Hi,
I want to make a simple document system.
But i don't know what to do store my files in SQL or store a little XML in the table
1. Store the whole file in the DB (like a BLOB or something like this)
including other columns (title, little explanation, author, date,...)
2 Store a little XML file in the DB with a filepath to the file but in XML all the metatags like the
columns in point 1.
I don't know which is the best choise!!!
Ok, i shall restrict the files to a max of 10Mb.
for versioning - The XML solution is maybe better?
Searching goes faster in ...?
performance...? size of DB I think it will grow rapidly?
Security easiest in which solution?
Can anyone put me in the right direction!!!
Please what do you think

You might want to consider using Microsoft SharePoint. It does all of this and is free.

Hi,
Doesn't anyone knows how can I copy a CLR Stored Procedure from one database to another.
|
|
|
|

I haven't done it before but have you tried this:
Source Server:
1) Right-click assembly (under programmability - assemblies - {assembly}) SCRIPT Assembly as.... - CREATE TO - New query window
2) Right-click stored proc (programmability - stored procedures - {stored proc}) SCRIPT stored procedure as... - CREATE To - New query window
Target Server:
Change connection for #1 and execute against target, then change connection for #2 and execute against target

Hi,
We are Beginners in Sql and oracle. We are working with Java as front end and Oracle8i as the back end. We have to retrieve the results of those queries executed with dual table in oracle and display them in our front end.
We have connected Java with oracle using JDBC. Our connection is working properly. So our problem is only regarding retrieving. Pls help us with code.

You have read the bit beside the image of the green alien at the top of this page haven't you? I would take a look at that if I were you, and then ask yourself if this is really the right site to ask this question on.
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

I used to lead an oracle team (I've now seen the light an am back to using SQL-Server ). My developers found Expert Oracle JDBC Performance Applications[^] really useful for JDBC.
However, most of the work was done using Hibernate instead of JDBC. This allowed them to work at a much higher level of abstraction from the database.

I have three tables family,productfamily(cross reference between product table and family),familycontent(cross reference between family and content), productcontent(cross reference between product and content)
Family table itself is the master of its own. Some families may be sub families of other family. For every family we need to go to familycontent table and see if record exists. If it does not, it should check its subfamilies and also productfamily and see whether any of the child family has got contents in familycontent or any of the products under that contains record in productcontent table. Child families can be upto 'n' level. We need to loop through like this until we loop through the entire hierarchy or until we get a record in either of the familycontent or productcontent table. Is there an easy way to get in SQL Query or we need to use Cursor and recursive function/Stored procedure. Please advice

Hi,
I am adding a file to a filegroup on a remote machine, and i don't know the direcotry structure of that machine, how can i provide the path for FILENAME param, since FILENAME params requires complete valid path of a physical file in that system.
ALTER DATABASE TESTDB ADD FILE (NAME = N'TESTFILE', FILENAME = N'physicalfilepath.ndf') TO FILEGROUP TESTFILEGROUP
Warm Regards,

If this is going in the same place as the other files in the group you can find out the existing path with SELECT * FROM sysfiles

Morning guys (GMT guys that is)
I am having issues deciding on exactly how to perform a very large chunk of programming. I need to query the database im working with to build up a table of statistics from the various tables within the database. Each product must be selected and then 10 individual statistics, many involving averaging and percentaging, must be generated per product. Therefore there will be 10 queries x the number of products found run each time.
The thing im not really sure about is quite where to put the programming itself. Should it be in a seperately coded class as part of my ASP.net project or should it be completely coded in sql in a stored procedure.
I need a speed, ease of achievability and also a managability perspective on any proposed technique. Thanks

Hi Sam
I would use a stored procedure based on the following SQL:
SELECT ProductCode,
(SELECT ###Statistics sub-select### FROM MyTable1 A
WHERE A.ProductCode = Product.ProductCode) AS Statistic1,
(SELECT ###Statistics sub-select### FROM MyTable2 A
WHERE A.ProductCode = Product.ProductCode) AS Statistic2,
###etc
FROM Product
ORDER By ProductCode You need to replace the "###" bits with SQL that matches your statistical requirements.
Hope that helps.

Hi everybody,
I wrote a script in Installshield that changes the MaxLocksPerFile value in
Registry for Jet 3.x and Jet 4.0
While installing the application through Installshield, the custom value for
MaxLocksPerFile is being overwritten to 9500 in Registry for Jet
4.0(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Jet 4.0) but not
for Jet 3.x(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Jet 3.x).
The value is being overwritten to 9500 before the control reaches at the
script code.
I am wondering from where this 9500 value is being retrieved and set in
Registry.
Is there some file where these default values are mentioned.
If so then why 9500 value is not being set for Jet 3.x and is being set only
for Jet 4.0.
i am using MS Office 2002. Drivers for ODBC MS Access is above 4.0
and Installshield Version is 5.5.
Please help me to resolve this Issue.
-Regards
Harpreet

Hi,
Actually the what I am trying to implement is the following three requirements:
1) If the registry value Jet MaxLockPerFile is set to 30000 or lower the kit installation should set the value to 30000.
2) If the registry value Jet MaxLockPerFile doesn't exist the kit installation should set the value to 30000.
3) If the registry value Jet MaxLockPerFile is higher than 30000 the kit installation should not change this value in the registry.
To implement the above 3 requirements, I wrote the following script in Installshield:
szRegPath = "SOFTWARE\\Microsoft\\Jet\\4.0\\Engines\\Jet 3.x";
if(RegDBKeyExist(szRegPath) = 1) then
if(RegDBGetKeyValueEx(szRegPath, "MaxLocksPerFile", nzDummy,
szTmp, nzDummy) = 0) then
if (StrToNum (nVar, szTmp) = 0) then
if(nVar < 30000) then
nVar = 30000;
if(NumToStr (szTmp1, nVar) = 0) then
RegDBSetKeyValueEx(szRegPath, "MaxLocksPerFile", REGDB_NUMBER,
szTmp1, -1);
endif;
endif;
endif;
else
RegDBSetKeyValueEx(szRegPath, "MaxLocksPerFile", REGDB_NUMBER,
"30000", -1);
endif;
endif;
szRegPath = "SOFTWARE\\Microsoft\\Jet\\4.0\\Engines\\Jet 4.0";
if(RegDBKeyExist(szRegPath) = 1) then
if(RegDBGetKeyValueEx(szRegPath, "MaxLocksPerFile", nzDummy,
szTmp, nzDummy) = 0) then
if (StrToNum (nVar, szTmp) = 0) then
if(nVar < 30000) then
nVar = 30000;
if(NumToStr (szTmp1, nVar) = 0) then
RegDBSetKeyValueEx(szRegPath, "MaxLocksPerFile", REGDB_NUMBER,
szTmp1, -1);
endif;
endif;
endif;
else
RegDBSetKeyValueEx(szRegPath, "MaxLocksPerFile", REGDB_NUMBER,
"30000", -1);
endif;
endif;
Now for Jet 3.x it is working fine but when i check for fulfilment of the 3rd requirement in Regisrty(for Jet 4.0), the value changes to 30000, if previously it was greater than 30000.
This is because, the RegDBGetKeyValueEx function in script for(above) for Jet 4.0 retrieves the value 9500 instead of the value that we set greater than 30000( say 35000).
This is exactly what is happening. I will be highly obliged if anybody can help me to resolve this issue.

Hi all,
I am developing an employee search appl.I am using a textbox for name where the user can just enter the initials and entire name is searched.I am using stored procedures and passing the entered value as a parameter to stored proc.The problem is i haved framed the query as
select * from employee where fname like '@fname%';
this is not working and returns 0 rows
help!!!
|
|
|
|
|
in your case it is searching for the string starting with "@fname" as no data found starting with this string returns zero rows.
to my understanding @fname, in the query is variable.
if so, the same to be used as ...
select * from employee where fname like '%' + @fname + '%'

Hi,
Is it possible to use the parameter as an alias name for a column or any method I could use?
e.g.
@Conference - accepts either West or East, this is so that I could make use of the SP for Listing teams under East Conference and West Conference.
Create procedure [dbo].[sp_SelectConference]
(
@Conference varchar(20) = null
)
as
begin
select
TeamCity + ' ' + TeamNickName as @Conference + 'Confrence',
NumWins as 'Wins',
NumLoses as 'Loses'
from
teams
where
Conference = @Conference
end
Please advice
Dom;)

To my knowledge it is not possible.
however i'ld like to know the advantage in using alias of this
