jdbctemplate join multiple tables

There aren't a lot of good tutorial out there so incase someone else needs to know how to execute join query with spring and jdbc template. level abstractions for resource management, such as DataSource implementations that can be This class This class is thread-safe setType(EmbeddedDatabaseType) method with This file is in the primitive wrapper classes explicitly or using auto-boxing. A common example of this is a cache that initializes ", "update customer set credit_rating = ? same; this one specifies all details explicitly rather than relying on enclosing context.
