To create a light speed out effect with CSS, you can try to run the following code:Live Demo .animated { background-image: url(/css/images/logo.png); background-repeat: no-repeat; background-position: left top; padding-top:95px; margin-bottom:60px; -webkit-animation-duration: 1s; animation-duration: 1s; -webkit-animation-fill-mode: both; animation-fill-mode: both; } @-webkit-keyframes lightSpeedOut { 0% { -webkit-transform: translateX(0%) skewX(0deg); opacity: 1; } 100% { -webkit-transform: translateX(100%) skewX(-30deg); opacity: 0; } } @keyframes lightSpeedOut { 0% { transform: translateX(0%) skewX(0deg); opacity: 1; } 100% { transform: translateX(100%) skewX(-30deg); opacity: 0; } } .lightSpeedOut { -webkit-animation-name: lightSpeedOut; animation-name: lightSpeedOut; -webkit-animation-timing-function: ease-in; animation-timing-function: ease-in; } .animated.lightSpeedOut { -webkit-animation-duration: 0.25s; animation-duration: 0.25s; } Reload page function myFunction() { location.reload(); }
For fetching a particular row as output, we need to use WHERE clause in the SELECT statement. It is because MySQL returns the row based on the condition parameter given by us after WHERE clause.ExampleSuppose we want to fetch a row which contains the name ‘Aarav’ from student table then it can be done with the help of the following query −mysql> Select * from Student WHERE Name = 'Aarav'; +------+-------+---------+---------+ | Id | Name | Address | Subject | +------+-------+---------+---------+ | 2 | Aarav | Mumbai | History | +------+-------+---------+---------+ 1 row in set (0.00 sec)
The SELECT command is used to fetch data from the MySQL database. You can use this command at mysql> prompt as well as in any script like PHP.SyntaxHere is generic syntax of SELECT command to fetch data from the MySQL table −SELECT field1, field2, ...fieldN FROM table_name1, table_name2... [WHERE Clause] [OFFSET M ][LIMIT N]Some important points about SELECT statement are as follows −We can use one or more tables separated by a comma to include various conditions using a WHERE clause, but the WHERE clause is an optional part of the SELECT command.We can fetch one or more fields in ...

We can use conditional insert i.e. WHERE clause with INSERT INTO command in the case of new row insertion. It can be done with following ways −With the help of dummy tableIn this case, we insert the value from dummy table along with some conditions. The syntax can be as follows −INSERT INTO table_name(column1, column2, column3, …) Select value1, value2, value3, … From dual WHERE [conditional predicate];Examplemysql> Create table testing(id int, item_name varchar(10)); Query OK, 0 rows affected (0.15 sec) mysql> Insert into testing (id, item_name)Select 1, 'Book' From Dual Where 1=1; Query OK, 1 row affected (0.11 sec) ...

We can insert the values into a table with the help of the self-computed output returned by MySQL. In this case, we do not need to use dummy ‘dual’ table. The syntax can be as follows −INSERT INTO table_name(column1, column2, column3, …) Select value1, value2, value3, …;ExampleIn the example below, we have inserted the values in ‘testing’ table by using the MySQL self-computed output.mysql> Create table testing(id int, item_name varchar(10)); Query OK, 0 rows affected (0.15 sec) mysql> Insert into testing (id, item_name)Select 1, 'Book'; Query OK, 1 row affected (0.11 sec) Records: 1 Duplicates: 0 Warnings: 0 ...

MySQL EXTRACT() function can use following compound units −SECOND_MICROSECONDMINUTE_MICROSECONDHOUR_MICROSECONDDAY_MICROSECONDMINUTE_SECONDHOUR_SECONDHOUR_MINUTEDAY_SECONDDAY_MINUTEDAY_HOURYEAR_MONTHSome of the examples of these compound units used in EXTRACT() function are as follows −mysql> Select EXTRACT(YEAR_MONTH from '2017-10-20'); +---------------------------------------+ | EXTRACT(YEAR_MONTH from '2017-10-20') | +---------------------------------------+ | 201710 | +---------------------------------------+ 1 row in set (0.00 sec)Above query will return the year and month value from the date.mysql> Select EXTRACT(DAY_HOUR from '2017-10-20 05:46:45'); +----------------------------------------------+ | EXTRACT(DAY_HOUR from '2017-10-20 05:46:45') | +----------------------------------------------+ | ...

INSERT command is used to add values to the columns of a MySQL table. We need to specify the values in INSERT command for all the columns as follows −SyntaxINSERT INTO table_name values(value1, value2, …)ExampleSuppose we have a table named ‘Stock’ with three columns ‘Item_id’, ‘Item_name’ and ‘Item_rate’ then with the help of following query we can add values in these columns.mysql> INSERT INTO Stock values(1, 'HistoryBook', 250); Query OK, 1 row affected (0.07 sec) mysql> INSERT INTO Stock values(2, 'DBMSBook', 280); Query OK, 1 row affected (0.10 sec) mysql> Select * from Stock; +---------+-------------+-----------+ | item_id | ... Read More
We can do it by providing unit value ‘quarter’ to EXTARCT() function. Examples are as follows −mysql> Select EXTRACT(Quarter from '2017-07-29'); +------------------------------------+ | EXTRACT(Quarter from '2017-07-29') | +------------------------------------+ | 3 | +------------------------------------+ 1 row in set (0.00 sec)Above query will give the value of quarter from a particular given date.mysql> Select EXTRACT(Quarter from now()); +-----------------------------+ | EXTRACT(Quarter from now()) | +-----------------------------+ | 4 | +-----------------------------+ 1 row in set (0.00 sec)Above query will give the value of quarter from the current date.
CREATE TABLE command with LIKE keyword will be able to define the structure of a MySQL table same as the structure of another table.SyntaxCREATE TABLE new_table LIKE old_table;Examplemysql> Create table employee(ID INT PRIMARY KEY NOT NULL AUTO_INCREMENT, NAME VARCHAR(20)); Query OK, 0 rows affected (0.21 sec) mysql> Describe employee; +-------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------+-------------+------+-----+---------+----------------+ | ID | int(11) | NO | PRI | NULL | auto_increment | | NAME | varchar(20) | YES | ...

For creating a new table just like old one along with its data, trigger, and indexes, we need to run following two queriesCREATE TABLE new_table LIKE old_table; INSERT new_table SELECT * from old_table;Examplemysql> Create table employee(ID INT PRIMARY KEY NOT NULL AUTO_INCREMENT, NAME VARCHAR(20)); Query OK, 0 rows affected (0.21 sec) mysql> Describe employee; +-------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------+-------------+------+-----+---------+----------------+ | ID | int(11) | NO | PRI | NULL | auto_increment | | NAME | varchar(20) | ...
