In some SQL db you have to query explicitly the table schema, ie: ``select
data_type from all_tab_columns where table_name = 'my_table'``or something like
that.
In case of the ARQ engine from Apache Jena you can call this function in
SPARQL (see [W3C-SPARQL](https://www.w3.org/TR/rdf-sparql-query/#func-datatype).
I find it useful in order to avoid to query the schema.
