To update the time in Oracle SQL, you can use the UPDATE statement along with the TO_DATE function to change the time component of a datetime column. Here is an example of how you can update the time component of a datetime column in a table:

UPDATE your_table
SET date_column = TO_DATE(TO_CHAR(date_column, 'DD-MON-YYYY') || ' 12:34:56', 'DD-MON-YYYY HH24:MI:SS')
WHERE your_condition;

In this example:

  • your_table is the name of the table you want to update
  • date_column is the datetime column you want to update
  • 12:34:56 is the new time you want to set
  • your_condition is the condition that determines which rows to update

This query uses the TO_CHAR function to extract the date part of the datetime column, appends the new time, and then uses the TO_DATE function to convert it back into a datetime value. The UPDATE statement then updates the datetime column with the modified value.

Make sure to adjust the table and column names, new time value, and condition to fit your specific use case.
