使用 Quickbooks ruby gem 如何 return 按 customer_ref 开具发票?

Using the Quickbooks ruby gem how do I return invoices by customer_ref?

我需要按customer_ref查询发票。我试过:

invoices = service.query("Select * From Invoice Where customer_ref = 75")

但那只是 returns:

Quickbooks::IntuitRequestException: Error parsing query:
QueryParserError: Encountered " <INTEGER> "75 "" at line 1, column 44.
Was expecting one of:
"false" ...
"true" ...
