Finding Two Consecutive Dates

Question

Hi I have a table "EMP_LEAVE" with some records as below

Employee | Leave_Start_Date | Leave_End_Date
1          22-09-2014           26-09-2014
1          29-09-2014           03-10-2014
1          15-12-2014           19-12-2014
1          22-12-2014           24-12-2014
2          07-01-2014           10-01-2014
2          13-01-2014           17-01-2014
2          20-01-2014           24-01-2014
3          10-02-2014           13-02-2014
3          17-02-2014           21-02-2014

I want to write a SQL query to find:

1. Employee who has taken leaves more than or equal to "Two Consecutive" weeks or I should say Two weeks in a row?

2. If Yes then whats there Leave_Start_Date and Leave_End_Date for those total leaves?

Any help or direction will be appreciated.

Answer 1

You can write some simple query as below.

 select employee, Leave_start_date, Leave_end_date from emp_leave where datediff(Leave_start_date, Leave_end_date) >= 15 

This query will give you the employees which have taken leave for more than 15 days.
