How to use multiple OR,AND condition in Laravel queries

Title: Mastering Multiple OR/AND Conditions in Laravel Queries Introduction: Laravel is an incredibly powerful framework for building web applications, allowing developers to leverage its advanced query builder functionality with ease. In this blog post, we will delve into the intricacies of using multiple OR and AND conditions in Laravel queries and provide you with a comprehensive guide on how to get the desired results. 1. Understanding Query Conditions First off, it is essential to understand the difference between logical operators (OR and AND) and their usage in database queries. An 'AND' operator matches all specified conditions concurrently, whereas an 'OR' operator returns records if any of the conditions are met. A combination of these operators can result in complex query conditions. 2. Query Conditions using Eloquent Builder Laravel provides a clean and expressive interface to manage database interactions through its eloquent model. The Eloquent model allows you to create, read, update, and delete data from your database in a more straightforward manner. To achieve this, we can employ the where() method on our query builder instance:

Event::where('status' , 0) -> where("type" , "private") -> orWhere('type' , "public") -> get();

In this code snippet, we first filter out events with a status of 0. Then, we add an additional condition to find only the events with their type either as "private" (using where) or "public" (using orWhere). The get() method executes our query and returns all matching records. 3. Properly Handling Multiple Conditions As discussed earlier, your code currently seems to return public events that have a status of 0 as well. To correct this behavior, we can restructure the query by moving the condition related to the event's type first:

Event::where("type" , "private") -> orWhere('type' , "public") -> where('status' , 0) -> get();

Reordering the conditions in this manner ensures that we first check for events with a specific type (either private or public). Only then do we verify whether these events have a status of 0. 4. Query Conditions using Raw SQL While Laravel's Eloquent model offers an excellent interface for database interactions, you may occasionally need to write custom SQL statements. In such cases, you can use the DB facade to execute raw queries:

DB::select('Select * FROM events WHERE status = 0 AND (type="public" or type = "private")');
