Provide a more helpful message when the incorrect column name is given in a
SELECT statement for a VTI
------------------------------------------------------------------------------------------------------
Key: DERBY-364
URL: http://issues.apache.org/jira/browse/DERBY-364
Project: Derby
Type: Improvement
Components: SQL
Versions: 10.0.2.1, 10.0.2.0, 10.1.0.0
Reporter: David Van Couvering
Priority: Trivial
If you specify a column name incorrectly in a SELECT statement from a VTI, you
get a fairly unhelpful error message
ij> SELECT SQLSTATE FROM new org.apache.derby.diag.ErrorMessages() vti;
ERROR 42X01: Syntax error: Encountered "SQLSTATE" at line 1, column 8.
ij> SELECT SQL_STATE FROM new org.apache.derby.diag.ErrorMessages() vti;
-- list of SQL States returned --
If you do the same thing from a regular table, the error message is much more
clear:
ij> create table foo(id integer);
0 rows inserted/updated/deleted
ij> select ixd from foo;
ERROR 42X04: Column 'IXD' is either not in any table in the FROM list or appears
within a join specification and is outside the scope of the join specification
or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREA
TE or ALTER TABLE statement then 'IXD' is not a column in the target table.
