If we want to compare the data values of two columns then we need to provide the name of the columns as arguments of MySQL STRCMP() function. Suppose we have a table named ‘Marks’ which contains the name of the student and their secured marks in different subjects. Now, if we want to know that a particular student has got more or less or equal marks in two subjects then it can be illustrated using STRCMP() function as follows −
Example
mysql> Select Name, STRCMP(Math,Hindi) from student marks WHERE Name = 'Rahul'; +-------+--------------------+ | Name | STRCMP(Math,Hindi) | +-------+--------------------+ | Rahul | 1 | +-------+--------------------+ 1 row in set (0.00 sec)
The query above will compare the marks of Math and Hindi for a student named ‘Rahul’. It is clear from the result set that Rahul secure more marks in Math rather than in Hindi.
