UPDATE statement

Question

I am trying to update on table from another where the Primary Key for both is trans_nbr.

My statement is posted below. All I am getting as an error is "a syntax error has occurred". The primary key is the only link between the two tables which also contain the same amount of rows.

I was able to do it before but then I found out the sequenceID on the brev_efile_user_doc_stats table is different depending on how the XML was handled in the review process which is why there is a corrected_seq_id column in the same table.

UPDATE 
    brev_efile_user_doc_stats.reviewed_event_code
    , brev_efile_user_doc_stats.corrected_seq_id 
SET 
    brev_efile_user_doc_stats.reviewed_event_code
    , brev_efile_user_doc_stats.corrected_seq_id = 
        (SELECT 
            brev_efile_review.reviewed_event_code
            , brev_efile_review.sequence_id 
        FROM 
            brev_efile_review 
        WHERE 
            brev_efile_review.trans_nbr = brev_efile_user_doc_stats.trans_nbr)

This is what you are looking for :

In SQL SERVER

UPDATE
    brev_efile_user_doc_stats
SET
    brev_efile_user_doc_stats.reviewed_event_code = R.reviewed_event_code
    , brev_efile_user_doc_stats.corrected_seq_id = R.sequence_id
FROM
    brev_efile_user_doc_stats S
    INNER JOIN brev_efile_review R
        ON R.trans_nbr = S.trans_nbr

In Mysql

UPDATE brev_efile_user_doc_stats AS S
    INNER JOIN brev_efile_review AS R ON R.trans_nbr = S.trans_nbr
SET S.reviewed_event_code = R.reviewed_event_code
    , S.corrected_seq_id = R.sequence_id
