M1.reelno, M1.frameno, M1.documentid, M2.last_update_date, M2.recorded_date

FROM ptoproperty_cleaned M1, ptoassignmentnd M2

WHERE (M1.reelno = M2.reelno) AND (M1.frameno = M2.frameno);

DROP TABLE ptotracking2;

CREATE TABLE ptotracking2 AS

SELECT M1.reelno, M1.frameno, M1.documentid, M2.name, M1.last_update_date, M1.recorded_date

FROM ptotracking M1, ptoassigneend M2
