Method Detail

buildSelectQueryForSequenceObject

public ValueReadQuery buildSelectQueryForSequenceObject(String qualifiedSeqName,
                                                        Integer size)

INTERNAL: Produce a DataReadQuery which updates(!) the sequence number in the db and returns it.

Overrides:

buildSelectQueryForSequenceObject in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Parameters:

qualifiedSeqName - known by TimesTen to be a defined sequence

getCreateViewString

public String getCreateViewString()

INTERNAL: Used for view creation.

Overrides:

getCreateViewString in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

getSelectForUpdateString

public String getSelectForUpdateString()

INTERNAL: Used for pessimistic locking.

Overrides:

getSelectForUpdateString in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

getTimestampQuery

public ValueReadQuery getTimestampQuery()

PUBLIC: TimesTen uses the Oracle syntax for getting the current timestamp.

Specified by:

getTimestampQuery in interface org.eclipse.persistence.internal.databaseaccess.Platform

Overrides:

getTimestampQuery in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

isTimesTen

public boolean isTimesTen()

Specified by:

isTimesTen in interface org.eclipse.persistence.internal.databaseaccess.Platform

Overrides:

isTimesTen in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

shouldPrintOuterJoinInWhereClause

public boolean shouldPrintOuterJoinInWhereClause()

Some database require outer joins to be given in the where clause, others require it in the from clause.

Overrides:

shouldPrintOuterJoinInWhereClause in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

supportsSequenceObjects

public boolean supportsSequenceObjects()

INTERNAL: Indicates whether the platform supports sequence objects.

Overrides:

supportsSequenceObjects in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

supportsForeignKeyConstraints

public boolean supportsForeignKeyConstraints()

Overrides:

supportsForeignKeyConstraints in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

setSupportsForeignKeyConstraints

public void setSupportsForeignKeyConstraints(boolean supportsForeignKeyConstraints)

writeParameterMarker

public void writeParameterMarker(Writer writer,
                                 org.eclipse.persistence.internal.expressions.ParameterExpression parameter,
                                 org.eclipse.persistence.internal.sessions.AbstractRecord record,
                                 org.eclipse.persistence.internal.databaseaccess.DatabaseCall call)
                          throws IOException

INTERNAL: TimesTen and requires cast around parameter markers if both operands of certain operators are parameter markers This method generates CAST for parameter markers whose type is correctly identified by the query compiler. This is not used by default, only if isCastRequired is set to true, by default dynamic SQL is used to avoid the issue in only the required cases.

Overrides:

writeParameterMarker in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Throws:

IOException
