Class FBRowUpdater
java.lang.Object
org.firebirdsql.jdbc.FBRowUpdater
public class FBRowUpdater
- extends java.lang.Object
Class responsible for modifying updatable result sets.
A result set is updatable if and only if:
- It is a subset of a single table and includes all columns from the
table's primary key (in other words, includes all best row identifiers) or
RDB$DB_KEY column (in this case tables without primary key can be updated
too).
- If base table columns not included in the result set allow NULL values,
result set allows inserting rows into it.
- The result set's SELECT statement does not contain subqueries, a
DISTINCT predicate, a HAVING clause, aggregate functions, joined tables,
user-defined functions, or stored procedures.
If the result set definition does not meet these conditions, it is considered
read-only.
