Setting up the Globalization Support EnvironmentTable 11–1 (Cont.) Examples of Short Date FormatsCountry Description ExampleChina yyyy-mm-dd 2005-02-28UK dd/mm/yyyy 28/02/2005US mm/dd/yyyy 02/28/2005This topic includes the following parameters:■■NLS_DATE_FORMATNLS_DATE_LANGUAGE11.2.4.1.1 NLS_DATE_FORMAT The NLS_DATE_FORMAT parameter defines the defaultdate format to use with the TO_CHAR and TO_DATE functions. The NLS_TERRITORYparameter determines the default value of NLS_DATE_FORMAT. The value of NLS_DATE_FORMAT can be any valid date format mask. For example:NLS_DATE_FORMAT = "MM/DD/YYYY"The Oracle default date format may not always corresponds to the cultural specificconvention used in a given territory. You can utilize the short date and long dateformat in SQL, using the 'DS' and 'DL' format masks respectively, to obtain dates ina more localized formats. The examples in this topic show the differences betweensome of the date formats.Example 11–5Using the Default, Short, and Long Date Formats-- Use an ALTER SESSION statement to change the territory to America,-- and the language to AmericanALTER SESSION SET NLS_TERRITORY = America NLS_LANGUAGE = American;-- After the session is altered, select the dates with the format masksSELECT hire_date, TO_CHAR(hire_date,'DS') "Short",TO_CHAR(hire_date,'DL') "Long" FROM employeesWHERE employee_id IN (111, 112, 113);The results of the query in Example 11–5 are similar to the following:HIRE_DATE Short Long--------- ---------- -----------------------------30-SEP-97 9/30/1997 Tuesday, September 30, 199707-MAR-98 3/7/1998 Saturday, March 07, 199807-DEC-99 12/7/1999 Tuesday, December 07, 1999To add string literals to the date format, enclose the string literal with double quotes.Note that when double quotes are included in the date format, the entire value mustbe enclosed by single quotes. For example:NLS_DATE_FORMAT = '"Date: "MM/DD/YYYY'11.2.4.1.2 NLS_DATE_LANGUAGE The NLS_DATE_LANGUAGE parameter specifies thelanguage for the day and month names produced by the TO_CHAR and TO_DATEfunctions. NLS_DATE_LANGUAGE overrides the language that is specified implicitly byNLS_LANGUAGE. NLS_DATE_LANGUAGE has the same syntax as the NLS_LANGUAGEparameter, and all supported languages are valid values.NLS_DATE_LANGUAGE also determines the language used for:■Month and day abbreviations returned by the TO_CHAR and TO_DATE functions11-8 SQL Developer Online Help
Setting up the Globalization Support Environment■ Month and day abbreviations used by the default date format (NLS_DATE_FORMAT)Example 11–6 shows how to use NLS_DATE_LANGUAGE to set the date language toFrench.Example 11–6 NLS_DATE_LANGUAGE=FRENCH, Month and Day Names-- set NLS_DATE_LANAGUAGE for this user sessionALTER SESSION SET NLS_DATE_LANGUAGE = FRENCH;-- display the current system dateSELECT TO_CHAR(SYSDATE, 'Day:Dd Month yyyy') FROM DUAL;You should see output similar to the following, depending on the current system date:TO_CHAR(SYSDATE,'DAY:DDMON--------------------------Jeudi :06 Octobre 2005The default date format uses the month abbreviations determined by NLS_DATE_LANGUAGE. For example, if the default date format is DD-MON-YYYY and NLS_DATE_LANGUAGE = FRENCH, then insert a date as follows:INSERT INTO table_name VALUES ('12-Févr.-1997');See Also: Oracle Database SQL Reference for information on dateformat models11.2.4.2 Time FormatsDifferent time formats are shown in Table 11–2.Table 11–2Examples of Time FormatsCountry Description ExampleEstonia hh24:mi:ss 13:50:23Germany hh24:mi:ss 13:50:23China hh24:mi:ss 13:50:23UK hh24:mi:ss 13:50:23US hh:mi:ssxff am 1:50:23.555 PMThis topic contains information about the following parameters:■■NLS_TIMESTAMP_FORMATNLS_TIMESTAMP_TZ_FORMAT11.2.4.2.1 NLS_TIMESTAMP_FORMAT NLS_TIMESTAMP_FORMAT defines the defaultdate format for the TIMESTAMP and TIMESTAMP WITH LOCAL TIME ZONE datatypes. The NLS_TERRITORY parameter determines the default value of NLS_TIMESTAMP_FORMAT. The value of NLS_TIMESTAMP_FORMAT can be any validdatetime format mask.The following example shows a value for NLS_TIMESTAMP_FORMAT:NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH:MI:SS.FF'Working in a Global Environment 11-9
