    Urgent. Last ms function change for SQL query

    Hi All,

    I am having big problems executing an easy access query in SQL. Last function as you may know is not working in SQl, so i need something equivalent. I need to get the last ship on a max date. Find the ms access that works below.



    Code:
    SELECT p.CREW_IPN, 
      p.LAST_NAME,
       p.FIRST_NAME,
        p.RANK_CODE,
    	 c.NATIONALITY, 
    	 ad.ADDRESS_NAME,
    	 	  last(ve.VESSEL_NAME) AS LastOfVESSEL_NAME, 
    	  Max(a.START_DATE) AS MaxOfSTART_DATE,
    	   p.EMAIL, a.START_STATUS
    FROM ((("dbo"."BASS_CREW_PROFILE" p INNER JOIN "dbo"."BASS_CREW_ACTIVITY" a ON p.CREW_ITEM_ID = a.CREW_ITEM_ID) 
    INNER JOIN dbo.BASS_VESSEL ve ON a.VESSELTRX_ID = ve.VESSELTRX_ID) 
    INNER JOIN "dbo"."BASS_REG_ADDRESS" ad ON p.MANNING_COMPANY = ad.ADDRESS_ID)
     INNER JOIN "dbo"."BASS_REG_COUNTRY" c ON p.NATIONALITY = c.COUNTRY_CODE
    GROUP BY p.CREW_IPN,
     p.LAST_NAME, 
     p.FIRST_NAME, 
     p.RANK_CODE, 
     c.NATIONALITY, 
     ad.ADDRESS_NAME, 
     p.EMAIL, 
     p.REC_DELETED, 
     a.START_STATUS,
     a.START_DATE
    HAVING (((p.EMAIL)<>'') AND ((p.REC_DELETED)<>-1) AND ((a.START_STATUS)='CONF') AND (a."START_DATE" > convert
           (datetime, '2020-01-01 00:00:00', 120))  and (a."START_DATE" < convert
           (datetime, '2021-01-01 00:00:00', 120)))
    ORDER BY p.LAST_NAME;
    I hope for some help.

    Thanks in advance.

    If Max(start_Date) identifies the latest record, why do you need last vessel? Shouldn't the record(s) associated with the latest start_date be the "last" vessel?

    I get duplicate records for some reason.

    Table 1
    Name Email
    1
    2
    3


    Table 2
    Name StartDate Vessel
    2 1/1/2020 X
    2 2/10/2020 Y


    Query above gives me both records. I want only the latest. And i need the vessel name so how can i get only the line with last date?
