What does it mean to be interoperable in ODBC?
Interoperability is the ability of a single application to operate with many different DBMSs. The need to write generic, interoperable applications was one of the major factors leading to the development of ODBC. However, interoperability is not a simple path followed from “not interoperable” to “completely interoperable.”
Which is an example of database compatibility mode 150?
SQL Server 2019 is adding even more performance improvements and behavior changes that are enabled by default when a database is using compatibility mode 150. A prime example is scalar UDF inlining, which automatically inline many scalar UDF functions in your user databases.
