I needed some help in creating a query. I have not tried much due to lack of awareness of SQL. So I turn to everyone on this forum for help.

I'm fetching 2 dates, each from a different table and want to check if a weekend exists between those two dates.

Also if there exists a weekend I want to calculate the time elapsed between those two date, excluding the hours of the weekend(minus 48hrs).

If someone can help me or direct me in creating such a query, please do.

Hint :

SQL> select TRUNC(SYSDATE) TO_DATY from dual;


SQL> select TRUNC(SYSDATE) - TO_DATE('01-JAN-2008','DD-MON-YYYY') DIFF from dual;


SQL>  SELECT TO_CHAR(TO_DATE('06-JAN-2008','DD-MON-YYYY'),'DAY') DAY from dual;



Thumbs Up
