Question

Users Screenshot users table

field_data_field_user_first_name screenshot fields table

What query should I use to get a table like this:

Uid  Email         First name

1    123@123.com   example 

I have tried without luck:

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

Answer 1

You will get same result as mentioned above by using this query

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;
