🛠 Usage

Basic Query Example

SELECT id, name FROM products WHERE category = :category

• Parameter example:
  • category = "Electronics"

Using Parameters

You can pass dynamic values using named parameters:

Using IN Operator

When using IN, the node expands values dynamically:

SELECT id, name FROM products WHERE category IN (:categories)

• Parameter example:
  • categories = "Electronics, Home, Clothing"

This is automatically converted into:

SELECT id, name FROM products WHERE category IN (:param1, :param2, :param3)

• Making it safe and preventing SQL injection.
