To extract the year from a date in Oracle, you can use the EXTRACT function or the TO_CHAR function with the 'YYYY' format. For example, you can use the EXTRACT function like this: SELECT EXTRACT(YEAR FROM DATE_COLUMN) FROM TABLE_NAME; Or you can use the TO_CHAR function like this: SELECT TO_CHAR(DATE_COLUMN, 'YYYY') FROM TABLE_NAME; Either of these methods will return the year from the date stored in the DATE_COLUMN of the specified table.
