Pass NVARCHAR (or Other String-type) Var As A Column Or Table Name In SQL
Jun 21, 2004
Hey folks, the question is fairly simple, unfortunately the answer has proven rather elusive.
Is it possible to declare a variable which would then be used to identify either a column or table in an SQL statement?
Here's a basic idea of what I'd like to do:
DECLARE @myVar AS NVARCHAR(50)
SELECT *
FROM @myVar
or
DECLARE @myVar AS NVARCHAR(50)
SELECT @myVar
FROM MyTable
I'm probably looking for some sort of built in function that will accept an argument here... like COLUMN(@myVar) or something of the like. I just don't know where to look...
I have a stored procedure that contains a paramteter of type nvarchar(max). What is the syntax to pass this parameter to the sp from a VB.Net application. Specifically, I need to know what to put in the 3rd parameter below:
Problem about pass a big string (over 8000 characters) to a variable nvarchar(max) in stored procedure in SQL 2005! I know that SQL 2005 define a new field nvarchar(max) which can stored 2G size string. I have made a stored procedure Hellocw_ImportBookmark, but when I pass a big string to @Insertcontent , the stored procedure can't be launch! why? create procedure Hellocw_ImportBookmark @userId varchar(80), @FolderId varchar(80), @Insertcontent nvarchar(max) as declare @contentsql nvarchar(max); set @contentsql=N'update cw_bookmark set Bookmark.modify(''declare namespace x="http://www.hellocw.com/onlinebookmark"; insert '+ @Insertcontent+' as last into (//x:Folder[@Id="'+@FolderId+'"])[1]'') where userId='''+@userID+''''; exec sp_executesql @contentsql;
as declare @contentsql nvarchar(max); set @contentsql=N'update cw_bookmark set Bookmark.modify(''declare namespace x="http://www.hellocw.com/onlinebookmark"; insert '+ @Insertcontent+' as last into (//x:Folder[@Id="'+@FolderId+'"])[1]'') where userId='''+@userID+''''; exec sp_executesql @contentsql;

Hi, I have a webform with a drop-down listbox, binded to a table and a GridView, binded to another table. My goal is when I select a value (country in my case) in the drop-down listbox to change what is shown in the GridView, based on the ID that I get from the drop-down listbox. Here is the code (the important parts...): Select a Country : <asp:DropDownList ID="CountriesDropDownList" runat="server" DataSourceID="SqlDataSource2" DataTextField="Name" DataValueField="CountryID" Width="220px" AutoPostBack="True"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" SelectCommand="SELECT [CountryID], [Name] FROM [DS_Country]"> </asp:SqlDataSource> <asp:GridView ID="ProvincesGridView" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="ProvinceID,CountryID,Name,ShortName,Description" DataSourceID="SqlDataSource1" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" HorizontalAlign="Left" > <Columns> .............................. </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DineSelectConnectionString %>" DeleteCommand="DELETE FROM DS_Province WHERE ProvinceID=@ProvinceID" SelectCommand="SELECT ProvinceID,CountryID,Name,ShortName,Description FROM DS_Province WHERE CountryID=@ddlCountryID" UpdateCommand="UPDATE DS_Province SET CountryID=@CountryID,Name=@Name,ShortName=@ShortName,Description=@Description WHERE ProvinceID=@ddlCountryID" InsertCommand="INSERT INTO DS_Province (CountryID,Name,ShortName,Description) VALUES (@CountryID,@Name,@ShortName,@Description)"> <SelectParameters> <asp:ControlParameter Name="ddlCountryID" ControlID="CountriesDropDownList" PropertyName="DataValueField" /> </SelectParameters> </asp:SqlDataSource>
When I run it I get this error "Syntax error converting the nvarchar value 'CountryID' to a column of data type int.". If I specify the Type="Int" in <asp:ControlParameter>..</> I get "Input string was not in a correct format. " This is supposed to be easy, but I can't make it work ! Any suggestions will be more than welcome. Thanks.
I am reading data from another data source and storing it in the sqlce database. Some of the string values I'm trying to insert into the database have single quotes in the string (i.e. Johnny's Company). When I try to insert the values with the single quotes, it throws an exception. The code I use to insert the records is as follows:
cmd.CommandText = "INSERT sy_company " +
" (company_id, company, co_name, companyid) " +
"VALUES(" +
"'" + dtSYCompany.Rows[x]["company_id"] + "'," +
"N'" + dtSYCompany.Rows[x]["company"] + "'," +
"N'" + dtSYCompany.Rows[x]["co_name"] + "'," +
"'" + dtSYCompany.Rows[x]["companyid"] + "')";
cmd.ExecuteNonQuery();
When the company name (co_name) has a single quote in it, I get the error. How do I write the insert statement so it will work even though the value being inserted into co_name has a single quote in it?
Hi, all I'm getting this error at runtime when my page tries to populate a datagrid. Here's the relevant code. First, the user selects his choice from a dropdownlist, populated with a sqldatasource control on the aspx side:<asp:SqlDataSource ID="sqlDataSourceCompany" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [PayrollCompanyID], [DisplayName] FROM [rsrc_PayrollCompany] ORDER BY [DisplayName]"> </asp:SqlDataSource> And the dropdown list's code:<asp:DropDownList ID="ddlPayrollCompany" runat="server" AutoPostBack="True" DataSourceID="sqlDataSourcePayrollCompany" DataTextField="DisplayName" DataValueField="PayrollCompanyID"> </asp:DropDownList> Then, I use the selectedindexchanged event to bind the data to the datagrid. Here's that code: 1 Sub BindData() 2 3 Dim ds As New DataSet 4 Dim sda As SqlClient.SqlDataAdapter 5 Dim strSQL As String 6 Dim strCon As String 7 8 strSQL = "SELECT [SocialSecurityNumber], [Prefix], [FirstName], [LastName], [HireDate], [PayrollCostPercent], " & _ 9 "[Phone], [BadgeNumber], [IsSupervisor], [SupervisorID], [IsUser], [IsScout] FROM [rsrc_Personnel] " & _ 10 "WHERE ([PayrollCompanyID] = @PayrollCompanyID)" 11 12 strCon = "Data Source=DATASOURCE;Initial Catalog=DATABASE;User ID=USERID;Password=PASSWORD" 13 14 sda = New SqlClient.SqlDataAdapter(strSQL, strCon) 15 16 sda.SelectCommand.Parameters.Add(New SqlClient.SqlParameter("@PayrollCompanyID", Me.ddlPayrollCompany.SelectedItem.ToString())) 17 18 sda.Fill(ds, "rsrc_Personnel") 19 20 dgPersonnel.DataSource = ds.Tables("rsrc_Personnel") 21 dgPersonnel.DataBind() 22 23 End Sub 24
I'm assuming my problem lies in line 16 of the above code. I've tried SelectedItemIndex, SelectedItemValue too and get errors for those, as well. What am I missing? Thanks for anyone's help! Cappela07

I'm still plunking away on a history trigger that requires the evaluation of whether or not each column has been updated. If it has,t hen I'll be tossing a record into a history table.
Basically I need something to function along the same logic as this:
IF UPDATED(@s) BEGIN --some code END
Any thoughts you folks may have are greatly appreciated.

Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time.

I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;

I want to create a table. One of the columns should be in the data type MONEY with two digits on the right side of the decimal point. How is that possible?
How would I best go about changing a published table's column from smallint to int? I could not find anything about it in BOL or MS.com. I do not think EM/Replication Properties allows the change. I suspect I have to run "Alter Table/Column" on the Publisher and each Subscriber the old-fashioned way. Is that true?
I am using SQL Server 2000 Enterprise Edition fully patched. Database is in Simple Recovery mode.
I need to change a column's data type from "int(4)" to "smallint(2)". I know for sure that there will be no data (precision) lost, because I know the possible values that this column could have.
My problem is that the table I am dealing with has 600,000,000 records in it. I dropped all indexes before I tried to alter the table. But still it is taking forever and filling up my 280GB disk with transaction log file.
I know that in Oracle, if I want I can turn off logging and do these kind of modifications relatively faster.
I was wondering if there is a way of disabling logging before running this alter command.
What is the best practice to handle a situation of this sort?
I uploading an image from a web page into Sql Server 2000 database. I call a stored procedure with the parameter @Flag of type Image. When I tried to pass a null value to this parameter I got the error:"Operand type clash: nvarchar is incompatible with image".I was adding the parameter like this:sqlCmd.Parameters.AddWithValue("@Flag", DBNull.Value);After trying few different things I found a workaround using the following:sqlCmd.Parameters.Add("@Flag", SqlDbType.Image);sqlCmd.Parameters["@Flag"].Value = DBNull.Value;Possibly a bug in the SqlCommand.Parameters.AddWithValue method ?
