Hi All ... in my form app. i have textboxs related databindings yonet_ogrt and I have 2 datagridview yonet_prg
and yonet_nbt.. so I want to all together navigate but textboxs and datagridview related yonet_prg is working but
datagridview related yonet_nbt not working... this is my trouble...
My code like this...
public void vt_iliski()
string sorgu_ogretmen = "select * from ogretmen";
string sorgu_program = "select * from program";
string sorgu_nobet = "select * from nobet";
ds_gnd = new DataSet();
DataTable tablo = new DataTable();
adpt_ogrt = new SqlCeDataAdapter(sorgu_ogretmen, baglan());
adpt_prg = new SqlCeDataAdapter(sorgu_program, baglan());
adpt_nbt = new SqlCeDataAdapter(sorgu_nobet, baglan());
The following subquery returns 1024 records with a single count column. I am trying to return multiple columns with 1024 records. When I make changes to return multiple columns I get 17,000 records instead of 1024 records. I have very litle experience with subqueries. Does anyone have any suggestions?
SELECT IFNULL(COUNT(DISTINCT A.computerid),0) AS 'Machine Count',
A.hotfixID AS 'Last Contact'
FROM (SELECT HF.computerid, HF.hotfixID
FROM hotfixdata HFD
INNER JOIN hotfix HF
ON HF.hotfixid = HFD.hotfixid
AND HFD.ignore <> 1
LEFT OUTER JOIN Computers AS C
AND HF.installed <> 1
AND HF.Approved = 1
GROUP BY HF.hotfixID, HF.ComputerID) A;
I have a class and the data in it has to be stored in the database. I have done this by extracting every single property and sending each of them as input parameters to a stored procedure in the database. But the thing is that the class has too many properties. Is there any way to accomplish this in a single go(lesser amount of code)? OH and I am using C# and Sql Server!
Presumably it throws an exception and posting that exception as part of your post is helpful.
Presuming that the exception is telling you the statement is too big...
If your SQL statement is too long then SQL/C# will have a problem with it. The solution is to reduce the size. (Might note that that could indicate a database design issue as well.)
Using the database import tools (sqlldr?) might help with the problem but might not. If not or you don't want to use it then solutions.
1. Do two calls.
2. Pass in a blob and parse it to create dynamic sql.
If it was me I would presume that there is a design issue.
The thing is I am still new. Is it not good that we do more of the grunt work at the starting stages itself? And DAL coding is quite hectic. Sometimes I really feel why do we need it anyway. Thank you for eye opener atleast.
Search a topic like "Business Intelligence" and you will get an idea of what others are doing.
At a high level, you have a central database which collects data from different systems, then you have reporting tools which either you or your user community can write their own reports. Also, sometimes you can have these reports run on a scheduled basis and have their output delivered to whoever needs it.
The cost of implementing such a system can be quite high.
You might want to implement some pieces of this.
1) Build a tool which will load your data extracts (xml files) into a central database.
2) Create views or stored procedures which "normalize" your data
3) Use a reporting tool to generate the reports you need or show your users how they can connect to the central database via Excel to get their own data. (See topics like Microsoft Query)
Empower the user to access the data and you will spend less time on maintenance.
Best as I can tell from your question you are asking for something that is impossible.
SQL Server normally installs as an application. Thus it is ALWAYS visible on the client machine.
Now you could re-architect your application to use the embedded version of SQL Server (I think.) Then it would appear that only your application existed. I suspect this would require a bit of work. There are limitations to that approach.
Note as well that this has nothing to do with security. Security means something completely different.
If any user want to insert another row in that table then it is not possible message should be display....
Please Just reply the Query & CODE....
A database does not display messages, it holds data. It holds data in bulk, not in "single records". What you want does not make much sense from a data-viewpoint.
Now, this is not the place to "order" code like you do. The questions on the forums are answered by volunteers, in their free time. Put it in a object, serialize it, and stuff it in a single-column blob.
