/**
* This type is used for the {@link Insert}'s DSL API.
*
* Example:
* DSLContext create = DSL.using(configuration);
*
* TableRecord record =
* create.insertInto(table, field1, field2)
* .values(value1, value2)
* .returning(field1)
* .fetchOne();
*
* This implemented differently for every dialect:
*
* - Firebird and Postgres have native support for
*
INSERT .. RETURNING clauses
* - HSQLDB, Oracle, and DB2 JDBC drivers allow for retrieving any table
* column as "generated key" in one statement
* - Derby, H2, Ingres, MySQL, SQL Server only allow for retrieving IDENTITY
* column values as "generated key". If other fields are requested, a second
* statement is issued. Client code must assure transactional integrity between
* the two statements.
* - Sybase and SQLite allow for retrieving IDENTITY values as
*
@@identity or last_inserted_rowid() values. Those
* values are fetched in a separate SELECT statement. If other
* fields are requested, another statement is issued. Client code must assure
* transactional integrity between these statements.
