Suppose if we are trying to add the numbers having non-numeric text after them, then MySQL simply discard the non-numeric text and evaluates the addition of numeric values along with warnings. Following example will exhibit this −Examplemysql> Select '1525 Kg' + '200 Oz'As Total; +-------+ | Total | +-------+ | 1725 | +-------+ 1 row in set, 2 warnings (0.00 sec)
If we are trying to add two numbers that are contained in quotes, means we are treating the string as a number. In this case, MySQL converts the value into the closet numeric equivalent and evaluates the result. Following example will demonstrate it.Examplemysql> Select '1525' + '200'As Total; +-------+ | Total | +-------+ | 1725 | +-------+ 1 row in set (0.00 sec)
MySQL cannot perform a case-sensitive comparison when comparing characters. It can be illustrated with the following example from table ‘Employee’ having the following data −mysql> Select * from Employee; +----+--------+--------+ | ID | Name | Salary | +----+--------+--------+ | 1 | Gaurav | 50000 | | 2 | Rahul | 20000 | | 3 | Advik | 25000 | | 4 | Aarav | 65000 | | 5 | Ram | 20000 | | 6 | Mohan | 30000 | | 7 | Aryan | NULL | | 8 | Vinay | NULL | +----+--------+--------+ 8 rows in set (0.09 sec)The result set of the following query shows that MySQL is not case sensitive when comparing characters.mysql> Select * from Employee WHERE Name IN ('gaurav','RAM'); +----+--------+--------+ | ID | Name | Salary | +----+--------+--------+ | 1 | Gaurav | 50000 | | 5 | Ram | 20000 | +----+--------+--------+ 2 rows in set (0.00 sec)
The text-overflow property is used to determine how overflowed content that is not displayed is signaled to users with CSS.ExampleYou can try to run the following code to implement a text-overflow property in CSS:Live Demo p.text1 { white-space: nowrap; width: 200px; border: 1px solid #000000; overflow: hidden; text-overflow: clip; } p.text2 { ...

To understand it consider the data, as follows, from the table ‘Students’ −mysql> Select * from Students; +----+-----------+-----------+----------+----------------+ | id | Name | Country | Language | Course | +----+-----------+-----------+----------+----------------+ | 1 | Francis | UK | English | Literature | | 2 | Rick | USA | English | History | | 3 | Correy | USA | English | Computers | | 4 | Shane | France | ...

We would need special privileges to create or to delete a MySQL database. Following is the syntax of dropping a database using mysqladmin binary −Syntax[root@host]# mysqladmin -u root -p drop db_name Enter password:******Here, db_name is the name of the database we want to delete.ExampleFollowing is an example to delete a database named TUTORIALS −[root@host]# mysqladmin -u root -p drop TUTORIALS Enter password:******The above statement will give you a warning and it will confirm if you really want to delete this database or not.Dropping the database is potentially a very bad thing to do. Any data stored in the database will be ... Read More

Once we get connected to the MySQL server, it is required to select a database to work with. This is because there might be more than one database available with the MySQL Server.It is very simple to select a database from the mysql> prompt. We can use SQL command ‘use’ to select a database. To illustrate it we are selecting the database named ‘Tutorials’ in the following example −Example[root@host]# mysql -u root -p Enter password:****** mysql> use TUTORIALS; Database changed mysql>Now, we have selected the TUTORIALS database and all the subsequent operations will be performed on the TUTORIALS database.Read More
The text-align-last property is used to align the last line of the text.
