public record Join(Table table, List<Condition> conditions) extends Record
A database table join operation in a query.

This record encapsulates a target table and the conditions under which the join operation is performed. A join operation combines rows from the specified table with rows from another table, based on the provided conditions.

The target table is represented by the Table object, which may include metadata such as catalog, schema, and name. The conditions are represented as a list of Condition objects, each specifying a column, operator, and optional value.

This record is used in query-building to specify join operations within SQL select statements.
