Hmmm, so I will try to explain again. As i said before, I got in database a table with structure:
Arch_table
File_ID fild_type_ID value
00001 1 Peter
00001 3 M
00001 5 blue
00002 1 Jane
00002 3 F
00002 5 red

I would like my program to dispaly some informations form Arch_table (for example Name and sex) in reverse way:
Name (fild_type_ID=1) | Sex (fild_type_Id=3)
Peter | M
Jane | F

This error, what I had written before, occured when I had tried to make a dataset from two dataadapters which were connected to the same table in dataset. ( 1st dataadapter colleted information about name and File_ID, 2nd about sex and File_ID). I can't give code, because I was trying to do that Visual programing.

I hope that this time i make my self clearer.

THX very much for help!!
