To extract the number of days between two dates in Oracle SQL, you can use the "DATEDIFF" function. This function calculates the difference between two dates in days. Here's an example query:

SELECT DATEDIFF('2019-01-01', '2019-01-10') AS days_diff FROM dual;

This query will return the number of days between the two dates '2019-01-01' and '2019-01-10'. The result will be stored in the column "days_diff". You can replace the dates with your own date values to get the number of days between them.

In this example, `date_column1`

and `date_column2`

are the two date columns from which you want to calculate the number of days between them. `your_table`

is the name of your table. The `DATEDIFF`

function will return the number of days between the two dates.
