SQL - Select AND
SQL query using the SELECT ... WHERE clause with the AND logical operator to retrieve full details of tutorials based on multiple conditions, along with the meaning, usage, syntax, example, and explanation:
Usage:
The SELECT ... WHERE clause with the AND operator is used to retrieve rows that satisfy multiple conditions simultaneously. It allows you to combine multiple conditions in a single query and retrieve rows that match all of those conditions.
Syntax:
SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 ...;
Example:
Let's assume we have a "Tutorials" table with the following columns:
TutorialID (unique identifier for each tutorial)
Title (title of the tutorial)
IsFull (1 if the tutorial is complete, 0 if it's not complete)
Views (number of views for the tutorial)
To select the full details of tutorials that are complete (IsFull = 1) and have more than 1000 views, we can use the following query:
SELECT TutorialID, Title, Details
FROM Tutorials
WHERE IsFull = 1 AND Views > 1000;
Explanation:
The SELECT statement specifies the columns you want to retrieve from the table. In this case, we're selecting TutorialID, Title, and Details.
The FROM clause indicates the table from which we want to retrieve data. In this case, it's the "Tutorials" table.
The WHERE clause is used to specify conditions to filter the rows. Here, we're using the AND operator to combine multiple conditions.
In the first condition, IsFull = 1, we check if the IsFull column is equal to 1, indicating a complete tutorial.
In the second condition, Views > 1000, we check if the Views column has a value greater than 1000.
By executing this query, you will retrieve the TutorialID, Title, and Details of tutorials that are complete (IsFull = 1) and have more than 1000 views (Views > 1000).
