Json support? [DATAJDBC-284]

[spring-projects-issues]

srinivas kvs opened DATAJDBC-284 and commented

Add an attribute to @Embed introduced in DATAJDBC-111 so that the annotated property gets stored as JSON instead of multiple embedded columns.

The attribute should not be boolean but an enum since we might want to support other formats in the future, e.g. XML

I'm currently not sure how such support would look like. Could you be a little more specific what you would like to see?

Think if we could somehow define a ColumnType to mark it as Json Type, then behind the scene when you are actually generating the insert/ update statement to map the values to columns you could do something like   

cast(:additionalParams as JSON)

 

This is probably very postgres syntax

So if we frame the goal Postgres independently you are looking for for a way to make generated SQL dependent on the "type" of the attribute that represents that column in the object model. "Type" being used in a very broad sense here.

This does sound useful, but also very specialized. I'll leave the issue open but to be honest it is well down on the priorities list

When will this feature be released? I can't wait 😃

Almost all of the today's RDBMS have JSON datatype, it should be possible to make it RDBMS independent (or at least converters could be implemented for different RDBMSes).

It should be the easiest to add JSON function to Criteria API.
