Deprecated

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

DB2's substring() function requires a code unit and substr() can't optionally take it, so we render substr() by default. If the code unit is passed, we render substring().
