In SQL databases, you have the Like operator. In OCL, we added this same functionality as SqlLike.

SqlLike works both in OCL and in OCL-PS.

SqlLike enables you to match part of strings like this:

Person.allinstances->select(a|a.Identity.sqlLike('%'+vSeekParam+'%'))->orderby(identity)

Add a % to say that "it could be anything here."
