> SQL {{SUBSTRING}} function indexes strings from 1, but OData {{substring}} filtering function indexes from zero. This needs to be taken into account.
> Currently a query containing {{WHERE SUBSTRING(stringkey, 1, 1) = 'x'}} will return items where the second character is x, but it should return rows where the first character is x.
