Join to only the “latest” record with t-sql

Question

I\'ve got two tables. Table \"B\" has a one to many relationship with Table \"A\", which means that there will be many records in table \"B\" for one record in table \"A\".<

Answer 1

table B join is optional: it depends if there are other columns you want

SELECT
    *
FROM
    tableA A
    JOIN
    tableB B ON A.ID = B.TableAID
    JOIN
    (
    SELECT Max(RowDate) AS MaxRowDate, TableAID
    FROM tableB
    GROUP BY TableAID
    ) foo ON B.TableAID = foo.TableAID AND B.RowDate= foo.MaxRowDate
