Oracle UPDATE Statement: Modify Data in a Field

To modify data in a field, you can use the UPDATE statement. Below is the general syntax for updating field data.

UPDATE table_name
SET column_name = new_value
WHERE condition;

table_name is the name of the table where data needs to be modified, column_name is the name of the field to be modified, new_value is the new value to be set, and condition is the filter criteria to determine which rows need to be modified.

For example, if you want to change the age of a user named “Tom” to 25, you can use the following SQL statement:

UPDATE users
SET age = 25
WHERE name = 'Tom';

After executing the above statement, the age of the user named “Tom” will be changed to 25 years old.
