      Data corruption

      Description

      The constraint can be subverted using e.g. call SYSCS_UTIL.SYSCS_IMPORT_TABLE, cf. the below script:

      test.sql:
      connect 'jdbc:derby:memory:wombat;create=true';
      create table t_unique_nullable(i int, j int, constraint c_unique_n unique);
      call SYSCS_UTIL.SYSCS_IMPORT_TABLE ('APP', 'T_UNIQUE_NULLABLE', 'test.data', '|', '`', null, 1);
      select * from t_unique_nullable;
      create table t_unique(i int not null, j int, constraint c_unique unique);
      call SYSCS_UTIL.SYSCS_IMPORT_TABLE ('APP', 'T_UNIQUE', 'test.data', '|', '`', null, 1);

      which fails in the second import, but not the first one, given this data file:

      test.data
      1 | 1
      1 | 1
      2 | 2

      run:
      ij version 10.11
      ij> connect 'jdbc:derby:memory:wombat;create=true';
      ij> autocommit off;
      ij> create table t_unique_nullable(i int, j int, constraint c_unique_n unique);
      0 rows inserted/updated/deleted
      ij> call SYSCS_UTIL.SYSCS_IMPORT_TABLE ('APP', 'T_UNIQUE_NULLABLE', 'test.data',
      '|', '`', null, 1);
      0 rows inserted/updated/deleted
      ij> select * from t_unique_nullable;
      I |J
      -----------------------
      1 |1
      1 |1
      2 |2

      3 rows selected
      ij> create table t_unique(i int not null, j int, constraint c_unique unique);
      0 rows inserted/updated/deleted
      ij> call SYSCS_UTIL.SYSCS_IMPORT_TABLE ('APP', 'T_UNIQUE', 'test.data',
      '|', '`', null, 1);
