Method Detail

copyInto

public void copyInto(Platform platform)

INTERNAL: Allow for conversion from the Oralce type to the Java type.

Specified by:

copyInto in interface Platform

Overrides:

copyInto in class DatabasePlatform

getConnection

public Connection getConnection(AbstractSession session,
                                Connection connection)

INTERNAL: This method is used to unwrap the oracle connection wrapped by the application server. TopLink needs this unwrapped connection for certain Oracle Specific support. (ie TIMESTAMPTZ, LOB) This is added as a workaround for bug 4565190

Overrides:

getConnection in class DatabasePlatform

getCustomModifyValueForCall

public Object getCustomModifyValueForCall(Call call,
                                          Object value,
                                          DatabaseField field,
                                          boolean shouldBind)

INTERNAL Used by SQLCall.translate(..) Typically there is no field translation (and this is default implementation). However on different platforms (Oracle) there are cases such that the values for binding and appending may be different (BLOB, CLOB). In these special cases the method returns a wrapper object which knows whether it should be bound or appended and knows how to do that.

Specified by:

getCustomModifyValueForCall in interface Platform

Overrides:

getCustomModifyValueForCall in class DatabasePlatform

shouldUseCustomModifyForCall

public boolean shouldUseCustomModifyForCall(DatabaseField field)

INTERNAL Used by SQLCall.appendModify(..) If the field should be passed to customModifyInDatabaseCall, retun true, otherwise false. Methods shouldCustomModifyInDatabaseCall and customModifyInDatabaseCall should be kept in sync: shouldCustomModifyInDatabaseCall should return true if and only if the field is handled by customModifyInDatabaseCall.

Specified by:

shouldUseCustomModifyForCall in interface Platform

Overrides:

shouldUseCustomModifyForCall in class DatabasePlatform

writeLOB

public void writeLOB(DatabaseField field,
                     Object value,
                     ResultSet resultSet,
                     AbstractSession session)
              throws SQLException

INTERNAL: Write LOB value - only on Oracle8 and up

Overrides:

writeLOB in class DatabasePlatform

Throws:

SQLException

isNativeConnectionRequiredForLobLocator

public boolean isNativeConnectionRequiredForLobLocator()

INTERNAL: Indicates whether app. server should unwrap connection to use lob locator.

Overrides:

isNativeConnectionRequiredForLobLocator in class OraclePlatform

setShouldUseLocatorForLOBWrite

public void setShouldUseLocatorForLOBWrite(boolean usesLocatorForLOBWrite)

PUBLIC: Set if the locator is required for the LOB write. The default is true. For Oracle thin driver, the locator is recommended for large size ( >4k for Oracle8, >5.9K for Oracle9) BLOB/CLOB value write.

shouldUseLocatorForLOBWrite

public boolean shouldUseLocatorForLOBWrite()

PUBLIC: Return if the locator is required for the LOB write. The default is true. For Oracle thin driver, the locator is recommended for large size ( >4k for Oracle8, >5.9K for Oracle9) BLOB/CLOB value write.

getLobValueLimits

public int getLobValueLimits()

PUBLIC: Return the BLOB/CLOB value limits on thin driver. The default value is 0. If usesLocatorForLOBWrite is true, locator will be used in case the lob's size is larger than lobValueLimit.

setLobValueLimits

public void setLobValueLimits(int lobValueLimits)

PUBLIC: Set the BLOB/CLOB value limits on thin driver. The default value is 0. If usesLocatorForLOBWrite is true, locator will be used in case the lob's size is larger than lobValueLimit.

createArray

public Array createArray(String elementDataTypeName,
                         Object[] elements,
                         Connection connection)
                  throws SQLException

INTERNAL: Platforms that support java.sql.Array may override this method.

Overrides:

createArray in class DatabasePlatform

Returns:

Array

Throws:

SQLException

createStruct

public Struct createStruct(String structTypeName,
                           Object[] attributes,
                           Connection connection)
                    throws SQLException

INTERNAL: Platforms that support java.sql.Struct may override this method.

Overrides:

createStruct in class DatabasePlatform

Returns:

Struct

Throws:

SQLException

getRefValue

public Object getRefValue(Ref ref,
                          Connection connection)
                   throws SQLException

INTERNAL: Overrides DatabasePlatform method.

Overrides:

getRefValue in class DatabasePlatform

Returns:

String

Throws:

SQLException

freeTemporaryObject

public void freeTemporaryObject(Object value)
                         throws SQLException

INTERNAL: Used by Oracle platforms during reading of ResultSet to free temporary LOBs.

Overrides:
