Deprecated

as a consequence of AbstractSqmSelfRenderingFunctionDescriptor being deprecated. See corresponding docs for further information.

ANSI SQL-standard trim() function, which has a funny syntax involving a TrimSpec, and portability is achieved using Dialect#trimPattern(TrimSpec, boolean).

For example, trim(leading ' ' from text).
