TALK WITH YOUR DATABASE
SQL is a structured query language used to manage the database. SQL allows you to store, manipulate, and retrieve data from the database.
Databases are where data is stored in tables. Each table contains rows and columns, where the columns represent the attributes (e.g. Name, Age, Email) and the rows represent actual data entries (e.g. Alex, 26, alex@gmail.com ).
THE BASICS: SELECT, FROM
The SELECT keyword is used to retrieve data from a table in the database, whereas the FROM keyword is used to specify the table from which the data should be retrieved.
FILTER DATA: WHERE
The WHERE clause allows you to filter the data based on a condition. It is used to retrieve only those records that meet the specified condition.
SORT DATA: ORDER BY
The ORDER BY clause allows you to sort the query results by one or more columns, either in ascending( ASC ) or descending(DESC) order.
Conclusion
SQL is more like a tool that is used to interact with the table in the database. By using simple clauses like SELECT, FROM, WHERE, and ORDER BY, you can retrieve the information you are looking for.
Whether you’re a beginner or an experienced professional in the field of data, having SQL skills is a must to manage data efficiently.
