Cannot insert from EXCEPT/INTERSECT when target table has more columns than the
source
--------------------------------------------------------------------------------------
Key: DERBY-4433
URL: https://issues.apache.org/jira/browse/DERBY-4433
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.6.0.0
Reporter: Knut Anders Hatlen
If an INSERT statement takes the rows to insert from an EXCEPT query or an
INTERSECT query, the statement fails with "Column position 'X' out of range" if
the target table contains more columns than the result returned from EXCEPT or
INTERSECT.
Example:
ij> create table t (x int, y int);
0 rows inserted/updated/deleted
ij> insert into t(x) select x from t except select x from t;
ERROR 42X77: Column position '2' is out of range for the query expression.
ij> insert into t(x) select x from t intersect select x from t;
ERROR 42X77: Column position '2' is out of range for the query expression.
The corresponding UNION query works:
ij> insert into t(x) select x from t union select x from t;
0 rows inserted/updated/deleted
