Oracle查询，每月提取两天之间的数据

Question

How to extract data between 2 days for every month. For example, say the date range is between 2nd and 10th. Then I need to extract data for 2nd and 10th of every month from the table.

Answer 1

Use EXTRACT

SELECT *
FROM   table_name
WHERE  EXTRACT( DAY FROM date_column ) BETWEEN 2 AND 10;

or TO_CHAR then TO_NUMBER :

SELECT *
FROM   table_name
WHERE  TO_NUMBER( TO_CHAR( date_column, 'DD' ) ) BETWEEN 2 AND 10;
