Answer / guru manohar
You can use COUNT(field),MIN(field),MAX(field) functions for
character fields.
For example there is a table called DEPARTMENTS contains the
data as shown below:
DEPARTMENT_ID DEPARTMENT_NAME
---------------------------------
10 Administrator
20 Marketing
50 Shipping
60 IT
1)SELECT COUNT(department_name)
From DEPARTMENTS;
Output: 4
Note: Bcoz there are 4 rows with DEPARTMENT_NAME
2)SELECT MAX(department_name)
From DEPARTMENTS;
Output: Shipping
Note: Bcoz Shipping comes last in sorting by Ascending
3)SELECT MIN(department_name)
From DEPARTMENTS;
Output: Administrator
Note: Bcoz Administrator comes first in sorting by Ascending
