Question

I'm working with Spring boot and mssql, but there is a performance problem in spring's jdbctemplate where it searches to discover the type of the field when null is entered as a parameter and this greatly worsens the application's performance and I want to disable this behavior , but I need to know if the mssql driver always expects a type to be informed when passing a null value, or if reporting a null without a type is something fully supported, I know that the problem is not from this repository, but I couldn't find any document that says whether or not the driver supports untyped null arguments.

Link to the jdbctemplate issue if the issue was not well explained: spring-projects/spring-framework#25679 (Although the issue talks about postgresql the same problem occurs in mssql).
