php - get product price based on customer code -


my product table looks 

id     type          product code     product name     price 1      customers 56620000         product        219.68 € 2      customers 56621000         product b        4,351.91 € 3      customers 56622000         product c        110.98 € 4      155000        56622000         product c        100.00 € 5      customers 56626000         product d        2,410.38 € 6      customers 56772000         product e        100.00 € 7      160000        56772000         product e        90.00 €

if notice row 3,4 , 6,7 has same product code different type , price. means product can have price customer few specific customers. if customer customer id 155000 performs search product code 56622000, customer price 100.00 € (see row number 4) not 110.98 € (see row number 3). if same customer performs search product code 56772000, he/she price 100.00 €(see row number 6) not 90.00 €(see row number 7). because there no specific price user product code 56772000.

my query: how execute operation using php , mysql single table.?

select  *    product   productcode = 'x' ,         type in ('y', 'all customers') order   field(type, 'y', 'all customers') limit   1

replace x , y desired value shown in demo.
