Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
Aug 29, 2006I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Jul 29, 2015In the following t-sql 2012 merge statement, the insert statement works but the update statement does not work. I know that is true since I looked at the results of the update statement:

This works great it gets the rows that i want except for there are 4 rows in which the FieldName value is Null and these are also being excluded. Can someone tell me why?
I have tried multiple variations on this select statement and either it doesn't exclude these rows or it excludes these and the nulls.

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement
Jan 9, 2015Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
SQL Server 2012 :: Update Statement With CASE Statement?
Aug 13, 2014i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename]
SET [No] =
CASE
WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa'
ELSE 'Null'
END
What is the best way to script this

Can’t Get SQL Statement To Work
Feb 15, 2006I’m using VB.NET to extract data from an Access database, simple enough. However, I type in the following line:
Sql = "SELECT * FROM [IPAddressList] WHERE [StartIPNo]>=" & IP_Address And "[EndIPNo]<=" & IP_Address
It doesn’t work.
If I type in:
Sql = "SELECT * FROM [IPAddressList] WHERE [StartIPNo]>=" & IP_Address
The above sql line works.
I now realize SQL commands is very sensitive.
FIELD NAMES:
quote:StartIP |EndIP|StartIPNo|EndIPNo|CountryCode
5.0.0.0 |5.163.66.79|83886080|94585423|ZA
5.163.66.80|5.163.66.95|94585424|94585439|SE
5.163.66.96|5.255.255.255|94585440|100663295|ZA
If the user types in a value, I want it to check the values between the StartIPNo and EndIPNo and return the CountryCode.
Any help would be appreciated

Stored Procedure - Update Statement Does Not Seem To Update Straight Away
Jul 30, 2007Hello,
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?
Go Not Work Within A Line String Of Sql Statement?...
Jul 14, 2003Hi:
the following is my TSQL command of a job(after passing databaseName, I don't want multiple steps, just with 1 step)
--===================================
BACKUP DATABASE ABC To Backup_ABC_1 with init, name = 'Backup of 1(M, W, F ) Job_ABC_1Mon' go backup log ABC with truncate_only go print 'shrinkdatabase begin-- ' dbcc checkdb(ABC) go dbcc shrinkdatabase(ABC, 10)
Issue: with 3 'go' inside the whole line, execution failed. after replace 'go' with 'begin' and 'end' for each sql statemet, the execution works. Someone could explain why 'go' as a batch does not work in this situation?
also, is this a good practice to
1. truncate_only
2. dbcc checkdb
3. shrinkdatabase
after a daily backup?
thanks

Rocket Science? How's This Statement Work?
Jan 18, 2006If any of you can tell me how the following SQL SELECT statement works , I will be forever grateful! What I mean is, if anyone has actually seen an SQL statement like this and knows what it does, I would be eternally grateful, because I have been writing SQL for over 10 years, and not only do I have no clue how this monstrosity works (and I assure you that it does work), I have never seen anything quite like it. The primary purpose of the code is to sort the chapel messages (mp3s) for my institutions website, but it moonlights for NASA as any code they deem necessary to perform the most complicated computerized tasks known to mankind.

UNION Statement Doesn't Work

Make sure it existsand that its name is spelled correctly."I can run the queries separately "SELECT field1 FROM table1" and "SELECTfield1 FROM table2", so that I'm sure table and field names are correctand I have permission to access them.Both field1 and field2 are the same type (int).If I run the query in MS SQL Query Analyzer, it works fine.It doesn't work only when I run it from VB/JET/ODBC.Has anyone already had this kind of problem?Any help will be highly appreciated!Thank you so much for the attention.--Posted via http://dbforums.com

As you can see it should return castedValue as integer but it cast to datetime which is wrong. If I commented line
Code Block
when me.ElementTypeId =4 then cast(mev.ElementValue as datetime)
it casts everything normal, but as soon as it has more than one condition in CASE it will choose anything but not right casting
Looks like I am missing something really fundamental. Any help is apreciated !

Can't Make This Update Work - Advice??
Feb 26, 2008Hi - I'm in a situation with a very large table, and trying to run an update that, any way I've approached it so far, seems to be taking unnacceptably long to run. Table has about 20 million rows, looks something like this:
ID - int, identity
Type - varchar(50)
PurchaseNumber - varchar(50)
SalesAmount - Money
ID Type PurchaseNumber SalesAmount
1 A 3834AA38384 20.32$
2 B 3834AA38384 11837.32$
3 C 3834AA38384 666.32$
4 C 887DF88U01H 23423.32$
5 A 887DF88U01H 12.32$
6 B OI83999FH28 4747.1$
7 D 38438495985 9384.6
8 E 02939DDJJWI 22.22$
9 F 07939SDFDF2 33.33$
The goal of the update is to make the [Type] uniform across [PurchaseNumbers], according to the max sales amount. For each PurchaseNumber a, set the type = the type of the row that has the MAX salesAmount. If there is only one entry for PurchaseNumber, leave the type alone. Expected update after completion would look like this:
ID Type PurchaseNumber SalesAmount
1 B 3834AA38384 20.32$
2 B 3834AA38384 11837.32$
3 B 3834AA38384 666.32$
4 C 887DF88U01H 23423.32$
5 C 887DF88U01H 12.32$
6 B OI83999FH28 4747.1$
7 D 38438495985 9384.6
8 E 02939DDJJWI 22.22$
9 F 07939SDFDF2 33.33$
I got this out of a warehouse, and it definitely isn't normalized well. Was considering breaking down into a better model, but I'm not yet sure if that would make the update easier.
I've been approaching this with sub-queries (finding all the PurchaseNumbers with more then one entry, then the max sales purchase of that purchase Number, then the type of that purchase number and sales amount to update all of that purchase number) but this not only ends up a little messy, but also very slow.
The only other detail that may be important is that out of the 20 million total rows, about 19.5 million purchaseNumbers are unique. So, really, there are only about 500k rows I actually have to update.
I've thought of a few ways to make this work, but none of them seem fast and wanted to see if anyone had a pointer. Thanks!
Easy One(?) Converting Sql05 Statement To Work In Sql Express
Feb 7, 2008
Hi, I was handed an old application written for sql05, it has this (kind of) statement:
Dim CommandText As String = "SELECT c.name FROM db1 c LEFT JOIN "
CommandText += "db2.dbo.Users u ON u.iKey = c.key "
CommandText += "WHERE u.cUserName = '" & User & "'"
As you can see, there are two databases, db1 and db2 and this worked fine in sql05, but when I convert each of the databases to sqlexpress, I get this error: Invalid object name 'db2.dbo.Users'.
So how can I make this work in sqlexpress? Are queries across databases not allowed?
Thanks so much for your help!
SqlDataSource Update Doesn't Work When Using Parameter
Feb 3, 2007Hi all:
I have a list of items (actually a relation in which a user has selected an item, along with a rating for the item) in an Access database table, connected to my app with a SqlDataSource and bound to a repeater. The repeater displays the items to the user along with a dropdown box to show the rating, and allow the user to update it. The page connects and displays correctly.
My problem is that when the user submits the page and I iterate through the repeater items to update each rating, the updates are not being completed in the database. The update works if I hard-code a value for the rating into the query itself, but not when using an updateparameter (pTaskRating below). In other words if I replace pTaskRating with '5', all the correct records will be found and have their ratings updated to 5. That means that the mySurveyId and pTaskId(DefaultValue) parameters have to be working, because the right records are found, but I can't seem to update records based on the DefaultValue of the pTaskRating parameter, even though I can verify that the DefaultValue is correct by placing a watch on it. It seems that my problem must be in my use of that particular parameter in the query, either in properties of the parameter or in the value assigned to it. I am extremely frustrated - any ideas would be greatly, greatly appreciated. Thanks!

SURVEY_ID (Text 50), TASK_ID (Long Int), RATING_ID (Long Int)
Here's my ASPX for the main data source:
<asp:SqlDataSource ID="sqlTaskSelections" runat="server" ConnectionString='Provider=Microsoft.Jet.OLEDB.4.0;Data Source="abc.mdb";Persist Security Info=True;Jet OLEDB:Database Password=xyz' ProviderName="System.Data.OleDb" SelectCommand="SELECT [SURVEY_ID], [TASK_ID], [RATING_ID] FROM [TBL_TASK_SELECTION] WHERE [SURVEY_ID] = mySurveyId" UpdateCommand="UPDATE [TBL_TASK_SELECTION] SET [RATING_ID] = pTaskRating WHERE ([SURVEY_ID] = mySurveyId) AND ([TASK_ID] = pTaskId)">
<UpdateParameters>
<asp:SessionParameter Name="mySurveyId" SessionField="SurveyId" DefaultValue="" /><asp:Parameter Name="pTaskId" DefaultValue="" /><asp:Parameter Name="pTaskRating" DefaultValue="" />
</UpdateParameters>
And here's the repeater (the Task ID and Rating are stored in hidden fields for easy access later):
<asp:Repeater ID="rptTaskSelections" runat="server">
<HeaderTemplate><table border="0"></HeaderTemplate>
<ItemTemplate>
<tr class="abctr"><td class="normal"><asp:DropDownList ID="cbRatings" runat="server"></asp:DropDownList><asp:HiddenField ID="hTaskId" Runat="server" Visible="false" Value='<%# Eval("TASK_ID") %>' /><asp:HiddenField ID="hRating" Runat="server" Visible="false" Value='<%# Eval("RATING_ID") %>' /> <%# Eval("TASK_ID") %></td></tr>
</ItemTemplate>
<FooterTemplate></td></tr></table></FooterTemplate>
</asp:Repeater>
And here's the page load and submit VB:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
'BIND / LOAD RATINGS TO DROPDOWN BOXES HEREDim i As IntegerDim cbCurrentRating As DropDownListDim hCurrentRating As HiddenFieldrptTaskSelections.DataSource = sqlTaskSelectionsrptTaskSelections.DataBind()
For i = 0 To rptTaskSelections.Items.Count - 1
cbCurrentRating = rptTaskSelections.Items(i).FindControl("cbRatings")hCurrentRating = rptTaskSelections.Items(i).FindControl("hRating")
cbCurrentRating.DataSource = sqlRatingscbCurrentRating.DataTextField = "RATING"cbCurrentRating.DataValueField = "ID"cbCurrentRating.DataBind()cbCurrentRating.SelectedValue = hCurrentRating.Value
Next
End If
End Sub
Protected Sub btnSubmitRateTasks_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmitRateTasks.Click
'UPDATE RATINGS HERE
Dim i As IntegerDim cbCurrentRating As DropDownListDim hCurrentTaskId As HiddenField
For i = 0 To rptTaskSelections.Items.Count - 1
cbCurrentRating = rptTaskSelections.Items(i).FindControl("cbRatings")hCurrentTaskId = rptTaskSelections.Items(i).FindControl("hTaskId")
sqlTaskSelections.UpdateParameters.Item("pTaskId").DefaultValue = hCurrentTaskId.ValuesqlTaskSelections.UpdateParameters.Item("pTaskRating").DefaultValue = cbCurrentRating.SelectedValue
sqlTaskSelections.Update()
Next
Response.Redirect("nextpage.aspx")
End Sub
Need Help Trying To Work With Forms Control To Update, Insert, And Etc...
Aug 14, 2007Hello,
I am trying to use the forms view control to do a simple web app. My issue is, I cant get the connection to automatically generate insert, update and delete statements. I tried to do this manually but I always get an error. I have read that I need all the keys selected--this still didnt work. I have about 6 tables picked in my view, and if I pick one of them then this advanced feature works. I have the primary keys selected.
here is my saved view. this is in SQL 2000.
SELECT TOP 100 PERCENT dbo.ADDRESS.EMAIL, dbo.ADDRESS.FIRST_NAME AS [first name], dbo.ADDRESS.LAST_NAME AS [last name], dbo.ADDRESS.STATE, dbo.ADDRESS.TEL1 AS phone, dbo.INVOICES.QUOTE_NO AS [SALES QUOTE], dbo.CUST.NAME AS Company, dbo.ITEMS.ITEMNO AS [Course Number], dbo.ITEMS.DESCRIPT AS S_Descript, dbo.ADDRESS.JOB_TITLE AS [Job Title], dbo.TRAINING_SCHEDULE.[MONTH], dbo.TRAINING_SCHEDULE.S_DATE, dbo.TRAINING_SCHEDULE.END_DATE, dbo.TRAINING_SCHEDULE.IS_CONFIRMED, dbo.TRAINING_SCHEDULE.IS_PAID, dbo.TRAINING_SCHEDULE.CUST_CODE AS Account, dbo.TRAINING_SCHEDULE.SCHEDULE_ID, dbo.CUST.CUST_CODE, dbo.INVOICES.INVOICES_ID, dbo.X_INVOIC.X_INVOICE_ID, dbo.ADDRESS.ADDR_CODEFROM dbo.TRAINING_SCHEDULE INNER JOIN dbo.CUST ON dbo.TRAINING_SCHEDULE.CUST_CODE = dbo.CUST.CUST_CODE RIGHT OUTER JOIN dbo.X_INVOIC RIGHT OUTER JOIN dbo.INVOICES ON dbo.X_INVOIC.ORDER_NO = dbo.INVOICES.DOC_NO LEFT OUTER JOIN dbo.ADDRESS ON dbo.INVOICES.CUST_CODE = dbo.ADDRESS.CUST_CODE LEFT OUTER JOIN dbo.ITEMS ON dbo.ITEMS.ITEMNO = dbo.X_INVOIC.ITEM_CODE ON dbo.CUST.CUST_CODE = dbo.ADDRESS.CUST_CODEWHERE (dbo.X_INVOIC.ITEM_CODE LIKE 'FOT-%') AND (dbo.X_INVOIC.STATUS = 7) AND (dbo.ADDRESS.TYPE IN (4, 5, 6)) AND (dbo.ADDRESS.EMAIL <> '') AND (dbo.ADDRESS.COUNTRY = 'UNITED STATES') AND (dbo.ITEMS.CATEGORY = 'TRAININGCLASSES') AND (dbo.TRAINING_SCHEDULE.CUST_CODE = 'joe')ORDER BY dbo.ADDRESS.STATE
I am new to this so I am not sure what to include.
thanks,

Trying To Work Out Why My Code Wont Update Or Write To The DB
Jan 7, 2008hi there, i have been wrestling with this for quite a while, as in my other post http://forums.asp.net/t/1194975.aspx, what someone advised me was to put in try catch blocks ot see whats going on, problem is i have never really done it whit this kinda thing before, and i was wondering if someone could point me in the right direction.
For example where would i put the try catch block in here, to show me if its not working public int getLocationID(int ProductID, int StockLoc)
{
// Gets the LocationID (Shelf ID?) for the stock column and product id
// passed
// The SQL will look Something like: string strSQL;
strSQL = "SELECT " + " location" + StockLoc + " " + "FROM " + " tbl_stock_part_multi_location " + "WHERE " + " stock_id = " + ProductID;string sConnectionString = "Data Source=xxxxx;Initial Catalog=xxxx;User ID=xxxx;Password=xxxxx";
SqlConnection objConnGetLocationID = new SqlConnection(sConnectionString);SqlCommand sqlCmdGetLocationID = new SqlCommand(strSQL, objConnGetLocationID);
objConnGetLocationID.Open();int intLocation = Convert.ToInt32(sqlCmdGetLocationID.ExecuteScalar());
return intLocation;
}
Update NULL Values Doesn't Work
Oct 2, 2007Hello everybody,
I can't perform an operation apparently very easy: set a field to a NULL value.
This is the db:
Microsoft SQL Server 2000 - 8.00.760 (Intel X86)
Dec 17 2002 14:22:05
Copyright (c) 1988-2003 Microsoft Corporation
Standard Edition on Windows NT 4.0 (Build 1381: Service Pack 6)
This is the table:
CREATE TABLE [ProgettoTracce] (
[ID_Progetto] [int] NOT NULL ,
[MisDifDef] [real] NULL ,
[MisDifMeas] [real] NULL ,
[MisDifAna] [real] NULL ,
[MisDifID] [real] NULL ,
[MisDifCV] [real] NULL
) ON [PRIMARY]
GO
This is qry:
UPDATE ProgettoTracce
SET MisDifDef = NULL
WHERE ID_Progetto = 3444
The qry has been performed with no error. Then I execute SELECT * FROM ProgettoTracce WHERE ID_Progetto = 3444 and I find the value I tried to overwrite with NULL. If I update with 0 (for example) it works.
Obviously this happens on the production db, because on the development db the update with NULL works fine.
No transaction is called, db options are the same on dbs...
What's happen? Have I to call an exorcist???
Thanks in advance for any help!

Help: Why IN-Operator With Select-Statement It Doesn't Work? But With Given Values It Works
Jun 4, 2007Hello to all,
i have a problem with IN-Operator. I cann't resolve it. I hope that somebody can help me.
I have a IN_Operator sql query like this, this sql query can work. it means that i can get a result 3418:
declare @IDM int;
declare @IDO varchar(8000);
set @IDM = 3418;
set @IDO = '3430'
select *
from wtcomValidRelationships as A
where (A.IDMember = @IDM) and ( @IDO in (3428 , 3430 , 3436 , 3452 , 3460 , 3472 , 3437 , 3422 , 3468 , 3470 , 3451 , 3623 , 3475 , 3595 , 3709 , 3723 , 3594 , 3864 , 3453 , 4080 ))
but these numbers (3428 , 3430 , 3436 , 3452 , 3460 , 3472 , 3437 , 3422 , 3468 , 3470 , 3451 , 3623 , 3475 , 3595 , 3709 , 3723 , 3594 , 3864 , 3453 , 4080 ) come from a select-statement. so if i use select-statement in this query, i get nothing back. this query like this one:select *
from wtcomValidRelationships as A
where (A.IDMember = @IDM) and ( @IDO in (select B.RelationshipIDs from wtcomValidRelationships as B where B.IDMember = @IDM))
I have checked that man can use IN-Operator with select-statement. I don't know why it doesn't work with me. Could somebody help me? Thanks
I use MS SQL 2005 Server Management Stadio Express
Thanks a million and Best regards
