Actually, it isn't. I've seen the database report in Enterprise Manager so many rows for a table, but if I do a SELECT COUNT(*) FROM TableName in the Query Analyser I get a different result. This is because the database statistics haven't been rebuilt recently so some parts of the database are operating on out of date information. This does not affect the results of a query (it will always be accurate based on the current state of the database) however, out of date statistics can slow down the database as the query optimiser may choose an incorrect query plan.

We have an app made in C# which promtes users for a sql query at run time, this has become difficult for the users but we were thinking of an easy to use query builder to integrate & instead of writing from scratch we were were wondering if there were available tools to use ??
|

I do not know of a query-builder per se, but at one time we had to generate reports where the functionality would be similar to what you want to do. But like you said, it is difficult for users to write full blown queries, and not only that but you could also run into security problems...
The solution we came up was using templates (SQL Server 2000)...where we had multiple queries defined and users would click on the the most appropriate report type, enter some parameters and bingo, get a report back. A template might look like this:
<?xml version="1.0"?>
<data xmlns:sql='urn:schemas-microsoft-com:xml-sql'>
<sql:header>
<sql:param name="fieldid">0000</sql:param>>
</sql:header>
<sql:query>
Select CustomerName 'name' From dbo.Customer where gender = @fieldid for xml raw
</sql:query>
</data>
This would return the data in xml format (dat as root) - which can be routed through xslt to output nicely formatted result (text/html etc).
This is just an idea - I am sure there are other options out there. This worked well for us as we had more control over every aspect and we could add more "reports" as needed by users. Let me know if you want to pursue this option and I'll point you into the right direction.

i have a database in access, and need information from one table, to be displayed based on textbox value. I have tried repeatedly, and just cant get it. Here is the problem all help greatly appriciated.
database: upsdb.mdb
table: calpackage
columns: sm_trackingno, sm_referencetext0
I am trying to pull the referencetext0 and display as a label with the following:
select sm_referencetext0, sm_trackingno from calpackage where sm_trackingno = txttrack.text
label.text=sm_referencetext0
TIA
|
|
|
|

I hope that's pseudo code.
SqlCommand cmd = new SqlCommand("SELECT sm_referencetext0 FROM calpackage WHERE sm_trackingno = @trackingNo", myConnection);
string result = cmd.ExecuteScalar();
label.Text = result;The above code assumed you already have a connection called myConnection and it is open.
Does this help?

Colin's answer was more or less correct. Since you are using Access, you need to use the OleDb* classes.
using(OleDbConnection conn = new OleDbConnection(connString))
{
OleDbCommand cmd = new OleDbCommand("SELECT sm_referencetext0 FROM calpackage WHERE sm_trakingno = ?", conn);
cmd.Parameters.Add("param1", txttrack.Text);
label.Text = (string) cmd.ExecuteScalar();
}For the connection string for your database, check http://www.connectionstrings.com[^], but it should look something like this:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;User Id=admin; Password=;"

Hello friends!!!!!!!!!!!!!
I expand "Management"
then I expand "Current Activity"
then I expand "Locks / Object"
in the tree on the left side (not the opened window) I see a list of
databases and the objects in each database currently with a lock placed on it.
Most of the listings in this tree are something like:
Northwind.dbo.Categories
but what I'm seeing for one particular database is something like this:
Northwind.jdoe.Categories
Normally I make all objects owned by dbo, however I have some systems that
require another user to be the object owner. such example. However the owner of all the objects is not this "jdoe", but
let's say "jsmith". In which case I would expect the tree listing the
objects being locked to look like this:
Northwind.jsmith.Categories
NOT
Northwind.jdoe.Categories
especially, as I stated previously, since jdoe is just a valid user in
the db.
So, I'm still confused..
How could I remove this jdeo????????????????????
I will remove him by sp_changedbowner.
but why and how that 'jdoe' comes in picture!!!!!!!!!!
Is there any perticular command or login type work because of
that 'jdoe's' name came into picture?????????????????
Help Me Out!!!!!!!!!!!!!!!!
Regards
shashank

1 you can create a proc first like:
create proc p_pic_i
@filename nvarchar(100),
@filesize int,
@jpgdate image
as
insert into pic (
filename,
filesize,
filedata)
values (
@filename,
@filesize,
@filedata)
if @@rowcount = 1 and @@error = 0
return @@identity
else
return -1
go
2 then write a function to call this proc, sorry this is c# not vb.net
public int csf_p_News_ext_i(
string filename,
int filesize,
byte[] filedata,
SqlConnection conn)
{
SqlCommand cmd = new SqlCommand("p_News_ext_i",conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@RETURN_VALUE",SqlDbType.Int,4);
cmd.Parameters["@RETURN_VALUE"].Direction =
ParameterDirection.ReturnValue;
cmd.Parameters.Add("@filename",SqlDbType.NVarChar,200);
cmd.Parameters["@filename"].Value = filename;
cmd.Parameters.Add("@filesize",SqlDbType.Int,4);
cmd.Parameters["@filesize"].Value = filesize;
cmd.Parameters.Add("@filedata",SqlDbType.Image);
cmd.Parameters["@filedata"].Value = filedata;
int retvar = -1;
try
{
conn.Open();
SqlDataReader reader = cmd.ExecuteReader();
retvar = (int)cmd.Parameters["@RETURN_VALUE"].Value;
}
catch
{
retvar = -1;
}
return retvar;
}
3 read stream(asp.net)
Byte[] FileByteArray = new Byte[filelength];
Stream StreamObject = UpFile.InputStream;
StreamObject.Read(FileByteArray,0,filelength);

asp.net,
try
{
SqlDataReader reader = this.oCon.GetReader(
@"select filesize,contenttype,filedata from file_personal
(index=pk_file_personal nolock) where fileid = " + e.Item.Cells[5].Text);
this.Page.Response.ContentType = (string)reader["contenttype"];
this.Page.Response.AppendHeader("Content-Disposition:",
"attachment; filename=" +
HttpUtility.UrlEncode(e.Item.Cells[7].Text));
this.Page.Response.OutputStream.Write((byte[])reader["filedata"],
0, (int)reader["filesize"]);
this.Page.Response.End();
}
catch
{
this.Page.RegisterStartupScript("",
"alert('error!');");
return;

Hi there!
I have a activex dll written in vc++ 6.0
There is one function that needs to receive a Ado Recordset from a VBasic application. It seems that after the VB does the call to the function, the ADORecordset loses at least one property: Sort.
The function is receiving the ADORecordset as an IDispatch.
Any ideia is a good idea to this problem...
Thanks in advance.
