                                   throws SearchException

Get the name of all tables that depend on the root tables (i.e, all tables that have FKs pointing to the PK of the root table).

Parameters:

connection - database connection

rootTable - root table described above

Returns:

name of all tables that depend on the root table (including the root table), in the right order for insertions

Throws:

SearchException - if an exception occurred while calculating the order

 String[] rootTables)
                                   throws SearchException

Get the name of all tables that depend on the root tables (i.e, all tables that have FKs pointing to the PK of one of the root tables).

Parameters:

connection - database connection

rootTables - array of root tables described above

Returns:

name of all tables that depend on the root tables (including the root tables), in the right order for insertions

Throws:

SearchException - if an exception occurred while calculating the order

public static String[] getDependsOnTables(IDatabaseConnection connection,
 String rootTable)
                                   throws SearchException

Get the name of all tables that the given rootTable depends on (i.e, all tables whose PK is a FK for the root table).

Parameters:

connection - database connection
