EJB QL LIKE operator

Hello,

I want to perform search by keyword on all fields of a table. Say I have a product table with following fields:

Field Name Data Type
ProductNo Integer
ProductName String
Brand String
UnitPrice Double
SupCode Integer

I cannot use LIKE operator as follows:
“SELECT OBJECT(p) FROM Product AS p WHERE p.productName LIKE ?1 or p.supCode LIKE ?1 or p.partNo LIKE ?1 p.brand LIKE ?1 or p.unitPrice LIKE ?1 ORDER BY p.productName ASC”

This throws error as LIKE operator expects String fields only. Is there any way I can use LIKE operator or any other way to search by keywords on all field of any data type using EJB QL.
