Language differences between 11gr2 and 19c Oracle Database versions

in SQL Language (MOSC) 4 commentsAnswered ✓

Hello, in the next months we would like to upgrade our 2 Oracle instances from 11gr2 (our current version) to 19c version.

I would like to understand clearly which are the differences in SQL language in these 2 versions.

E.g., are there some SQL functions that have been deprecated from 11gr2 to 19c?

Do some syntaxes have changed?

Do some statements have changed or do they have some new features?


Is there a document where i can check this?


Best regards,

Sara
