Easiest Way To Get Data From Sql To Textbox

Jun 17, 2008

Hi I have a situation where i have a drop down list. The user selects a value from it and then a query behind the scenes is generated based on the value from the list. I want the result of the query to be diplayed in the textbox.
I've checked a few examples but i don't really have a good understanding of how to generate this query and get the results to the textbox. I think you use the SQLDATASOURCE but still need some help...Can anyone help?
Thanks.

Easiest Way To Import CSV Data Into A Table?

Apr 30, 2006

Hi, I'm new to SQL Server, and would appreciate some advice on the quickest way to import data from a CSV file.

I've created a database using Visual Web Developer Express, and added a couple of tables. The Help file in SQL Server Express (which is installed on the same PC) indicates that I should use BULK INSERT to populate the table. Only snag is, I could find anywhere to enter the commands! Eventually, I found out about the SQLCMD command which I entered in a Windows Command Window. I successfully connected to the default (SQLEXPRESS) server instance this way, but when I typed USE <my database name> I got an error back saying it couldn't find the database. I know that Visual Web Developer Express by default creates user-specific instances of the database, but I've turned that off (I think!) via the connection string. So, please could someone tell me how I can connect to my database via the SQLCMD command, or alternativley please let me know how else I can bulk inmport data from a CSV file. Many thanks in advance.

Easiest Way To List All Data Sources Servers?

Dec 1, 2007

SQL Server RS 2000 SP4

I'm trying to find the easiest way to get a list of every data source on a RS instance, including the name of the SQL Server that the data source points to. We want to make sure none of the data sources point at our primary OLTP server.

I looked at the DataSource table in the ReportServer DB, but of course the connection string info is encrypted. I'm hoping that I don't need to resort to writing .net code to hit the web service.

TIA,

-Peter

Data Alignment In Textbox

Feb 26, 2007

Hi All,
I am working on a report, in this report a textbox is present, which is expected to show string. This string length is larger than what textbox can accommodate in single line. I want this textbox to show only right part of the string in case it can accommodate full string.
After using the right alignment I assumed it would do show, however it does not work like that. It always shows the left part of string in case, string is bigger than width of textbox.
Restriction from design:
1. Cannot increase the width of textbox.
2. Cannot use the Can Grow = true to show string in multiple lines.

Below is the example of my issue:
Say there is a string: "Microsoft SQL Server Reporting Services".
because the textbox width is not sufficient to see full string, I want to "Reporting Service". Which is of same size which column can accommodate. So I used Right alignment in textbox. however text box shows "Microsoft SQL Server". So, is there a solution to see required text in the textbox.

Computing And Assigning A Value To A Textbox From Other Data Regions

May 18, 2007

I am new to SSRS, so perhaps its a trivial question. I was wondering that since all controls have names in the report, is it possible to programatically access values of different textboxes, do some computation and then assign to another text box? I know how to do it using the Aggregate functions and operators, but am not sure if I can access values from textboxes within two different tables and assign the computed value to a third text box on the page (not belonging to any table or other control).



somethig like.... txtTotal.Value = FormatCurrency(txtSalesTotal.Value) - txtDiscount.Value));



Any ideas??

Easiest Way As I Intended

Hi guys how are you doing? I was wondering how should I set the values in these two variables without making the select, I mean just set, I think that if I select two times it takes much longer is that true?

declare @user_id int, @creation datetime

select @user_id = user_id, @creation = creation from solarUsers

Select @user_id, @creation

Thank you very much =D.

Reporting Services :: Change Visibility Of Textbox (Tablix) Based On Data From Two Datasets?

Jun 11, 2010

I have two charts which are based on their own separate datasets.  One chart shows data aggregated by MONTH, the other chart shows data aggregated by WEEK.  I have put both of these charts inside a rectangle and set their visibility based on whether or not there is data returned by their respective datasets.  This part is working just fine.

However, I have added a tablix to the report, deleted all columns and rows leaving only one remaining row/column so it looks like a textbox.  This tablix is sitting on top of the two charts.  The problem i'm having is that when both charts return no data and they do not show up in the report, the tablix still remains visible. I need to set the visibility but based on a condition between the two different datasets behind each chart.

Here's what I need:  If ONE of the charts returns data, then I need the tablix to be visible.  If neither chart returns data, then I need the tablix to be invisible.  I'm trying to write an IIF statement comparing the two datasets but I get inscope errors.  Isn't it possible to compare values which are contained in two separate datasets in SSRS?

Seems like something like the following logic should work:

IIF(CountRows("Monthly_DataSet") > 0 OR CountRows("Weekly_DataSet") > 0 , FALSE, TRUE)

Obviously the above expression will return syntax errors, but you'll get the point as to how i'm thinking. How can I set the visibility of the tablix based on these two charts?

Best/easiest Way To Search A Table In A Database?

Aug 9, 2004

im pretty new to SQL and i'm just reading up on full-text searches... i need to do a a full-text search on one table i have in the database.. however I'm reading about full-text indexing/searching and a lot of pages are saying that it uses a lot of resources when searching.. i was wondering how bad is it really? we have about ~100 users who would access the database, probably the peak would be 75 at a time.. would people using a full-text searching slow it down a lot? the servr is a dell poweredge 1750 server, dual 2.8ghz xeon, 1 gig ram.. and also, about the incermental population, if i read right, it populates the catalog each time a item in the table is deleted/inserted/modified.. so would that use a lot of resources as well?

i'm just trying to see if it's worth it to enable full-text indexing for searches on the database if it doesn't slow down the server too much... or are there any better/easier ways to perform searches?

thanks
