Hi,

 

I have a problem with time precision this is the value in the database of a time column

16:29:15.983

Put displays in a datawindow as

16:29:15.000

Now this is not a problem as such because im not that bothered about factions of seconds , the issue is when the user tries to update the datawindow we get a ROW CHANGED BETWEEN RETREIVE AN UPDATE.

Now the workaround is for someone to go into the database and remove the factions and then it works.

But is there a way we can fix the datawindow to show the fractions?

 

I have attached screen show of what is shows in SQL anywhere console and what it shows in datawindow.

I requested support for datetime2. They have no plans to support it.

https://www.appeon.com/standardsupport/track/view?id=8603

In my testing, the time and datetime variables can handle 6 digits but the Now() function only returns 3.

Although the above post refers to MS SQL Server, it sounds like the same issue that you are experiencing in SQL Anywhere.

Hi.

Have you tried to set time format to "hh:mm:ss.fff"? If not, what do you see when doing so?

Andreas.

I think it might have to do something with the datetime format in your SQLCA dbparm settings. I'm not an expert in sqlanywhere, but that's where I would start to look at.

The issue I believe is because the datawindow cant show the true value from the database it alaways thinks there is change bewtween retrieve and update.

Hi Marc;

=> "If i go into the datawindow and make these no updateable then its fine."

Exactly, that is what is normally done by most PB developers. :-)

However, there is the issue of PB not supporting the DatTime2 and DateTimeOffset data types (unfortunately). :-(

So PB Apps will need to stay away from using those types of columns.

Instead, updating these with a DBMS Trigger as a workaround.

Regards .. Chris

I have fixed the issue for myself it was the updatable properties of the datawindow wes set to update all fields instead of just key fields.



I think your previous reply helped me work that out , thanks for that.



There is still an issue with time precision within Appeon and this is what I have noticed.



Apps delpoyed via powerServer save time fields with milliseconds while win32 apps do not save the milliseconds and are always 000, why this is unclear but it doesn't cause me an issue now.
