Examples of DbSqlBuilder

jodd.db.oom.sqlgen.DbSqlBuilder
Nice SQL query generator that provides some automatic query generation.
Query is built by appending 'chunks' - parts of the query. These chunks may be very simple, as a simple string. However, the main reason of existence of this class are chunks that auto-generate part of the query based on provided domain object. They can be used to easily create some most common queries in an efficient way.
Although it is not necessary, use of {@link jodd.db.oom.meta.DbId} annotation boost the functionalityof this query builder.
Some chunks deals with relations between tables, so they must be aware of foreign key names. Here the naming convention is used, and even users might have their own foreign key naming convention.
Furthermore, if all queries are generated using just sql builder, it is possible to use dialects for various database types.
