- Use the SELECT statement with CONVERT function and date format option for the date values needed.
- To get YYYY-MM-DD use this T-SQL syntax SELECT CONVERT(varchar, getdate(), 23)
- To get MM/DD/YY use this T-SQL syntax SELECT CONVERT(varchar, getdate(), 1)
SELECT Format(Now(), “dd mmmm yyyy”); You can use the Format() function with date values to specify the date format that you want to use for the date. This example query returns the current date in the long date format (01 December 2003).
- DMY – dd/MM/yyyy. Ex: 13/06/2018.
- YDM – yyyy/dd/MM. Ex: 2018/13/06.

A DATE data type contains both date and time elements. If you are not concerned about the time portion, then you could also use the ANSI Date literal which uses a fixed format ‘YYYY-MM-DD‘ and is NLS independent. For example, SQL> INSERT INTO t(dob) VALUES(DATE ‘2015-12-17’); 1 row created.
- Use CONVERT to VARCHAR: CONVERT syntax: CONVERT ( data_type [ ( length ) ] , expression [ , style ] ) …
- You can also convert to date: SELECT CONVERT(date, getdate()); It will return the current date value along with starting value for time. …
- Use CAST.
- CAST(date AS string)
- SELECT CURRENT_TIMESTAMP ‘date’, CAST(CURRENT_TIMESTAMP AS VARCHAR) ‘date as a string’;
- TO_CHAR(value, format);
- SELECT TO_CHAR(SYSDATE, ‘YYYY-MM-DD’) FROM dual;
- 2018-07-21.
MySQL DATE is one of the five temporal data types used for managing date values. MySQL uses yyyy-mm-dd format for storing a date value.

- Date date=Date.valueOf(str);//converting string into sql date.
- System.out.println(date);
- }
- }
Use STR_TO_DATE() method from MySQL to convert. The syntax is as follows wherein we are using format specifiers. The format specifiers begin with %. SELECT STR_TO_DATE(yourDateColumnName,’%d.
Data type | Format | User-defined fractional second precision |
---|---|---|
date | YYYY-MM-DD | No |
smalldatetime | YYYY-MM-DD hh:mm:ss | No |
datetime | YYYY-MM-DD hh:mm:ss[.nnn] | No |
datetime2 | YYYY-MM-DD hh:mm:ss[.nnnnnnn] | Yes |
We can convert the timestamp to date time with the help of FROM_UNIXTIME() function. Let us see an example. First, we will create a table with column of int type. Then we convert it to timestamp and again into date time.
To declare a date variable, use the DECLARE keyword, then type the @variable_name and variable type: date, datetime, datetime2, time, smalldatetime, datetimeoffset. In the declarative part, you can set a default value for a variable. The most commonly used default value for a date variable is the function Getdate().
First, create a table named datediff_test that has one column whose data type is DATETIME . Second, insert some rows into the datediff_test table. Third, use the DATEDIFF function to compare the current date and time with the value in each row of the datediff_test table.
- If you just need this for datetime. datetime. now() , please note that there is a method datetime. date. today() . …

CAST and CONVERT are two SQL functions used by programmers to convert one data type to another. … The CAST function is used to convert a data type without a specific format. The CONVERT function does converting and formatting data types at the same time.
- Get the date to be converted.
- Create an instance of SimpleDateFormat class to format the string representation of the date object.
- Get the date using the Calendar object.
- Convert the given date into a string using format() method.
- Print the result.

- public class StringToDateExample1 {
- public static void main(String[] args)throws Exception {
- String sDate1=”31/12/1998″;
- Date date1=new SimpleDateFormat(“dd/MM/yyyy”).parse(sDate1);

MySQL retrieves and displays DATE values in ‘ YYYY-MM-DD ‘ format. The supported range is ‘1000-01-01’ to ‘9999-12-31’ . The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in ‘ YYYY-MM-DD hh:mm:ss ‘ format.

Now to change sql server default date format from “mdy”(mm/dd/yyyy) to “dmy”(dd/mm/yyyy),we have to use SET DATEFORMAT command. Before changing the default date time format of sql server lets go through the way to know what format of date time is currently in use.

- public class SimpleDateFormatExample {
- public static void main(String[] args) {
- Date date = new Date();
- SimpleDateFormat formatter = new SimpleDateFormat(“dd/MM/yyyy”);
- String strDate= formatter.format(date);
The default format of the timestamp contained in the string is yyyy-mm-dd hh:mm:ss. However, you can specify an optional format string defining the data format of the string field.
Date date1 = new SimpleDateFormat(“dd/MM/yyyy”). parse(“10/12/2018”); It is showing the exact date.
