When I get TODAY in SELECT in PB, it returns 1900/1/1
date var
Select TODAY() Into :var From DUMMY
But when I assign to variable TODAY(), it works as expected
date var
var = today()
I use MS SQL Server 2016 and PowerBuilder 12.5.
I've supposed that the problem is in different date formats, but I have changed date format at my Windows locale in the way, that PB TODAY() returns 2018-10-08 and MSSQL GetDate() returns 2018-10-08 18:25:23.207
So date parts have the same formats.
The problem is not in DUMMY table since I have created MS SQL DUMMY table and inserted 1 row in it.
Also I'm wondering if there are any difference in SELECT TODAY() and var = TODAY()?
I suppose that 1st variant returns MS SQL server time but 2nd returns local time. Is not is?
Try below SQL.
Select getdate() into :var From DUMMY;
You provided your own answer: Today() is a PowerScript function, GetDate() is the function on MS SQL. If you’re executing SQL, it needs to be a valid SQL statement for the server you’re executing against (except for the INTO :var part), and can’t include a PowerScript function.
Two other things:
“FROM DUMMY” is an Oracle thing, and I’m pretty sure it won’t work on MS. (You’re capturing your error codes after executing the SQL, right?)
I won’t say this is likely a critical problem, but as you point out, GetDate returns a datetime; I’d recommend that as your data type for the capture variable.
And yes, GetDate() will be your server’s date/time, Today() will be based on the local workstation.
Good luck.

Is there a way to alter the outcome of getdate() while still using it as a default value? E.g. being able to plus or minus x number of hours.
The situation:
a German hosted server (GMT+2) with some end users in Australia (GMT+10). One column is using the default getdate() value therefore is inserting German time. Some code is generating a DateTime based on Australia time so there are 8 hours difference.
The objective:
For several good reasons the aim is to handle this on the database and not touch application code. I would like to add 8 hours onto the German getdate() default database value....... or handle this some other way on the database
you can use default value using DATEADD() function to add 8 hours to the date:
create table dbo.foo
(
dateColumn datetime default (dateadd(hour,8,getdate()))
)
I don't see any such option and it is little dangerous too. You can create a function with the same name GETDATE in your database, but that would require you to prefix with dbo(or schema name) while calling the function.
So, you may need to write your own function and make use of GETUTCDATE() and add delta according to timezone.
I'm very new to sql so im not sure how i would go about changing the line below to take in account for the new year. The sql server query i'm running will run on January 1st of 2014. Will this work in sql server 2008 or will it need to be changed for the new year to capture 2013?
DT.[DOS-DATE] between convert(date,GETDATE()-7) and convert(date,GETDATE())
This query takes records between the last 7 days and today. The year does not matter in that condition.
It's better to use explicit operators on date. Also, no reason to call GETDATE() twice. Try this instead:
DECLARE #Now DATETIME = GETDATE()
...
DT.[DOS-DATE] between convert(date,DATEADD(day, -7, #Now)) and convert(date,#Now)
However, technically your existing code will work.
Also, you may want to take a look at this for potential issues with using BETWEEN:
What do BETWEEN and the devil have in common?
We just upgraded to SQL Server 2012 from 2005. While I'm a novice, something this simple couldn't be this difficult. I used to be able to pull data from a table based on the date vs date and time. As it now stands I have:
Select * from receipts_table where receipt_cancel_date = '2013-09-20'
before we upgraded this would work fine. How can I run this and actually get the desired results as I know there's receipts with a cancel date of 2013-09-20.
Thanx
If you are passing string for a date parameter, best format is ISO (yyyymmdd) format. Otherwise even though your string work in some servers it might not work in another depending on the culture of the server. ISO format is culture independent.
Also remove the time part from receipt_cancel_date column by converting it to a DATE (if DATETIME) for comparison purpose.
Try this:
Select * from receipts_table
where convert(date, receipt_cancel_date) = convert(date,'20130920')
Or use 120 style with your format:
Select * from receipts_table
where convert(date, receipt_cancel_date) = convert(date,'2013-09-20',120)
I'm currently using
Convert(varchar, Getdate(), 101)
to insert only date part of system date into one of my sql server database tables.
my question is: is it the right way to do that or is there any other better method to do it?
I don't understand why you're converting the GETDATE() output (which is DATETIME already) to a VARCHAR and then SQL Server would convert it back to DATETIME upon inserting it again.
Just use:
INSERT INTO dbo.YourTable(SomeDateTimeColumn)
VALUES(GETDATE())
If you're doing that conversion to get rid of the time portion of the DATETIME, you should better:
use the DATE datatype (available in SQL Server 2008 and newer) to store only the DATE (no time)
if you're using SQL Server 2005 or earlier, use this conversion instead - should be much more efficient than two conversions!
INSERT INTO dbo.YourTable(SomeDateTimeColumn)
VALUES(DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0))
Update: did some performance testing, and in this particular case, it seems the amount of work that SQL Server needs to do is really the same - regardless of whether you're using the convert to varchar stripping the time and back to datetime approach that you already have, or whether you're using my get the number of days since date 0 approach. Doesn't seem to make a difference in the end.
The BEST solution however would still be: if you only need the date anyway - use a column of type DATE (in SQL Server 2008 and newer) and save yourself any conversions or manipulations of the GETDATE() output altogether.
I've been storing date times in local time and I need to convert them all to Universal time.
How can I do this in SQL Server 2008?
By local time, I mean either BST or GMT.
i.e. I stored DateTime.Now() from .NET throughout the year, and I now need to homogenise the data.
Thanks!
please consider sending already from the c# the utc
also, there is SELECT GETUTCDATE()
in sql server

edit
if you need to update so
UPDATE SomeTable
SET DateTimeStamp = DATEADD(hh, DATEDIFF(hh, GETDATE(), GETUTCDATE()), DateTimeStamp)
Use the DATEADD function of SQL Server. You just have to know to no. of hours difference from your local to time to UTC.
