![]() ![]() In other countries/regions such as Germany and France, the DATEFORMAT is dmy, meaning 'dd-mm-yyyy'. It's international because the four digits of the year are unambiguous, and no country/region on Earth uses the archaic format of ydm. This format is considered to be the international format. The format's parts are in a sensible sequence of largest unit to smallest. In Japan and China, the DATEFORMAT of ymd is used. The numeric value of '2018' is too large to be a day. If instead mdy was specified, then the same '01-03-2018' string would mean the third day of January in 2018.Īnd if ymd was specified, there's no guarantee of what the output would be. The preceding dmy format says that an example date string of '01-03-2018' would be interpreted to mean the first day of March in the year 2018. ![]() *** Actual output: For the two months, note the 11 versus the 10. If Croatian, then listopad translates to month 10 ( October in English).Ĭode example of SET LANGUAGE -SELECT alias FROM sys.syslanguages ORDER BY alias ĭECLARE NVARCHAR(32) = '28 listopad 2018'.If Polish, then listopad translates to month 11 ( November in English).But which month it is depends on the language the SQL system believes is being used: But is the name in English, or Polish, or Croatian, or in another language? And, will the user's session be set to the correct corresponding LANGUAGE?įor example, consider the word listopad, which is the name of a month. SET LANGUAGE example: Month name in PolishĪ character string can be the name of a month. You control these nondeterministic conversions by accounting for the settings of SET LANGUAGE and SET DATEFORMAT. The reason is that such conversions are often nondeterministic. Use caution when allowing conversion of your CHARACTER strings into DATE data types.
