Adding To 2 Different Tables

Apr 19, 2007

Hi Everyone,

I have a page with a textbox and a dropdown list.
The user will enter a company name in the text box and select a number from 1 - 20 (number of delegates for that company) in the dropdown list.

I've got the text box and dropdown writing to tblCompany but I would also like it to write to tblUsers at the same time. The reason for this is that i need it to set up the number of users that have been selected in the dropdown list.

Here is the codebehind file:Imports System.Data.SqlClient
Imports System.Web.Configuration

Partial Class cms_Management_Company_NewCompany
Inherits System.Web.UI.Page

Dim companyName As String
Dim companyActive As Boolean
Dim companyArchived As Boolean
Dim companyDelegates As Integer

Dim userForeName As String
Dim userSurname As String
Dim userEmail As String
Dim userUsername As String
Dim userPassword As String
Dim userActive As Boolean
Dim userTypeID As Integer
Dim companyID As Integer

Dim i As Integer
Dim NoLoops As Integer

Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles btnSave.Click
Dim conString As String = WebConfigurationManager.ConnectionStrings("General").ConnectionString

Dim con As New SqlConnection(conString)
Dim cmd As New SqlCommand("INSERT INTO tblCompany (CompanyName, CompanyActive, CompanyArchived, CompanyDelegates) VALUES (@CompanyName, @CompanyActive, @CompanyArchived, @CompanyDelegates)", con)

cmd.Parameters.AddWithValue("@CompanyName", companyName)
cmd.Parameters.Item("@CompanyName").Value = txtCompanyName.Text

cmd.Parameters.AddWithValue("@CompanyDelegates", companyDelegates)
cmd.Parameters.Item("@CompanyDelegates").Value = lstDel.SelectedValue

cmd.Parameters.AddWithValue("@CompanyActive", companyActive)
cmd.Parameters.Item("@CompanyActive").Value = True

cmd.Parameters.AddWithValue("@CompanyArchived", companyArchived)
cmd.Parameters.Item("@CompanyArchived").Value = False

Using con
con.Open()
cmd.ExecuteNonQuery()
con.Close()
End Using

Dim con2 As New SqlConnection(conString)
Dim cmd2 As New SqlCommand("INSERT INTO tblUsers (UserForeName, UserSurname, UserEmail, UserUsername, UserPassword, UserActive, UserTypeID, CompanyID) VALUES (@UserForeName, @UserSurname, @UserEmail, @UserUsername, @UserPassword, @UserActive, @UserTypeID, @CompanyID)", con2)

cmd2.Parameters.AddWithValue("@UserForeName", userForeName)
cmd2.Parameters.Item("@UserForeName").Value = "First Name - Delegate 1"

cmd2.Parameters.AddWithValue("@UserSurname", userSurname)
cmd2.Parameters.Item("@UserSurname").Value = "Surname - Delegate 1"

cmd2.Parameters.AddWithValue("@UserEmail", userEmail)
cmd2.Parameters.Item("@UserEmail").Value = "Email Address - Delegate 1"

cmd2.Parameters.AddWithValue("@UserUsername", userUsername)
cmd2.Parameters.Item("@UserUsername").Value = "Username - Delegate 1"

cmd2.Parameters.AddWithValue("@UserPassword", userPassword)
cmd2.Parameters.Item("@UserPassword").Value = "Password - Delegate 1"

cmd2.Parameters.AddWithValue("@UserActive", userActive)
cmd2.Parameters.Item("@UserActive").Value = True

cmd2.Parameters.AddWithValue("@UserTypeID", userTypeID)
cmd2.Parameters.Item("@UserTypeID").Value = 2

cmd2.Parameters.AddWithValue("@UserTypeID", userTypeID)
cmd2.Parameters.Item("@UserTypeID").Value = 1

Using con2
con2.Open()
For i = 1 To NoLoops
cmd2.ExecuteNonQuery()
Next i
con2.Close()
End Using

Response.Redirect("~/cms/Management/Company/Company.aspx")
End Sub

End ClassThe other thing I am not sure of is getting the ID of the new company and assiging it to the delegates in tblUsers (to associate them with the new company)I hope this makes sense.Thank you very much guys.Scott.

Adding Sql Values From 2 Tables

Feb 15, 2007

Hello all, i have 2 sql tables, and they each contain a column with bigint values. What i want to do is add up the values from both table, and then display it as 1 number. Supposing i have the following
table name: DownloadTable
fileName | DownloadSize |
file1       | 45
file2       | 50
file3       | 20
---------------------------------------------
 second table
table name: VideoTable
fileName | VideoSize |
file1       | 40
file2       | 60
file3       | 20
----------------------------------------
Now, i want this to output 120, wich is the sum of the sum of the values of table 1 and 2 I've already tried the following:
SELECT SUM(DownloadTable.DownloadSize) + SUM(VideoTable.VideoSize) FROM DownloadTable, VideoTable
However, when i ran this, it gave me a huge number, that was far from accurate from what it was suppose to output. Can anyone help me?
Thanks in advance

Adding Data To Tables?

Mar 6, 2014

I'm currently in an SQL internship, and am running into an issue with a project they've given me. Primarily, he's asking me to try to get a table containing student entry testing information to update with a new column that's supposed to contain the testing dates. This in mind, there is another table that contains testing data, and who's students are grouped by date, the data in each group all coming from the students table. Issue is, I don't know how to get the testing dates from the TestData table into the Students table. There's already a relationship set up between the TestID fields on the TestData table (PK) and the Students table (FK), so I don't think I can set up a new relationship to get it working.

How To Go About Adding Similar Tables?

May 26, 2007

I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.

Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.

I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.

I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.

How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?

Thanks in advance.

Joining Tables - Adding Columns With Criteria

Oct 10, 2013

I have two tables a and b, where I want to add columns from b to a with a criteria. the columns will be added by month criteria. I want to keep all the records in a, and join columns from b. I do not want to loose any row from a if there is no data for that row in b.

I do not know how to have the multiple joins for 12 different months and what join I have to use. I used left join but still I am loosing not all but few rows in a:

/****** Script for SelectTopNRows command from SSMS ******/
SELECT a.[naics]
,a.[ust_code]
,a.[port]
,a.[all_qty_1_yr]
,a.[all_qty_2_yr]

Adding Tables To SQL Server Database In Visual Studio?

I keep reading it's possible to add, amend ,etc. tables in visual studio but to do so I need access to the features that allow this.
I can connect to the database but I haven't been able to use any of these database features since they are "blanked" out.
Obviously, I can do all this at the server but ideally I would like to do it remotely.

Any suggestions?

Adding A Full Text Search Across Multiple Tables (with Text Fields)

Sep 7, 2007

Hi, i'm trying to do a full text search on my site to add a weighting score to my results.  I have the following database structure:
Documents: - DocumentID (int, PK) - Title (varchar) - Content (text) - CategoryID (int, FK)
Categories: - CategoryID (int, PK) - CategoryName (varchar)
I need to create a full text index which searches the Title, Content and CategoryName fields.  I figured since i needed to search the CategoryName field i would create an indexed view.  I tried to execute the following query:
CREATE VIEW vw_DocumentsWITH SCHEMABINDING ASSELECT dbo.Documents.DocumentID, dbo.Documents.Title, dbo.Documents.[Content], dbo.Documents.CategoryID, dbo.Categories.CategoryNameFROM dbo.Categories INNER JOIN dbo.Documents ON dbo.Categories.CategoryID = dbo.Documents.CategoryID
GOCREATE UNIQUE CLUSTERED INDEX vw_DocumentsIndexON vw_Documents(DocumentID)
But this gave me the error:
Cannot create index on view 'dbname.dbo.vw_Documents'. It contains text, ntext, image or xml columns.
I tried converting the Content to a varchar(max) within my view but it still didn't like.
Appreciate if someone can tell me how this can be done as surely what i'm trying to do is not ground breaking.

Why Would Tables Pulled In From ODBC In Access Be Different Than Tables In SQL 2005 Tables?

Jan 24, 2008

I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.

I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!

So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?

Thanks,
Keith

Track The Changes To Normalised Tables And Update The Denormalised Tables Depending On The Changes To Normalised Tables

Dec 7, 2006

We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process

Can I Export Tables So That Existing Tables In Destination Database Will Be Modified?

Jul 20, 2005

I'm working on an ASP.Net project where I want to test code on a localmachine using a local database as a back-end, and then export it tothe production machine where it uses the hosting provider's SQL Serverdatabase on the back-end. Is there a way to export tables from oneSQL Server database to another in such a way that if a table alreadyexists in the destination database, it will be updated to reflect thechanges to the local table, without existing data in the destinationtable being lost? e.g. suppose I change some tables in my localdatabase by adding new fields. Can I "export" these changes to thedestination database so that the new fields will be added to thedestination tables (and filled in with default values), without losingdata in the destination tables?If I run the DTS Import/Export Wizard that comes with SQL Server andchoose "Copy table(s) and view(s) from the source database" and choosethe tables I want to copy, there is apparently no option *not* to copythe data, and since I don't want to copy the data, that choice doesn'twork. If instead of "Copy table(s) and view(s) from the sourcedatabase", I choose "Copy objects and data between SQL Serverdatabases", then on the following options I can uncheck the "CopyData" box to prevent data being copied. But for the "CreateDestination Objects" choices, I have to uncheck "Drop destinationobjects first" since I don't want to lose the existing data. But whenI uncheck that and try to do the copy, I get collisions between theproperties of the local table and the existing destination table,e.g.:"Table 'wbuser' already has a primary key defined on it."Is there no way to do what I want using the DTS Import/Export Wizard?Can it be done some other way?-Bennett

Saving Tables That Are Generated By Queries As HTML File Or Sub-tables

Oct 17, 2006

I have a trade data tables (about 10) and I need to retrieve information based on input parameters. Each table has about 3-4 million rows.

The table has columns like Commodity, Unit, Quantity, Value, Month, Country

A typical query I use to select data is "Select top 10 commodity , sum(value), sum(quantity) , column4, column5, column6 from table where month=xx and country=xxxx"

The column4 = (column2)/(total sum of value) and column 5=(column3)/(total sum of quantity). Column6=column5/column4.

It takes about 3-4 minutes for the query to complete and its a lot of time specially since I need to pull this information from a webpage.

I wanted to know if there is an alternate way to pull the data from server ?

I mean can I write a script that creates tables for all the input combinations i.e month x country (12x228) and save them in table (subtable-table) with a naming convention so from the web I can just pull the table with input parameters mapped to name convention and not running any runtime queries on database ??

OR

Can I write a script that creates a html files for each table for all input combinations save them ?

OR

Is there exists any other solution ?

Insert Records From Foxpro Tables To SQL Server Tables

Apr 22, 2004

Hi,

Currently, I'm using the following steps to migrate millions of records from Foxpro tables to SQL Server tables:

1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables in a dummy database. All the SQL tables have the same columns as the Foxpro tables.
2. Manipulate the data in the SQL tables of the dummy database and save the manipulated data into the SQL tables of the real database where the tables may have different structure from the corresponding Foxpro tables.

I only know the following ways to import Foxpro data into SQL Server:

#1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables
#2. Transfer Foxpro records to .dat files and then Bulk Insert to SQL Server tables
#3. DTS Foxpro records directly to SQL Server tables

I'm thinking whether the following choices will be better than the current way:

1st choice: Change step 1 to use #2 instead of #1
2nd choice: Change step 1 to use #3 instead of #1
3rd choice: Use #3 plus manipulating in DTS to replace step 1 and step 2

Thank you for any suggestion.

Temp. Tables / Variables / Process Keyed Tables ?

Feb 22, 2008

I have 3 Checkbox list panels that query the DB for the items. Panel nº 2 and 3 need to know selection on panel nº 1. Panels have multiple item selection. Multiple users may use this at the same time and I wanted to have a full separation between the application and the DB. The ASP.net application always uses Stored Procedures to access the DB. Whats the best course of action? Using a permanent 'temp' table on the SQL server? Accomplish everything on the client side?

Basic, and even medium sized (10,000+ records) reportingrun at an acceptable speed, but for anything larger, IIS timeouts andquery timeouts often cause problems.I subsequently came up with the idea that I could reduce processingtimes by up to two-thirds by writing information from eachcalculationstage to a number of tables as the reporting procedure runs..ie. stage 1, write to table xxx1,stage 2 reads table xxx1 and writes to table xxx2,stage 3 reads table xxx2 and writes to table xxx3,etc, etc, etcprocedure read final table, and outputs information.This works wonderfully, EXCEPT that two people can't run the samereport at the same time, because as one procedure creates and writesto table xxx2, the other procedure tries to drop the table, or read atable that has already been dropped....Does anyone have any suggestions about how to get around thisproblem?I have thought about generating the table names dynamically using'sp_execute', but the statement I need to run is far too long(apparently there is a maximum length you can pass to it), and evenbreaking it down into sub-procedures is soooooooooooooooo timeconsuming and inefficient having to format statements as strings(replacing quotes and so on)How can I use multiple tables, or indeed process HUGE procedures,withdynamic table names, or temporary tables?All answers/suggestions/questions gratefully received.Thanks

How To Create Multiple Tables On The Fly So That Every User Each Has His/her Own Set Of Tables?

Aug 12, 2006

Hello all,

Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.

Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.

What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1

Please help :-D

Greetingz,

DJ Roelfsema

Adding Sql Parameter In VB

Oct 16, 2006

I have a details view with several parameters set up in my asp.net 2.0 code, I want to add a parameter before the sql parameter is executed. I need to use the find control of the details view because I am using items/edit item templates in my details view control. I tried this(see below) as well as the detailsview item command event args to no avail. It doesn't see the other parameters that have already been declared in my asp.net code. I don't want to have to declare all my varibles that are already in my asp.net code. I just want to add another parameter.  Sub InsertNew(ByVal sender As Object, ByVal e As DetailsViewInsertEventArgs) _    Handles dvEvents.ItemInserting        Dim dvr As DetailsViewRow        For Each dvr In dvEvents.Rows  Dim CatIDup As Integer = CType(dvr.FindControl("ddlCat"), DropDownList).SelectedValue            sdsevents.InsertParameters.Add("evCatID", CatIDup)sdsevents.Insert()

Adding An Image To SQL

Dec 4, 2006

Looking for any help someone can offer on adding an image to SQL.Working on what will hopefully be quite a big site and the user will be asked for some details, one of which will be an image (jpg, gif or bmp).Rather than add the image to a folder on the server, a folder which could end up being quite large, I was hoping someone could give me some help, suggestions or even point me towards a tutorial on how to store the image in an SQL database.Any helps appreciated, thanks :)
