Unable to skip column using JSONPropertyOrder

Unable to skip column in csv using JSONPropertyOrder
My use case is to load few speicfic columns, also needs to skip most of the columns

[cowtowncoder]

I don't understand: skip? How would @JSONPropertyOrder help? CSV is positional so you must specify all columns the precede ones you need; there's no way around that.

You can, if that helps, just bind rows as String[] (or List<String>), and then extract positions you care about.

But I can specific column number using @JsonProperty("6") something like
this for csv then I do not have create schema separately before calling
mapper.read

@shankyty No. Properties are specified by name with that notation, and having JSON property name like "6" is completely legal (even if unlikely).

However, there is index:

@JsonProperty(index=6)

which could conceivably allow doing this. So... perhaps something like this could be done, theoretically speaking, if anyone wanted to work on this.

I could modify the title, or create a new issue, for this idea.

Reply I can work on this since I need it and I think it would cleaner
approach for me too.
