determines the rules for foreign key constraints.

Variable Documentation

CASCADE

const long CASCADE = 0

a possible value for the column's UPDATE_RULE and DELETE_RULE in the com::sun::star::sdbc::XResultSet objects returned by the methods com::sun::star::sdbc::XDatabaseMetaData::getImportedKeys(), com::sun::star::sdbc::XDatabaseMetaData::getExportedKeys(), and com::sun::star::sdbc::XDatabaseMetaData::getCrossReference().

For the column UPDATE_RULE , it indicates that when the primary key is updated, the foreign key (imported key) is changed to agree with it.

For the column DELETE_RULE , it indicates that when the primary key is deleted, rows that imported that key are deleted.

NO_ACTION

const long NO_ACTION = 3

a possible value for the column's UPDATE_RULE and DELETE_RULE in the com::sun::star::sdbc::XResultSet objects returned by the methods com::sun::star::sdbc::XDatabaseMetaData::getImportedKeys(), com::sun::star::sdbc::XDatabaseMetaData::getExportedKeys(), and com::sun::star::sdbc::XDatabaseMetaData::getCrossReference().

For the columns UPDATE_RULE and DELETE_RULE , it indicates that if the primary key has been imported, it cannot be updated or deleted.

RESTRICT

const long RESTRICT = 1

a possible value for the column's UPDATE_RULE and DELETE_RULE in the com::sun::star::sdbc::XResultSet objects returned by the methods com::sun::star::sdbc::XDatabaseMetaData::getImportedKeys(), com::sun::star::sdbc::XDatabaseMetaData::getExportedKeys(), and com::sun::star::sdbc::XDatabaseMetaData::getCrossReference().

For the column UPDATE_RULE , it indicates that a primary key may not be updated if it has been imported by another table as a foreign key.

For the column DELETE_RULE , it indicates that a primary key may not be deleted if it has been imported by another table as a foreign key.

SET_DEFAULT

const long SET_DEFAULT = 4

a possible value for the column's UPDATE_RULE and DELETE_RULE in the com::sun::star::sdbc::XResultSet objects returned by the methods com::sun::star::sdbc::XDatabaseMetaData::getImportedKeys(), com::sun::star::sdbc::XDatabaseMetaData::getExportedKeys(), and com::sun::star::sdbc::XDatabaseMetaData::getCrossReference().

For the columns UPDATE_RULE and DELETE_RULE , it indicates that if the primary key is updated or deleted, the foreign key (imported key) is set to the default value.

SET_NULL

const long SET_NULL = 2

a possible value for the column's UPDATE_RULE and DELETE_RULE in the com::sun::star::sdbc::XResultSet objects returned by the methods com::sun::star::sdbc::XDatabaseMetaData::getImportedKeys(), com::sun::star::sdbc::XDatabaseMetaData::getExportedKeys(), and com::sun::star::sdbc::XDatabaseMetaData::getCrossReference().

For the columns UPDATE_RULE and DELETE_RULE , it indicates that when the primary key is updated or deleted, the foreign key (imported key) is changed to NULL.
