Class Dialect
java.lang.Objectorg.hibernate.dialect.Dialect
- Direct Known Subclasses:
- DB2Dialect, FrontBaseDialect, GenericDialect, HSQLDialect, InformixDialect, IngresDialect, InterbaseDialect, JDataStoreDialect, MckoiDialect, MimerSQLDialect, MySQLDialect, Oracle9Dialect, PointbaseDialect, PostgreSQLDialect, ProgressDialect, RDMSOS2200Dialect, SAPDBDialect, SybaseDialect, TimesTenDialect
- public abstract class Dialect
- extends java.lang.Object
Represents a dialect of SQL implemented by a particular RDBMS.
Subclasses implement Hibernate compatibility with different systems.
Subclasses should provide a public default constructor that register()
a set of type mappings and default Hibernate properties.
Subclasses should be immutable.

toString
public java.lang.String toString()
- Description copied from class:
java.lang.Object - Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into System.out.println() 55
and such.
It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.
This method will be called when performing string concatenation with this object. If the result is
null, string concatenation will instead use"null".The default implementation returns
getClass().getName() + "@" + Integer.toHexString(hashCode()).

the ErrorCode rather than the SQLState. Unfortunately, the ErrorCode is a vendor-
specific approach.
