I want to store Mathematica results in an external rdbms, Postgres specifically.
The Mathematica documentation talks a lot (eg in 'Relational Database Quick Start') about extracting data from external databases but very little (to nothing?) that I can see about using external relational databases to store information.
It seems to me that to use something like
ExternalEvaluate[ dbConnection, "INSERT INTO tbl(col1, col2) VALUES "<> calculated_values_as_strings ]
is very rough and potentially unsafe.
With Mathematica V12's new
EntityStore objects there must be a nicer way to store data in an external RDBS. How is it done?
DatabaseLink the only solution?
