JPA concat operator

Question

Is there a JPA concat operator for string concatenation?

I know there is a JPA CONCAT function, however its ugly to use for concatenating multiple strin

Answer 1

The CONCAT function was extended in JPA 2.0 to allow passing more than 2 parameters, from section 4.6.17.2.1 (String Functions) of the specification:

CONCAT(string_primary, string_primary {, string_primary}* )

In JPA 1 this was restricted to exactly two parameters.
