hi, i've tried to update cust_survey_answer table... this table links to customer table on cust_survey_answer.memberno = cust_survey_answer.memberno cust_survey_answer primary key was memberno & question_no this table basically have unique combination of both memberno & question_no ( answer sheet for customers ) right now, there are confirmed no duplicate of memberno & question_no combination. even in customer table, all memberno are uniques... no duplicate memberno inside customer table. what i did was, i combined the 2 table, and take the value customer.dealercode to combine as 1 and store into cust_survey_answer.memberno... but when i run the query, the result shows me violation of primary key of cust_survey_answer... my temporary solution was, i remove the primary key of the cust_survey_answer, and ran the script below: ================ update cust_survey_answer set memberno='0'+cast(customer.dealercode as varchar (5)) +'-'+ cust_survey_answer.memberno from customer where cust_survey_answer.memberno=customer.memberno and customer.dealercode is not null and length( trim( customer.dealercode ) ) > 0 and cust_survey_answer.memberno not like '%-%' and cust_survey_answer.memberno is not null and cust_survey_answer.memberno <> '' ============= after i've runs it, i try set back the primary key for table cust_survey_answer ( combination of memberno & question_no ) , and IT WORKS! i was surprised.. i think it's a bug in postgresql ... please help... thank you. best regards, James ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
