Join tables

Join tables

I have 2 tables, customers and quotes. I have joined the customers table with my quote table. Below is the query that I am using.

SELECT quotes.quoteID, quotes.customerID, customers.customerName
FROM quotes
LEFT OUTER JOIN customers ON quotes.customerID = customers.customerID

I get the following error "Column 'customerID' in where clause is ambiguous" when I searched by either customer ID or customer name. I tried using Includes, Begin with, and = from dataAssist wizard when creating the search form.

I am only getting the error when I used the LEFT OUTER JOIN clause.

the data assist search code will need to be edited to clarify the table names.


for example, change line 25 of the results page:

php:
$WADbSearch1->addComparisonFromEdit("customerID","S_customerID","AND","Begins With",1);




to:

php:
$WADbSearch1->addComparisonFromEdit("quotes.customerID","S_customerID","AND","Begins With",1);

Error is gone but...

is there a way to search with either customer ID or name? I get results when I entered customer ID but I get zero results when I entered the customer name. I changed the "Begin with" to "Includes".

Thanks for fixing the error message.

I just need to know if it can be done with join tables

Is it possible for dataAssit to create a search page to search either by customer ID or customer NAME? I have joint customer table to quote table.

Customer Table
customerID (primary key)
customerName


Quote Table
quoteID (primary key)
customerID (foreign key)

QUERY
---------------
SELECT quotes.quoteID, quotes.customerID, customers.customerName
FROM quotes
LEFT OUTER JOIN customers ON (quotes.customerID = customers.customerID)

Can you please point me in the right direction where I can make the adjustment.

you would need to edit the data assist search and add a parameter to use the customer name column, current;y you only have a parameter for the customer ID column and none for the customer name column.


the wizard wont do this for you automaticly, you need to edit the behavior after the search is created.

Sorry to bother you again

Do you mean create a parameter like this

Customer ID parameter
------------------------ $WADbSearch1->addComparisonFromEdit("quotes.customerID","S_customerID","AND","Includes",0);


Customer Name parameter
-------------------------- $WADbSearch1->addComparisonFromEdit("customers.customerName","S_customerID","AND","Includes",0);

Please let me know if this is right, if not then I just live with search by customer ID only.

you should create a new form element for the costomer name on the search form, and use that in the perameter:

say the new form element is named "S _customerName":

php:
$WADbSearch1->addComparisonFromEdit("customers.customerName","S _customerName","AND","Includes",0);
