Hi there,
I have a problem on Java version 1.1.7, MM JDBC driver 1.2c with mySQL version 3.23.13a-alpha-log. I have a table description, desc log; | Field | Type | Null | Key | Default | Extra | Privileges | +--------------+-------------+------+-----+---------------------+-----------
---- -+---------------------------------+ | logid | bigint(20) | | PRI | NULL | auto_increment | select,insert,update,references | | byteobj | mediumblob | YES | | NULL | | select,insert,update,references |
I can successfully put a file into the database, then retrieve it by using SQL statement --> "select byteobj from log where logid = '1' into dumpfile '/_PATH/try.gif';"
HOWEVER, when I try to retrieve it through MM JDBC 1.2c by using following coding
... try { Statement stmt = con.createStatement(); org.gjt.mm.mysql.ResultSet rs = (org.gjt.mm.mysql.ResultSet) stmt.executeQuery ("SELECT byteobj FROM log WHERE logid = 100"); System.out.println(" Select fileByte finished!");
} catch (Exception e)
{ System.err.println(" select query error."); e.printStackTrace(); } ...
It produces this error. Please NOTE that, the physical size of the file should be equal to 73571. I don't know why the IndexOutOfBoundsException showed the number increased by 4 bytes.
select query error. java.sql.SQLException: Error during query: Unexpected Exception: java.lang.Array IndexOutOfBoundsException message given: 73575 at java.lang.Throwable.<init>(Compiled Code) at java.lang.Exception.<init>(Compiled Code) at java.sql.SQLException.<init>(Compiled Code) at org.gjt.mm.mysql.Connection.execSQL(Compiled Code) at org.gjt.mm.mysql.Connection.execSQL(Compiled Code) at org.gjt.mm.mysql.Statement.executeQuery(Compiled Code) at myDataAccessConfig.<init>(Compiled Code) at myDataAccessConfig.main(Compiled Code)
Any advices?
Thanks in advance.
tony.
