One failed to enable constraints exchange 2010 or more rows contain values violating non-null, unique, or foreign-key constraints up vote 100 down vote favorite 55 I make an outer join and executed successfully in the informix database but I get the following exception in my code: DataTable dt = TeachingLoadDAL.GetCoursesWithEvalState(i, bat); Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. I know the problem, but I failed to enable constraints tableadapter don't know how to fix it. The second table I make the outer join on contains a composite primary key which are null in the previous outer join query. EDIT: SELECT UNIQUE a.crs_e, a.crs_e || '/ ' || a.crst crs_name, b.period, b.crscls, c.crsday, c.from_lect, c.to_lect, c.to_lect - c.from_lect + 1 Subtraction, c.lect_kind, e.eval, e.batch_no, e.crsnum, e.lect_code, e.prof_course FROM rlm1course a, rfc14crsgrp b, ckj1table c, mnltablelectev d, OUTER(cc1assiscrseval e) WHERE a.crsnum = b.crsnum AND b.crsnum = c.crsnum AND b.crscls = c.crscls AND b.batch_no = c.batch_no AND c.serial_key = d.serial_key AND c.crsnum = e.crsnum AND c.batch_no = e.batch_no AND d.lect_code= e.lect_code AND d.lect_code = .... AND b.batch_no = .... The problem happens with the table cc1assiscrseval. The primary key is (batch_no, crsnum, lect_code). How to fix this problem? EDIT: According to @PaulStock advice: I do what he said, and i get: ? dt.GetErrors()[0] {System.Data.DataRow} HasErrors: true ItemArray: {object[10]} RowError: "Column 'eval' does not allow DBNull.Value." So I solve my problem by replacing e.eval to ,NVL (e.eval,'') eval.and this solves my problem. Thanks a lot. c# asp.net sql database informix share|improve this question edited Jul 3 '14 at 12:27 asked Aug 11 '11 at 13:18 Anyname Donotcare 1,17128
