Ability to change default sql type mappings [DATAJDBC-526]

[spring-projects-issues]

Alexander Gladskoy opened DATAJDBC-526 and commented

Please provide ability to bind parameter to non-default sql-type. For example I have this code

@Query("update someTable set stringAttr = :stringAttr where id = :id")
int updateString(@Param("id") long id, @Param("stringAttr") String stringAttr);

And I want the parameter stringAttr to be binded to NVARCHAR instead of default VARCHAR

Use this setting sendStringParametersAsUnicode=true

in yml,

append to the datasource url : jdbc

or in 

tomcat "connection-properties:"

This should be possible once we have SpEL support: DATAJDBC-397

I would like to ask, the reverse, I have just upgraded to  Spring Boot 2.3.2, and I want to to prevent binding to NVARCHAR and instead use the of default VARCHAR. We have no Unicode in out system and NVARCHAR is suddenly drastically affecting performance. 

This setting that used to work now does not work after the upgrade:  sendStringParametersAsUnicode=false

Can you shed some light on this?
