ArrayIndexOutOfBoundsException thrown in PreparedStatement execution
--------------------------------------------------------------------
Key: DERBY-4594
URL: https://issues.apache.org/jira/browse/DERBY-4594
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.5.3.0
Environment: Derby 1.5.3.0_1
Windows XP SP3
Reporter: Arthur Doler
I am encountering the following exception when trying to execute a
PreparedStatement:
{code}
Exception in thread "main" java.sql.SQLException: The exception
'java.lang.ArrayIndexOutOfBoundsException: -1' was thrown while evaluating an
expression.

{/code}
The query I am executing is:
{code}
SELECT R.report_id, ER.entity_id FROM reports AS R
LEFT JOIN entity_reports AS ER ON R.report_id = ER.report_id
WHERE R.details LIKE ?
AND COALESCE(ER.entity_id, 0) != ?
{/code}
The table 'reports' can be prepared with the following SQL:
{code}
ij> CREATE TABLE reports (report_id bigint PRIMARY KEY, document_num
varchar(50), status varchar(100), type varchar(100) NOT NULL, specific
varchar(100), owner varchar(100), summary clob, details clob, closing_remarks
clob, occurred date, opened date, closed date, reference_guid varchar(50) NOT
NULL);
ij> INSERT INTO reports (report_id, type, summary, details, reference_guid)
VALUES (1, 'Type 1', 'Summary 1', 'Details 1', 'guid 1');
{/code}
The table "entity_reports" can be prepared with:
{code}ij> INSERT INTO reports (report_id, type, summary, details,
reference_guid) VALUES (1, 'Type 1', 'Summary 1', 'Details 1', 'guid 1');{/code}
The error happens regardless of whether this table has rows in it or not.
Technically both report_id and entity_id are foreign keys but that doesn't seem
to make a difference.
Executing the above SQL on a new derby database and then running the query,
whether it's via JDBC from Java or directly through ij, causes the problem to
occur.
Here is a copy of the query suitable for execution in ij (i.e., the values are
filled out):
{code}
SELECT R.report_id, ER.entity_id FROM reports AS R
LEFT JOIN entity_reports AS ER ON R.report_id = ER.report_id
WHERE R.details LIKE '%Details%'
AND COALESCE(ER.entity_id, 0) != 1;
{/code}
I'm open to the idea that I'm doing something wrong, but the same code works
against our test MSSQL db.
Thank you for your time.
