I explain the sql basic command
go to shell
SHOW DATABASES;
it show all the databases
USE
To select the any databased
SHOW TABLES
to show all the table
CREATE DATABSED
to create a databased name
CREATE TABLE {
<col_name>[data type]<keyword>,
<col_name>[data type]<keyword>,
<col_name>[data type]<keyword>
};
To create a table and add col in the table
DESC
to show the structure and description on the table
INSERT INTO
(col1,col2,col3...)VALUES(,value2>,);
SELECT FROM
if use * it select all the column
SELECT * FROM
WHERE {Condition}
condition will be comaparison = <,> ==, LIKE ,%,%_%
SELECT * FROM
WHERE {Condition} ORDER BY {colname} LIMIT {no}
if you write the order by ascending order
if you write ORDER BY DESC -descending order
