示例2: GetAttributeSelectSql

// GetAttributeSelectSql generates the select query to retrieve full attribute configuration
// Implements the scope on a SQL query basis so that attribute functions does not need to deal with it.
// Tests see the tools package
// @see magento2/app/code/Magento/Eav/Model/Resource/Attribute/Collection.php::_initSelect()
