How To Update A Column In Input Dataset By SQL Query?
Feb 5, 2007
I'm bothered by an issue of updating a column in input dataset from a update query. It looks like SSIS has a very poor function on this.
Example, I have an input dataset of name, salary, dept_no, and I have another table called departments which has fields of dept_no, Dept_name, basic_salary
now I want to update salary column in input dataset with basic_salary if it's salary is smaller than the basic_salary.
update #tmp set salary = basic_salary where #tmp.salary <departments.basic_salary and #tmp.dept_no = departments.dept_no
how could I impletement this in SSIS package?
I tried with lookup, modify scripts by enabling memory restriction. It doesn't say any error when I save the package, but I never get pass debug.
I have a form that loads a dataset. This dataset is composed from SQL statements using alias and unions. Basically it takes uses data from 3 tables. This dataset also has a alias column called ClientName that consists of either people's name or business name.In addition, the form also consist of a search field that allows user to enter the 'ClientName' to be searched (i.e. to search the alias column). So, my question is how can the alias column be searched (user can also enter % in the search field)Function QueryByService(ByVal searchClientNameText As String) As System.Data.DataSet If InStr(Trim(searchClientNameText), "%")>0 Then searchStatement = "WHERE ClientName LIKE '" & searchClientNameText & "'"Else searchStatement = "WHERE ClientName = @searchClientNameText"End If Dim queryString As String = "SELECT RTrim([People].[Given_Name])"& _"+ ' ' + RTrim([People].[Family_Name]) AS ClientName, [Event].[NumEvents],"& _"[Event].[Event_Ref]"& _"FROM [Event] INNER JOIN [People] ON [Event].[APP_Person_ID] = [People].[APP_Person_ID]"& _searchStatement + " "& _"UNION SELECT [Bus].[Organisation_Name],"& _"[Event].[NumEvents], [Event].[Event_Ref]"& _"FROM [Bus] INNER JOIN [Event] ON [Bus].[APP_Organisation_ID] = [Event].[APP_Organisation_ID] "& _searchStatement ..........End Function
I have the above output. When I try to input this as a dataset to a pie chart I don't get the data lables for two slices of the pie chart. Only one slice will show the values when showing data label option is enabled.
For the Pie chart, I have added Soft, Hard and Primary as Values. I haven't added a Category group or a Series group. Why isn't this showing the data labels for the other slices?
Do I need to transform the dataset so that it has a category and the value like below?
XYZ,  2, Soft 50 XYZ ,  2, Hard, 10 XYZ,  2, Primary, 40
Will this work since it has a define category that I could insert for the chart.
I created a dataset based on a stored procedure. There are nine input parameters. When I click on the preview tab, it is asking me for ten input parameters.
I double checked my dataset on the data tab, and it only shows the expected nine parameters when I look at the parameters tab. I can also run the query without issue from the data tab.
I have no idea why it is asking for an extra parameter on the preview tab. It is a column name that does exist in my database, but is in no way used in the stored procedure in question.
Hi, I was wondering how I can complete a column (which doesnt have an input one) with data. For example:
I have a sql query which bring data of 3 columns
ID | FISRT NAME | LAST NAME 1 MIKE MORGAN 2 SARA JOHANES
So, I will insert that data in a FLAT FILE CONNECTION MANAGER, which I configured with 3 columns and I did the corresponding mapping in the FLAT FILE DESTINTATION.
Now, If I add one more column in the FLAT FILE CONNECTION MANAGER, I will not have it mapped to a input one, obviously. So, what I need is to add one more column to the flat file destination and complete it with zeros values in it.
Probably I can solve this part by introducing a DERIVED COLUMN and there I can configure the zeros that I want to add to the column. But I'm not sure if I can do that without having a input column. So, the question will be, how can I add one column to a flat file which doesnt have a input and introduce any value that I want to it? Hope I was clear Thanks for your help.
I have a stored proc I am updating in an OLEDB Command from the results of a Transform Script Component. The Stored Proc has over 65 input parameters, most of them have a NULL passed in. I dont want to create output columns in the Transform Script Component for all of them to map them from the "Available Input Columns" to "Available Destination Columns".
I want to create 3 or 4 generic Output columns for their data type - say IntegerOutput (datatype Int), DateTimeOut (datatype datetime) and so on. The I want to map these generic columns in the OLEDB Command as Available Input Columns" to multiple "Available Destination Columns" - wherever the datatype matches the input column.
But the OLEDB Command Column Mappings let me map One to One only. This will create a huge and unnecessary workload for me to develop and maintain - when I tell you I have 3 such stored procedures, all of whose interfaces are exactly same and for which I can create similar Output columns in the Transform Script Component.
in my original database have a column which is for "path" ,the record in this column is like → �mms://192.12.34.56/2/1/kbe-1a1.wmv】 this kind of column is about 1202,045 .. I don't think is a easy job to update by person.. it may work but have to do same job 1202,045 times..
I have to change � mms://192.12.34.56/2/1/kbe-1a1.wav】 to � mms://202.11.34.56/2/1/kbe-1a1.wav】 I tried to find the reference book and internet . can't find out the answer for this problem. can you help? or maybe is it a impossible job? thanks
I want to update Flag column in second table based on the Adder names.
If the Applicatiion has atleast one AIX and Adder name is UDB then the flag would be True. If the Application has more the one AIX and Adder names are diferent then the flag would be null.

hi , i am new to this. how should i update the user input values into sql server database? i am using asp.net and c# FIELDS are- userId, name, description, startTime, endTime, audiencePassword, presenterPassword
i know it must be simple...but i haven't worked on this before.
I am a very beginner in SQL and know a little bit VB.
I created a database table with two columns, one for key and the other for data. I'd like to update the data column using excel sheet which contains the same columns, key and data.
Hi, I am trying to figure out how to update a dataset. Below is my sample code but it gives me this error on the mySqlDataAdapter.Update line.Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information. I looked around and it seems like I'm supposed to add a Primary Key but I did that and still get nothing. Below is my page load code... it is based on the quickstart at http://quickstarts.asp.net/QuickStartv20/howto/doc/adoplus/UpdateDataFromDB.aspx but I'm still having trouble and not sure what I'm missing. 1 // Create a new Connection and SqlDataAdapter 2 SqlConnection myConnection = new SqlConnection("Server=localhost;uid=user;pwd=password;database=northwind"); 3 SqlDataAdapter mySqlDataAdapter = new SqlDataAdapter("Select * from Customers", myConnection); 4 DataSet myDataSet = new DataSet(); 5 DataRow myDataRow; 6 7 // Create command builder. This line automatically generates the update commands 8 // for you, so you don't have to provide or create your own. 9 SqlCommandBuilder mySqlCommandBuilder = new SqlCommandBuilder(mySqlDataAdapter); 10 11 // Set the MissingSchemaAction property to AddWithKey because Fill will not cause 12 // primary key & unique key information to be retrieved unless AddWithKey is specified. 13 mySqlDataAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; 14 mySqlDataAdapter.Fill(myDataSet, "Customers"); 15 16 showData(myDataSet); 17 18 // Set PK of table to CustomerID ?? 19 DataColumn[] pk = new DataColumn[1]; 20 pk[0] = myDataSet.Tables["Customers"].Columns["CustomerID"]; 21 myDataSet.Tables["Customers"].PrimaryKey = pk; 22 23 // Edit some data 24 myDataSet.Tables["Customers"].Rows[0]["ContactName"] = "Maria Anders2"; 25 //DataRow myDataRow1 = myDataSet.Tables["Customers"].Rows.Find("ALFKI"); 26 //myDataRow1["ContactName"] = "Maria Anders2"; 27 28 showData(myDataSet); 29 30 //Update DB 31 mySqlDataAdapter.Update(myDataSet, "Customers"); 32 Thanks!
I want to do an update query like the following:UPDATE tblUserDetails SET DeploymentNameID = 102 WHERE (EmployeeNumber = @selectedusersparam)Is there some simple way to add the @selectedusersparam as value1,value2,value3 etc. or do I have to input it with this type of syntax:UPDATE dbo_tblUserDetails SET dbo_tblUserDetails.DeploymentNameID = 102WHERE (((dbo_tblUserDetails.EmployeeNumber)=value1 Or (dbo_tblUserDetails.EmployeeNumber)=value2));Help appreciated.Many thanks.
I'm getting a type mismatch error (currently string, when I think I need Int32 ?) with the code below. I'm having difficultly setting my session variable to type Int32 and having it take up the value of RawCoDeptRowID. When I "Watch" it, it's value remains as "snCoDeptRowID". Also, not sure if my Update command and it's snCoDeptRowID input parameter is well formed? Any advice would be greatly appreciated. Thank you. Web Page 1: Session["snCoDeptRowID"] = Convert.ToInt32 (RawCoDeptRowID);
I have an update statement that accepts a user's text input. problem is that the string terminates the sql update statement if there is an apostrophe in it. so, headline='i like my brother's car" willl terminate after "brother". "s car" is read as sql.
how is this resolved?
Code:
Dim MyCmd2 As New Data.SqlClient.SqlCommand("SET ANSI_WARNINGS OFF " & _ "UPDATE EditProfile " & _ "SET headline='"+ Me.tb_headline.Value+"', about_me='"+ Me.ta_aboutme.Value+"', edit_date='"+System.DateTime.Now.ToString+"' WHERE email_address='"+Context.User.Identity.Name.ToString+"' " & _ "SET ANSI_WARNINGS ON ", MyConn)
I have an OLE DB Command which updates a table. However, the command needs to use the value of an input column more than once.
For example I want to update TableA only if either ColumnA or ColumnB have actually changed: - update tableA set columnA = ?, column B = ? where columnC = ? AND (columnA != ? OR columnB != ?)
I can't map the Input column to more than one parameter so I've been forced to create a copy of columnA and ColumnB as input columns so I can map to the extra paramters that the Command shape expects.
I also attempted to modify the command syntax so it set up variables for the 3 values required and then set the values to parameters - but I get a very unhelpful syntax error message: - declare @ValueA varchar(50), @ValueB varchar(50), @ValueC varchar(50) select @ValueA = ?, @ValueB = ?, @ValueC = ?, update tableA set columnA = @ValueA , column B = @ValueB where columnC = @ValueC AND (columnA != @ValueA OR columnB != @ValueB)
I know this is very very silly.But I am stuck and don't know what to do.I have a simple form which has 1 textbox and a 'Save' button.I have created a Database connection and an Adapter with Dataset withthe help of Wizards.I have binded by text box control to one of the database field.When the form gets loaded it displays the field information correctly."Me.SqlDataAdapter1.Fill(DsBasicData1)"However, when I press the save button it does not update the databasebehind it.I have given the following code to the click event of save button."Me.SqlDataAdapter1.Update(DsBasicData1)"Strangely I don't know why the code does not work.
Is it possible to assign to a column a value passed as a parameter?
When I run the proc I get the following error :

I have a gridview and a dataset. When I start my application I see the results in my gridview. When I clic on edit and chanche some value and click on update it wil give me this error:ObjectDataSource 'ObjectDataSourcePersoon' could not find a non-generic method 'Update' that has parameters: naam, tussenvoegsel, achternaam, adres, woonplaats, telefoonnummer, original_id, Original_naam, Original_tussenvoegsel, Original_achternaam, Original_adres, Original_woonplaats, Original_telefoonnummer. Does someone know whats the problem??
I have a script component and under input columns, I checked one of the fields I want to use inside the script. It's under the Input 0 in the hierarchical tree inside the inputs and outputs.
I'm developing a Destination Component. I need to create the input columns in my ReinitializeMetadata() method. This is a small code sample of the method:
This piece of code works fine, but now i want to use a UI Type DataFlowDestinationUI with a Destination mapping page added by base.AddDestinationMappingsPageToForm( form, "" );.
When I open the mapping page - ReinitializeMetadata() is called BEFORE opening this page - this error is shown:
Code Snippet =================================== Exception from HRESULT: 0xC0047041 (Microsoft Visual Studio) ------------------------------ Program Location: at Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSVirtualInputColumn90.get_UsageType() at Microsoft.DataTransformationServices.DataFlowUI.DataFlowDestinationUI.mappingPage_MapColumns(Object sender, MapColumnsEventArgs args)
I think it's because the mapping page calls GetVirtualInput() itself. Do you know a solution for this problem?
I have dataadapter and dataset that reads/writes to SQL tables. I can read. I can create "new" records. However, I have not been able to master the "updating" of an existing row. Can someone provide me specific code for doing this please or tell me what I doing wrong in the code below. The code I using is below. I don't get error, but changes do not get written to SQL dbase. For starters, I think I "not" supposed to use the 2nd line(....NewRow). I think this is only for new row, not updating of existing row - but I don't know any other way to get schema of row. thanks to any who can help
1) is there any way to run a query over a query without having to create a table with the results of the first query? (would drop table work? If so, how?
2) how can i define input variables the same way i do in excel? I am trying to run a couple of simulations based on 2 core inputs (in excel i would just do a data table)
