SQL Server :: Updating Multiple Tables Simultaneously

Sep 8, 2010

Was wondering if someone can help me out with this multi update problem

I have a webform that populates a single table but due to certain dropdown data conditions it could also potentially populate 3 other tables

The tables information populates a gridview with amounts from accounts etc..


Table 1

Site DataType account update

34 SS 12.50 N

Table 2

Site account

34 12.50

Say the above entry has the updated column changed to Y via the webform the amount 12.50 should disappear from the gridview. I was

a bit shortsighted and added the additional tables afterward. The information on the gridview pulls from the additional tables and since

the first table and the additional tables are not linked the data still stays the same in the gridview

I do have an Id column on both tables but unfortunately I added the rest of the tables after the first one so the Id's do not really match.

Databases :: Importing - Updating Sql Tables From Excel Sheet Into Multiple Tables Daily

Jan 4, 2011

I have an C# ASP application I am writing that needs to have the capability to import a generated excel or a comma delineated sheet each day. A clerk will have this job each morning so it doesn't need to be automated. My problem in trying to understand the solution to this is that the 1 sheet contains loan information, including customer information all in the same sheet. I would like to send certain columns to update information in the loan table and send other information to update the customer table. I need it to create relationships when new loans appear in the spreadsheet.

SQL Server :: Merging Three Tables Together In One Table?

Jan 7, 2011

I have three tables. I need to merge these three tables into one table. There is an ID column in all these three tables. The ID's can be same in all three tables or they can be different. If the IDs are same then I need to merge based on those ID's so if the ID 1 exists in Table A, table B and Table C then one row will be created in the resulting master tables, but if the Id's are different then one individual row will be created in each table.

Also, some of the columns are same in all three tables, but some are different, but if the ID is same then I just want to append that column in the existing table.

SQL Server :: Updating One Table Pulled From Another?

Mar 2, 2011

I am trying to track members volunteering. I have a table that has all our members information and another table I want to update what they volunteer for throughout the year. I have a ddl that they select a last name and it populates first name, last name and spouse in a formview. This all works. There are a couple of other textboxes that need to be filled out. When I try and run an update into the volunteer table I get no errors and page shows the meber was updated. However, when I go into the volunteer table, there is no data.


I don't understand why it is not updating into the table. Especially since I am getting no errors.

SQL Server :: Insert Data From 2 Tables Into The 3rd Table?

Mar 18, 2011

I have 3 tables. I need to insert data from 2 tables into the 3rd table.

The first table has 2 fields -- c_id, c_key

The second table has -- t_id, u_id, partial_c_key

I need to insert c_id, u_id in the 3rd table.

Problem is partial_c_key in the second table contains only a part of the c_key in the first table.


First table:


Second Table:

t_id -- u_id -- partial_c_key

In the data above partial_c_key 200 has 3 c_ids in the first table (1,2,3 with values 200A, 200B, 200C) and 301 has just 1 which is 301A.

In the 3rd table I need to insert c_id, u_id so the data should be

u_id -- c_id
23 -- 1
23 -- 2
23 -- 3
36 -- 4

How do I write a query to accomplish that?

SQL Server :: Database Design / Create A Separate Table Which Will Contain The Translations For All 50 Tables?

Sep 28, 2010

I am working on a multi-lingual application Assume the following:

Database has 50 tables and application has to support 5 languages

Which is the best way to design the database:

1. Include a langugae column for each table. Repeat the values for each language. Say i have a country table which has 100 countries in it. Then my design will contain 500 rows (100 for each langugae)

2. Create a separate table which will contain the translations for all the 50 tables in with a foreign key to the parent table.

Which is more efficient out of the above two.

MVC :: Check Boxes Not Updating Membership Or Roles Tables?

Feb 8, 2010

I've got an MVC 1.0 View that is more-or-less an attempt at reproducing WSAT.

On the Security->Manage Users page there's a column of checkboxes for "Active" for each user. Also when clicking the 'Edit roles' link a set of roles shows up in the Roles column of the table.

I'm using the standard SQL based Membership and Role providers that come out of the ASP.NET box.

For some reason, when I run the app from VS2008 all is well and I can update the Active and Roles values. However, when I deploy to a remote server, either my test server or in production, the checkboxes don't update the databse. Note that the links for 'Edit user', 'Delete user' work fine. I can create a new user or delete a user with no problems in any of the deployed locations. Also the 'Edit roles' link also works fine in that it brings up the list of all possible roles and shows which roles the user is in. The problem is specifically with the Checkboxes.

Interesting to note is that the JavaScript alert() (see below) does fire when clicking on any of the Role checkboxes. However, although the box is checked, the database is not updated on the any but VS2008 Casini. The database connection string is not changed on any of the execution sites which are running SQL 2008. IIS 7 on one deployed server (an ISP) and 7.5 on the other my in-house test server.

Here's the code I'm using to create the Roles portion of the page:

C# - Best Practice For Inserting/updating Data In Multiple Tables At Once?

Feb 11, 2011

So I have two tables in my database, Contacts and Addresses:

Contacts : ContactID | AddressID | FirstName | LastName

Addresses: AddressID | Address1 | Address2 | City | State | Zipcode

I have a page where you can add a contact. It contains all the information for a contact and an address for a contact. Here's my code for when you submit the form:


Now my main concern is that the address is added successfully, but then an error occurs when I try to save the contact, leaving the address in the database with no contact.

What's the best practice here for rolling back any changes if an error occurs?

DataSource Controls :: Adding Rows And Updating Tables From Datatable

Mar 7, 2010

Maybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.

The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work

So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.

Please helpe with this.

PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??

VS 2008 Updating Table Fails

why this update is failing? The table is connected to OK and there are appropriate values in the parameters to the subroutine, and yet the record in the table remains unchanged.

Feb 22, 2011

I have an asp.net application using visual studio express 2008. On one of my pages I created a dataset from one of my database tables. I am able to delete rows and add rows to the new dataset table. I then have a button and on the click event I use the commandbuilder to update the database table. The database table updates with new rows but the deleted rows are not carried out and I can not figure out why desite spending several hours on google to resolve this issue?

Here is some of my code:

Protected Sub Button_updateDatabase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_updateDatabase.Click
'I have created a session variable for my data adapter
Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter"))
Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand

'I created a session variable for my dataset
'This update command updates new rows to my database table but not deleted rows

ADO.NET :: Convert String To Int Before Updating Database Table?

I have a form in which I display data from a database table, change the data and then update the database table. The form consists of textboxes, so all data displayed in the form is string. However - one data is int in the database table (the rest is varchar), so I need to convert it from string to int when I update the database table. How do I do it?


And, strangely enough, the same code doesn't work with parameters. How is that?:
