Question

There is a column (REC_CREATE_TIMESTAMP) in a table which shows date in format YY-MM-DD. I would like select the latest (by time) of a certain date (let’s say Aug 31, 2011). The first column should be the timestamp in hh24:mm:ss and the rest should be all columns (*) of this table. How do I do it?

Using Oracle 2.1.1.64

REC_CREATE_TIMESTAMP – NOT NULL – DATE

Answer 1

SELECT * FROM Table WHERE REC_CREATE_TIMESTAMP IN
(  
    SELECT
       MAX(REC_CREATE_TIMESTAMP) as REC_CREATE_TIMESTAMP
    FROM
       Table
    WHERE
       TO_CHAR(REC_CREATE_TIMESTAMP, 'YYYYMMDD') = '20110831'
)
