Cast ld values to varchar in user artifacts statement

    The problem appears to be that now with v in the artifactsdb as
    a TEXT datatype that we get CLOBS as a result here. To make
    the old stuff work we cast the ld_ values that are evalutated
    in datacage functions back to varchar and thus to strings.

+            XXX: The cast is a quick hack because the ld_* values are
+            now TEXT fields. To properly fix / asses the problems here
+            an SLT evaluation is needed.
