RE: Block Insert fails...

I thought the limit for any SQL array operation was 32766.

Hi Kieth,

As mentioned in my other post, I got it working with batches of 5,000
and turning auto-commit off.

I went back and tried to do all 44,000 as a single batch, and the
process fails with the same error I originally received.

So, there does appear to be some limit.

In any event, I'm definitely impressed by the performance. I'm
inserting 44,000 rows in less than 10 seconds.

Hi Charles,

I've used block inserts using PreparedStatement methods addBatch() and
executeBatch() similar to you and it worked ok - although I used
hundreds rather than thousands of inserts. I've never seen a reference

to a batch size limitation.

Does rerun with fewer insert records work?

What driver are you using - does it support batch statements?

Also, try returning the executeBatch to an integer array - to check
the success or failure of each insert:

int[] upCounts = ps.executeBatch();

44,000 elements is a bit much but you could run on a smaller scale.

Keith

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:

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!
