Re: Inserting packed values into a DB2/400 table via JDBC

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Ed,

What Marshall describes will work fine but if you do this in a loop or
more than once you might want to use a PreparedStatement. The steps are
about the same but you would supply question marks (?) for place holders
as "insert into it005p (item_number) values(?)" and set them by their
ordinal position like: myPreparedStatement.setBigDecimal(1, new
BigDecimal("5555.55")); In this case the one is the 1st ?.

You are making things way too difficult.  The SQL processor on the 400

will take care of packing the data for you.  Just create an SQL string

containing:

INSERT INTO IT005P (ITEM_NUMBER) VALUES(47001)

and execute it.

Inserting packed values into a DB2/400 table via JDBC






Hi All

I've got a table that has several packed columns.  How do I insert
packed
values into this table from a Windows PC via JDBC?  I'm using JTOpen
4.5.

Here is a snippet of the code I'm using to try and create the value:

Connection con = null;
com.ibm.as400.access.AS400PackedDecimal a = new 
     com.ibm.as400.access.AS400PackedDecimal( 7, 0 );

::: snipped connection code :::

   // Create and execute SQL Insert 
   Statement stmt = con.createStatement();
   byte[] b = a.toBytes( new BigDecimal( 47001 ) );
   String value = b.toString();

   String SQLStmt =
                 "INSERT INTO IT005P " +
        "(ITEM_NUMBER) " +
        "VALUES(\"" + value + "\")";

   ResultSet rs = con.execute( SQLStmt );

::: remainder of program snipped :::

Of course, what I see if I log the SQL statement is:

SQL Statement = INSERT INTO IT005P (ITEM_NUMBER) VALUES("[B@16672d6")

Error: [SQL0206] Column "[B@16672d6" not in specified tables.

If anyone has any ideas, I'd really appreciate it.

Thanks!
