How To Get Just Date To Display In Field When Using TIMESTAMP?
I would like to capture the date and time in a field for each record. I know that using TIMESTAMP and default value of CURRENT_TIMESTAMP returns the full date and time but I only want the date displayed in my webpage table when displaying the records. Should I be using something else other than TIMESTAMP or is there some parameters I can use to do this?

Select Today And Yesterday
I know that I can use DATE_SUB(NOW(),INTERVAL n DAY) and compare that to a datetime field to get the items from the last n days. What I would like to do is write a query that selects all the rows whose timestamp matches today and all of yesterday, not just the last 24 or 48 hours. That is, if it is 2pm, I want all of the items from 2pm back until midnight of that day and then the 24 hours before that as well.

Date Vs Timestamp
I have a somewhat large table (about 900,000 rows). I regularly need to run many queries against this table and it's is rather slow. Before making any major changes, I wanted to confirm whether the following changes would help. Right now, I run a query like this: SELECT count(*) FROM refer WHERE date >= '$date1' AND date <= '$date2' However, "date" is actually of type timestamp. So I have an index on the field, but it has the same cardinality as the number of rows, as you might expect. I've also heard using a reserved word of 'date' can be a problem, but not sure if that's a performance issue. I think I may occasionally still need this level of granularity for some things, but 99% of the time, I really only need the actual date for my SELECT statements. I'm thinking it might be best to create a field2 that is of type date and use that for the queries, with an index, and drop the index on field1 altogether. The more I think about the more I'm convinced the way I'm doing it now is the reason it is so slow. Can someone please confirm my stupidity?

Timestamp :: Registration Date
As a newbie to MySQL and PHP, I have been able to set up MySQL as test server on my MacOS X and have also succeeded in connecting my test sites registration form to the proper table in MySQL. Everything works fine except getting MySQL to insert the registration date/time automatically as a new record is posted. I have created two "Timestamp"-date columns - the first one for "Change date" and the second for "Registration date". According to what I can gather from reading, this should do the trick, but it doesn't. No date or time is inserted in the registration date field. Can someone explain (in newbie terms) what I am doing wrong and what I should do to make it work? I want the registration date to be filled-in automatically in every new record and then stay unchanged even if other parts of the record are changed.

DATE / TIMESTAMP Default Values
im is having problems with auto inserting date in my table. I dont know what is the default value i will set if column type to DATE. It was succesful though if is use the TIMESTAMP type in the column and is using CURRENT_TIMESTAMP as the dafault value. mysql automatically inserts the current date and time to the database everytime a new record is inserted. The problem with using TIMESTAMP is that i only want the date and not the additional time. Is there a default value I can use for the DATE function instead of using TIMESTAMP? I already tried NOW(), CURDATE(), CURRENT_DATE() to no avail

TIMESTAMP :: Creation And Update Date
I want to create an auto creation date and update date in my mysql table. I am using the "MySQL Cookbook" approach, using the TIMESTAMP field which basically is: - create 2 new fields in the table (t_create and t_update) - both NULL - when a new record is created they both will register a common timestamp - when the record is modified the t_update will change, but not the t_create

Timestamp From Any Field
Is it possible to get a timestamp from a table that doesn't have any timestamp field? In other words, I've got a table with three columns, none of which are a date, or timestamp type column. Only varchars (that don't contain any time/date type data). Is there a SQL statement that will return the time each record or row was entered into the table?

TIMESTAMP As Primary Key Field?
If I need a primary key (PK) that can contain the numbers as large as an INT, I would normally use an INT. But the problem with INT is that, if the keys are all used up (exhausted), I need to start thinking of ways to reuse “skipped” or “deleted” primary keys. In other words, I need to fill up the “gaps” so as not to waste them. Another problem is that, if the PKs are all used up, I need to have another timestamp field in the same table to tell me which very old record I can delete to make space for the new record that I want to insert. (Assuming that we can delete very old records. Eg a web email account where, say, an account which stayed dormant for 5 years.) Since INT has these problems, and since both INT and TIMESTAMP datatypes have a size of 4 bytes, I was thinking, why not just use TIMESTAMP for my PK field instead. Besides TIMESTAMP is just an integer internally in MySQL, representing the number of seconds since epoch (1970-1-1 00:00:00). It would be as index-able as an INT? Searching through it will be just as efficient? Using it as foreign keys in multiple tables would give no problem? Is using TIMESTAMP as a PK field OK ?

TIMESTAMP Field Automatically Set
I want to add a timestamp field to my table so that it is set automatically when a new record is added. I don't want it updated. I tried to follow the manual instructions but I can't get it to work. 1) I added a field called "EntryTime" to my existing table. Its the only timestamp type field. 2) I tested an insert with a NULL set for the column. This didn't work. 3) I added CURRENT_TIMESTAMP as the default value to the field. I tested the insert, and this didn't work. I even tried renaming the field to TIMESTAMP and didn't work as well. Whats the skinny to get this to work?

Find Closest Row By Timestamp Field
Firstly, if the majority of queries to my sql dbase are done via my TIMESTAMP field, should that be my primary key? How can I find the row with a TIMESTAMP value closest to a given timestamp? And is this a bad way to do this? Each table holds a row for each minute in a year (1440 * 365 = many rows) so that could cause quite a performance hit.

Getting Year, Month, Day From A Timestamp Field.
I'm currently programming my own blog, however I've come into a minor problem with the way I want to display my archived posts. I want to display a list by year (2006, 2005, etc.) then a list of months for the specified year (nov, dec, etc.). I've searched the documentation and have been unable to find a sql command that retrieves parts of a timestamp. ie; timestamps are in YYYYMMDDHHMMSS format. I'm looking to extract the year, or month from that. ie; SELECT YEAR(timestamp) AS y FROM blog_posts GROUP BY y ORDER BY y DESC. or replace YEAR() with MONTH(). You get the idea. I did find a YEAR() command in the documention but it doesn't look to be what I'm looking for, since I was unable to find it's system commands MONTH() and DAY().
