@codezero00 hi, Thank you for raising this issue.
Does this mean that the view's field type failed to preserve the NOT NULL property from the base table(s)?
The results show column c in view v as NOT NULL (Null: NO, is_nullable: NO), matching the base table t. I might miss-understand your question though. Please let us know if we should test with other scenarios. Best regards. |

Currently, databend supports the mysql protocol, which is great. However, I have discovered a problem: the field type of the view in databend is NULL, and the default binary(0) is not provided. In other databases, there is no situation where the field type is NULL. This will cause many existing software that are compatible with the mysql protocol to be unable to read the metadata of databend and report an error
