Frends.ODBC.ExecuteQuery / 4.0.0
Summary
Runs SQL through an ODBC driver, which makes it the route to databases with no dedicated Frends Task. Parameters are positional, as ODBC itself requires.
Typical use — legacy and niche databases; prefer the dedicated Task where one exists, since it will handle types more faithfully
