What are the differences between the SQL dialect implementations called then? Extensions?
- dragonwriter 7y agoThey are called either pieces of the standard one or the other hasn't implemented or extensions, depending on which they are, sure. This is pretty explicit in the Postgres docs which directly address standards compliance throughout the SQL reference and specifically address bits of the standard they don't support or Postgres extensions to the standard. Oracle, IIRC, doesn't talk about it as directly in the main docs (though it's been longer since I read Oracle docs.)
