Re: Strange behavoir of batches

Yes, I know, I found the problem for me already.
If one does call addBatch() every time it works fine.
But thats not the point.
If I don't do it (there should be 1 line missing each block) but fiddle
around with the second block
{ // original
insert 82 rows (in table B)
2 (in table C)
9 (in table D)
{
{ // changed
2 (in table C)
9 (in table D)
82 (in table B)
{

it works well...

Also It should not matter at all what is in tables B,C and D if I enter
a reference from A to E... but it seems that it does.
If got some minutes free I'll go and get the old code again to reproduce
some things and write a report.
