I know this is old, but it has an very searchable title, and there's no accepted answer.

The TO_TIMESTAMP function converts text representations of dates to a standard date/time format. From your question, it sounds like you have dates stored as characters in the format 'DD-MM-YYYY', but you want SQL Server DATETIME2(7) (based on the number of decimals in the seconds) as your output. It also seems you want the default time to be noon, rather than midnight, since your sample output shows 12:00 PM, not AM.

Using CONVERT with style 103 will change the European styled date to a DATETIME2(7), as shown below. But then you'll need to do a DATEADD to move from midnight (which will be the default value) to noon, which is twelve hours later.

DECLARE @DateSample NVARCHAR(10) = '17-04-2017';

SELECT CONVERT( DATETIME2(7), @DateSample, 103 );

--Results
--2017-04-17 00:00:00.0000000

SELECT DATEADD( HOUR, 12, CONVERT( DATETIME2(7), @DateSample, 103 ));

--Results
--2017-04-17 12:00:00.0000000

The SQL Server default is 24 hour time, so if you absolutely must switch to AM/PM designators, you'll have to convert it back to a string, which seems to be the opposite of what you're trying to do.

  • Which SQL? ANSI SQL, or perhaps SQL Server type SQL?
  • microsoft SQL 2016 @jarlh
  • Where are you starting from? Do you have a variable, a table, ... ? And what do you need to get? Populate some variable? print something? make a select query?
  • i need to make a select query @Aleksej
  • Ok, so I assume that you have a table with some data; please post the table structure of this table. Also, what should the result type be? a varchar2?
  • to_char is an oracle function, i wanted in MS SQL
  • I asked if you needed "a varchar2 output" and you said "yes", so I gave a solution for Oracle. Why did you answer that way if you needed something different?
