If you have visual studio installed, then you can generate reports through there.

I can't update my a record because when i run my program, my program stops when i click the update button. A dialog box appear and it says:
An unhandled exception of type 'System.IndexOutOfRangeException' occurred in system.data.dll
Additional information: There is no row at position 10.
My codes for the update button is:
<font color=blue>DataSet21.studentsubjects.Rows(ctr).BeginEdit()</font><br />
dr("grade") = txtgrade.Text<br />
DataSet21.studentsubjects.Rows(ctr).EndEdit()<br />
OleDbDataAdapter2.Update(DataSet21, "studentsubjects")<br />
MsgBox("The grade is recorded")
Is there anything wrong with my codes? The error is maybe at first line? How can i correct this?

|

Check whether the
DataSet21.studentsubjects.Rows(ctr) is not null...
before you do the edit!!!!

Ah ok., it means that all my records have already data and not null, thanks...
|
|
|
|

Simply, you dont have record at position 10

ok, thanks. i already put a data in each record so i can already update it but the problem is, the data that i enter goes in other row instead of the correct row.
Example:
my table goes like this: i have 3 fields-
1. ID(primary key)
2. Studname
3. grade
i have 4 records:
The 4 studname are- 'rissa', 'kristine', 'cherry', 'glenda'
i have to enter a grade for each. The data written in their grade is "no yet grade" so that it can't be null.
i search ID '1' which is for 'rissa', then i enter a grade for 'rissa which is '95', but the grade goes in the record of 'kristine'
what is the problem in that? how can i correct?

1. Drag one label in your form and name it lblID
2.In your GridView1 selectedIndexChange event (I am giving this example for asp.net) set text of selectedrow and specify cell's text then set text to lblID.
(In this case select row which contain name Risa)
lblID.Text = GridView1.SelectedRow.Cells[1].Text;//Instead index 1 in Cells property can differ from my example
3. In Update button set update command :
" Update YourTableName set Grade='95' where [ID]='"+lblID.Text+"'";
4.Then bind GridView1.
GridView1.DataBind();

I'm developing a record keeping s/w for retirement plans.There are two user catagory;Plan Sponsor & Participant;each having unique id Ps_id&Emp_id.Only if he has a Ps_id or a Emp_id he can register into th site.
When he enters his catagory id, Register_btn has to check for this id in Plan Sponsor details and Employee details.If any of the table contains the id,then only he can go to th registration page.
Hw can I perform th checking for th catagory id in two different tables;Ps_details & Emp_details?

If exists( (select query with where clause for 1st table) or (select query with where clause for 2nd table))
----implies that there is a record according to the condition in either of the tables.

Hello all,
I have an old C++ program that uses sql2000. Now I need to migrate the database to sql 2005 express. I don't have access to the program fonts.
The thing is that this program creates some tables with names such as "S7:[PLC1|VFD1|S7online]DB118,B28,1" (yes, all of that...). Now, after the installing sql2005, the C++ program can not create the tables any more, displaying the message:
CADORecordset Error
Code=80040e14
Code meaning=IDispatch error#3092
Description=An object name or column is missing or empty. Verify is all the columns of the SELECT INTO instructions have names. At the other instructions, search for empty alias names. Alias defined as " " or [] are not alowed. Add a name or unique space as a alias name.
I've tried to set the compatibility mode to sql80 using the
"EXEC sp_dbcmptlevel dbname, 80" instruction. After that, the error message has stopped, but still no tables are created.
I actually can create a table with the name "S7:[PLC1|VFD1|S7online]DB118,B28,1", executing a "create table" at the management studio. But I can only creat it if the table name is between doble quotation marks ("). I suspect that the C++ program puts the table name between single quotation marks ('), or no quotation marks at all. If I try in this way at the management studio I get an error.
Anybody have any ideas of how I can make this work whitout changing the C++ program??
Thanks
Peterson

If it's stored as a plain string in the original app you might be able to use a hexeditor.
Another option is asking over on http://forums.microsoft.com[^]. They're normal pretty good over there.

Ok, now I´ve manage to solve the inicial problem. The problem was with the sql2005 instace name, and I figured out how to change the connection string.
The c++ program created the tables, but now when it tries to store any data, I get an "SqlException: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value" error message.
When I change the connection string to connect in the sql2000, everything works fine. I tryed changing the windows regional settings, but nothing happened...
Any ideas?
Thanks

I improved on an application that was found on this site (OQuery). I made it so that it could access different types of DBMS such as MySQL, Oracle (which is originally did), MS-SQL 2000. I had two people ask me if I used ODBC which I replied that I used ADO.
I'm a little confused because now I'm having trouble with the differences between ADO and ODBC. I thought ADO ends up using ODBC....right?
I've also heard that an ODBC connection is 10 slower than that of ADO....can someone confirm this. And should I be using ODBC?
Thanks

Yes, ADO is a wrapper to ODBC. But I think you really mean ADO.Net?
|
|
|
|
|
Yes...ADO.NET. So why am I being asked if I used ODBC. Is there some ODBC secret that's not being shared that I should know about?
Thanks

lol, not at all. ODBC is very old and low level. ADO.net, however, is a new(er) implementation for data access and pretty fast. For one, it allows for disconnected datasources which, in itself, is much more efficient for the server (server doesn't have to manage connections). Perfect for web apps. ODBC was used more for the old client/server connected model.
It almost sounds like you're being asked about ODBC because the datasource they want to use doesn't have an ADO.NET connector available?
|
|
|
|
|
That's possible...although all of the options that I've added to my app have a .NET connector.
I'm also wondering is they are asking that because have a different provider for each type of database is not really important.
Between you an Mike, you'ver really cleared this up....now I look and sound smarter.
Thanks

ADO is a wrapper for a technology called OLE DB, although it has little to do with OLE (Object Linking and Embedding). The database-specific layer (called a Provider) is a set of COM objects which implement interfaces designed by Microsoft. The client talks directly to the OLE DB provider with no intermediary. ADO is a classic VB-friendly wrapper for OLE DB.
ODBC (Open Database Connectivity) is based around a manager/driver model. Applications talk to the ODBC manager, which talks to the drivers. The extra overhead is generally minimal. ODBC is the ANSI standard interface defined in the SQL standard.
To enable transition to ADO/OLE DB from ODBC, i.e. so that client application developers could use the new interface before the database developers released OLE DB providers, Microsoft made a special provider called the OLE DB Provider For ODBC available (its ProgID, which you specify in the Provider connection string parameter, is MSDASQL). You should only use this where there is no native OLE DB provider. This provider adds extra overhead and implements a reduced feature set compared to native OLE DB providers. Unfortunately it's also the default provider - it's what you get if you don't specify a Provider in the connection string.
The relative speed of ODBC and ADO is all down to the provider and driver, but in general, all else being equal, ADO should be slightly faster than ODBC if you're using a native OLE DB provider.
ADO.NET is slightly misnamed in the .NET Framework. It's really a general umbrella name for 'how .NET does data access'. The desktop Framework ships with four Providers (the name is the same but the concepts have changed) - two generic (OLE DB, ODBC) and two specific (SQL Server, Oracle [since 1.1]). You can also obtain third-party Providers. The cost of calling a COM object is slightly higher than calling a 'flat' API like ODBC in the .NET Framework, so OLE DB's small performance advantage is mostly negated.
You can access a third-party database like MySQL either through a native .NET provider or via an OLE DB provider (using OleDbConnection) or ODBC driver (using OdbcConnection). Generally you should prefer a native .NET provider as it's likely to have more features and less translation.

Wow.....thanks for the great explination. Okay so if the database creator....for better use of the word....provides a .NET provider then it's best to use it. And if I wanted to add an "Other Database" option to my program...I can always use ODBC to connect to the "Other" database and run a query.
I guess the great thing about ODBC is that I would not have to install all the providers for each of the different types of DB's out there. So now I understand why I keep getting asked if I'm using ODBC.
DING....the light came on

It's worth knowing that the native providers, e.g. the SQL Server providers, generally use the databases native API, so you get the best speed because they aren't dealing with the plumbing that technologies that ODBC put in place.

Hi,
In SQL Server, for seeing the table structure, we use the query sp_help <tablename>. Is there anything similar in Sybase like this? Pls help.
Thanks
Meeram395

The Sybase equivalent is "sp_help <tablename>". At one time, MS SQL-Server and Sybase SQL-Server (or whatever they call it these days) used to have the same code-base and system catalog tables.

To get the list of columns and their types with any SQL database I get an IDataReader for
SELECT * FROM table, then I simply call its GetSchemaTable() method (I don't read the data).
