hi, i have a simple question, it sounds a bit silly but i have not been able to figure it out. i want to be able to pass variable from code behind to an sqldatasource, i have been using session varibles, but is now becoming a bit messy as i have over 30 session viarables. i wanted to find out if i can create a private variable in the code behind, and access the value.
Does anyone know how i can do this, i'm not sure if it is possible, if it is what paramater i can use to access it.
Or if anyone has any better ideas to create variables for one page, so i can pass it to sqldatasource, would be great..
Hi all, I was wondering if anyone can help me figure out how to insert a variable into a query using Visual Studio 2005 with the SqlDataSource control. I cant seem to be able to enter a var into the query parameters.
this is my SqlDataSource: <asp: SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:imLookinLikeConnectionString %>" DeleteCommand="DELETE FROM [tblDiaryEntries] WHERE [DiaryEntryID] = @DiaryEntryID" SelectCommand="SELECT tblDiaryEntries.DiaryEntryID, tblDiaryEntries.EntryDate, tblDiaryEntries.Subject, tblDiaryEntries.DiaryEntry, aspnet_Users.UserName FROM tblDiaryEntries INNER JOIN aspnet_Users ON tblDiaryEntries.UserID = aspnet_Users.UserId WHERE UserName=@UserName ORDER BY tblDiaryEntries.EntryDate DESC" UpdateCommand="UPDATE [tblDiaryEntries] SET [DiaryEntry] = @DiaryEntry, [EntryDate] = @EntryDate, [Subject] = @Subject WHERE [DiaryEntryID] = @DiaryEntryID" InsertCommand="INSERT INTO tblDiaryEntries(UserID, EntryDate, Subject, DiaryEntry) VALUES (@UserId, GETDATE(), @Subject, @DiaryEntry)"> <DeleteParameters> <asp: Parameter Name="DiaryEntryID" Type="Int32" /> </DeleteParameters> <UpdateParameters> <asp: Parameter Name="DiaryEntry" Type="String" /> <asp: Parameter Name="EntryDate" Type="String" /> <asp: Parameter Name="Subject" Type="String" /> <asp: Parameter Name="DiaryEntryID" Type="Int32" /> </UpdateParameters> <InsertParameters> <asp: Parameter Name="DiaryEntry" Type="String" /> <asp: Parameter Name="EntryDate" Type="String" /> <asp: Parameter Name="Subject" Type="String" /> <asp: ProfileParameter DefaultValue="Anonymous" Name="UserName" PropertyName="UserName" /> <asp: Parameter Name="UserId" /> </InsertParameters> <SelectParameters> <asp: ProfileParameter DefaultValue="Anonymous" Name="UserName" PropertyName="UserName" /> </SelectParameters> </asp: SqlDataSource> What I want to do is to tell the SqlDataSource that @UserName = this.User.Identity.Name, but I only know how to do that in code-behind, not sure how to insert it into the code above.Any ideas?
UpdateCommand="UPDATE PsnQualifications SET quantity=@quantity WHERE rowstatus=1 and qualId=@original_qualId"
DeleteCommand="UPDATE PsnQualifications SET rowStatus=0, lastUpdateOn=getdate(), lastUpdateBy=@createdBy WHERE rowstatus=1 and qualId=@original_qualId"
Hi all, first post, and I am desperate. I have a SqlDataSource with a Select, Update and Delete command. From what I understand, scalar variables should be read automatically from the GridView's BoundField columns when it executes a command on it. Here is my code:
I apologize for the way the code is put in, the code thing cut off a lot of the text! The problem I'm getting is, when the 'Update' button is hit, I get the error: Must declare the variable '@TeamId'.
I've tried putting "Update Parameters", that takes away the error, but the row does not update. I've browsed the internet and saw the same problems in lots of areas, but either a) none of the solutions work for me, or b) they don't really apply to my case. I'm using ASP .NET 2.0, and (obviously) C#. SQL Server database. Any help is greatly appreciated. Thanks in advance,
Is there any way I can use a variable from my code behind file in the UpdateCommand of a sqlDataSource? I have tried <%$ strUserGuid %>and<% strUserGuid %> any help appreciated.Thanks Dave
Hi all, I really can't figure out what i'm doing wrong here, and I'd appreciate some help if possible please! SqlDataSource5.InsertParameters("ntuser").DefaultValue = ntuser SqlDataSource5.InsertParameters("datetime").DefaultValue = DateTime.Now SqlDataSource5.Insert()Above is my code to insert into my SQL database a varchar NT user name, and the current date. The Parameters are defined in the HTML as : <asp:SqlDataSource ID="SqlDataSource5" runat="server" ConnectionString="<%$ ConnectionStrings:Test EnvironmentConnectionString %>" InsertCommand="usp_insert_hit" InsertCommandType="StoredProcedure" SelectCommand="usp_select_hits" SelectCommandType="StoredProcedure" UpdateCommand="usp_insert_hit" UpdateCommandType="StoredProcedure"> <InsertParameters> <asp:Parameter Name="ntuser" Type="String" /> <asp:Parameter Name="datetime" Type="DateTime" /> </InsertParameters></asp:SqlDataSource> My SQL Database is set up to have a table called "Hits" which has three colums, a hit_id (Autocounter, primary key), ntuser (varchar), datetime (datetime) When the application runs it stops at runtime and highlights the SQLDataSource5.Insert() line, and I can't figure out why - can anyone else tell why please? thanks.
Here is one such function:CREATE FUNCTION my_max_market_date () RETURNS datetimeBEGINDECLARE @mmmd AS datetime;SELECT max(h_market_date) INTO @mmmd FROM holdings_tmp;RETURN @mmmd;ENDOne change I had to make, relative to what I had working in MySQL, wasto insert 'AS' between my variable and its type. Without 'AS', MS SQLinsisted in telling me that datetime is not valid for a cursor; and Iam not using a cursor here. The purpose of this function is tosimplify a number of SQL statements that depend on obtaining the mostrecent datetime value in column h_market_date in the holdings_tmptable.The present problem is that MS SQL doesn't seem to want to allow me toplace that value in my variable '@mmmd'. I could do this easily inMySQL. Why is MS SQL giving me grief over something that should be sosimple. I have not yet found anything in the documentation for SELECTthat could explain what's wrong here. :-(Any ideas?ThanksTed
Why isn't there some documentation on how to do this. This should be really simple and it has taken me 2 weeks and I still haven't gotten an answer. Please Help Does anyone know the answner or some place where there is some documentation!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I get the following error when I try to substitute the strings in the databasedetails collection with variables: Error: Object reference not set to an instance of an object.

I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me
I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday) 1 1 a b c d e m 1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using where (media.mediaTyple like 'thumbnail' or media.mediaType is null) but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
Anyone know how to write the portion in red in a stored procedure?LEFT OUTER JOIN TITLE AS T ON (POS.TITLE_ID = T.TITLE_ID)JOIN DISTRICT_LOCATIONS AS DL ON (POS.DISTRICT_LOCATION_ID = DL.DISTRICT_LOCATION_ID)WHERE POS.PRIMARY_IND = 1 IF @DISTRICT_LOCATION_ID != 'All' BEGIN and DL.DISTRICT_LOCATION_ID = @DISTRICT_LOCATION_ID ENDIF @ATTENDANCE_STATUS_ID!= 'All' BEGIN and AST.ATTENDANCE_STATUS_ID= @ATTENDANCE_STATUS_ID ENDUNION ALLSELECT DISTINCT 5 AS TAG ,3 AS PARENT ,convert(varchar,getdate(),101) as [ACTIVITY_REPORT!1!REPORT_DATE] ,AX.ACTIVITY_CLASS_ID AS [ACTIVITY!2!ACTIVITY_CLASS_ID] ,NULL AS [ACTIVITY!2!ACTIVITY_NAME]
I am testing SQL Server 7.0. In Stored Proc I try to select a database which name is stored in the variable @databasename. I get the error that it can't open a database @databasename. Can I declare the database object in T-SQL?
/* Get Name of Server & declare variables */ declare @sname varchar(30) declare @db1 varchar(30) declare @db2 varchar(30) declare @db3 varchar(30) declare @dbf1 varchar(30) declare @dbf2 varchar(30) declare @dbf3 varchar(30)
select @sname = rtrim(substring(srvname,5,30)) from sysservers
print 'The name of this server is: ' + @sname
Set @db1 = @sname + 'database1' Set @db2 = @sname + 'database2' Set @db3 = @sname + 'database3' Set @dbf1 = @db1 + 'RL_log' Set @dbf2 = @db2 + 'RL_log' Set @dbf3 = @db3 + 'RL_log'
print @db1 print @dbf1 go
ALTER DATABASE @db1 MODIFY FILE (NAME = @dbf1, MAXSIZE = UNLIMITED) go ALTER DATABASE @db2 MODIFY FILE (NAME = @dbf2, MAXSIZE = UNLIMITED) go ALTER DATABASE @db3 MODIFY FILE (NAME = @dbf3, MAXSIZE = UNLIMITED) go .....
When I run it, I get the following errors: ..... The name of this server is: KANSASCITY KANSASCITYdatabase1 KANSASCITYdatabase1RL_log Server: Msg 170, Level 15, State 1, Line 2 Line 2: Incorrect syntax near '@db1'. Server: Msg 170, Level 15, State 1, Line 1 Line 1: Incorrect syntax near '@db2'. Server: Msg 170, Level 15, State 1, Line 1 Line 1: Incorrect syntax near '@db3'. .....
Don't let the line numbers fool you. They refer to the number of lines since the last 'go' in the script. As you can see, the @db1 and @dbf1 variables are evaluating correctly.
WHAT I AM TRYING TO ACCOMPLISH: I am attempting to change the setting of the Transaction Log to grow to fill up the entire disk. I do not wish to limit the space at this time. I have approximately 200 servers to manage and this script would be most useful in managing them, if it only worked.
Should I be using a different function to change the settings on the Transaction Log? Something other than ALTER DATABASE?
I want to change database in my SQL-script like this: DECLARE @DB_NAME varchar(30) SELECT * FROM @DB_NAME.dbo.TableName, but it is syntactically incorrect. I could use USE (@DB_NAME) but I write Stored Procedure, it is not allowed using USE statement in any Stored Procedures.
I have a MS SQL server DB which stores tables and queries and a MS Access DB which acts as an interface and stores Forms. I am a MS Access Developre and this is my first MS Sql Server DB. I would like to know how can i pass a variable which is an object in a Form (In MS Access DB) to a query in MS SQL?
In MS Access( i mean mdb file which all tables, queries and forms are in one mdb file)it is very easy, for example if you would like to pass idfld from Form of frminfo to a query you can say: Where idname like " & Forms!frminfo!idfld , but it does not work on MS SQL. Would you please tell me how can i use a variable in MS SQL query?
I'm working on a DTS package that runs against development databases. At some point I'll move it to qual for testing, and I'll have to change names of servers and credentials for some of the connections. Can I do that with global variables? BOL aren't very helpful about this.
To be more specific. I'll have one "master" package that will be kicking off other packages. I've found in help that I can use dtsrun to pass variables - so I'm assuming that DBAs moving packages from one environment to another will adjust parameters passed by dtsrun to the "master" package. But how does the "worker" package reference global variable from the "master" package? And how do I reference global variable inside the "worker" package so that it's value is used for any of the properties I see when clicking on "disconnected properties" (like server name or user name)?
Is there some sort of tutorial out there that explains use of global variables?
Basically I am creating a wizard(using forms) within a database to import client files and reformat them into the format that we need.
I have a form that list all 26 column headings that I need and tied to each column headings is a combo box that that lists the column headings from the imported client file.
I need to create a query that either appends it to an already formatted file or creates a new table with the column headings.
The problem is the field headings from the imported file change. This is the sql that I used that doesn't work:
INSERT INTO Formatted_Data ( Field X ) SELECT Imported_Data.Forms![Import Data-3]![Combo33] FROM Imported_Data;
Because Imported_Data.Forms![Import Data-3]![Combo33] is not recognized. I think if I could create a variable to replace the Forms! part then it would work but I do not know how to do this,
I have a simple task flow which takes data from an external table and puts it into a SQL server table. In the SQL server table I have a column which flags the data source. I have set up a variable in the variable window to hold a constant which was the appropriate value for the column. I cannot see how to map the variable I have created to the column in my output table.
Not sure if variables do what I think they do, can anyone give me a simple overview, and point me in the right direction to add my constant into the output table.
Is the only way to get a SSIS variable to change values via a configuration file or table? I thought that at one point in developing some SSIS packages that if I changed the value of a variable in a script that value was then retained.
