Answer 2

我在 sql server groups 的一些帮助下找到了答案
我使用以下查询，它返回关系的一侧和多侧的架构名称、表和字段名称：

SELECT
    SchemaParent.name AS ParentSchemaName, 
    TableParent.name AS ParentTableName, 
    ColumnParent.name AS ParentColumnName, 
    SchemaChild.name AS ChildSchemaName, 
    TableChild.name AS ChildTableName, 
    ColumnChild.name AS ChildColumnName
FROM         
    sys.foreign_key_columns AS kc INNER JOIN
        sys.objects AS TableChild ON kc.parent_object_id = TableChild.object_id INNER JOIN
        sys.schemas AS SchemaChild ON TableChild.schema_id = SchemaChild.schema_id INNER JOIN
        sys.objects AS TableParent ON kc.referenced_object_id = TableParent.object_id INNER JOIN
        sys.schemas AS SchemaParent ON TableParent.schema_id = SchemaParent.schema_id INNER JOIN
        sys.columns AS ColumnParent ON kc.referenced_object_id = ColumnParent.object_id AND kc.referenced_column_id = ColumnParent.column_id INNER JOIN
        sys.columns AS ColumnChild ON kc.parent_object_id = ColumnChild.object_id AND kc.parent_column_id = ColumnChild.column_id
ORDER BY ParentTableName, ChildTableName
