  • 0

Okay so I’m getting to the next stage with JQuery and I’ve used AutoComplete a few times with success but only using 1 table from MYSQL. Now I’m using it and trying to do a JOIN query with it. The MYSQL query works fine when I change LIKE :term to = 1 (A customer number for example.) in MYSQL but when I try the Query below I dont get anything, not errors just nothing. Any suggestions?

    i think that the reason you don’t get any results is because that you have an error in your query (duplicate ‘Customer_ID’ field), try this one:

    $query = "SELECT
    Customers.Customer_ID,
    Customers.CompanyName,
    CustomerDetails.Discount,
    CustomerNotes.CustNotes,
    CONCAT_WS(' ', Customers.Customer_ID, Customers.CompanyName, CustomerDetails.Discount, CustomerNotes.CustNotes) AS DisplayName
FROM Customers
JOIN CustomerDetails USING (`Customer_ID`)
JOIN CustomerNotes USING (`Customer_ID`)
WHERE Customers.Customer_ID LIKE :term
    OR Customers.CompanyName LIKE :term
    OR CustomerDetails.Discount LIKE :term
    OR CustomerNotes.CustNotes LIKE :term
    ";
