Repair incorrectly merged mariadb logic

The changeset in c88d4d0 takes advantage of a
mariadb function that got randomly committed as part
of the SQL server fixup in 2efd89d02941ab4267d6e2842963, not
part of rel_1_1.    The change here was not reviewed or tested
in gerrit and breaks the main branch.

Change-Id: I41746f890e6e82acfb12e78f174d00d7ba7d19d4
Fixes: #4097
