Finding all tables and fields on "many" side of relations with a certain table


in Sql Server 2005, I have a master table, and several other tables which are related to this master through several one to many relations. How can I find all tables and fields which are in relation with the primary key in the master table, on "many" side?

I know I can extract this by querying views from INFORMATION_SCHEMA, but I don't know where exactly I can find this info.

Thank you


Solution

  • I found the answer with some help on sql server groups I use the following query, which returns me schema name, table and field name on one and many side of the relations:

    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
