i have one table programs with primary key on program_code and another table programsdetails with program_code field with check constraint n also with records. now my query is to declare foreign key on program_code of programsdetails.for that i give the command "alter table programsdetails add constraint s1 foreign key(program_code) references programs;" but, i got error message like parent key not found. but i had already given that. so, plz help me out to define a foreign key on a table who has already existing records .

hi,
The problem might be with the records you have. Please check whether Program_code records in Programdetails table are available in program_code in Program table. You might miss a record or more. This could be a probability for your error.
best of luck..
balaji.
