BadSqlGrammarException	Exception thrown when SQL specified is invalid.
CannotAcquireLockException	Exception thrown on failure to aquire a lock during an update, for example during a "select for update" statement.
CannotCreateRecordException	Exception thrown when the creating of a CCI Record failed for connector-internal reasons.
CannotGetCciConnectionException	Fatal exception thrown when we can't connect to an EIS using CCI.
CannotGetJdbcConnectionException	Fatal exception thrown when we can't connect to an RDBMS using JDBC.
CannotSerializeTransactionException	Exception thrown on failure to complete a transaction in serialized mode due to update conflicts.
CciOperationNotSupportedException	Exception thrown when the connector doesn't support a specific CCI operation.
CleanupFailureDataAccessException	Exception thrown when we couldn't cleanup after a data access operation, but the actual operation went OK.
ConcurrencyFailureException	Exception thrown on concurrency failure.
DataAccessResourceFailureException	Data access exception thrown when a resource fails completely: for example, if we can't connect to a database using JDBC.
DataIntegrityViolationException	Exception thrown when an attempt to insert or update data results in violation of an integrity constraint.
DataRetrievalFailureException	Exception thrown if certain expected data could not be retrieved, e.g.
DataSourceLookupFailureException	Exception to be thrown by a DataSourceLookup implementation, indicating that the specified DataSource could not be obtained.
DeadlockLoserDataAccessException	Generic exception thrown when the current process was a deadlock loser, and its transaction rolled back.
DuplicateKeyException	Exception thrown when an attempt to insert or update data results in violation of an primary key or unique constraint.
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.
HibernateJdbcException	Hibernate-specific subclass of UncategorizedDataAccessException, for JDBC exceptions that Hibernate wrapped.
HibernateObjectRetrievalFailureException	Hibernate-specific subclass of ObjectRetrievalFailureException.
HibernateOptimisticLockingFailureException	Hibernate-specific subclass of ObjectOptimisticLockingFailureException.
HibernateQueryException	Hibernate-specific subclass of InvalidDataAccessResourceUsageException, thrown on invalid HQL query syntax.
HibernateSystemException	Hibernate-specific subclass of UncategorizedDataAccessException, for Hibernate system errors that do not match any concrete `org.springframework.dao` exceptions.
IncorrectResultSetColumnCountException	Data access exception thrown when a result set did not have the correct column count, for example when expecting a single column but getting 0 or more than 1 columns.
IncorrectResultSizeDataAccessException	Data access exception thrown when a result was not of the expected size, for example when expecting a single row but getting 0 or more than 1 rows.
IncorrectUpdateSemanticsDataAccessException	Data access exception thrown when something unintended appears to have happened with an update, but the transaction hasn't already been rolled back.
InvalidDataAccessApiUsageException	Exception thrown on incorrect usage of the API, such as failing to "compile" a query object that needed compilation before execution.
InvalidDataAccessResourceUsageException	Root for exceptions thrown when we use a data access resource incorrectly.
InvalidResultSetAccessException	Exception thrown when a ResultSet has been accessed in an invalid fashion.
JdbcUpdateAffectedIncorrectNumberOfRowsException	Exception thrown when a JDBC update affects an unexpected number of rows.
JdoObjectRetrievalFailureException	JDO-specific subclass of ObjectRetrievalFailureException.
JdoOptimisticLockingFailureException	JDO-specific subclass of ObjectOptimisticLockingFailureException.
JdoResourceFailureException	JDO-specific subclass of DataAccessResourceFailureException.
JdoSystemException	JDO-specific subclass of UncategorizedDataAccessException, for JDO system errors that do not match any concrete `org.springframework.dao` exceptions.
JdoUsageException	JDO-specific subclass of InvalidDataAccessApiUsageException.
JpaObjectRetrievalFailureException	JPA-specific subclass of ObjectRetrievalFailureException.
JpaOptimisticLockingFailureException	JPA-specific subclass of ObjectOptimisticLockingFailureException.
JpaSystemException	JPA-specific subclass of UncategorizedDataAccessException, for JPA system errors that do not match any concrete `org.springframework.dao` exceptions.
LobRetrievalFailureException	Exception to be thrown when a LOB could not be retrieved.
NonTransientDataAccessResourceException	Data access exception thrown when a resource fails completely and the failure is permanent.
ObjectOptimisticLockingFailureException	Exception thrown on an optimistic locking violation for a mapped object.
ObjectRetrievalFailureException	Exception thrown if a mapped object could not be retrieved via its identifier.
OptimisticLockingFailureException	Exception thrown on an optimistic locking violation.
PermissionDeniedDataAccessException	Exception thrown when the underlying resource denied a permission to access a specific element, such as a specific database table.
PessimisticLockingFailureException	Exception thrown on a pessimistic locking violation.
RecordTypeNotSupportedException	Exception thrown when the creating of a CCI Record failed because the connector doesn't support the desired CCI Record type.
SQLWarningException	Exception thrown when we're not ignoring java.sql.SQLWarning SQLWarnings.
SqlXmlFeatureNotImplementedException	Exception thrown when the underlying implementation does not support the requested feature of the API.
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.
UncategorizedDataAccessException	Normal superclass when we can't distinguish anything more specific than "something went wrong with the underlying resource": for example, a SQLException from JDBC we can't pinpoint more precisely.
UncategorizedSQLException	Exception thrown when we can't classify a SQLException into one of our generic data access exceptions.

Class Overview

Root of the hierarchy of data access exceptions discussed in Expert One-On-One J2EE Design and Development. Please see Chapter 9 of this book for detailed discussion of the motivation for this package.

This exception hierarchy aims to let user code find and handle the kind of error encountered without knowing the details of the particular data access API in use (e.g. JDBC). Thus it is possible to react to an optimistic locking failure without knowing that JDBC is being used.

As this class is a runtime exception, there is no need for user code to catch it or subclasses if any error is to be considered fatal (the usual case).
