A better approach would be to take a hard look at the table design, and see if you can split the table into several smaller ones.
Text (or NText) columns can't be used in 'Like' queries (you would have to use ful text search) and they will introduce a performance hit, since the data is stored in a binary tree rather than in the table (the table will only contain a pointer to the root of the tree). this results in at least one additional disk IO for each field returned (possibly more if the field was large, and had to span several allocation nodes on the storage tree).
Certainly you have more data per row than can easily be displayed, so I would think multiple tables with a common foreign key would work.

Thanks all.
I agree to the idea of spliting the table with foreign Key relations
than changing to text fields.
thanks again.

Try the Data Transformation Services import/Export wizard of the sql server and choose the correct data source.
Does it work!

Hi,
Anyone got source code to change SQl Server startup account to SA.
I need this to be run in my installation.
VB script, java script or installscript will be very helpful.
Thanks

Help me
I have a trouble again with M.Access. I have a combo-box on a form, and this combo-box has the responsibility on showing the Query which creates the 4-column table, including Company,Name,Address and ClientID.
My purpose is that I want to show this Query in the combo-box in the order A-Z, before the blank company items.
My solution:
I create a query like below:
select .........
from nhanvien
where company is null
union
select .........
from nhanvien
where company is not null
However, the result isn't right like my hope. I think that the reason is because of the order of the ClientID which is the primary key...As a result, the destination query automatically sorts on the ClientID order.
Thinking of the solution :
I don't know how to do to archieve that result. I think so much about the SQL sentence of the above query. I believe that there's another SQL sentence helping me to solve this problem. I'm very happy whether you give me a SQL sentence to do that or another solution to obtain the same result ....
Thanks so much <vtalau>

Select Company,... from nhanvien where company is NOT NULL<br />
Union<br />
Select Company,... from nhanvien where company is NULL<br />
order by Company ASC<br />
<br />
This wont quite accomplish what you wan, the null values will sort to the top, not the bottom, but at least the non-null values will be sorted a-z for you.
an alternative would be to do this in two steps:
selecting all the not-null records first:
<br />
Select Company,... from nhanvien where company is NOT NULL order by company ASC<br />
and add the records to the combo box
then add the remaining values with a second query not sorted
<br />
Select Company,... from nhanvien where company is NULL <br />
and add the results to the combo (don't clear the first set of results)

The most obvious question is, can you see that folder on your network from that machine, without having to log in to it ?

The user that your site runs under needs access. When you're browsing, you're not doing it as that user. How is the site written ( asp/asp.net/etc ? ). Do you know the user your site runs as ? Does IIS allow anonymous access ( if so, you're probably running as an anonymous user ).

The SqlConnection[^]class is your starting point, you should find all the example code you need for the database connection stuff from that link.

I have some troubles with M.Access. I want to create the calendar control on a form of my Access database like the calendar control of vb.net or C#. However, I can't find the way to do that .Thus, I'm very happy if you help me...

You have insert the "Microsoft Date And Time Picker Control". Usuary it's at the tools floating window, if it isn't, you'll have to search for it in "ActiveX Controls" in the Tools menu. Usually, it's available, but it depends on your Access installation.

is there a way to join two tables from two diffrent odbc data sources (or joining to dataset tables) ..any ideas?
|
|
|
|
|
Yeah it's easy 
To create a relationship between 2 datasets create a datarelation. Look in the Visual Studios help index for datasets, relationships
Thier example is as follows.
Dim CustomersOrders As New DataRelation("CustomersOrders", _
DsNorthwind1.Customers.Columns("CustomerID"), _
DsNorthwind1.Orders.Columns("CustomerID"))
DsNorthwind1.Relations.Add(CustomersOrders)

I am using VC++ dot NET, and am trying to use GetRows to populate an array with the rows from one of the columns in a table. My adodb recordset contains the data. I know the recordset has
200 rows in one column, so I have:
float data[200]; <br />
data = p_myRecSetPtr->GetRows(-1);
and I get the error: "error C2440: '=' : cannot convert from '_variant_t' to 'float []'"
I tried casting the result but couldn't get it to work right.
Does anyone know how to solve this problem? or possibly what cast I need to use?

|

Yes, you need to do this:
_variant_t vt = p_myRecSetPtr->GetRows(-1);
You can't magically change what the function returns. It's probably a SAFEARRAY, which has a nice wrapper class, called CComSafeArray from memory.
