This `Null___` type is a struct that wraps the enum's string alias type and adds a `Valid` boolean property to represent the `NULL` state.\r\n\r\nsqlc has a setting called `emit_pointers_for_null_types` which replaces similar nullable wrapper types with pointers instead (`NullString` -\u003e `*string`)\r\n\r\nThis feature request seeks to bring similar functionality to nullable enum fields. Instead of generating a `Null___` type for a nullable enum field, it should be a represented by a pointer (`NullFooEnum` -\u003e `*FooEnum`)\r\n\r\n### Questions\r\n\r\n- If this feature were to be implemented, should it be enabled by the existing `emit_pointers_for_null_types` config setting? Or should it be a separate setting?\r\n\r\n### Other notes\r\n\r\nI couldn't find an existing issue for this, but there is an open PR #3093 which seemed to be working towards the same goal.\r\n\r\n### What database engines need to be changed?\r\n\r\n_No response_\r\n\r\n### What programming language backends need to be changed?\r\n\r\n_No response_","author":{"url":"https://github.com/nderscore","@type":"Person","name":"nderscore"},"datePublished":"2024-03-15T18:10:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/3276/sqlc/issues/3276"}
