I can see you've just not translated some Java properly. You should also be aware that Java and SQL are different language types. Java is procedural (i.e. you specify the procedure you want it to take) where as SQL is, for the most part, declarative (i.e. you specify what you want and it figures out the details) - but SQL can also operate in a procedural way also but that is often very inefficient. The procedural elements exist only to suppliment the declarative (set based) elements. If you can use a set based operation then SQL is very efficient.
What you are doing here is imposing a procedural model.

I have written a SQL script to run from my code using executesql command..meaning that i have framed the sql script and have it in a string and i pass the string to the ExecuteSQL funtion which executes my sql script..my scripts functionality is to insert some 1000 rows into a table..when my code executes the script runs(which i came to know from profiler) but the rows are not inserting..
can anyone tell me as wat could be the reason??
NOTE: there are no conditions in the script that ll prevent the insertion happenning
its a bit urgent..
thanks in advance..

I suspect there is an error in the script.
Best regards,

any other clues pls let me know..

Just for another thought, if you are using MSSQL 2000 there is a limit of 4000 characters for nvarchar (unicode 'wide' varchar) and 8000 for regular varchar.
Your string may be longer than that and as a result it gets truncated when passed to a stored procedure.

I'm trying to force a window to jump to a specific row in my database when I click a button. I'm using a "details" display of the table, and there is a binding navigator(supplied with the drag and drop creation of the form).
An example would be (I'm using c# btw)
[Parts list]
1.
2.
3.
...
Select Part [2.]
New Form with more details on part 2.
Edit/Delete/New part
I can use a modified SQL query to return just the one row, but then the add/delete/new buttons dont work because the mapping is lost to the original data. I can't imagine this is something hard to do, but I've been all over the net posting for an answer and nobody has even attempted. Any help is appreciated.

I found this article here[^]
I've tried to follow because that sounds like my problem, so my code looks like this.
this.tbAdapter.fill(dataSet.tb);
this.dataSet.tb.select();
that still gives me record 1, instead of the one I want. What am I doing wrong?

Hello again PyroManiak,
I took a quick look at the code in the link you gave, and I noticed that the poster in that message was using the IndexOf function, which he said was returning -1. The way I understood his reply post with the answer was that he called select but then called IndexOf after that. This is just speculation, since I haven't tested it yet, but I wanted to ask you if you were calling IndexOf?
If you are and it still doesn't work, could you post the rest of your code to do with loading the "edit" form?
Hope that helps.
Sincerely,
Alexander Wiseman

I think I've got a solution. It seems to work without problem.
myBindingSource.Position = variable;

My older post got answered in a rather rude way, thanks for not treating me like an idiot.

Don't suppose you know how to capture a single attribute from a row in a datagridview do you?
-- modified at 19:57 Tuesday 27th June, 2006
I'm trying things like datagridview.rows.indexof();
but it says I must give it a variable, well, if I had the variable I wouldn't need it to tell me! =P

I'm sorry, its probably just me. It is the end of the quarter and this project was dumped in my lap as a last minute deal and it wasn't planned out other then some oddball requirements. As far as a book goes, I'm been waiting to get a book on ADO.net 2.0 (Pro ADO.NET 2.0 - Sahil Malik) but they wont budget anything else until next month when the new quarter kicks in.
This is what happens when people find out a hardware engineer also has background in software development.

I have an app with a DAL and so far I have been calling sprocs that require no input parameters and all works fine. I now have to call a sproc with requires an input paramter. The sproc I am calling is as follows:
ALTER PROCEDURE dbo.prc_QA_SysCodes_sel_drop_fill
(
@sysCodeType as int
)
As
BEGIN
DECLARE @Err Int
SELECT
A.[SysCodeID],
A.[SysCodeDesc]
FROM
[Contract].[dbo].[QA_SysCodes] A
WHERE
A.SysCodeType = @sysCodeType
order by
A.[SortOrder],
A.[SysCodeID]
Set @Err = @@Error
RETURN @Err
End
I need to pass in the @sysCodeType but can't figure out how to pass it to the sproc. Thoughts, words of wisdom?

Add parameter to your procedure:
yourSP.Parameters.Add(ParamName, SqlParamType, length); //length is optional
Pass value to the param
yourSP.Parameters[ParamName].Value = ParamValue;

Hi
I can execute single line statements against a db, no problem...
string SQLQuery = "select VERSION, DSC from exo_version where SYSTEM = 'DATABASE'";
string strConnect = "DSN="+ dbName +";UID=abc; PWD=cde";
OdbcConnection conn = new OdbcConnection(strConnect);
conn.Open();
DataSet fullSet = new DataSet();
OdbcDataAdapter dataAdapter = new OdbcDataAdapter();
OdbcCommandBuilder commandBuilder = new OdbcCommandBuilder(dataAdapter);
dataAdapter.SelectCommand = new OdbcCommand(SQLQuery, conn);
dataAdapter.Fill(fullSet);
Cache["dbVersion"] = fullSet;
but my client wants a web based front end developing where the user can dump a load of statements in one big text block, select the DB and the server to execute them.
The 'old' way of doing this was to open up PLSQL, paste the script into a command window and execute. I could parse the text for the semicolon and process each line independantly, but is there a way to throw a whole script, which will include inserts, deleted, modification of schema, index creation etc at the database in one go?....and then capture the output!!
Any info at all on this would be appreciated.
Regards
Angel

You need to know what the fields are in the other database.
