Hi,

We have a huge table having around 29579242 Rows.The table is huge and there
is no clustered index on the table. There are a couple of non-clustered
indexes.
We have started experiencing these errors. We increased the command timeout
to 120 (2 minutes) but the error isstill occuring on Insert. Data is being
inserted 1 row at a time and is not transactional. Any ideas?

Thanks
Sandhya

If you're using 2.0 or greater, try this:
http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopy(=
vs.80).aspx
I've had very good results with it.

If you're not up to 2.0 yet, another option is to use DTS. You can
create a package and call it in your code. I've Inserted several
million rows in seconds with this.

Sandhya,

Do you use code, most probably is it only updating the first row in an
endless loop.

You will not be the first one doing that.

Hello Sandhya Kumar

According to your description, you received an exception that "Timeout
expired." when inserting a row into a huge table (which includes 29579242
rows). Please correct me if I misunderstood anything.

Have you tried to set the command timeout to "0" (which indications no
limit)? Will you get the timeout expired exception again? Base on my
experience, such timeout issue should be resolved after we increased the
command timeout (SqlCommand.CommandTimeout property).

If the issue still persists, would you please paste the code snippet about
how you execute SQLCommand in newsgroup? We need more detailed information.
I will follow up. We are glad to assist you. Thanks.

Have a great day,
Best regards,

Wen Yuan,

I would not give a reaction earlier however now you sustain, setting a
connection time out to 0 is in the documentation from Microsoft a solution
that should be avoided. Have a look at what I wrote the chance that the
problem is that is in my idea more then 80%.

Hello Cor,
Thanks for your suggestion.

I agree with you, setting time out property to 0 is not the solution for
this issue. I just want to check if Sandhya still receives the same error
message after setting the timeout property to 0. I wonder why the issue
still persists, even though the command timeout has been increased to 2
minutes. This sounds strange. If the issue still persists after we set the
time out to No limit, there must be something we are missing.

Therefore, I replied again, and want to know what happens after Sandhya set
the time out to 0. Thanks.

Have a great day,
Best regards,
