Could also be that the standard is lacking in some areas. I'm not sql expert but I always end up using implementation specific features even for rather simple tasks. Are there really people out there sticking 100% to standard SQL? Hell, the biggest implementations don't even agree on whether table/column names are case sensitive
I don't think that explains it.
If we're talking about extensions that cover custom features then obviously those aren't supposed to be standardized because they haven't been widely adopted.
If an implementation is missing a feature then that's a shortcoming of that particular implementation, not SQL's.
If an implementation screws up and has non-compliance qwirks, that's a bug in the implementation, not a problem with SQL.
Take SQLite for example. It explicitly does not support static, rigid typing, and claims it's a feature. However, SQL supports static typing and other implementations leverage that for performance and cost gains. Additionally, SQLite also keeps a list with a summary of all the SQL features it purposely does not implement.
SQLite is pretty popular. Does this mean SQL is lacking in any way? Is the SQL standard "lacking" because it supports
ALTER TABLE foo ADD CONSTRAINT
even though SQLite does not? Or is this a problem caused by an implementation failing to comply with a standard?
