The to_date() function in Oracle is used to convert a string representation of a date to the date format used in the Oracle database. The syntax of this function is as follows:

The function to_date() takes two parameters: a string representing the date to be converted and a format specifying the date format.

The to_date() function can convert various formats of date strings into the date type in Oracle database. Here are some common date formats:

  1. ‘YYYY-MM-DD’ indicates the format of year-month-day.
  2. ‘MM/DD/YYYY’ signifies the format of month/day/year.
  3. ‘DD-MON-YYYY’ represents the format of day-month-year, for example: 23-OCT-2021.
  4. The format ‘YYYY-MM-DD HH24:MI:SS’ represents the year-month-day hour:minute:second, for example: 2021-10-23 15:30:45.

Here are some examples:

  1. Convert the string ‘2021-10-23’ to a date type.
  2. Parse the string ’10/23/2021′ into a date data type.
  3. Convert the string ’23-OCT-2021′ to a date type.
  4. Convert the string ‘2021-10-23 15:30:45’ to a date type.

It is important to note that the to_date() function requires the format of the date string to match exactly with the format specified in the format parameter, or else it will throw an error.
