SQL Server :: Updating The Tables From Another Table?
Jan 12, 2011
I have two tables master and comp table. In master table, I have columns called LB1, LB2, LB1_ID, LB2_ID and in my comp table I have ID and CompName. I need to update my master table the following way
If LB1 in master table has a value of 'XYZ' then I need to find that value in Comp Table in column compName and then put the ID from comp table to master table in LB1
master
LB1 LB2 LB1_ID LB2_ID
XYZ HIJ
ABC KLM
DEF RAW
PQR VQS
Comp
ID CompName
1 XYZ
2 ABC
3 RAW
4 DEF
5 VQS

I need to poulate my master table like this
master
LB1 LB2 LB1_ID LB2_ID
XYZ HIJ 1 6

I have an excel sheet with 2 tabs and has data in those 2 sheets(sheet1, sheet2) which correspond to different tables in the same database. This excel sheet gets updated daily, I am wiriting a console app( which will later be a batch build). I have to insert the data from the excel sheet to corresponding tables (table1, table2,table3) in database when i run it and and also if the table has the same data already present it should ignore and if there are any modifications done the data it should update the table. I know we can do this using ado.net or LINQ, I am a little new to database based programming .
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.
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.
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.
[Code]....
I don't understand why it is not updating into the table. Especially since I am getting no errors.
Inner Join:- Returns a row when there is matching table in both tables. we can use comparison operator like =,<,>,<>
I created two tables
TableA
ID OID Type
1 1 A 2 6 B 3 7 C 4 10 D
TableB
ID Value 1 10 2 30 3 40 5 60 6 70
Basic Inner Join select Type From TableB as a inner join TableA as b on a.ID=b.OID Result Type
A B
If i want only the type which has not match in tableB then i can use not in subquery i get the result if i m using select Type From TableB as a inner join TableA as b on a.ID<>b.OID then i get
I have a simple sql that selects records from some tables and insert them in one other table.This is what we need to do on a daily basis and we need to create a sql job for this.
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.
I m getting following error in my eventvwr . I couldnt find reasons of the following error.
"Transaction (Process ID 110) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. "
The only thing my page is doing is inserting/updating data into a table in sql and the thing I can think of is because multiple users are using the same page to insert/update data? Will that cause deadlock?
I have a web application and on page is an update page to update some profile information. Below is the code I am using to update the table. But I think it is wrong. Does anything stick out? The connection string works cause it is used to read the database to get the profile information, I just removed it due to it containing password/login info for the db.player is the class of properties that contains player information and ds is the dataset, but I would like to update the database itself online...
Dim connectionString As String = "" Dim GigsterDBConnection As New System.Data.SqlClient.SqlConnection(connectionString) GigsterDBConnection.Open()[code]....
I think the issue is something the 3 last lines of the code. am I doing it right or is their a better way?
In the following code, the user documents types are not getting updated, they do initially but don't stay updated. perhaps you can see something blatant here:
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:
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:
[code]...
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?
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??
I am using bulk insert concept to export the data from dat file to tables(Two tables). I am using the temporary table for to do the calculation and insertion to two tables. My problem is whenever I selecting the temp table data after the execution of bulk insertion , the order is changing .I need to get the order as it is in file order(csv,dat,txt).
I'm trying to update a row in a table in our sqlserver database i created (first time).I am getting this error, and what follows is the code. ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized.
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. I am using exactly the same code (with different parameters, obviously) to update another table and this continues to work fine.

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 Try 'I have created a session variable for my data adapter Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter")) Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand Session("Adapter").DeleteCommand = commandbuilder.GetDeleteCommand 'I created a session variable for my dataset 'This update command updates new rows to my database table but not deleted rows Session("Adapter").Update(Session("CalendarDataset"), "Name") Catch ex As Exception Response.Write(ex.Message) End Try End Sub
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?
[Code]....
And, strangely enough, the same code doesn't work with parameters. How is that?:
