⚠️ @FishermanZzhang Your base branch master has just also updated superset/migrations.

❗ Please consider rebasing your branch to avoid db migration conflicts.

@FishermanZzhang, sadly this wont work as every database encodes uniqueness with NULL differently.

In my opinion. SQLALCHEMY_DATABASE_URI = 'mysql://{user}:{passwd}@{host}/superset is best.

Can you give context on why we'd want to add this constraint?

Also, this model is going away soon, see SIP-68 (#14909). The new model separates tables (which will have a uniqueness constraint) from datasets (which can point to the same table).

Closing this, since #14909 will replace it.
