public static final String VENDOR_ORACLE

Constant Field Values

useTriggersForAutoAssign

public boolean useTriggersForAutoAssign

If true, then simulate auto-assigned values in Oracle by using a trigger that inserts a sequence value into the primary key value when a row is inserted.

autoAssignSequenceName

public String autoAssignSequenceName

The global sequence name to use for autoassign simulation.

nativeJavaTimeSupport

public boolean nativeJavaTimeSupport

Whether this JDBC driver has native java.time support for LocalDate, LocalDateTime, LocalTime, OffsetTime and OffsetDateTime

openjpa3GeneratedKeyNames

public boolean openjpa3GeneratedKeyNames

Flag to use OpenJPA 0.3 style naming for auto assign sequence name and trigger name for backwards compatibility.

useSetFormOfUseForUnicode

public boolean useSetFormOfUseForUnicode

If true, then OpenJPA will attempt to use the special OraclePreparedStatement.setFormOfUse method to configure statements that it detects are operating on unicode fields.

supportsSetClob

@Deprecated
public boolean supportsSetClob

Deprecated.

This variable was used prior to 2.1.x to indicate that OpenJPA should attempt to use a Reader-based JDBC 4.0 method to set Clob or XML data. It allowed XMLType and Clob values larger than 4000 bytes to be used. For 2.1.x+, code was added to allow said functionality by default (see OPENJPA-1691). For forward compatibility, this variable should not be removed.

xmlTypeMarker

public String xmlTypeMarker

Type constructor for XML column, used in INSERT and UPDATE statements.

Method Detail

endConfiguration

public void endConfiguration()

Description copied from interface: Configurable

Invoked upon completion of bean property configuration for this object.

Specified by:

endConfiguration in interface Configurable

Overrides:

endConfiguration in class DBDictionary

connectedConfiguration

public void connectedConfiguration(Connection conn)
                            throws SQLException

Description copied from class: DBDictionary

This method is called when the dictionary first sees any connection. It is used to initialize dictionary metadata if needed. If you override this method, be sure to call super.connectedConfiguration.

Overrides:

connectedConfiguration in class DBDictionary

Throws:

SQLException

ensureDriverVendor

public void ensureDriverVendor()

Ensure that the driver vendor has been set, and if not, set it now.

supportsLocking

public boolean supportsLocking(Select sel)

Description copied from class: DBDictionary

This method is used for each column from within getCreateTableSQL(org.apache.openjpa.jdbc.schema.Table) and DBDictionary.getAddColumnSQL(org.apache.openjpa.jdbc.schema.Column).
