sql - I need to create a SQLite table -


i need able enter duplicate entries in table b, different foreign keys (table b references table a's key). this:

table a: record key of 11 record key of 22  table b: record referring table record 11, field marked unique: value 101 record referring table record 22, field marked unique: value 101  <--- violates unique key

this have tried, didn't work:

create table readings (     site_id text references sitedata     , loop_nbr text     , loop_closed binary     , seq integer     , sta text unique     , bs text     , fs text     , hi text     , desc text  )    insert readings (site_id, seq) values (' + databasekey + ', 0)
