I agree here... I prefer #1 in just about every case. I just never makes sense to me to store the actual images or documents in the DB itself since it really provides you nothing in the way of performance or search capabilities and I think really adds more weight to your DB than is needed.
Sure, I would guess that you can gain some backup and restore simplicity but I just don't see that as being a real benefit.
Now, it would be cool if you could use a type of image bassed query engine on a DB full of pictures... that would be really neat.. IE: fed in a picture of a particular bird and get back a record set of pictures containing that type of bird, or similar birds with that colorization or marking pattern... but I suspect that would be VERY difficult and not very efficient really. Would still be neat though.
I always wanted to try to write a function that you could feed in an image and a folder and have it search through all the images and see if your input image was a subset (IE: copied section) of one of the images in the source folders...

The link I posted does show a performance difference.
Additionally a factor could be access control, especially when users are managed as data versus actual db users or system users.

If there is any chance that this could move to SqlServer 2008, you might consider FileStream Storage[^].

Hi,
I am having an issue executing a create procedure query to Oracle 10g. I am building the query in C++ (Exhibit A) and executing it using ADO (Exhibit B). In most systems, which I do not manage, the query is build and executed on oracle correctly (see Exhibit D). However, I have this one Oracle server that is, for some odd reason, ignoring the new line feeds (\r\n) (see Exhibit C).
Is there a setting in Oracle that I am over looking?
Your help is appreciated. Thanks in advance. Let me know if you need any more info.
EXHIBIT A - Code in C++ to build query:
CString cstrTmp;cstrTmp =
"CREATE OR REPLACE PROCEDURE \"DoSomething\" \r\n"
"(\r\n" " pTxt nvarchar2\r\n" ")\r\n"
"as\r\n"
"\r\n"
"vXml XmlType;\r\n"
"vTempCounter int;\r\n"
"\r\n" "begin\r\n"
" --my comment\r\n"
" dbms_output.put_line('test');
"end;\r\n"
EXHIBIT B - This is the code that executes the query above to the database (in c++):
if(pCommand == NULL)
{
pCommand.CreateInstance(__uuidof(Command));
pCommand->CommandType = adCmdText;
}
pCommand->CommandText= _bstr_t(*cBuffer);
pCommand->CommandTimeout = m_pConn->CommandTimeout;
pCommand->ActiveConnection = m_pConn;
pCommand->Execute(NULL, NULL, adExecuteNoRecords);
pCommand = NULL;
EXHIBIT C - This is how the query is seen in the procedure - In one single line. \r\n is ignored:
CREATE OR REPLACE PROCEDURE "DoSomething"(pTxt nvarchar2)asvXml XmlType;vTempCounter int;BEGIN --myComment dbms_utput.put_line('test');END;
EXHIBIT D - It should show up like this after it is created on the database:
CREATE OR REPLACE PROCEDURE "DoSomething"
(pTxt nvarchar2)
asv
Xml XmlType;
vTempCounter int;
BEGIN
-- my comment
dbms_output.put_line('test');
END;

For the one Oracle server that produces your Exhibit C, is that a Windows server or some other flavour OS that is hosting Oracle.

Its a Windows 2008 machine.

Since it is Windows, it's more probable that it is not dropping your escape characters. I was just wanting to see if some flavour of Unix was involved and somehow along with translating the characters, it was also dropping them. Not sure what else you can look at, though. Sorry.

My first thought was unix as well. The user swears that it's a windows. Is there a query I can run to figure out what is the server is running on?

Dear Friends,
I have a query in which there is a sub query that is fetching a no of rows (single column); it may be one,two..upto six (not more than that). It is using for xml path( '' ) feature of SQL server in order to display the values as comma separated values.
The query is as follows:-
select distinct (select top 1 CLAIMMASTERID from ClaimMaster where encounterid='87B6D11C-3680-44A5-B1DB-AB16B3907AA6') ,EVC.EncounterID,EVC.CPT,(select (select ICDCode + ',' as [text()] from VisitTypeICDCPT soi where soi.VisitTypeID = t.VisitTypeID and VisitTypeID=VTI.VisitTypeID and encounterid='87B6D11C-3680-44A5-B1DB-AB16B3907AA6' order by VisitTypeID for xml path( '' )) from (select distinct VisitTypeID from VisitTypeICDCPT where VisitTypeID=VTI.VisitTypeID and encounterid='87B6D11C-3680-44A5-B1DB-AB16B3907AA6') as t )DiagnosisCode,EVC.Fee,convert(varchar(10),'2010-12-14 00:00:00.000',101) from EncounterVisitCode EVC inner join VisitTypeICDCPT VTI on EVC.encounterid=VTI.encounterid where EVC.encounterid='87B6D11C-3680-44A5-B1DB-AB16B3907AA6'
Here the sub query(starting from :-(select (select ICDCode...)) which is fetching the data from the database and the where "Diagnosis Code" is the column name. The data query is fetching is like this:- 004.12,001.20,...upto six values (may be less).
Here i want the values to be replaced by integer values depending upon the no of values being fetched by sub-query i.e., 1,2, if values in no. are two, 1,2,3, if values in no. are three and so on...
I am not able to find any way out to solve this problem. If someone could help me resolve this problem i would be very grateful to him/her.
Thanks

Please wrap your query in <pre lang="sql"><pre> TAG. so that we can see something from that mess.

I copied it out and reformatted, then decided I did not have enough time to decipher all the queries within queries.

Agreed!
But reformatting takes 10 seconds, so if someone else wants to give it a shot:
SELECT DISTINCT (SELECT TOP 1 claimmasterid
FROM claimmaster
WHERE encounterid = '87B6D11C-3680-44A5-B1DB-AB16B3907AA6'),
evc.encounterid,
evc.cpt,
(SELECT (SELECT icdcode + ',' AS [text()]
FROM visittypeicdcpt soi
WHERE soi.visittypeid = t.visittypeid
AND visittypeid = vti.visittypeid
AND encounterid =
'87B6D11C-3680-44A5-B1DB-AB16B3907AA6'
ORDER BY visittypeid
FOR XML PATH( '' ))
FROM (SELECT DISTINCT visittypeid
FROM visittypeicdcpt
WHERE visittypeid = vti.visittypeid
AND encounterid =
'87B6D11C-3680-44A5-B1DB-AB16B3907AA6') AS t
)
diagnosiscode,
evc.fee,
CONVERT(VARCHAR(10), '2010-12-14 00:00:00.000', 101)
FROM encountervisitcode evc
INNER JOIN visittypeicdcpt vti
ON evc.encounterid = vti.encounterid
WHERE evc.encounterid = '87B6D11C-3680-44A5-B1DB-AB16B3907AA6'

Dear djj55,
I have formatted the query. Please go through it and if you have any answer to it then kindly let me know.

I think you haven't applied lang="sql" Yet. It's not indented.

Dear Hiren,
I have made the changes as required.
Kindly provide me with some answer, if you have.

You can use ROW_NUMBER a Inbuilt ranking function in SQL to get only row numbers.
See MSDN[^].

I have the following to read from database:
sql_connection = new MySqlConnection(ConfigurationManager.ConnectionStrings["SQLdb"].ConnectionString);
sql_connection.Open();
sql_command = new MySqlCommand("sp_send_pending_sms", sql_connection);
sql_command.CommandType = CommandType.StoredProcedure;
sql_reader = sql_command.ExecuteReader();
after reading I want to update every record when send to set the field is_sent to True?
how can i do this? do I have to create another reader in the middle? can you please guide..
Thanks

A little bit confusing about your question whatever,
In case of save,update and delete
you need to execute Transact SQL statement against connection.
