java.sql.SQLException: [BEA][Oracle JDBCDriver]Unhandled sql type at

...
I have configured weblogic datatsource and using the same
Oracle version : 10g
weblogic version: 9.2
query : SELECT tbl_a.* FROM tbl_a WHERE ID1='' AND Id2=''
Are you using a PreparedStatement? Try specifying null values for each column instead of the empty string, e.g.:
Connection conn = null;
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
conn = getConnection();
pstmt = conn.prepareStatement("SELECT tbl_a.* FROM tbl_a WHERE ID1=? AND Id2=?");
pstmt.setNull(1, java.sql.Types.INTEGER);
pstmt.setNull(2, java.sql.Types.INTEGER);
rs = pstmt.executeQuery();
while (rs.next()) {
//capture data from the returned rows
}
} catch(Exception e) {
e.printStackTrace();
} finally {
pstmt.close();
rs.close();
conn.close();
}
