Subject [jira] [Created] (DERBY-6374) Bulk insert of data with nullable UNIQUE constraint fails to detect duplicates
Date Mon, 07 Oct 2013 15:24:42 GMT
Dag H. Wanvik created DERBY-6374:
------------------------------------

             Summary: Bulk insert of data with nullable UNIQUE constraint fails to detect
duplicates
                 Key: DERBY-6374
                 URL: https://issues.apache.org/jira/browse/DERBY-6374
             Project: Derby
          Issue Type: Bug
          Components: SQL
            Reporter: Dag H. Wanvik


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(i));
   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(i));
   call SYSCS_UTIL.SYSCS_IMPORT_TABLE ('APP', 'T_UNIQUE', 'test.data', '|', '`', null, 1);

which fails in the second import, but not the first one:

   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(i));
   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(i));
   0 rows inserted/updated/deleted
   ij> call SYSCS_UTIL.SYSCS_IMPORT_TABLE ('APP', 'T_UNIQUE', 'test.data',
        				    '|', '`', null, 1);
