Hi everybody,
i save eMails into a table. Easy.
A BLOB Field saves the whole mail including attachments into MIME Format.
Now the problem ... a 5MB JPG-File 
So i have a 5MB INSERT Query 
I changed already the max_allowed_packet=10M but the connection breaks down each times.
Some programmers sayed me that's possible to add a such query...
Such a huge mail is an exception, normally all mails which should be added
have a size of some KB...
Is it possible to add a 5MB single INSERT query? If yes, how?
Big thanks

max_allowed_packet was not saved 
I changed his value in MySQL Administrator, then via set max_allowed_packet = 10000000; in a SQL-Query
and in the .ini File.
After re-changing these values, it worked
Now i can add those huge inserts easily

Will you recommend the usage of temporary tables in a SQL server database ? AFAIK, it boosts the performance. But recently I read one article in SQL Server performance.com[^] which confused me. Any insights on this would be helpful ?

I have also read that temporary tables can slow performance.
In my experience however - if you do not go overboard in terms of how many rows you load into a temporary table you should not notice any performance issues.
IMHO from a programming side it is always more beautiful to use joins than lots of temporary tables - if you can manage without temporary tables.
You always pass failure on the way to success.

Thanks, But I heard if we have several joins, it can be splitted into temporary table which can boost the performance. And I think performance depends on the situation where we use temporary tables. I guess performance would be costly when it is used for indexing. Because it needs more effort for recompilation.

The key sentance from the article that you reference is:
While temporary table may sometimes be unavoidable, they can often be sidestepped by using derived tables instead.
The article doesn't mean that temporary tables should never be used - only that the author has noticed that some programmers over-use temporary tables when other methods would be more efficient.

Is there any way you can take your input as XML and use OpenXML instead of this nasty string mashing ?

Can u try the following:
-- Code
declare @ExpList varchar (1000)
, @Delimiter char (1)
, @INTValue varchar (20)
, @Position int
begin
create table #Result
(
IntValue int
)
set @ExpList = '10, 11, 12, 13, 14'
set @Delimiter = ','
set @ExpList = ltrim (rtrim (@ExpList)) + @Delimiter
set @Position = charindex (@Delimiter, @ExpList, 1)
if replace (@ExpList, @Delimiter, '') <> ''
begin
while @Position > 0
begin
set @INTValue = ltrim (rtrim (left (@ExpList, @Position -1)))
if @INTValue <> ''
begin
insert into #Result (IntValue)
values (cast (@INTValue as int))
end
set @ExpList = right (@ExpList, len (@ExpList) - @Position)
set @Position = charindex (@Delimiter, @ExpList, 1)
end
end
select * from #Result
truncate table #Result
drop table #Result
end
go
Sample OUTPUT:
--------------
IntValue
--------
10
11
12
13
14
-- End of Code

set @pos = 1
set @start = 1

Modified your code, see the below code:
declare @exp varchar(100)
, @start int
, @pos int
, @substring varchar(20)
set @exp = '12,13,14'
--set @pos = 1
set @start = 1
set @pos = charindex(',' , @exp , @start) -- Added here
while(@pos <> 0)
begin
--set @pos = charindex(',' , @exp , @start)
if(@pos = 0)
begin
print substring(@exp , @start , len(@exp))
return
end
print substring(@exp , @start , @pos -1)
set @pos = charindex(',' , @exp , @start) -- Added here
set @start = @pos + 1
end
go

Sonia Gupta wrote: print substring(@exp , @start , @pos -1)
while executing this statement
1st time, @start is 1 and @pos is 3. so 12 is printed
2nd time, @start is 4 and @pos is 6. so 13,14 is printed i.e. from 4th position 6 characters are printed

No, it isn't stored like that. You are confusing storage formats with presentation formats. It is stored as a 32 or 64 bit number in a way that is efficient for querying. The presentation format should normally be done by the application using the database rather than the database itself.

G'day folks,
I have been experiencing an extremely strange problem in my code, this has to be marked as a X-File episode.
I have a method in my class which executes two other methods. One method(Method A) inserts a row in table A and the other (Method B) inserts a row in table B. This is part of an asp.net application.
When I run the the asp.net application without debugging both methods (A and B) execute fine, however method B doesnt seem to be updating table B whereas Method A updates Table A just fine.
I ran my query through MS Access with test data and the table got updated. Then I decided to step through the code and again method B seems to be updating table B.
I run the application again without debugging and samething happens Table B doesnt get updated and Table A is getting updated.
For the life of me I cant seem to point my finger where the problem is residing. Can this be a connectivity issue with MS Access and my asp.net application ? Both the asp.net and access database are residing in my development environment.
Any pointers will be appreciated.
thanks

Seriously, you might want to also put in some tracing code so that you can see exactly what is being sent to the database (or if the method is being called)
Or perhaps there is something obvious in the method itself that is different from the other method.

LOL Colin that's one funny pointer.
I managed to work out my problem, it was do with timing issue. By the time MethodA finishes executing, I believe access has not had time to update Table A, then MethodB starts executing and Table A is missing the relavant data and MethodB fails to insert a row in Table B.
Why does it work in debug mode well when debugging there is ample time for Access to actually commit the data into the table.
Solution was to a a Thread.Sleep() to cause pause and it all works.
Yes you are right about placing tracing code.
<br />
public void AddStuffToDB()<br />
{<br />
MethodA(string x,string y);<br />
<br />
MethodB(string x);<br />
}<br />

Hello,
i have a ms access database, there is information written in cyrillic encoding. When i read the text from c++ using Ado, it cannt read proper text, it reads only "???????????????", what should i do to read correct text in c++?
here is the code
<br />
CString strItem;<br />
strItem = (char *) (_bstr_t) pRecordPtr->Fields->GetItem("name")->Value;<br />
strItem is "?????" if when encoding is cyrillic.
OR
Is there sql command like "SET CHARACTER SET utf8" in Jet Sql, Mysql has the command, but wondering that Microsoft Jet sql has it?
if Microsoft Jet Sql has it, it would be better to change encoding
thanks

Hello everyone.
I h've been trying for the last week to access a variable in my SSIS package and foward it down to a Data Conversion Item. I've read that I could use a Derived Column or a Script Component Item but I have not had any luck. When I use the Script Componet I am able to test the variable value by adding the code Msgbox(Me.Variables.WMWeekNbr) in the method CreateNewOutputRows in the ScriptMain class. I see the message box with value but it doesn't foward to the data conversion item. I did add the variable to ReadOnlyVariables property. I also created a output columns on the script object.
Im basically trying to create a C# application that will take a value and pass it to the SQL SSIS package which will delete values from the database.
Thanks

I am using SSRS 2005 for the remote access of the reports. I will put url on browser, this will show the result. I am using ListChildren method.
catalogItems = rService.ListChildren(Global.ReportPath,true);
But the code is not working. This will make the tree. This should retrieve no. of reports from report server remotely and put in array, catalogItems. Based on the number of reports the another loop will retrieve names of the reports and will populate the tree vi ew.
Help me please.
