How to Get the Number Of Rows Returned In MySQL?

To get the number of rows returned in MySQL, you can use the following steps:

1. Write your SELECT query to retrieve data from the MySQL database. For example: SELECT * FROM your_table;
2. Execute the query using a MySQL client or interface.
3. After executing the query, you can use the mysql_affected_rows() function in PHP or the ROW_COUNT() function in MySQL to get the number of rows returned. Both functions return the number of rows affected by the last query. In PHP: $row_count = mysql_affected_rows(); In MySQL: SELECT ROW_COUNT(); This query will return the number of rows affected by the last query executed.
4. You can then use the obtained row count value as required in your application logic or display it to the user.

How to get the number of rows returned by a MySQL query using Laravel ORM?

To get the number of rows returned by a MySQL query using Laravel's ORM, you can use the count() method. Here's an example:

1
2
3

5

use App\Models\User; // Import the model you want to query

$count = User::where('status', 'active')->count();

echo $count; // Output the number of rows returned

In this example, we are using the User model and getting the count of all active users. The count() method will execute the query and return the number of rows returned.

You can also chain additional query methods before calling count() to filter the query further. For example:

1
2
3

$count = User::where('status', 'active')
             ->where('role', 'admin')
             ->count();

This will only count the number of rows where the status is active and the role is admin.
