dtenedor opened a new pull request, #40996: URL: https://github.com/apache/spark/pull/40996
### What changes were proposed in this pull request? This PR updates column DEFAULT assignment to add missing values for MERGE INSERT actions. This brings the behavior to parity with non-MERGE INSERT commands. It also adds a small convenience feature where if the provided default value is a literal of a wider type than the target column, but the literal value fits within the narrower type, just coerce it for convenience. For example, `CREATE TABLE t (col INT DEFAULT 42L)` returns an error before this PR because `42L` has a long integer type which is wider than `col`, but after this PR we just coerce it to `42` since the value fits within the short integer range. ### Why are the changes needed? These changes make column DEFAULT values more usable in more types of situations. ### Does this PR introduce _any_ user-facing change? Yes, see above. ### How was this patch tested? This PR adds new unit test coverage. -- This is an automated message from the Apache Git Service.
