Date and Time
Hello, I'm doing an insert into with date and time type fields. I was reading: http://dev.mysql.com/doc/refman/5.1/en/date-and-time-literals.html My question is: is the format always 'year month day'?.. or can we save dates in 'month day year' as well?

In DATE, DATETIME, and TIMESTAMP columns, you must specify the date part on year-month-day order. If you want to store a value in a different format, you must use some other data type such as VARCHAR. But then it won't be interpreted as a date. If you want to display a date from a DATE, etc. column in some other format, pass the value to DATE_FORMAT(). http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_date-format If you want to reformat a date value in some other format to put it in year-month-day format so that you can store it in a DATE, etc. column, STR_TO_DATE() might be helpful. http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_str-to-date STR_TO_DATE() can be useful, for example, when loading non year-month-day data into a table with LOAD DATA. You can use STR_TO_DATE() to reformat the values on the fly.

Re: find date an time of a table update
Hi, mysql show table status like 'tablename'\G will report you the date and time of creation, updation,etc of the specified table. 'SHOW STATUS' enables only view. Note 1: For some storage engines, this value is NULL. For example, InnoDB stores multiple tables in its tablespace and the data file timestamp does not apply. As you have specified that you want it to display it in the webpage, then retrieve the same from the 'tables' table of information_schema database. mysql use information_schema; mysql show tables; mysql select * from TABLES where TABLE_NAME='tablename'; Note 2: Check the user privilege to access the database.

Re: Migrating Access Tables -- Empty Columns, Date and Time
Bob My versions are Access 2000 and MySQL 4.0.20. Here's what I do. When exporting my Access table, I choose the file type Text Files. Then, on the next dialog box, make sure to click the Advanced button to get to the formatting information. Change the date order to YMD and the date delimiter to -. That will take care of the date. As for the NULL value. The table into which I'm importing has columns defined to allow NULLs, but when I import the Access table with empty columns, like you describe, it doesn't force a null -- it just leaves the value blank. It doesn't cause any problems, but if you want to force a NULL then I guess you could rework the exported file to state NULL for the empty fields you want to read as such.

Re: date and time
Hi, can someone explain me the avantage of using date and time, and also can i set time + XX minutes?? Thanx Anthony Short answer is: You can use the date and time functions and formats. There is one or just use '+' or '-' See chapter 6 in the ref. manual. If you need both date and time use the datetime field type since you will simplify sorting and conditionals. William R.

Re: Date Field + Time Field = Datetime Field?
Alex, Further to Anvar's suggestions: - in addition to time_to_sec() recommend you look at sec_to_time() - which saves the repeated division to produce 'elapsed time' - alternatively take a look at unix_timestamp() and from_unixtime() which would allow the recording of all times to the second/as seconds, and convert to time/date presentation formats as required - regardless, unless you want large values expressed as hours (even beyond 24 hours) all elapsed time calculations must be divided by 86400 so that the integral part can be passed into a 'date' function, and the remainder into a 'time' function Times/dates can be stored ready for calculation or ready for display - it is always easier to convert a calculated field for display, than to perform arithmetic on a formatted-for-display field!

Hi Alex, I don't think your problem will solved by making the time columns to full datetime columns as there is no functions to subtract two datetime values directly. But you can can keep the time columns and go on like this: convert the time into seconds using time_to_sec function. subtract fromtime from totime. this will yield the difference in seconds now you can take the elapsed time in hours,minutes or seconds. The sql might be something like: Select (time_to_sec(totime) - time_to_sec(fromtime)) / 60 / 60 as hours from table. Section 7.4.11 of the manual explains date and time functions.

I thought at first that UPDATE time_worked SET dtstart = concat(datework, start); would work, but that gave me a syntax error. I can't seem to find anything in the manual that would help, either. Is there any way to do this without going through and manually updating? I'd really appreciate any hints you could give. FYI, I'm running MySQL 3.23.37.

Re: Date Field + Time Field = Datetime Field?
Hi Alex, I don't think your problem will solved by making the time columns to full datetime columns as there is no functions to subtract two datetime values directly. But you can can keep the time columns and go on like this: convert the time into seconds using time_to_sec function. subtract fromtime from totime. this will yield the difference in seconds now you can take the elapsed time in hours,minutes or seconds. The sql might be something like: Select (time_to_sec(totime) - time_to_sec(fromtime)) / 60 / 60 as hours from table. Section 7.4.11 of the manual explains date and time functions. Anvar At 06:00 PM 10/01/2002 +, you wrote: I've been working with a timesheet database, where all the employees of my small business enter in the hours they work on projects. I've been storing, for each record, a date of work, a start time, and a finish time. When I attempted to write a Perl script to display invoices, though, I ran into the issue that subtracting one time from another yields inconsistent results. Thus, I'm going to convert to datetime fields, which would store just the start and finish times as datetime. I'd like to automate the switchover, so I don't have to go through and maually update.
