Hibernate Types

Back to Hibernate Tutorials Page

This section gives you description of all the Types that are supported by Hibernate. A Hibernate Type is used to map a Java property type to a JDBC type or types.

The following tables to represents all Hibernate types:

Interfaces and Descriptions:
AbstractComponentType	The AbstractComponentType enables other Component-like types to hold collections and have cascades, etc.
AssociationType	This interface used to represent all associations between entities.
DiscriminatorType	This interface used to discriminator properties with the help of right mapped subclass.
IdentifierType	This interface has All identifiers of entities.
LiteralType	This is a maker interface that which store SQL literals.
Type	This interface describes mapping between the Java and JDBC datatypes
VersionType	This interface used for version stamping.

Classes and Descriptions:
AbstractBynaryType	The stream of byte bounded into a VAQRBINARY.
AbstractCharArrayType	The stream of char bounded into a VARCHAR.
AbstractType	This is a superclass that can be used for creating type hierarchy.
AdaptedImmutableType
AnyType	It defines 'any' mappings and deprecated 'object' types.
AnyType.ObjectTypeCacheEntry
ArrayType	It represents collection of data into a similar types.
BagType
BigDecimaType	This class used to mapping between SQL NUMERIC and java.math.BigDecimal.
BigIntegerType	This class used to mapping between SQL NUMERIC and java.math.BigInteger.
BinaryType	It used to mapping between a SQL VARBINARY and a Java byte[].
BlobType	It used to mapping between a SQL BLOB and java.sql.Blob.
BooleanType	This class maps between SQL BIT and Java Boolean.
ByteType	This class maps between SQL TINYINT and Java Byte.
CalendarDateType	This class represents a data and mapping into a Calendar object.
CalendarType	It also represents a datetime mapping into a Calendar object.
CharacterArrayType	It is a collection of VARCHAR like: Character[].
CharacterType	This class mapping between a SQL CHAR and a Java Character.
CharArrayType	It is a collection of VARCHAR like: char[].
CharBooleanType	This is a superclass that can be mapping between SQL CHAR and Java boolean.
ClassType	This class mapping between SQL VARCHAR and Java class.
ClobType	This class mapping between SQL CLOB and java.sql.Clob.
CollectionType	It handles the Hibernate PersistentCollections.
ComponentType	This class mapping all components.
CompositeCustomType	It adjusts CompositeUserType to Type interface.;
CurrencyType	It is used to mapping a SQL VARCHAR into a java.util.Currency.
CustomCollectionType	This class is created by users and implement the PersistentCollection.
CustomType	It adjusts the user type to generic type interface and changes the internal type contracts.
DateType	This class mapping between an SQL DATE to Java Date.
DbTimestampType
DoubleType	It can be used to mapping between SQL DOUBLE to Java Double.
EmbeddedComponentType
EntityType	It communicates an entity class.
FloatType	It links SQL FLOAT to Java Float.
ForeignKeyDirection	This class shows directionality of the foreign key constraint.
IdentifierBagType
ImmutableType	This is a superclass of the nullable immutable type.
IntegerType	This class links between the SQL INT to Java Integer.
ListType
LocaleType	It links into an SQL VARCHAR and a Java Locale.
LongType	This class links into an SQL BIGINT and a Java Long.
ManyToOneType	It associates many-to-one entity.
MapType
MetaType
MutableType	This is a superclass of mutable nullable types.
NullableType	This is a supperclass of single-column nullable types.
OneToOneType	It associates one-to-one entity.
OrderedMapType
OrderedSetType
PrimitiveType	This is the superclass of primitive or primitive wrappers types.
SerializableType	This class maps an SQL VARBINARY to a serializable Java object.
SetType
ShortType	It communicates between an SQL SMALLINT and Java Short.
SortedMapType
SortedSetType
SpacialOneToOneType
StringType	It communicates between an SQL VARCHAR and Java String.
TextType	This class links between an SQL CLOB and Java String.
TimestampType	This class mapping between an SQL TIMESTAMP and Java java.util.Date or java.sql.Timestamp.
TimeType	It maps an SQL TIME to Java java.util.Date or java.sql.Time.
TimeZoneType	It communicates an SQL VARCHAR to Java java.util.TimeZone.
TrueFalseType	This class maps an SQL CHAR to a Java Boolean.
TypeFactory	This class used internally and holds an instance of Type.
WrapperBinaryType
YesNoType	It maps between an SQL CHAR to Java Boolean.

Exceptions and Descriptions:
SerializationException	This exception occurs when the property could not be serialized or deserialized.

Can a collection reference be created in hibernate to handle the mappings or do we require to create a specific set/map/list. Can that option be left for runtime?

Hey I am trying to Use the TextType in order to convert Java String to Oracle.sql.blob .....I am getting Oracle type mismatch exp.....I have also upgrade the jdbc drivers from 9i to 10g....I have tried implementing the UserType interface to create a seperate type but with no sucess ....If anybdy is aware of solution to this problem please let me know

Hi Guys, i am facing this net.sf.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or Unsaved-value mapping was incorrect) for sg.gov.moe.rm.edusave.persistence.WDByActBatch instance with identifier 7118-200704-W000003.

WDByActBatch extends persistent object class.

Could anyone highlight, what could be the actual reason of exception and under what circumstances this exception is thrown? what is the best way to solve this?

I am using the following hibernate mapping

<class name="sg.gov.moe.rm.edusave.persistence.EduBatch"
table="RM_EDU_BATCH">
<id name="batchID" column="BATCH_ID" type="java.lang.String">
<generator class="assigned" />
</id>

<version name="version" column="VERSION_NO"
type="java.lang.Short" />

<property name="batchTypeCode" column="BATCH_TYPE"
type="java.lang.Integer" />
<property name="batchStatusCode" column="STATUS_CODE"
type="java.lang.Integer" />
<property name="manual" column="MANUAL_FLAG" type="yes_no" />
<property name="deleteFlag" column="DELETE_IND" type="yes_no" />
<property name="createdBy" column="CREATED_BY" length="20"
type="java.lang.String" not-null="false" />
<property name="createdDate" column="CREATION_DATE"
type="java.util.Date" not-null="false" />
<property name="lastUpdatedBy" column="LAST_UPDATED_BY"
length="20" type="java.lang.String" not-null="false" />
<property name="lastUpdatedDate" column="LAST_UPDATED_DATE"
type="java.util.Date" not-null="false" />
<property name="schoolCPCode" column="SCHOOL_CODE" length="10"
type="java.lang.String" not-null="false" />
<joined-subclass
name="sg.gov.moe.rm.edusave.persistence.WDByActBatch"
table="RM_EDU_WD_BY_ACT_BATCH_HDR">
<key column="BATCH_ID" />

<component name="program"
class="sg.gov.moe.rm.edusave.persistence.Program">
<property name="enrichProgCat"
column="ENRICHMENT_PROG_CAT" />
<property name="progTitle" column="PROGRAMME_TITLE" />
<component name="act"
class="sg.gov.moe.rm.edusave.persistence.Activity">
<property name="actCode" column="activity_code" />
<property name="catCode" column="category_code" />

</component>
</component>
<set name="wdByActBatchDtls" cascade="delete">
<key column="BATCH_ID" />
<one-to-many
class="sg.gov.moe.rm.edusave.persistence.WDByActBatchDtl" />
</set>
<property name="createdBy" column="CREATED_BY" length="20"
type="java.lang.String" not-null="false" />
<property name="createdDate" column="CREATION_DATE"
type="java.util.Date" not-null="false" />
<property name="lastUpdatedBy" column="LAST_UPDATED_BY"
length="20" type="java.lang.String" not-null="false" />
<property name="lastUpdatedDate" column="LAST_UPDATED_DATE"
type="java.util.Date" not-null="false" />
<property name="versionN" column="VERSION_NO"
type="java.lang.Short" />
</joined-subclass>
</class>

Thank you,
Srinivas.
