Thanks.
I'm keen to do something similar to this:

DECLARE @EntTypeID int

SELECT @EntTypeID=0 --init

SELECT @EntTypeID = ( SELECT [ID] from tblEntityTypes WHERE [Descr]='BLAH')
--do something with the @EntTypeID var.

Anyway to implement this in Access 2000, XP?

Cheers,
Simon

Well, you can have query with parameters and access them from Access Basic, however I do not know how to get functionality as you want within one query. When you will write code in Basic and use several queries then you can simulate your code.

I have a question about CREATE DATABASE in SQL Server2000.It has a parameter named FILEGROWTH and COLLATE.Could someone explain them for me? Thanks.

FILEGROWTH

As you are adding data into the database, more and more space is needed. When used space will reach the size of the file, then SQL Server will extend that file by amount specified in the FILEGROWTH.

COLLATE

COLLATE specifies how you will order strings in the database, depending on selected language. There are different rules to order strings in the different languages.

COLLATE specifies how fields are sorted, and FILEGROWTH specifies the increment in which the file size will increase when needed if the DB has its assocated files set to autogrow.

Here's a snippet from MSDN to give you a better idea about COLLATE...

COLLATE

Specifies a collation sequence for character fields in subsequent indexing and sorting operations. ... Note When you specify the SPANISH option, "ch" is a single letter that sorts between "c" and "d", and "ll" sorts between "l" and "m".

Hello,

I am trying to figure out a way to get different characters from different fields to auto-produce a string to display to a user on a web page. For instance, if you enter your name as John Doe and your SSN is 000-00-1234, then I want to be able to go to the firstName, lastName and SSN fields and get only the FIRST letter of the firstName & lastName and the LAST three of the SSN and put them together and add them to the userID field in the table (i.e. JD234). Right now, the SSN fields are split as ssn1, ssn2, ssn3, and are combined and entered into the SSN field as xxx-xx-xxxx.

I would also like the capabilities of creating an ID based on two different things. For instance, if they supply an employee number INSTEAD of an SSN (we are currently changing our ID naming scheme, but not enforcing it at this time), then I would like to take the FIRST letter of the firstName and the last (6) of the employeeID and create the userID from that...do I use an If...Then...Else to see which they entered and produce the ID? Keep in mind that I want to do ONE of the OTHER, but the new scheme (using the employeeID field) takes precedence. Anybody out there done this before?? Thanks for your help!

Why does it have to be so complicated??

MySQL Has the following core functions:
connect(), query(), store_result(), fetch_[row, feild]() num_rows(), num fields(),
escape_string(), and close()
There are others, but those are the most used.

Data returned is all characters, and and you get to the data by:
row=fetch_row(query_result);
and row[N] = field N, it's that simple!

Is there anything that simple for ADO or ODBC? I'm trying to port a MySQL app to SQL Server, and having a hard time finding anything that simple. My real concern is handling user-defined queries. In MySQL it was as easy as:
con=connect();
query(con, user_sql);
result=store_restult(con);
feilds=num_fields(result);
while (row=fetch_row(result)){
for (f=0; f

Hi

I want to develope an client application to update/retrieve data from a remote database namely SQL on some maching over the Internet. For example, application to connect to TheCodeProject database to retrieve the appropriate data, format it then output it. In the essence, it just acts like off-line forum reader , without having open the browser and offer some extra functionality like saving, attaching files, etc.... However i m still in the dark of how about to do it. I would like to ask some questions related to the matter:

1) Is C# the most appropriate language to do this?

2) What sort of configuration does the MySQL server needs to apply for my application to make a connection?

3) I want to make the interface of the application Outlook liked, how would i do so?

Thank alot for reading this and looking forward to receive your enlightment!

Best Regard

The error message about not being able to install server tools actually means it coudn't install SQL Server. This is probably because you're running a desktop OS instead of a server OS.

You should have a second disk with the Personal Edition on it, which will install on your machine.

SQL Server 2000 Enterprise Edition and Standard Edition run on Microsoft Windows 2000 Server, Windows 2000 Advanced Server, Windows 2000 Datacenter Server operating systems, Microsoft Windows NT Server version 4.0 Service Pack 5 (SP5) or later, and Windows NT Server 4.0 Enterprise Edition with SP5 or later
SQL Server 2000 trial software and SQL Server 2000 Developer Edition run on the operating systems listed above for the Enterprise and Standard Editions as well as on Windows XP Professional, Windows XP Home Edition, Windows 2000 Professional and Windows NT Workstation 4.0 with SP5 or later.

ADO Losing Changes with GetChunk/AppendChunk

I have a table with two BLOB fields...

If I read one blob (using GetChunk), modify, then write back (using AppendChunk), then read the other blob, modify, and then write this back, the changes made to the first blob are lost during the Update...

This can be fixed by reading the two fields and then writing them...

Is this a known bug in ADO/Jet???

(this is running on Win2K, Access Database, Jet4SP6)

Good Database for News Articles

I'm developing a site (under 10,000 more like 5,000 Poke tongue | ;-P

), and I was trying to decide which database software I should use. I want to create a database for news articles. We didn't want to spend the money for SQL or any such software mainly because we are a non-profit organization and money isn't easily attainable. We do have licenses for Access, but is this actually the best way to go? And if you have any software recommendations or if I should try a different approach (not a databse) such as text files for each new article. I know of MySQL, but I am unfamiliar with it. We are using IIS on Windows 2000 Server. Your opinions, please Smile | :)

Thanks very much, Sean

I don't think Access would handle it, in my experience it tends to fall over after about 5-10 simultaneous connections. I understand MS SQL is probably out of range, so you could well look to RDBMS's like MySQL or even PostgreSQL. However, make sure you consider support, with a commercial product you do have someone to yell at when it all goes a little wonky!

On the other hand, possibly consider using the DB as nothing more than a reference. i.e. store the actual news articles in an XML file, and then format these using XSL. You can then store both of these in a table which would reduce the size down, and you could probably get away with the performance. Keeping entire articles in a DB is probably not a good thing anyway, let alone when you're limited to Access!

Updating a value in a Recordset using Find

Mr. Bill12-Jul-02 11:38

Mr. Bill

12-Jul-02 11:38

I have a text file that I am reading in from and want to store the information in a recordset until all the values in the text file are read in. I am using find to find the row to put the value into but once I update a value and do a movefirst I get an unspecified error.

//while
m_pRecs->MoveFirst();
m_pRecs->Find(strTemp.AllocSysString(),0,ADODB::adSearchForward);
if (!m_pRecs->adoEOF)
m_pRecs->Fields->Item["Value"]->Value = strValue.AllocSysString();
//end while loop

I have also tried filtering without success. Clearing the filter gives me problems. I don't want the db that I am using to change so this recordset is essentially just a place holder until the text file is read in and the values are pulled back out of the recordset. Any help will be greatly appreciated.

I put a m_pRecs->Update() and it caused the same unspecified error as the MoveFirst(). Just for my info. Doesn't the movefirst call update if the recordset has changed, I could be wrong that is why I am asking.

Thanks for replying,
Bill

Could it possibly be the way I am assigning the value.

m_pRecs->Fields->Item["Value"]->Value = strValue.AllocSysString();

That is a general field in an excel spreadsheet. I have changed it to text and it acted the same.
