Re: Block Insert fails...

I have never used them before, but does this help at all?

So nobody has any thoughts on this?

Is anybody out there using block inserts?

Thanks!

All,

I've got the following code, in a Java program I'm running from QShell

try {
Statement stmt = sqlConn.createStatement();
ResultSet rs = stmt.executeQuery("select select varchar05,
intfld, varchar02 " +
" from
CINTAS.cadmin.sometable");

PreparedStatement ps = i5Conn.prepareStatement("INSERT INTO
CINTASDTA.INACTCAB VALUES(?,?,?)");

while (rs.next()) {
ps.setString(1,rs.getString(1));
ps.setLong(2,rs.getLong(2));
ps.setString(3,rs.getString(3));
ps.addBatch();
}

ps.executeBatch();

} catch (SQLException e) {
System.out.println(e.getMessage());
}
}

When the "use block insert" property is set to true, it fails with a
message:
"Error occurred in SQL Call Level Interface - HY009 "

There's a job log created which has the following:
SQ99999 Diagnostic 30 12/16/08 08:53:35.935112

valid. 10 -- Function sequence error. 12

If I change "use block insert" to FALSE, it works fine.

Also, I can leave "use block insert" to TRUE and have it work if

instead

of

batching the inserts, I do them one at a time:
try {
Statement stmt = sqlConn.createStatement();
ResultSet rs = stmt.executeQuery("select varchar05, intfld,
varchar02 " +
" from
CINTAS.cadmin.sometable");

PreparedStatement ps = i5Conn.prepareStatement("INSERT INTO
CINTASDTA.INACTCAB VALUES(?,?,?)");

while (rs.next()) {
ps.setString(1,rs.getString(1));
ps.setLong(2,rs.getLong(2));
ps.setString(3,rs.getString(3));
ps.executeUpdate();
}
} catch (SQLException e) {
System.out.println(e.getMessage());
}
}

But I think when the inserts are not batched they are not blocked

either...

Does anybody know what I'm doing wrong?

There's just over 44,000 rows being inserted, perhaps that's to many

for

one batch?

Thanks!
