FrontBaseDialect (Hibernate API Documentation) - Hibernate 3.2.3 正式版 API 英文文档
org.hibernate.dialect
Class FrontBaseDialect
java.lang.Object
org.hibernate.dialect.Dialect
org.hibernate.dialect.FrontBaseDialect
- public class FrontBaseDialect
- extends Dialect
An SQL Dialect for Frontbase. Assumes you're using the latest version
of the FrontBase JDBC driver, available from http://frontbase.com/
NOTE: The latest JDBC driver is not always included with the
latest release of FrontBase. Download the driver separately, and enjoy
the informative release notes.
This dialect was tested with JDBC driver version 2.3.1. This driver
contains a bug that causes batches of updates to fail. (The bug should be
fixed in the next release of the JDBC driver.) If you are using JDBC driver
2.3.1, you can work-around this problem by setting the following in your
hibernate.properties file: hibernate.jdbc.batch_size=15

FrontBaseDialect
public FrontBaseDialect()
getAddColumnString
public String getAddColumnString()
- Description copied from class:
Dialect
- The syntax used to add a column to a table (optional).
- Overrides:
getAddColumnString in class Dialect
- Returns:
- The "add column" fragment.
getCascadeConstraintsString
public String getCascadeConstraintsString()
- Description copied from class:
Dialect
- Completely optional cascading drop clause
- Overrides:
getCascadeConstraintsString in class Dialect
- Returns:
- String
dropConstraints
public boolean dropConstraints()
- Description copied from class:
Dialect
- Do we need to drop constraints before dropping tables in this dialect?
- Overrides:
dropConstraints in class Dialect
- Returns:
- True if constraints must be dropped prior to dropping
the table; false otherwise.
getForUpdateString
public String getForUpdateString()
- Does this dialect support the FOR UPDATE syntax. No!
- Overrides:
getForUpdateString in class Dialect
- Returns:
- false always. FrontBase doesn't support this syntax,
which was dropped with SQL92
getCurrentTimestampCallString
public String getCurrentTimestampCallString()
isCurrentTimestampSelectStringCallable
public boolean isCurrentTimestampSelectStringCallable()
- Description copied from class:
Dialect
- Should the value returned by
Dialect.getCurrentTimestampSelectString()
be treated as callable. Typically this indicates that JDBC escape
sytnax is being used...
- Overrides:
isCurrentTimestampSelectStringCallable in class Dialect
- Returns:
- True if the
Dialect.getCurrentTimestampSelectString() return
is callable; false otherwise.
getLockingStrategy
public LockingStrategy getLockingStrategy(Lockable lockable,
LockMode lockMode)
- Description copied from class:
Dialect
- Get a strategy instance which knows how to acquire a database-level lock
of the specified mode for this dialect.
- Overrides:
getLockingStrategy in class Dialect
- Parameters:
lockable - The persister for the entity to be locked.lockMode - The type of lock to be acquired.
- Returns:
- The appropriate locking strategy.
