In Oracle, the TO_CHAR function can be used to convert a date (DATE) data type to a string (VARCHAR2) data type.

The specific grammar is as follows:

Convert the ‘date_value’ to a string using the specified ‘format’.

Among them, date_value is the date value to be converted, and format is the conversion format.

For example, to convert the current date to a string type, you can use the following statement:

Retrieve the current date in the format ‘YYYY-MM-DD’ from the system.

The output is similar to: 2022-03-01.

Here are some common examples of date formats:

  1. ‘YYYY-MM-DD’: Year-Month-Day
  2. YYYY-MM-DD HH24:MI:SS: Year-Month-Day Hour:Minute:Second
  3. MM/DD/YYYY: Month/Day/Year
  4. ‘DD-MON-YYYY HH:MI:SS’: Day-Month-Year Hour:Minute:Second

You can choose the date format that suits your needs.
