Question

I have a table abc with a field datetime_abc type-> DATETIME in mysql.
and table xyz with a field datetime_xyz type-> DATETIME

I want a query which can separate the Date and Time.

select TIME(datetime_xyz) xyz_time_only, DATE(datetime_xyz) xyz_date_only from xyz where.....

This returns me a separate date and time.

Now What i need is

• select datetime_abc from abc where datetime_abc = xyz_date_only

Answer 1

If I’m not missing something you could try:

SELECT datetime_abc FROM abc
WHERE DATE(datetime_abc) = xyz_date_only

Or you could try

SELECT datetime_abc 
FROM abc INNER JOIN xyz
    ON DATE(abc.datetime_abc) = DATE(xyz.datetime_xyz)
