JDBC Call returns no results, SQL*Plus returns 1 record, Please help!

Question

Any help would be greatly appreciated.
Running 9.2.0.5.0, and using latest 9.2 JDBC 1.4_g drivers in thin mode.
Execute the following query from SQL*Plus and it returns one row, from JDBC using a PreparedStatement, I get no results. Here's the query, table def, record, etc.:
Query:
SELECT
ID_WEB_FRM,ID_WEB_SIT,CDE_LVL_1_FUNC,
CDE_LVL_2_FUNC,NUM_WEB_FUNC_PG,NUM_WEB_PG_ID
FROM
WEB_FRM
WHERE
ID_WEB_FRM = ' '
OR
(ID_WEB_SIT = 'test' AND CDE_LVL_1_FUNC = ' '
AND CDE_LVL_2_FUNC = 'u2T' AND NUM_WEB_FUNC_PG = 1
AND NUM_WEB_PG_ID = 0)
Record returned from SQL*Plus:
ID_WEB_FRM ID_WEB_SIT CDE CDE NUM_WEB_FUNC_PG NUM_WEB_PG_ID
NfRRmc5XZu test u2T 1 0
Both in the data returned and the query, there are no blanks, but they are a single space instead (hard to see in message here).
Java code:
int count = 1;
findDBNameStatement.setString(count++," ");
findDBNameStatement.setString(count++,form.getSiteID());
findDBNameStatement.setString(count++," ");
findDBNameStatement.setString(count++, form.getFunctionID());
findDBNameStatement.setInt(count++,form.getPageNumber());
findDBNameStatement.setInt(count++,form.getSectionNumber());
ResultSet resultSet = findDBNameStatement.executeQuery();
ResultSetMetaData metaData = resultSet.getMetaData();
resultSet.next() returns false
DB table:
CREATE TABLE web_frm (
ID_WEB_FRM varchar2(10) NOT NULL,
ID_WEB_SIT varchar2(20) NOT NULL,
NAM_WEB_FRM varchar2(40),
TXT_EMAIL_SUBJ varchar2(50),
CDE_LVL_1_FUNC char(3),
CDE_LVL_2_FUNC char(3) NOT NULL,

TXT_WEB_HDR varchar2(4000),
TXT_WEB_FTR varchar2(4000),
TXT_WAIT_LIST_MSG varchar2(255),
FORMOBJECTHEIGHT int NOT NULL,
FORMOBJECTWIDTH int NOT NULL
ALTER TABLE web_frm ADD ( CONSTRAINT PK_web_frm PRIMARY KEY (ID_WEB_FRM));
ALTER TABLE web_frm ADD ( CONSTRAINT UK_web_frm UNIQUE (ID_WEB_SIT,CDE_LVL_1_FUNC,CDE_LVL_2_FUNC,NUM_WEB_FUNC_PG,NUM_WEB_PG_ID)) ;
Thanks,

Answer 1

I have verified the parameters and such, and if I run as a Statement instead of a PreparedStatement, the query works fine. After some more troubleshooting, I narrowed the problem down, but not sure of the fix.
If I eliminate teh extra parameters and simplify things to:
SELECT ID_WEB_FRM FROM WEB_FRM WHERE ID_WEB_SIT = 'test' AND CDE_LVL_2_FUNC = 'u2T' AND NUM_WEB_FUNC_PG = 1 AND NUM_WEB_PG_ID = 0
The code works. But if I add the additional WHERE clause of CDE_LVL_1_FUNC = ' ' (has single space), it returns no data (record in the DB has single space in this new column. Query that does not work:
SELECT ID_WEB_FRM FROM WEB_FRM WHERE ID_WEB_SIT = 'test' AND CDE_LVL_1_FUNC = ' ' AND CDE_LVL_2_FUNC = 'u2T' AND NUM_WEB_FUNC_PG = 1 AND NUM_WEB_PG_ID = 0
It appears the JDBC Driver is trimming the parameter when it is a space when set through a PreparedStatement.setString(2," ")
