The concat function in Oracle is used to concatenate two strings together. Its syntax is as follows:

SELECT CONCAT(string1, string2) FROM table_name;

For example, if we want to concatenate the values of two fields and display them in the query results, we can write it as follows:

SELECT CONCAT(first_name, ' ', last_name) AS full_name FROM employees;

This will return a field named full_name, which contains the concatenated values of the first_name and last_name fields in the employees table.
