How to Convert 'Dd-Mm-Yyyy' to 'Dd-Mmm-Yyyy' In Postgresql?

2 minutes read

To convert a date from 'dd-mm-yyyy' format to 'dd-mmm-yyyy' format in Postgresql, you can use the TO_CHAR() function. You can use the following query to achieve the desired conversion:


SELECT TO_CHAR(your_date_column, 'dd-mon-yyyy') AS formatted_date FROM your_table;


Replace 'your_date_column' with the actual column name that contains the date in 'dd-mm-yyyy' format and 'your_table' with the name of your table. This query will return the date in 'dd-mmm-yyyy' format.


How to convert 'dd-mm-yyyy' to 'dd-mmm-yyyy' in PostgreSQL efficiently?

One efficient way to convert 'dd-mm-yyyy' to 'dd-mmm-yyyy' in PostgreSQL is by using the TO_CHAR function with the appropriate format specifier for the month.


Here's an example query to achieve this conversion:

1

SELECT TO_CHAR('30-01-2022'::date, 'DD-Mon-YYYY') AS converted_date;


In this query, 'DD' represents the day, 'Mon' represents the abbreviated month name (e.g. Jan for January), and 'YYYY' represents the year. By using 'Mon' as the format specifier, PostgreSQL will automatically convert the month to its abbreviated form.


This query will output '30-Jan-2022', which is the 'dd-mmm-yyyy' format you are looking for.
