-----------------------------------------------

             Summary: UPSERT failure with generator error
                 Key: TRAFODION-1524
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1524
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-cmp
    Affects Versions: 1.2-incubating
         Environment: Workstation development environment
            Reporter: David Wayne Birdsall


The following log shows an UPSERT statement that fails in the generator. The target table has an index on a non-key column, and the UPSERT statement has a BETWEEN predicate on that same column. Take away either of these conditions and the failure goes away.

>>obey TestBadUpsert(setup1);
>>drop table if exists T1;

--- SQL operation complete.
>>drop table if exists T1backup;

--- SQL operation complete.
>>
>>create table T1
+> ( a integer not null,
+>   b integer not null,
+>   c integer not null,
+>   d char(80),
+>   primary key (a) )
+>salt using 4 partitions;

--- SQL operation complete.
>>
>>
>>insert into T1 values (1,1,1,'hi there!'),
+>  (2,1,1,'a somewhat longer string'),
+>  (3,2,2,'Now is the time for all good men to come to the aid of their country
.'),
+>  (4,3,3,' ');

--- 4 row(s) inserted.
>>
>>
>>-- create another table just like T1
>>create table T1backup like T1;

--- SQL operation complete.
>>
>>insert into T1backup select * from T1;

--- 4 row(s) inserted.
>>
>>obey TestBadUpsert(setup2);
>>
>>create index iT1b on T1(b);

--- SQL operation complete.
>>
>>obey TestBadUpsert(badupsert);
>>
>>-- this upsert fails. Taking out the "between" (say, replacing
>>-- it with an equality predicate) eliminates the failure. 
>>-- Taking out the index on b also eliminates the failure.
>>upsert into T1 select * from T1backup where b between 1 and 2;
