查詢附加到實體在SQL Drupal數據庫中的字段

Question

用戶 Screenshot users table

field_data_field_user_first_name screenshot fields table

我應該使用什麼樣的查詢來獲取這樣的表格：

Uid Email   First name 

1 123@123.com example 

我曾嘗試沒有運氣：

SELECT * FROM users 
LEFT JOIN field_data_field_user_first_name 
ON users.uid = ield_data_field_user_first_name.entity_id 

Answer 1

如上通過使用此查詢

SELECT users.uid as Uid,users.mail as Email,field_data_field_user_first_name.field_user_first_name_value as FirstName FROM users 
LEFT JOIN field_data_field_user_first_name 
ON users.uid = ield_data_field_user_first_name.entity_id;
