Method Detail

createConstraintPredicate

public static Predicate<String> createConstraintPredicate(com.atlassian.config.db.HibernateConfig hibernateConfig,
                                                          org.hibernate.SessionFactory sessionFactory)

getConstraintsForTable

public static Map<String,List<String>> getConstraintsForTable(com.atlassian.config.db.HibernateConfig hibernateConfig,
                                                              org.hibernate.SessionFactory sessionFactory,
                                                              @Nonnull
                                                              String tableName)

Return a map of unique contraints and it's columns for the given table.

Parameters:

tableName - a table name.

Returns:

map of (constraint_name -> list(columns_name)). Empty if table doesn't exist, or no unique constraints.

constraintsExists

public static boolean constraintsExists(com.atlassian.config.db.HibernateConfig hibernateConfig,
                                        org.hibernate.SessionFactory sessionFactory,
                                        Map<String,com.atlassian.fugue.Pair<String,List<String>>> expectedConstraints)

Take an expected map of [tablename, pair[constraint name, list[column name for constraint]]], and work out if the given constraints for the given table exists in the database.

Parameters:

hibernateConfig - hibernate config

sessionFactory - sessionFactory

expectedConstraints - a map of tablename -> pair[constraint name, list[column name for constraint]], of the expected constraints.

Returns:

true if all of the constraints exist, false otherwise. If any of the table doesn't exist, return false.
