Can someone please assist me with the following problem. I am using Carbon to get the current time. Once I got the time and send it to my (myphpadmin) database it displays the whole date and time and not just the time. Here are all the code being used.
Laravel Code:
$date = Carbon::parse(now())->timezone('GMT+2');
$time = $date->toTimeString();
$UserRequest->finished_at = $time;
SQL Database layout and format:
Display: (Incorrect)
I have literally tried all the custom formatting from Carbon docs nothing sends over just the time.
I need this format -> 12:09 pm
Table Structure:
The problem more complicated than you describe.
First looks as finished_at is datetime field, so you can not store only date in this field. Sure, you can change the column format to time and store only time part. But this approach can cause problem with overdate date (started_at may be previous day or early).
So I think you need not change your storing flow, but you can change representation flow by using appropriate format

Ok this should be a relatively easy thing to do, yet I'm at the head desk stage trying to figure out the insanity here.
I have a table called tblPersonnel. I'm tracking two document expiration dates in date/time fields called CED and PPED. When I run a query against tblPersonnel I need it to look at PPED, determine if that document is expired and if so use CED instead. I have a few fields in the query that need to use this concept to determine what the output value is, but I am hitting a wall here trying to get the query to spit out the correct value. Here's what I'm using for one of the fields - Document Expiration Date: IIf([PPED]-Now()<0,[CED],[PPED]). What's happening is that the expression is constantly popping as false, so PPED is getting used regardless if it's an expired date or not. Does anyone have any ideas as to what I'm doing wrong here?
I've also tried to set this up as its own field in tblPersonnel, but that's even more aggravating. If I try to set the field to just a text field - IIf([PPED]-Now()<0,"Yes","No"), the formula will accept the use of Now(), but it doesn't like the reference to the other fields in the table. If I set it as a calcuated column, I can reference the other fields but it doesn't like Now(). I'm at a loss here.
If PPED is less than Date(), it is expired. Don't need to subtract. Assuming CED and PPED are just date parts, no time, consider:
IIf([PPED] < Date(), [CED], [PPED])
If PPED could be null:
IIf(Nz([PPED],0) < Date(), [CED], [PPED])
Ok finally fixed it here. I had another issue in that I wasn't accounting for how Access would handle a Null or blank value in PPED. The functioning formula is Document Expiration Date: IIf(Len([PPED])>0,IIf([PPED]<Date(),[CED],[PPED]),[CED]) Thanks to June7 for helping me simplify the expression, as I was using DateDiff('d',[PPED],Date())<0 but their answer is just so much cleaner and quicker to type.
I'm trying to setup a query that will show me all of the records in a particular table where the listed expiry date is either in the past or upcoming in the next 6 months (approximately).
At the moment, I have the "Expiry" field added to my query and the 'Criteria' as .
When I try to save the query, I get the following message:
Access can't evaluate an expression or convert data because data types aren't compatible with each other.

I've tried searching the web for a solution, but most websites refer to the Date() function that doesn't seem to be available in the Access 2016 Custom Web App. When I take out the "+180", it works fine but obviously doesn't give me what I need.
Any help would be appreciated.
=============================
UPDATE:
Some users have asked for my SQL and Table Design details. I don't seem to have any way of accessing the SQL View (the option doesn't appear), but here's a copy of my table view:
Access Query Table Design
In the table, 'Active' is a Yes/No field and 'Expiry' is Date/Time.
Try
< DateAdd(Day, 180, Today())
as criteria.
According to https://msdn.microsoft.com/en-us/library/office/jj249452.aspx this should work in a custom web app.
Error says that you have two different date types and they can't be compared. so, as the Today() returns only the Date with 12:00 pm, I can guess that your other "Expiry" Field is a datetime type. So, you can do either: use Format function to convert datetime to date like this
Format([2/22/2012 12:00 PM],"dd/mm/yyyy")
or use Now() function which returns datetime,
or Share your Code :)
I would like to ask how to add datetime ('Y-m-d h:i:s') format field for the SQL.
The name of my table is groups, the name of the field is date_add
i am using cake PHP 3, i want to use the timezone Australia/Perth but i don't know how to begin.
I successfully displayed added my date using
$group->date_add = date("Y-m-d h:i:s");
However, the result for the time is not correct with the timezone.
Datetime in PHP in general
Per the documentation of DateTime you can use all options available for the date() functions for formatting. Your main mistake in the formatting is the difference betweetn a y and a Y being the difference between a year in two and a year in four numbers.
Secondly you say you want to add the correct time zone. This is a bit odd however since you always want to add the same time zone. If you want to convey the fact that all your dates are Australia/Perth as information why do you not simply add that text after it?
If you mean this is a problem since you store the information in a different time zone to begin with and thus have a conversion problem you can set the correct time zone on the DateTime object itself. But you need to be sure the DateTime object is constructed with the correct original time zone to begin with. Observe the following code for an explanation:
<?php
$DateTime = new DateTime(); // This is now Europe/Amsterdam for my laptop
var_dump($DateTime->format('dmY h:i e'));
// result of var_dump is: string(31) "13102015 12:00 Europe/Amsterdam"
$DateTime->setTimeZone(new DateTimeZone('Europe/London'));
var_dump($DateTime->format('dmY h:i e'));
// result of var_dump is: string(28) "13102015 11:00 Europe/London"
Take aways:
e is the format modifier for the time zone
Conversion of time zones is possible with PHP's DateTime object. Find out what your default time zone is on your current PHP installation to see if you need to convert or not. See information on the date.timezone setting here: http://php.net/manual/en/datetime.configuration.php
Cake 3.0 specific
As Oops D'oh pointed out in the comments there are a lot of CakePHP specific things to know as well. Since he added an excellent part concerning that I suggest you read that as well.
This is specifically for MS-Access Web Databases (requires Sharepoint hosting) which has many limitations compared to their client counterparts, like no VBA, instead you get form macros and data macros to manage data.
I've run into a weird bug on one of my applications. I have a query used to check stock levels against a "minimum stock level" also saved in the table. The query is pretty intense and there are over 4,000 records now to check against. These querys normally take about 75s. So I have made a little label that gets updated every time the form is loaded showing the time and date the query was last run, and the duration in seconds it took. (so users can see how fresh the data is and decide if it needs to be run again)
Now, the weird thing is it works fine in my Access client, but when I sync my changes to the server and try it in a web browser I get a "type mismatch" error. A small table is used to store the start and end times whenever the query is run, that's how I get the timestamp data. These fields are in a "Date/Time" format, obviously. But it seems the problem here is changing the date format to a string format so it can be put in a label on the form. The Access client seems perfectly capable of doing this, while the web client stumbles and falls.
My problem is, how do I change data in a date/time format to a string format in a Web database? I can't figure out how to do this. The tools are so limited. I may have to end up answering my own question here but I'm posting this for others just in case.
To return a value from a data macro as string, you have to format the internal date/time format as a string. In Access an internal date/time value is a double number with the integer part as number of days since 1900, and the “decimal” time part is a fraction of 24 hours. Unfortunately if you simply wrap the date/time in the str$() function we had for 20+ years, then you get something JUST like if you type this into the debug window:
? cdbl(now())
41955.5478587963
The solution is to simply pull out each part. And “nice” is while in few cases a data macro will cast the data type, it does in this case and thus the STR$() command is not required.
The expression you thus can use is this:
Month([d]) & "/" & Day([d]) & " Time = " & Hour([d]) & ":" & Minute([d])
So say to pluck out the VERY LAST start time column from say a invoice table, since we don’t have a dmax(), then we simply sort the table in the order we want and pull out the first row.
Our data macro will thus look like:
Note how in above I simply typed in the SQL and SET the order on the date/time column. I want the MOST recent invoice start date and time. For those new to SQL, then I suggest you build a query in the query builder and specify a query in above lookup feature, since many are not "comfortable" typing in free hand SQL as I did above.
Now, in your browser side (UI) macro, you can use this code:
The above returns a formatted string that you can stuff into a text box, or as per above code change the caption of a label.
Unfortunately with silly problems like this, it becomes a path-of-least resistance thing.
Since my intended result was simply to get "a timedatestamp from a table to show up on a form (so users could see when a query was last run)", this became redesigning my form in Access to be a text field instead of a label. Text fields can be adjusted to accept "Time/Date" formats, so this is exactly what I did, it now pulls the timestamp data directly from the last record of the table and requires no extra formatting to appear in the web browser. I redesigned the text field to appear and function more like a label, and my desired function was achieved.
However, since my question specifically asks, "how do you change a time/date format into a string format in a Web db?", I will leave it here in case someone actually does solve it.
I've got a client application that's going to update a database every five minutes with the current time, and then I want to output this time as a last active table in a seperate VB application.
I know about mysql time, but I don't quite understand how I can use it to display when a client was last active.
I've looked around and found some stuff about mysql times but I don't fully understand it.
Any help would be great, I'm going to place the results in a ListView with 'Client Name' and 'Last Active' if this helps, and I already know how to connect to my database and retrieve information.
Thank you.
I'd recommend using a DATETIME for storage. The TIME data type is limited to a single "time of day" or a timespan. True, you're looking for the time of day, but to calculate the "Last Active" time you need the date attached. Consider these "Last Active" values (using a 24-hour clock):
3/26/2013 at 17:00:00 <-- this has the maximum time (5PM), but...
3/27/2013 at 08:15:00 <-- ...this is the most recent time because it happens the following day
In other words, you need the date so you can sort the time.
The MySQL DATETIME data type should be supported by VB.NET, but I've never used the two together so I can't guarantee it. To query and report just the time component of the date you have a ton of options. Here are two:
Query the entire date/time from MySQL and return it as a System.DateTime value to VB.NET. In VB.NET you can format it using DateTime.ToString to show only the time components. The MySQL query would go something like this:
SELECT ClientName, MAX(LastActive) AS LastActiveDateTime
FROM your_table
GROUP BY ClientName
Format the time in MySQL and return it as a String to VB.NET. In VB.NET you'll just need to display the string as is. The MySQL query would go something like this:
SELECT ClientName, DATE_FORMAT(MAX(LastActive), '%r') AS LastActiveTime
FROM your_table
GROUP BY ClientName
The format code %r in the above query will return the time in a 12-hour format with AM/PM, for example 07:55:29 PM. To return a 24-hour format (19:55:29), use %T instead.
