Update Table In SQL Database

Nov 23, 2004

Hi,





I have a id field in sql database which is of data type varchar. I want to update multiple records in this table at once or in one query. Here is the code





sqlBuilder.Append("Update Students set EventDate='2004/12/24' ")


sqlBuilder.Append("Where ID IN (@StudIDs)")


cmdStudent= New SqlCommand


cmdStudent.Connection = connDB


cmdStudent.CommandType = CommandType.Text


cmdStudent.CommandText = sqlBuilder.ToString()


cmdStudent.Parameters.Add("@StudIDs", SqlDbType.VarChar, 1000).Value = strStudentIDs


cmdStudent.Prepare()


cmdStudent.ExecuteNonQuery()








The value of strStudentIDs is "A2227,B5629".





Its working fine if I am pasing only one id but its not updating the table if I am passing more that one IDs and I am not getting any error message. Then I tried to get it working by passing the strings with single quotes as:





The value of strStudentIDs is "'A2227','B5629'".





Still it did not work.





I got this to work by using Dynamic SQL but I want to do it with string builder instead.








How can I solve this problem?





Thanks!

Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table.

Using Textboxes And Dropdownboxes To Update Database Table

Apr 24, 2008

ASP 3.5 VB: Visual Studio 2008, 2005 Developer Server
I'm new to web development so my question may seem basic. I created a stored procedure:CREATE PROCEDURE [dbo].[CaseDataInsert]
@ReportType varchar(50),
@CreatedBy varchar(50),
@OpenDate smalldatetime,
@Territory varchar(10),
@Region varchar(10),
@StoreNumber varchar(10),
@StoreAddress varchar(200),
@TiplineID varchar(50),
@Status varchar(50),
@CaseType varchar(200),
@Offense varchar(200)
 
AS
BEGININSERT CaseData(ReportType, CreatedBy,OpenDate,Territory,Region,StoreNumber,StoreAddress,TiplineID,
Status,CaseType,Offense)
VALUES(@ReportType,@CreatedBy,@OpenDate,@Territory,@Region,@StoreNumber,@StoreAddress,@TiplineID,
@Status,@CaseType,@Offense)
END
 
I created textboxes and dropdownboxes on my asp page, and with a button put the following code behind it:Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim cs As String = "Data Source=localhost;Initial Catalog=Database1.mdf;Integrated Security=True;"Using con As New System.Data.SqlClient.SqlConnection(cs)
con.Open()Dim cmd As New System.Data.SqlClient.SqlCommand
cmd.Connection = con
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = "CaseDataInsert"cmd.Parameters.AddWithValue("@ReportType", DropDownList1.SelectedItem)
cmd.Parameters.AddWithValue("@CreatedBy", DropDownList2.SelectedItem)cmd.Parameters.AddWithValue("@OpenDate", TextBox1.Text)
cmd.Parameters.AddWithValue("@Territory", TextBox2.Text)cmd.Parameters.AddWithValue("@Region", DropDownList3.SelectedItem)
cmd.Parameters.AddWithValue("@StoreNumber", TextBox3.Text)cmd.Parameters.AddWithValue("@StoreAddress", TextBox4.Text)
cmd.Parameters.AddWithValue("@TiplineID", TextBox5.Text)cmd.Parameters.AddWithValue("@Status", DropDownList4.SelectedItem)
cmd.Parameters.AddWithValue("@CaseType", DropDownList5.SelectedItem)cmd.Parameters.AddWithValue("@Offense", DropDownList6.SelectedItem)
End Using
End Sub
On the web page I can enter the data, click the button, and no data is entered into the database?
I believe that I may have problems with the datasource?
Any help would be appreciated.

Automatically Update Datetime Field In A Database Table.

Feb 28, 2006

hi e'body:

I have some database tables, and each one of them have a creation_date and modified_date in them. I was trying to figure out a way where when a row in one of these tables is changed using Enterprise Manager (Database -> Tables -> select table -> right click -> select all rows -> change a field in a row inside a table), is there a way apart from triggers, such that the "modified_date" column for that row get changed to 'getdate()' (rather picks up the current datetime).

thanks in advance.

Create A Custom Webpage To Edit/update A Table In A SQL Database.

Aug 25, 2007

Hi everyone, this is is my first post, so please reply and help.
I'm working on a project right now that uses asp 2.0 and SQL server 2005 express edition. This is a general idea of the project. In our company some of us receive ECO notifications (engineering change orders) for our products and we need to implement these to the test scripts that are on the production floor.  So the project is about entering the new ECO into a database which will send an automatic notification to our test team. When they receive the notification they will have to sign in to the website and introduce their login and password to sign off the ECO (Following some checkpoints already defined by me, for example, Area ready, Test script modification necessary, new firmware introduction, comments, etc...) but I also need to record WHO and WHEN sign that ECO. We have 3 different test areas in our factory: Electrical, Functional and Systems, so all THREE areas must be signed off in order to the ECO go to a IMPLEMENTED state (at this point i need to send a new email saying that the eco has been implemented in all three areas).
 So far I've completed the following things:
-users validation (logins, areas)
-New custom entry form for the ECOs and automatic email notification (part of what I did is described below). Dim ECODataSource As New SqlDataSource()ECODataSource.ConnectionString = ConfigurationManager.ConnectionStrings("ECO_ICSConnectionString1").ToString()
 
ECODataSource.InsertCommandType = SqlDataSourceCommandType.StoredProcedure
ECODataSource.InsertCommand = "EcoNew"
 ECODataSource.InsertParameters.Add("EcoNumber", EcoNumberTextBox.Text)
ECODataSource.InsertParameters.Add("EcoDescription", EcoDescriptionTextBox.Text)
ECODataSource.InsertParameters.Add("EcoMandatory", EcoMandatoryDropDownList.Text)
 -Depending on which test area is the the engineering from, I can filter the ECOs and just shows the ones that their test area is pending. (using GridView)
But I'm stuck right now when the engineers have to sign the ECO for their test areas. I was able to use the Gridview and DetailsView to EDIT most of the things that I need. But there are somethings that I don't like:
1. When using the EDIT option on Gridview or Detailsview, all fields can be edited including ECO number, description and mandatory, which I don't want them to change. If I set those columns to read only, when editing that row again. It gives me an error that says that the ECOnumber can't be  NULL, but if I remove these 3 columns the Engineer will not know which ECO they have sign. They are only going to be able to see the EcoId, which doesn't say much.
2. Also I saw that I wasn't able to do is to enter the USER login and CURRENT system date and time automatically. I don't want them to manually enter the date and their login manually.
3. Finally, when the last area signs the ECO, I want to update that record and set a flag that tells me that the ECO has been completed.
 So what I really want is to create some sort of form (textboxes, labels, checkboxes, etc.) that will UPDATE the selected ECO from the gridview for instance. So when I select the row from the GridView, It will show the data (Econumber, description and mandatory as READ ONLY) and use the rest of the things as INPUT for the engineer to complete. At the end an "update button" and when I click it, It will enter/update the data on that specific row, but including the time and user login as well.
Also to check if the other 2 areas have signed and if so, change the ECOReadiness flag to 1 and send the email.
Is there a code like the one I used above to do this ? Or if you think there a better way to do this, I'll be very glad to hear it.
 I'm new using sql and asp, so If i'm asking some dumb questions please forgive me. .
 
Here's my table definition for your reference:
EcoId - primary key.
EcoNumber
EcoDescription
EcoMandatory
EcoReadiness   <- Flag for the entire ECO, when ALL 3 areas have signed, this will be 1.
ATE < - Flag for Electrical area.
ATEscripts < - Just a Yes/no input.
ATEengineer <- user login
ATEdatetimestamp <- Date.Now()
FAT < - Flag for functional.
FATscripts
FATengineer
FATdatetimestamp
SYSTEMS < - Flag for systems.
SYSTEMSscripts
SYSTEMSengineer
SYSTEMSdatetimestamp
 
THANKS IN ADVANCE,
Regards,
Jesus

Problem With Update When Updating All Rows Of A Table Through Dataset And Saving Back To Database

Feb 24, 2006

Hi,
I have an application where I'm filling a dataset with values from a table. This table has no primary key. Then I iterate through each row of the dataset and I compute the value of one of the columns and then update that value in the dataset row. The problem I'm having is that when the database gets updated by the SqlDataAdapter.Update() method, the same value shows up under that column for all rows. I think my Update Command is not correct since I'm not specifying a where clause and hence it is using just the value lastly computed in the dataset to update the entire database. But I do not know how to specify  a where clause for an update statement when I'm actually updating every row in the dataset. Basically I do not have an update parameter since all rows are meant to be updated. Any suggestions?
SqlCommand snUpdate = conn.CreateCommand();
snUpdate.CommandType = CommandType.Text;
snUpdate.CommandText = "Update TestTable set shipdate = @shipdate";
snUpdate.Parameters.Add("@shipdate", SqlDbType.Char, 10, "shipdate");
string jdate ="";
for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
{
jdate = ds.Tables[0].Rows[i]["shipdate"].ToString();
ds.Tables[0].Rows[i]["shipdate"] = convertToNormalDate(jdate);
}
da.Update(ds, "Table1");
conn.Close();
 
-Thanks

How To Correctly Update A Table Which Values Can Be Either Inserted/updated/deleted On Update?

Feb 16, 2006

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

Transact SQL :: Firing After Update Trigger - On Table Row Update

Jul 8, 2015

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
 
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),

I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.

I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

Trying To Save Editted Textbox Value In Table But Original Value Saves Instead - Trouble With Table Update Query

Jan 9, 2008

This program gets the values of A and B passed in. They are for table columns DXID and CODE. The textbox GET1 is initialized to B when the page is loaded. When I type another value in GET1 and try to save it, the original initialized value gets saved and not the new value I just typed in. A literal value, like "222" saves but the new GET1.TEXT doesn't.

Stored Procedure That Fetch Each Row Of A Table And Update Rows In Another Table

Jan 31, 2006

I am working with the following two tables:

Category(NewID,OldID)
Link(CategoryID,BusinessID)

All fields are of Integer Type.

I need to write a stored procedure in sql 2000 which works as follows:

Select all the NewID and OldID from the Category Table
(SELECT NewID,OldID FROM Category)

Then for each rows fetched from last query, execute a update query in the Link table.

For Example,

Let @NID be the NewID for each rows and @OID be the OldID for each rows.
Then the query for each row should be..

UPDATE Link SET CategoryID=@CID WHERE CategoryID=@OID

Please help me with the code.

Thanks,

SQL Server 2012 :: Update Table From Variable Table Column?

Oct 6, 2014

I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.

This is my statement:

UPDATE [dbo].[sessions_teams] stc
SET stc.[Talks] = fmt.found_talks_type
FROM @Find_Missing_Talks fmt
WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks)
AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)
