CannotAcquireLockException

Exception thrown on failure to aquire a lock during an update, for example during a "select for update" statement.

CannotSerializeTransactionException

Exception thrown on failure to complete a transaction in serialized mode due to update conflicts.

CleanupFailureDataAccessException

Exception thrown when we couldn't cleanup after a data access operation, but the actual operation went OK.

For example, this exception or a subclass might be thrown if a JDBC Connection couldn't be closed after it had been used successfully.

Note that data access code might perform resources cleanup in a finally block and therefore log cleanup failure rather than rethrow it, to keep the original data access exception, if any.

DuplicateKeyException

Exception thrown when an attempt to insert or update data results in violation of an primary key or unique constraint. Note that this is not necessarily a purely relational concept; unique primary keys are required by most database types.

EmptyResultDataAccessException

Data access exception thrown when a result was expected to have at least one row (or element) but zero rows (or elements) were actually returned.

QueryTimeoutException

Exception to be thrown on a query timeout. This could have different causes depending on the database API in use but most likely thrown after the database interrupts or stops the processing of a query before it has completed.

This exception can be thrown by user code trapping the native database exception or by exception translation.

TransientDataAccessResourceException

Data access exception thrown when a resource fails temporarily and the operation can be retried.

TypeMismatchDataAccessException

Exception thrown on mismatch between Java type and database type: for example on an attempt to set an object of the wrong type in an RDBMS column.
