Would it be possible to retrieve a "dynamically" named field from a table by using an input parameter?
For example, if a table has fields named Semester1, Semester2, Semester3, Semester4, and I was lazy and only wanted to create one stored procedure for all semesters could I do the following...
ALTER PROCEDURE u_sp_x
@semester int
AS
Select Semester@semester
From ThisTable
Ok 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.
In general, What is the best approach in creating a dynamic updatestored procedure, that can handle recieving varying input paramters andupdate the approporiate columns.
I 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
Hi, I rewrote my working Sql statement to prevent Sql Injections. I copied some code I used in another project but this time I can't get it to work, possibly because it's an update statement and not an Insert one, which I used before. Sorry for the boring question, but does anyone have a clue what's wrong with the syntax? Here's the original code (I changed the parameter names for clarity and security): Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) Dim strSQL As String = "Update MyTable Set " & typ & num & " = '" & pname & "' WHERE personID = " & fid Dim cmd As SqlCommand = New SqlCommand(strSQL, conn) Here's the code from codebehind: Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) Dim strSQL As String = "Update MyTable Set (" & typ & num & ") Values (@" & typ & num & ") WHERE personID = " & fid Dim cmd As New SqlCommand(strSQL, conn) With cmd.Parameters .Add(New SqlParameter("@" & typ & num, pname)) End With TestLabel.Text = strSQL & " " & pname cmd.Connection.Open() cmd.ExecuteNonQuery() cmd.Connection.Close() Here's my test message; first the sql, then the new string to be inserted: Update MyTable Set (picturename) Values (@pname) WHERE personID = 2 2_adin.jpg Here's my error code: Line 1: Incorrect syntax near '('. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '('. Source Error: Line 489: TestLabel.Text = strSQL & " " & pnameLine 490: cmd.Connection.Open()Line 491: cmd.ExecuteNonQuery()Line 492: cmd.Connection.Close()Line 493: End If I could understand it if I'd get an error in VWD Express for using dynamic variables, but they work correctly in the text message so I'm clueless. Any help is deeply appreciated! Pettrer (VB, Sql Server 2000)
I'm trying to generate an update statement based off select statement results. A very basic example,
SELECT ListID FROM DListing WHERE Status = 2Results return 3 rows. 1234 2345 3456
How can I take those results and turn them into WHERE criteria for UPDATE statement?
Generated UPDATE statement should look like this.
UPDATE DListing SET Status = 1 WHERE ListID IN (1234,2345,3456)
I have started by creating a temp table to hold my SELECT results, but I don't know how to get those results into format for IN condition. Right now I get 3 UPDATE statements with 1 ListID in each IN condition.
CREATE TABLE #TempStatusUpdate(ListID INT) INSERT INTO #TempStatusUpdate SELECT ListID FROM DListing WHERE Status = 2 SELECT 'UPDATE DListing SET Status = 1 WHERE ListID IN (' + CONVERT(VARCHAR(30),ListID) + ') AND Status = 2' DROP TABLE #TempStatusUpdate
I have a quick question on SQL Server. Lets say I have table Order which has column names OrderId, CustomerName, OrderDate and NumberofItems. To select the OrderID values from the table I say Select OrderId from Order. But in the select if I want the column name to be variable how do I do it. I tried the following code through a stored procedure.
The code above gave me the string "OrderID" as many times as there were rows in the table but I could never get the actuall values in the OrderId column. Can you please send me some ideas or code where I can get values from the column names and at the same time change the column name dynamically.
In SQL Server you can do a SELECT INTO to create a new table, much like CREAT TABLE AS in Oracle. I'm putting together a dynamic script that will create a table with the number of columns being the dynamic part of my script. Got any suggestions that come to mind?
Example:
I need to count the number of weeks between two dates, my columns in the table need to be at least one for every week returned in my query.
I'm thinking of getting a count of the number of weeks then building my column string comma separated then do my CREATE TABLE statement rather then the SELECT INTO... But I'm not sure I'll be able to do that using a variable that holds the string of column names. I'm guess the only way I can do this is via either VBScript or VB rather then from within the database.
In Dot net 2.0 we change using SQLDataSource to Conect with SQLDB. Now for My case ,the Select SQL is dynamic when differnece user and parameters to the page, So if I want to Update the data input by user,then I must give Update/insert/delelte SQL to SQLDatasource's InsertCommand /UpdateCommand/DeleteCommand . How to Generate the Insert/update/delete command for the SQLDataSource ? as in dot net 1.1 can use SQLCommandBuilder to generate it,but SQLCommandBuilder just support DataAdeptor not for SQLDataSource, Could any body know how to do it when the SelectCommand is dynamic and need to update data back to DB after edit? thanks a lot.
I'm trying to create an interface for filtering profiles from an SQLServer 2005 database using an html form. The form allows filtering based on a minimum level required in between one and four different columns. The first (and only mandatory) column to be filtered on has its name hard-coded into the base query. In trying to get the other three possible criteria to work, I've taken several approaches, all of which failed.The other three potential criteria are selected from a drop down menu on the form and ideally these choices are passed into a query to be used as column names. My first attempt looked like this: query = "SELECT * FROM profiles_tbl WHERE (EngSkill >= @english)" .... if ReqSkill1 <> "" then level1 = Convert.ToInt32(Request.form("minskilllvl1")) query = query & pickclmleft & ReqSkill1 & pickclmright1 cmd.Parameters.Add("@ReqSkill1", SqlDBtype.text) cmd.Parameters("@ReqSkill1").value = ReqSkill1 cmd.Parameters.Add("@level1", SqlDBtype.int) cmd.Parameters("@level1").value = level1 end if above If statement was repeated for 2nd and 3rd optionsSecond approach was to remove all parameters from sections of the query that were appended onto the original statement. This involved lots of strings containing AND clauses with hard-coded column names which were appended on when the corresponding option was selected in the form. Code looked like this: query = "SELECT * FROM profiles_tbl WHERE (EngSkill >= @english)" ASPqry = " AND (ASPlevel >= " try con = new SqlConnection() con.ConnectionString = “**************string was correct****************� cmd = new SqlCommand() cmd.Parameters.Add("@english", SqlDBtype.int) cmd.Parameters("@english").value = english if ReqSkill1 <> "" then if ReqSkill1 = "ASPlevel" then query = query + " AND (ASPlevel >= " level1 = Convert.ToInt32(Request.form("minskilllvl1")) if level1 = 0 then query = query + "0)" end if if level1 = 1 then query = query + "1)" end if if level1 = 2 then query = query + "2)" end if if level1 = 3 then query = query + "3)" end if end if end ifFinally when this too failed, I created four entirely separate queries, detected how many criteria were used, and used the appropriate query, passing necessary skill level in as a parameter. I'll provide code if needed here. Queries were written as strings and then used to set the CommandText property for an SqlCommand variable. I think it's important to note that in all cases the most basic version of the query worked. In the first, if only the first criteria was used the statement executed fine. Same in the second. In the third, whatever query could be assigned first (even though only one could be assigned because of logical structure of if statements) worked and none of the others would. This last case was tested even with completely hard-coded queries that SQL Server 2005 validated as correct and would run. Any help is greatly appreciated. Will post as much code as people want/need, and if I can get any one of these methods working I'll be thrilled. I have no need for all three. A.S. Moser

I have a table which I need to obtain data from but am having a problem with select statement. Specifically, I have a table that has multiple records for a particular hostName where the name of the host is either a shortname (say "Larry") or a long name (say "Larry's"). I need to display only the long names (NOT THE SHORT NAME records with the similar hostName). Select winsHostName, len(winsHostName) from winsData where winsClientIPAddress IN (SELECT winsClientIPAddress from winsData Group By winsClientIPAddress Having count(winsClientIpAddress) > 1) Order by winsHostName Which returns data Name Length ATVDDR 6 ATVDDR1 7 This is a s far as I can get but, Now, I need to list all remaining table fields based on the Name with the longer length and this is where I run into trouble. The output should read per below with the remaining table fields which I cannot seem to extract with nested select statement Name IP Addr Location ATVDDR1 1.1.1.1 2ndFloor I tried adding another GROUP BY by this gets me no where because I do not need to execute another aggregate in select statement. Maybe I need to use INNER JOIN Please advise any assistance.

I am trying to write an update t-SQL statement from the following select statement:
SELECT EduNextContacts.ssn FROM EduNextContacts Left JOIN EduContactsAuditChanges ON EduNextContacts.ssn = EduContactsAuditChanges.ssn AND EduNextContacts.campaign_code = EduContactsAuditChanges.campaign_code GROUP BY EduNextContacts.ssn HAVING(SUM(CASE EduContactsAuditChanges.release_code WHEN '103' THEN 1 ELSE 0 END) + SUM(CASE EduContactsAuditChanges.release_code WHEN '102' THEN 1 ELSE 0 END) >= 2)
I tried many versions of writing my update statement with no luck. My most recent version is as follows:
UPDATE EduNextContacts
SET EduNextContacts.overLMLimit = 'Y'
FROM EduNextContacts Left JOIN
EduContactsAuditChanges ON EduNextContacts.ssn = EduContactsAuditChanges.ssn AND
HAVING(SUM(CASE EduContactsAuditChanges.release_code WHEN '103' THEN 1 ELSE 0 END) +
SUM(CASE EduContactsAuditChanges.release_code WHEN '102' THEN 1 ELSE 0 END) >= 2))
And gives the following error:
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Can anyone help shed some light on how to make an update statement from my SELECT query above?

it posts and the page loads but the data is still the same in my datagrid. what could be wrong with this simple statement... i've tried testing the statement above with constant values of the correct type but i don't think that matters because the SqlCommand() accepts a string only anyways.. doesn't it?
Hello All I have had asked the same question in another post, i didnt get answer to it i might have had asked it wrongfully
Soo the question is: When creating a SQLDataSource in the wizard you get to the pont where you select the option . It says that by using this datasource you can select to update delete and insert. So my question is if i am creating a select statement to reterieve the data from the Table, then what does it do it do if my intention is to only reterie the data. Or what is the other way that it could be helpful to me ??
thanks all I hope it make sence, if not I wrill write another post to bring step by step info into it.
I have a GridView dispalying from a SQLServerDataSource that is using a SQL Select Union statement (like the following):
SELECT FirstName, LastNameFROM MasterUNION ALLSELECT FirstName, LastNameFROM CustomORDER BY LastName, FirstName I am wondering how to create Update and Insert statements for this SQLServerDataSource since the select is actually driving from two different tables (Master and Custom). Any ideas if or how this can be done? Specifically, I want the Custom table to be editable, but not the Master table. Any examples or ideas would be very much appreciated! Thanks, Randy
I've looked up Books Online on Dynamic Cursor/ Dynamic SQL Statement.
Using the examples given in Books Online returns compilation errors. See below.
Does anyone know how to use Dynamic Cursor/ Dynamic SQL Statement?

i 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
