Execute Query & Get Results

This flow shows how Laravel builds a query by adding where, orWhere, and advanced conditions step-by-step before executing.

Execution Sample

Laravel

$query = DB::table('users')
    ->where('status', 'active')
    ->orWhere(function($q) {
        $q->where('age', '>', 30)
          ->where('role', 'admin');
    })
    ->get();

This code builds a query selecting users who are active OR who are older than 30 AND have the admin role.

Execution Table

Step	Action	Condition Added	Query State	Notes
1	Start Query Builder	None	SELECT * FROM users	Initial query on users table
2	Add where	status = 'active'	SELECT * FROM users WHERE status = 'active'	First condition added
3	Add orWhere with closure	OR (age > 30 AND role = 'admin')	SELECT * FROM users WHERE status = 'active' OR (age > 30 AND role = 'admin')	Advanced grouped conditions added
4	Execute get()	N/A	Query executed, results fetched	Final step, query runs

💡 Query executed after adding where and orWhere conditions with closure grouping

Variable Tracker

Variable	Start	After Step 2	After Step 3	Final
$query	DB::table('users')	Added where status='active'	Added orWhere closure with age>30 and role='admin'	Query ready to execute

Key Moments - 2 Insights

Why do we use a closure inside orWhere?

Using a closure groups multiple conditions together inside parentheses, so Laravel builds SQL like OR (cond1 AND cond2). See execution_table step 3 for how conditions are grouped.

Does orWhere replace the previous where condition?

No, orWhere adds an alternative condition combined with OR. The previous where stays. The query becomes WHERE cond1 OR cond2, as shown in execution_table steps 2 and 3.

Visual Quiz - 3 Questions

Look at the execution_table at step 3, what SQL condition is added?

A AND (age > 30 OR role = 'admin')

B OR (age > 30 AND role = 'admin')

C WHERE age > 30 AND role = 'admin'

D OR age > 30 OR role = 'admin'

💡 Hint

Check the 'Condition Added' column at step 3 in execution_table

At which step does the query builder add the first condition?

A Step 2

B Step 1

C Step 3

D Step 4

💡 Hint

Look at the 'Action' and 'Condition Added' columns in execution_table

If we remove the closure and add two orWhere calls separately, how would the query change?

A It would be WHERE status='active' OR (age>30 AND role='admin')

B It would be WHERE status='active' AND age>30 AND role='admin'

C It would be WHERE status='active' OR age>30 OR role='admin'

D It would be WHERE status='active' OR age>30 AND role='admin'

💡 Hint

Closure groups conditions with AND inside OR; separate orWhere calls add OR conditions separately

Concept Snapshot

Laravel orWhere adds alternative conditions to queries.
Use closures in orWhere to group multiple conditions.
Without closure, orWhere adds single OR conditions.
This builds SQL like: WHERE cond1 OR (cond2 AND cond3).
Advanced conditions help build complex queries simply.

Full Transcript

This visual execution shows how Laravel's query builder adds where and orWhere conditions step-by-step. First, it starts with the users table. Then it adds a where condition for status='active'. Next, it adds an orWhere condition using a closure to group age>30 and role='admin' together. This creates a SQL query selecting users who are active or who are older than 30 and admins. The variable $query changes as conditions are added. Key points include that orWhere adds alternative conditions without replacing previous ones, and closures group multiple conditions inside parentheses. The execution table traces each step, showing how the SQL query builds up before execution.
