Absolutely. Ok, for my 2 cents worth I think you need to look at what you are asking. An SQL statement is returning a recordset to you, you however just want to modify the display. While manytimes "modifying" the display of a recordset can be easily done within the SQL statement itself, manytimes this is not the route to follow. What I am getting to is if you iterate through the recordset and throw the values into an array structure you can easily display your output as you want (from the array) it without modifying the SQL statement at all. What language are working with? Does this help at all?

Here is a resultset:
ID Name Value
---------------------------------
101 Name1 Value1
101 Name2 Value2
101 Name3 Value3
101 Name4 Value4
101 Name5 Value5
101 Name6 Value6
could anyoane tell me a way that could transform the above resultset in something like next one? (I'd prefer an SQL approach / not cursors and so on... but i appreciate them anyway)
Name1 Name2 Name3 Name4 Name5 Name6
----------------------------------------------
Value1 Value2 Value3 Value4 Value5 Value6

Greetings,
I recently created a table which has a datetime varible which stores the date and time such as this "11/18/2002 1:30:33 PM".
But now I want to have milliseconds stored in this as well, such as shown below.
"11/18/2002 1:30:33.33 PM".
By default it does not allow me to add the ".33", so I am assuming it is just a formating setting when I create my table, but I am not sure how to do this? Any suggestions on how to do this?
Here is a sample section of my code of how I create my table with the date, and how I do insertion of the data. I am using sql server 2000, and ADO via Visual C++ 6.
CREATE TABLE MyTestSql
(
MyTestDate datetime
}
INSERT INTO MyTestSql(MyTestDate)
VALUES('11/18/2002 1:30:33 PM')
Thanks in advance for help?

Greetings,
As usual if you work on something, right after you make the post you find the solution to your problem.
It seems that microsoft sql server rounds up the time value's millisecond, so that it doesn't show up in the database. It had nothing to do with formating the date and time.
Here is a link that explains a solution on how to get your milliseconds back.

Hai all,
We have a sql server table (which contains a Guid col + others). For processing the data in this table (about 0.1 million records a day), we move the data to access db on the user's desktop.
Currently we are using ADO to access the sql server and update the local access db (using batch update). It takes about 10-15 minutes for the whole operation. Is there a faster way to do this ? We have a requirement to move records from SQL to access based on certain filter criteria .
Any pointers will be greatly appreciated

Have you looked at DTS? I'm not sure if it'll be any faster but I use it a lot to move data from one place to another.

As Michael suggest, use DTS. It will work (with filtering and all sorts of other options) but you won't have any fun. DTS is painful IMO.

I am trying to (re)write a knowledgebase, cuz it sux a$$.
Anyways...I have a keywords field in the database and the user enters keywords into an input field.
The code constructs a query which looks something like this:
SELECT * FROM kb_articles WHERE Keywords LIKE '%Show%' OR Keywords LIKE '%Me%' OR Keywords LIKE '%the%' OR Keywords LIKE '%money%'
I'm not a whiz at SQL so i'll explain myself here a little incase my syntax if off or something...
Obviously i'm selecting records from a table called kb_articles which has the following structure:
PKID | Question | Answer | Keywords |
Keywords and Answer should be searched for potential results. As far as I can tell, the above won't work (i'm using mySQL BTW) because LIKE chokes on multiple words.
Example?
Question entry page:
Question: How can I make lots of money?
Keywords: Show me the money
The script then parses Keywords and Questions into individual array elements (seems logical) and those items are what get compared to each record inside kb_articles keywords field. Only the keywords field can also have multiple keywords and these aren't parsed into indy words, so basically what's happeneing is this:
kb_articles.keywords = "How, To, Show, The, Make, Money"
SELECT * FROM kb_articles WHERE keywords LIKE '%Show%'....
LIKE i think chokes on multiple words inside the database keyword field...
So my question is this...Is there a way I can use SQL regex to compare I have no idea about anything REGEX...  or am I going to have to execute multiple queries constructed using PHP...?
Thanks in advance

That SELECT statement looks like it should work but you will have to put more LIKEs in there if you want a better search. For example, you may want to use LIKE '%Show me the money%' or LIKE '%Show%me%the%money%' or LIKE '%show%me%' etc.

Well,
I can't find out what kind of database uses .idx and .dat files for storage of data. I have tried several ODBC drivers but they won't work.
I hope someone has an answer to these questions,
thanx in advance,
Robert Smit

I've come across several in-house databases that have used those extensions, I've not come across a commercial one with these extensions. Most tend to be of the flat-file variety which usually means no ODBC support.
I have used those extensions for a flat-file database in the past but I doubt you'll be trying to connect to that

Micheal,
Thank you for your answer I think you could be right. It is only a small program that stores data to those idx and dat files. The database is used only for storing pupil en group results for math exercises. So it is not a complicated DB with a lot of stored procedures.
My question to you is how you read and write to those files in C++.

Without the file structures you'll have a hard task.
In the good old days when I used to try and integrate with Pegasus Accounts who used a similar system, I usually saved a record into the database using their app and then hex-edited the file to figure out what had been updated and changed.

Hello,
like subject says, is there something more than setting a password for the database that I can do to make sure that people don't open an MDB file and mess with it?
Thanks!

Hey LukeV,
You may choose to open an MDB in exclusive mode and set password to it. So that each time the MDB file is opened, it will ask password.

Hi.
I've got a basic ADO AddNew call, running in a loop, against Access 2002. Running on VC++6, Win2K, MDAC 6 sp2. See code below.
It seems to use memory constantly, even when the recordset object is released. It uses approx 10MB per 100,000 rows written. My system needs to be on line and writing data for a week at a time so this is going to be a problem for me. Any ideas?
Ta.
Gizz.
The following function is called from another big loop...
void fn()
{
using namespace ADODB;
_RecordsetPtr pRst = NULL;
_ConnectionPtr pConnection = NULL;
_bstr_t strCnn("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\data.MDB");
try
{
TESTHR(pConnection.CreateInstance(__uuidof(Connection)));
pConnection->Open(strCnn,"","",adConnectUnspecified);
TESTHR(pRst.CreateInstance(__uuidof(Recordset)));
pRst->Open("tblMyTable",_variant_t((IDispatch *) pConnection, true),
adOpenKeyset,adLockOptimistic,adCmdTable);
_variant_t strGBID("GBID");
_variant_t strTSID("TimestampID");
static long i = 0;
static long imax = 1000;
for (;i < imax; i++)
{
pRst->AddNew();
{_variant_t vtFld;
vtFld.vt = VT_I4;
vtFld.lVal = i;
pRst->Fields->GetItem(strGBID)->Value = vtFld;}
{_variant_t vtFld;
vtFld.vt = VT_I4;
vtFld.lVal = i+1;
pRst->Fields->GetItem(strTSID)->Value = vtFld;}
pRst->Update();
}
imax += 1000;
pRst->Close();
pConnection->Close();
pConnection.Release();
pRst.Release();
}
catch(_com_error &)
{}
}

I don't know where is the problem,But about pConnection.Release(); and pRst.Release(); I have to say you don't need them because you use these inrefaces as an pointer and they will release automaticlly. But you problem MAYBE because of access,I know it has limitation on number of records,and after you insert 100,000 rows in a table in crash or ....You didn't which line cause memory leak!

Hi,
I am new to database programming in c++ and come across some quest. which i can't find in books.
I am programming in c++ mfc platform, using ADO to access to the sql database.
However, my database is using MS windows 2000 Terminal Services Web Connection
and i don't know how to link to the database. In Short, how is the connection string parameters to be like.
Thanks

Creating a database this way:
if( database.OpenEx(sSql,CDatabase::noOdbcDialog) )
{
sSql.Format( "CREATE TABLE Sounding ([Pressure (mb)] FLOAT,[Height(m)] FLOAT)");
database.ExecuteSQL(sSql);
sSql.Format("INSERT INTO Sounding VALUES('%f','%f')",mPressure,mHeight);
database.ExecuteSQL(sSql);
....
If mHeight is 17.60 it is inserted 17600000, if I change to '%.f' it is inserted 17, and if '%.2f' 1760. What is the solution to insert the right decimals?
Thanks.

There are two point here:
1.Are you sure that mPressure and mHeight are float value or maybe you define them as int.
2.It could be in your database.You set the Scale of it tp 0.Its is zero by default so you forgot to change it,So SQLServer or access omit them.

Yes, mPressure and mHeight are float values.
How could I change the default Scale?
Thank you.

Do you use Access or SQLServer?

Well, I'm using it into an MFC app, with Visual C++, and getting the ODBC Microsoft Excel Driver. It´s the first time I include a database utility in an applicattion, so I don´t know exactly what I'm using. If it helps, I use Cdatabase class with function member ExcecuteSQL.
Thanks.
