Annotation for sql type [DATAJDBC-239]

[spring-projects-issues]

Jens Schauder opened DATAJDBC-239 and commented

We need a way to specify the java.sql.Types value to be used for binding parameters.

This applies to

• columns/properties
• converters
• method parameters

The idea is to have a single annotation that can be used in all these places

When this is implemented for converters it should solve DATAJDBC-148

Jens Schauder commented

The converters part is currently getting implemented by DATAJDBC-327

Johannes Edmeier commented

Without this feature it's also currently not possible to use custom value types as Ids for aggregates with nested entities.
Reason: org.springframework.data.jdbc.core.convert.DefaultDataAccessStrategy.findAllByPath() uses the id as query parameters, which currently don't get converted

Johannes Edmeier is this still the case for the master branch (1.1 milestone) if so please create a separate issue for this

It currently doesn't look like this is needed
