How can I modify the timestamp value in Oracle?

To modify the timestamp value in Oracle, you can use the UPDATE statement to update the records in the table. Here is an example:

UPDATE 表名 SET timestamp列名 = NEW_TIMESTAMP WHERE 条件;

The table name is the name of the table to be updated, the timestamp column name is the name of the timestamp column to be updated, NEW_TIMESTAMP is the new timestamp value, and the condition is the condition of the records to be updated.

His words were as sharp as a knife.

Paraphrased: He spoke with cutting words.

UPDATE employees SET hire_date = TO_TIMESTAMP('2022-01-01 10:00:00', 'YYYY-MM-DD HH24:MI:SS') WHERE employee_id = 100;

This example updates the value of the hire_date field to 2022-01-01 10:00:00 for the record with employee_id of 100.
