Question

I’m having a difficult time do the following with the JPA CriteriaBuilder:

SUBSTRING( field, LENGTH( field ) - 7 )

The database I am using does not have a RIGHT function, if it did I could just do the following:

builder.function( "RIGHT", String.class, fieldExp, builder.literal(7) );

But no dice. While CriteriaBuilder DOES have a substring function expression I cannot figure out how to do the substraction from LENGTH for the literal 7.

Any thoughts? TIA

Alright, got it.

builder = builder.substring( field, builder.diff( builder.length( field ), 7 );
