Interface QueryMapper.MapperUpdateSetTo

Enclosing interface:
QueryMapper
public static interface QueryMapper.MapperUpdateSetTo
Represents the value assignment step of the update fluent API.

This step completes a field assignment started with set(String) by defining the value to be applied. After the value is assigned, the update query may define additional assignments, specify conditions, or be executed. 

@Inject
Template template;

template.update(Book.class)
    .set("title").to("Domain-Driven Design with Java")
    .set("publishedYear").to(2025)
    .where("author").eq("Ada")
    .execute();
The returned instance is mutable and not thread-safe. The behavior of the update operation depends on the capabilities of the underlying database.
