All Implemented Interfaces:

java.io.Serializable

public class TooManyRowsException
extends InvalidResultException

Too many rows (more than 1) were returned from a ResultQuery.

Like any other InvalidResultException, this exception indicates to clients that the result was not what they expected, but this does not have any effect on the outcome of the statement producing that result. For instance, if calling ResultQuery.fetchOne() on a SELECT .. FOR UPDATE query, or InsertResultStep.fetchOne() on an INSERT statement, the database change will still be executed: the rows will still be locked or inserted.

Performance

Methods throwing TooManyRowsException need to retrieve at most two records from the underlying JDBC ResultSet, which, depending on the Statement.getFetchSize() / ResultQuery.fetchSize(int), might incur additional database roundtrips. If this causes problems, ResultQuery.fetchAny() may be preferred.
