"When considering portability between databases, another important decision "

"emphasis>, <emphasis>identity</emphasis>, or <emphasis>table</emphasis> "

"insidious implication of this approach comes about when targtetting some "

"identifier value; it is what is known as a post-insert generation strategy "

"value. Because Hibernate relies on this identifier value to uniquely "

"When considering portability between databases, another important decision "
|
||||
"is selecting the identifier generation stratagy you want to use. Originally "
|
||||
"Hibernate provided the <emphasis>native</emphasis> generator for this "
|
||||
"purpose, which was intended to select between a <emphasis>sequence</"
|
||||
"emphasis>, <emphasis>identity</emphasis>, or <emphasis>table</emphasis> "
|
||||
"strategy depending on the capability of the underlying database. However, an "
|
||||
"insidious implication of this approach comes about when targtetting some "
|
||||
"databases which support <emphasis>identity</emphasis> generation and some "
|
||||
"which do not. <emphasis>identity</emphasis> generation relies on the SQL "
|
||||
"definition of an IDENTITY (or auto-increment) column to manage the "
|
||||
"identifier value; it is what is known as a post-insert generation strategy "
|
||||
"becauase the insert must actually happen before we can know the identifier "
|
||||
"value. Because Hibernate relies on this identifier value to uniquely "
|
||||
"reference entities within a persistence context it must then issue the "
|
||||
"insert immediately when the users requests the entitiy be associated with "
|
||||
"the session (like via save() e.g.) regardless of current transactional "
|
||||
"semantics. <note> <para> Hibernate was changed slightly once the implication "
|
||||
"of this was better understood so that the insert is delayed in cases where "
|
||||
"that is feasible. </para> </note> The underlying issue is that the actual "
|
||||
"semanctics of the application itself changes in these cases."

"When considering portability between databases, another important decision "

"emphasis>, <emphasis>identity</emphasis>, or <emphasis>table</emphasis> "

"insidious implication of this approach comes about when targtetting some "

"databases which support <emphasis>identity</emphasis> generation and some "

"value. Because Hibernate relies on this identifier value to uniquely "

"reference entities within a persistence context it must then issue the "

"insert immediately when the users requests the entitiy be associated with "

"the session (like via save() e.g.) regardless of current transactional "

"When considering portability between databases, another important decision "

msgid "One of the selling points of Hibernate (and really Object/Relational Mapping as a whole) is the notion of database portability. This could mean an internal IT user migrating from one database vendor to another, or it could mean a framework or deployable application consuming Hibernate to simultaneously target multiple database products by their users. Regardless of the exact scenario, the basic idea is that you want Hibernate to help you run against any number of databases without changes to your code, and ideally without any changes to the mapping metadata."

A dialect encapsulates all the differences in how Hibernate must communicate with a particular database to accomplish some task like getting a sequence value or structuring a SELECT query. Hibernate bundles a wide range of dialects for many of the most popular databases. If you find that your particular database is not among them, it is not terribly difficult to write your own."

The basic contract here is that if the resolver 'understands' the given database metadata then it returns the corresponding Dialect; if not it returns null and the process continues to the next resolver. The signature also identifies <exceptionname>org.hibernate.exception.JDBCConnectionException</exceptionname> as possibly being thrown. A JDBCConnectionException here is interpreted to imply a \"non transient\" (aka non-recoverable) connection problem and is used to indicate an immediate stop to resolution attempts. All other exceptions result in a warning and continuing on to the next resolver."

This might be useful in a number of different situations: it allows easy integration for auto-detection of dialects beyond those shipped with HIbernate itself; it allows you to specify to use a custom dialect when a particular database is recognized; etc. To register one or more resolvers, simply specify them (seperated by commas, tabs or spaces) using the 'hibernate.dialect_resolvers' configuration setting (see the <constant>DIALECT_RESOLVERS</constant> constant on <classname>org.hibernate.cfg.Environment</classname>)."

msgid "When considering portability between databases, another important decision is selecting the identifier generation stratagy you want to use. Originally Hibernate provided the <emphasis>native</emphasis> generator for this purpose, which was intended to select between a <emphasis>sequence</emphasis>, <emphasis>identity</emphasis>, or <emphasis>table</emphasis> strategy depending on the capability of the underlying database. However, an insidious implication of this approach comes about when targtetting some databases which support <emphasis>identity</emphasis> generation and some which do not. <emphasis>identity</emphasis> generation relies on the SQL definition of an IDENTITY (or auto-increment) column to manage the identifier value; it is what is known as a post-insert generation strategy becauase the insert must actually happen before we can know the identifier value. Because Hibernate relies on this identifier value to uniquely reference entities within a persistence context it must then issue the insert immediately when the users requests the entitiy be associated with the session (like via save() e.g.) regardless of current transactional semantics. <note> <para> Hibernate was changed slightly once the implication of this was better understood so that the insert is delayed in cases where that is feasible. </para> </note> The underlying issue is that the actual semanctics of the application itself changes in these cases."

"One of the selling points of Hibernate (and really Object/Relational Mapping "

"mean a framework or deployable application consuming Hibernate to "

"When considering portability between databases, another important decision "

"is selecting the identifier generation stratagy you want to use. Originally "

"Hibernate provided the <emphasis>native</emphasis> generator for this "

"purpose, which was intended to select between a <emphasis>sequence</"
|
||||
"emphasis>, <emphasis>identity</emphasis>, or <emphasis>table</emphasis> "

"insidious implication of this approach comes about when targtetting some "

"databases which support <emphasis>identity</emphasis> generation and some "

"which do not. <emphasis>identity</emphasis> generation relies on the SQL "

"definition of an IDENTITY (or auto-increment) column to manage the "

"identifier value; it is what is known as a post-insert generation strategy "

"becauase the insert must actually happen before we can know the identifier "

"value. Because Hibernate relies on this identifier value to uniquely "

"reference entities within a persistence context it must then issue the "

"insert immediately when the users requests the entitiy be associated with "

"the session (like via save() e.g.) regardless of current transactional "

"When considering portability between databases, another important decision "
