RESTRICT is a referential action in its own right.ReferentialAction.Restrict is parsed, written and rendered.
SqlDialect.SupportsRestrict says whether the engine has RESTRICT as distinct from NO ACTION. Providers have to opt in.
A generated column records whether it is stored.Column.IsStored and the NSQL STORED / VIRTUAL keywords.
SqlDialect.SupportsVirtualGeneratedColumns says whether the engine can leave one unstored. Off by default, matching Postgres, which stores every generated column.
virtual-generated-column-not-supported is a warning: a virtual generated column declared against an engine that always stores.
A column records whether it is the table’s row identifier for merge replication.Column.IsRowGuid and the NSQL ROWGUIDCOL keyword.
A column default can carry its constraint’s name.Column.DefaultConstraintName and the NSQL CONSTRAINT <name> DEFAULT <expr> form, for engines that make a default a named constraint.
An identity and a trigger can stand aside for a replication agent.IdentityOptions.NotForReplication, Trigger.IsNotForReplication, and the NSQL NOT FOR REPLICATION form on both.
DiagnosticSources declares every source the engine reports under, and DiagnosticSources.All offers them to a caller checking a configured name against the sources that exist.
Changed
Diagnostic sources and codes are a configuration contract, so this release settles their naming before the next CLI makes them addressable from .editorconfig.
Fixed
Trigger.Clone(), Equals and GetHashCode cover every field, as Column’s now do. Both enumerate fields by hand, and import clones every object on its way to a file.
