I have a problem with the value returned from SqlCommand , I have this code: string sqlSelect = "Select TOP 1 Quotation.SentToSupp as SentToSupp FROM Quotation JOIN Notifications ON Quotation.QuotationId = QuotationID "; SqlCommand Comm = new SqlCommand(sqlSelect, this.Connection); sqlSelect query selects the first DateTime value. When I call to SqlCommand I want to get this value (just one value). I add the query and my connection fine. But I don't know how to get my DateTime value... Must to use something like ExecuteReader ? Thank you in advance!! Use SqlCommand.ExecuteScalar method -

I'm creating a web application that serves as a front end to do SQL Replication. I have many scripts stored in the properties of the program. Let's use the first one as an example. The first script is the script that you get from creating a publication on the publisher server. USE [<<SOURCE_DATABASE_NAME>>] EXEC sp_replicationdboption @dbname = N'<<SOURCE_DATABASE_NAME>>', @optname = N'publish', @value = N'true' GO USE [<<SOURCE_DATABASE_NAME>>] EXEC [<<SOURCE_DATABASE_NAME>>].sys.sp_addlogreader_agent @job_login = N'XXX\Admin', @job_password = NULL, @publisher_security_mode = 0, @publisher

I am attempting to execute an SQL Command through a 'using' code block, but can't seem to get it to work with Parameters. I get the error: 'Parameters does not exist in the current context', does anyone have a possible solution for this problem? Heres My code: DataTable dt = new DataTable(); using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString)) using (var cmd = new SqlCommand(" SELECT FName" + " FROM EmployeeTable " + " WHERE EmployeeId = @empId", con) { Parameters.Add(new SqlParameter("@empId",empId)) }) { try { con.open(); dt.Load

I need to programmatically create a SQL Server 2008 table in C# such that the columns of the table should be generated from a list of columns (each column name is the name of a row in the table) My question is what is the command string to loop through the list of columns and creates the table's recorded: List<string> columnsName = ["col1","col2","col3"] I want to create a table with the columns in the columnsName . But since the list size in not constant, I need to loop through the list to generate the table columns. The simple answer is CREATE TABLE table_name ( column_name1 data_type,

Possible Duplicate: C# Update Table using SqlCommand.Parameters I'm trying to update an SQL Server table using SqlCommand, I think it's a syntax error with my T-SQL, but here is what I have so far: SqlCommand sqlCmd = new SqlCommand( "UPDATE yak_tickets SET email = @emailParam, subject = @subjectParam, text = @textParam, statusid = @statusIDParam, ticketClass = @ticketClassParam WHERE id = @ticketIDParam", sqlConn); The parameters are working as they should, however, the table never gets updated when I run the code. Any help would be appreciated =) Here is the rest of the code: #region

Am looking to use an approach in saving passwords that requires using byte array as in this post So which data type should i use in sql server to save byte array? and how can i pass and retrieve the byte array using SqlCommand? If it's always going to be the same length, then binary(length) would be suitable. If it's going to vary in length, use varbinary(maxlength) . binary and varbinary . And, as @p.s.w.g says, you pass it from code by placing it into a suitable parameter. Just use a byte[] the same way you would any other parameter, specifying SqlDbType.Binary as the parameter type. Here a

I am currently creating a WCF web service. As part of its job, it will unfortunately need to do some fairly intensive computations, however these computations can fortunately be shared between calls to the webservice. In effect - we only need to do the computations once, and all later calls can get the benefit. However, since WCF has no shared application state it seems logical to set WCF in single-instance mode. (Each client would require some of the computations in all likelyhood, forcing us to recompute them per-serssion which could be ok, or per-call which is untenable) However, I am not

I'm trying to insert a database record inside a loop in C#. It works when I hard code the values like this: string query3 = "INSERT INTO furniture (room_id,member_id) VALUES (222,333);"; SqlCommand cmd3 = new SqlCommand(query3, sqlConnection3); sqlConnection3.Open(); for (int i = 0; i < arrItemsPlanner.Length; i++) { try { cmd3.ExecuteNonQuery(); } catch { return "Error: Item could not be saved"; } finally { //Fail } } But when I use parameterised queries it doesn't work - even if I hard code a value into the parameterised query like this: string query3 = "INSERT INTO furniture (room_id,member
