Method Detail

getKeyTable

@Deprecated
TableDefinition getKeyTable()

Deprecated. - [#9672] - jOOQ 3.13 - Use ConstraintDefinition.getTable() instead.

The definition of the referencing table

getKeyColumns

List<ColumnDefinition> getKeyColumns()

The list of columns making up the foreign key.

getReferencedKey

UniqueKeyDefinition getReferencedKey()

The referenced key.

resolveReferencedKey

UniqueKeyDefinition resolveReferencedKey()

Resolve a referenced key.

If getReferencedKey() coincides itself with a foreign key, resolve that foreign key recursively. In case of ambiguity (two foreign keys coinciding with a single unique key), this returns null.

getReferencedTable

TableDefinition getReferencedTable()

The definition of the referenced table.

getReferencedColumns

List<ColumnDefinition> getReferencedColumns()

The list of columns referenced by this foreign key

countSimilarReferences

int countSimilarReferences()

Count the number of references between referencing and referenced tables.
