| Hello,i am trying to to self-reference table (sql server) I am creating it through vusual studio. I get the error'tbl_department' table- Unable to create relationship 'FK_tbl_department_tbl_department'.ALTER TABLE statement conflicted with COLUMN FOREIGN KEY SAME TABLE constraint 'FK_tbl_department_tbl_department'. The conflict occurred in database 'IMS_DB', table 'tbl_department', column 'dpt_id'.any idea ? (this table has other FK but pointing to other tables - they work fine)ThanksChris |

| That's right,dpt_id is the primary key and dpt_parentID is foreign key referencing to dpt_id in the same table.In fact I am following this tutorial [ http://authors.aspalliance.com/joteke/treeviewarticle/article.aspx ] and my table as the same structure as the one in the tutorial ( names are different though! ) |
