所有已实现的接口:

ConversionContext

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

构造器详细资料

FrontBaseDialect

public FrontBaseDialect()

Constructs a FrontBaseDialect

方法详细资料

getAddColumnString

public String getAddColumnString()

从类复制的说明: Dialect

The syntax used to add a column to a table (optional).

覆盖:

getAddColumnString 在类中 Dialect

返回:

The "add column" fragment.

getCascadeConstraintsString

public String getCascadeConstraintsString()

从类复制的说明: Dialect

Completely optional cascading drop clause

覆盖:

getCascadeConstraintsString 在类中 Dialect

返回:

String

dropConstraints

public boolean dropConstraints()

从类复制的说明: Dialect

Do we need to drop constraints before dropping tables in this dialect?

覆盖:

dropConstraints 在类中 Dialect

返回:

True if constraints must be dropped prior to dropping the table; false otherwise.

getForUpdateString

public String getForUpdateString()

FrontBase doesn't support this syntax, which was dropped with SQL92.

Get the string to append to SELECT statements to acquire locks for this dialect.

覆盖:

getForUpdateString 在类中 Dialect

返回:

The appropriate FOR UPDATE clause string.

getCurrentTimestampSelectString

public String getCurrentTimestampSelectString()

从类复制的说明: Dialect

Retrieve the command used to retrieve the current timestamp from the database.

覆盖:

getCurrentTimestampSelectString 在类中 Dialect

返回:

The command.

isCurrentTimestampSelectStringCallable

public boolean isCurrentTimestampSelectStringCallable()

从类复制的说明: Dialect

Should the value returned by Dialect.getCurrentTimestampSelectString() be treated as callable. Typically this indicates that JDBC escape syntax is being used...

覆盖:

isCurrentTimestampSelectStringCallable 在类中 Dialect

返回:

True if the Dialect.getCurrentTimestampSelectString() return is callable; false otherwise.

getLockingStrategy

public LockingStrategy getLockingStrategy(Lockable lockable,
                                          LockMode lockMode)

从类复制的说明: Dialect

Get a strategy instance which knows how to acquire a database-level lock of the specified mode for this dialect.

覆盖:

getLockingStrategy 在类中 Dialect

参数:

lockable - The persister for the entity to be locked.

lockMode - The type of lock to be acquired.

返回:

The appropriate locking strategy.
