    Class SQLExpressionValidator

    Central SQL expression validator for preventing SQL injection.

    Provides context-aware validation for different types of SQL expressions (WHERE clauses, ORDER BY, aggregates, etc.) with detailed error reporting.

    const validator = SQLExpressionValidator.Instance;

    // Validate an aggregate expression
    const result = validator.validate('SUM(OrderTotal)', {
      context: 'aggregate',
      entityFields: ['OrderTotal', 'Quantity', 'Price']
    });

    if (!result.valid) {
      console.error(result.error);
    }

    Methods

    • The Global Object Store is a place to store global objects that need to be shared across the application. Depending on the execution environment, this could be the window object in a browser, or the global object in a node environment, or something else in other contexts. The key here is that in some cases static variables are not truly shared because it is possible that a given class might have copies of its code in multiple paths in a deployed application. This approach ensures that no matter how many code copies might exist, there is only one instance of the object in question by using the Global Object Store.

      Returns GlobalObjectStore | null

    • Returns the singleton instance of the class. If the instance does not exist, it is created and stored in the Global Object Store. If className is provided it will be used as part of the key in the Global Object Store, otherwise the actual class name will be used. NOTE: the class name used by default is the lowest level of the object hierarchy, so if you have a class that extends another class, the lowest level class name will be used.
