1         2010-10-12
2         2009-10-12
3         2010-10-12
4         2009-10-12
5         2010-10-12
6         2010-10-12
7         2010-10-12
8         2009-10-12
9         2010-10-12
10        2010-10-12
11        2009-10-12

Starter with: see if you can find a function (in the documentation - ur guess) that returns the year from a date column.

Then try just selecting these rows/cols.

Then if that looks good, try grouping.

Incrementally work your way to the solution.

Code:

SELECT SUBSTR(CHAR(Join_DT),1,4),       
       COUNT(Emp_ID)               
 FROM Employee
 GROUP BY SUBSTR(CHAR(Join_DT),1,4);

you can also use YEAR function to extract year part in the date column directly instead of SUBSTR.

SELECT CHAR(YEAR(Join-Dt)), COUNT(Emp_ID)
FROM Employee
GROUP BY CHAR(YEAR(Join_Dt))
WITH UR;
