Convert Oracle Timestamp to Number

To convert an Oracle timestamp to a number, you can use the following method:

1. Use the TO_NUMBER function.

SELECT TO_NUMBER(TO_CHAR(your_timestamp_column, 'YYYYMMDDHH24MISS')) AS timestamp_number
FROM your_table;

1. Utilize the EXTRACT function:

SELECT EXTRACT(YEAR FROM your_timestamp_column) * 10000000000 +
       EXTRACT(MONTH FROM your_timestamp_column) * 100000000 +
       EXTRACT(DAY FROM your_timestamp_column) * 1000000 +
       EXTRACT(HOUR FROM your_timestamp_column) * 10000 +
       EXTRACT(MINUTE FROM your_timestamp_column) * 100 +
       EXTRACT(SECOND FROM your_timestamp_column) AS timestamp_number
FROM your_table;

These methods can convert Oracle timestamps into numerical formats, making it easier to perform numerical calculations or comparisons.
