Database

Re: Data Binding, Combo Boxes, and Related tables.

Excellent start, however you need to be aware the datareader lock the connection and should be consumed and disposed of ASAP, passing a datareader is asking for problems. For this reason I use datatable.fill. It uses a datareader under the hood but leaves you with a disconnected datatable as a result.

Also I do not make my DAL class static, I often connect to multiple databases. I do have a static class that hold the main copy of the dal but I often create additional copies for specific connections.

I have a single generic method that moves a datatable into a List<> of the object. I also have a UI helper class that binds a List<> to a form, naming discipline is required.

If you send me an email I will send you a copy of the DAL class.

I tried nHibernate once. It was a bit of a pill to get used to but once I did, I found that it really helped me in the whole binding and persisting work. It doesn't fit with my current work of real time processing ( well it would for system configuration and settings ) but otherwise I would use it all the time.

select gender,amt,age,[address],class ,

Case when gender= '' then 'gender,'when gender is null then 'gender,' Else '' End +
Case when amt = '' then 'amt,'when amt is null then 'amt,' Else '' End +
Case when age = '' then 'age,'when age is null then 'age,' Else '' End +
case when [address] = ''then 'address'when [address] is null then 'address,' else '' End +
Case when class = '' then 'class,'when class is null then 'class,' Else '' End
As [Error Remarks] from mytable

The above query is used to check if any of this row is blank or null display the result in
a column name "error remarks" .
Now the result i m getting is :
gender, amt, age,address,class
all this result is displayed in a single line in a single cell.
now i want the result to be displayed in different line:
like this:
gender,
amt,
age,
[address],
class

all this is single cell with the above query.

i had tried char(13) and 10 . and the value is coming in new line but in sql server textmode and not in grid mode . i want data to be in grid mode.

So do this in the UI where display operations belong! Why are doing such a silly thing as formatting your data for the query results grid, you should be the only person looking at SQL Server results.

How did you use the CHAR(13) and CHAR(10)?

With SQL Enterprise Manager Query Results in grid view you can't display new lines - I came across the same only this week. I think they get converted to spaces deliberately prior to being dumped into the grid so everything stays on the one line. Microsoft made the call - most developers, most of the time, want to see most of their data without stretching the row-height every time they run the query. But trust me, those 13-10s/CR-LFs are working. As someone else said - you are the only person who will see this grid. If you want to whack this query into a .NET winforms grid view, it is possible to get the multi-lines to show there by setting a couple of properties (I could look it up for you, but I won't). And of course, make that query a view, link to the view from Microsoft Access as a linked table and you will see multi-lines. I will now run for cover.

hi all
i have a very important issue,

read this scenario please

i have three Stored Procedures Sp1,Sp2 and Sp3 .

the first one (Sp1) will execute the second one (Sp2) and save returned data into @tempTB1 and the Second one will execute the third one (Sp3) and save data into @tempTB2.

if I execute the Sp2 it will works and it will returned me all my data from the Sp3 ,but the problem is in the Sp1, when i execute it it will display this Error:

INSERT EXEC statement cannot be nested

I tried to change the place of execute Sp2 and it display me another error:

Cannot use the ROLLBACK statement within an INSERT-EXEC statement.

Create database to share folder

Hi all,

Currently, I used SQL Server 2008 to create database on share folder as below query:

DBCC TRACEON (1807,-1)

CREATE DATABASE 20100914 ON (NAME="20100914_dat",FILENAME="\\HOST1\SHARE\20100914_DATA.MDF") LOG ON (NAME="20100914_log",FILENAME="\\HOST1\SHARE\20100914_LOG.LDF")

with \\HOST1\SHARE has full permission for all person.

When I run above query, the error is shown:
System.Data.SqlClient.SqlException: Directory lookup for the file "\\HOST1\SHARE\20100914_DATA.MDF" failed with the operating system error 5(failed to retrieve text for this error. Reason: 15105).

CREATE DATABASE failed. Some file names listed could not be created. Check related errors.

Pls help me to solve it if you know.

Thanks a lot.

Error 5 indicates that the access has been denied; your share probably needs a username/password combination. If you want to share your data, create a TCP/IP connection to the server from a remote machine, putting the database on a unc-path is asking for problems;

MSDN states:[^]
If access to a disk resource requires that a share be mapped, or if the disk resource appears as a remote server through a UNC path, (for example, \\Servername\Sharename), on the network, then by default, the disk storage system is not supported as a location for SQL Server databases.

Do you really expect anyone to read and study all that, while you are not even providing a decent description of what it does, what it is about, why you think it should run faster, and what you tried to get it any faster?

Actually it runs fine.
There was a post in the lounge regarding this particular statement and rather than post it in the lounge I posted it here and linked it.
What is does is get information for a facesheet which is basically all information on a client.
Like I said performance is not a problem there was just a conversation about the code being incorrect if it was so many lines of code.

Create a view so no other poor bugger has to look at this code again.

I would probably break it into a number of different procs servicing different parts of the profile. Supporting this query would be nasty.

What happens when the dietician want the name and diet details, does he get all of the face sheet.

In the case of the dietician needs info we would generally do that on a different report with only the information needed by them.
I do think that breaking the SQL out to bring in only parts of the profile is a good idea then we could more easily reuse them.
However a concern of mine in doing that would be that if we have to tie all of these back together would that not be a pretty big performance hit?
I would think you would have to do that with multiple statements which is in turn more network traffic.
We try to do as much as we can with minimal hits to our DB because we have some users that are on very slow connections.
Thanks for the ideas and look forward to more.

I do have another question.
As you can see we try to do as much logic as possible in the SQL so that we do not have do manipulate the dataset once it is returned....
Because from my understanding the server will be able to optimize much more efficiently than you will most likely be able to do in your program.
For example rather than retrieve first and last name then concat as needed for the result just write it into the SQL so that your result set will already be correct.

That is definitely reasonable, however you need to make a judgment call on how much formatting you do in the query. EG you may note the guy who wants to add CRLF to the data in the query, this is totally invalid whereas concat of the names is good.

It also depends on the volume of data you are delivering, if you are doing this profile for 1 patient then this query is almost valid (I would still split it out for support reasons) doing this for 1000s is not valid.

Why would the number of clients really matter if your indexes are correct?
I understand that the record set has an affect on total time but I don't see how that really relates to a CONCAT for example.
If you are going to have to CONCAT last and first name on 1000 clients what benefit would you have from doing it locally instead of the server?
Also in either case the concatenation I think the concatenation would be happening in memory so in theory the server should have more...
and I would think that the CONCAT statement written in my case mySQL is probably more efficient than the equivalent code in .NET.
Thanks for your thoughts I do appreciate your input just want to have a full understanding of your reasoning.
