Method Detail

makeRow

public ExecRow makeRow(TupleDescriptor td,
                       TupleDescriptor parent)
                throws StandardException

Make a SYSTRIGGERS row.

Overrides:

makeRow in class CatalogRowFactory

Returns:

Row suitable for inserting into SYSTRIGGERS.

Throws:

StandardException - thrown on failure

makeEmptyRowForCurrentVersion

public ExecRow makeEmptyRowForCurrentVersion()
                                      throws StandardException

Description copied from class: CatalogRowFactory

Create an empty row for this conglomerate, in the format that would be used in a database that was created with, or hard upgraded to, the currently running version. That is, even if the database is only soft-upgraded, this method should return a row in the new format.

This method is for use in code that creates the catalogs, or that upgrades the format of the catalogs to the newest version. Other code should call CatalogRowFactory.makeEmptyRow(), which returns a row in the format used in the old database version if the database is soft-upgraded.

Overrides:

makeEmptyRowForCurrentVersion in class CatalogRowFactory

Returns:

an empty row

Throws:

StandardException - if an error happens when creating the row

buildDescriptor

public TupleDescriptor buildDescriptor(ExecRow row,
                                       TupleDescriptor parentTupleDescriptor,
                                       DataDictionary dd)
                                throws StandardException

Make an Tuple Descriptor out of a SYSTRIGGERS row

Specified by:

buildDescriptor in class CatalogRowFactory

Parameters:

row - a SYSTRIGGERS row

parentTupleDescriptor - unused

dd - dataDictionary

Returns:

a descriptor equivalent to a SYSTRIGGERS row

Throws:

StandardException - thrown on failure

buildColumnList

public SystemColumn[] buildColumnList()
                               throws StandardException

Builds a list of columns suitable for creating this Catalog. The last column, the serialized statement, is not added to the column list. This is done deliberately to make it a 'hidden' column -- one that is not visible to customers, but is visible to the system.

Specified by:

buildColumnList in class CatalogRowFactory

Returns:

array of SystemColumn suitable for making this catalog.

Throws:

StandardException

getHeapColumnCount

public int getHeapColumnCount()
                       throws StandardException

Description copied from class: CatalogRowFactory

Get the number of columns in the heap.

Overrides:

getHeapColumnCount in class CatalogRowFactory

Returns:

The number of columns in the heap.

Throws:

StandardException
