How to count each week data in oracle?

To count each week data in Oracle, you can use the following SQL query:

1
2
3
4
5
6
7
8
9

SELECT 
    TO_CHAR(date_column, 'IW') AS week_number,
    COUNT(*) AS week_data_count
FROM 
    your_table_name
GROUP BY 
    TO_CHAR(date_column, 'IW')
ORDER BY 
    TO_CHAR(date_column, 'IW');

Replace date_column with the name of the column that contains the date data in your table, and your_table_name with the name of your table. This query will group the data by week number and count the number of records for each week. The week number is obtained using the TO_CHAR function with the 'IW' format, which returns the ISO week number of a date.

This query will give you a count of data for each week in your table.
