  • Convert byte to boolean string in HyperLinkField.DataNavigateUrlFormatString

    - by abatishchev
    I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1} Select command of appropriate SqlDataSource returns columns of type INT and BYTE (from SQL Server 2008). So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant(). How to implement such conversion in page markup?

  • how to generate the "create table" sql statement for an existing table in postgreSQL

    - by Raja
    I have a table created long ago in postgreSQL. Now i want to look at the sql statement used to create it but cannot figure it out. Also when i do the \dS+ tablename it says table not found, but \dt+ tablename is working fine. The \dS+ lists all the table names owned by the root postgres user and doesn't show up tables that i created with my user account. Any help is greatly appreciated. Thanks

    I have a gridview setup that gets its data from a SQL database stored procedure. This procedure will return one of several different tables. The gridview complains if the table is different than the one previously displayed. How do I work around this?

  • Update a column based on a field from another table

    - by Sergio
    Hi: I'd like to update values in one table based on corresponding values from other tables. Say you want to update prices of pieces provided by one specific manufacturer whose name is in the table Manufacturers with the Pieces table containing only the id of the manufacturer. I've seen several solutions for MySQL here and for MS SQL Server here but none of them seems to work in SQLite. Any suggestion?

  • DataGridView live display of datatable using virtual mode

    - by Chris
    I have a DataGridView that will display records (log entries) from a database. The amount of records that can exist at a time is very large. I would like to use the virtual mode feature of the DataGridView to display a page of data, and to minimize the amount of data that has to be transferred across a network at a given time. Polling for data is out of the question. There will be several clients running at a time, all of which are on the same network and viewing the records. If they all poll for data, the network will run very slowly. The data is read-only to the user; they won't be able to edit any of it, just view it. I need to know when updates occur in the database, and I need to update the screen with those updates accordingly using virtual mode. If a page of data a user is viewing contains data that has change, he/she will see those updates on that page. If updates were made to data in the database, but not in the data the user is viewing, then not much really changes on the user screen (Maybe just the scroll bar if records were added or removed). My current approach is using SQL server change tracking with the sync framework. Each client has a local SQL Server CE instance and database file that is kept in sync with the main database server. I use the information from the synchronization event to see if any changes were made to the main database and were sync'ed to the client. I need to use the DataGridView virtual mode here because I can't have thousands of records loaded into the DataGridView at once, otherwise memory usage goes through the roof. The main challenge right now is knowing how to use virtual mode to provide a seamless experience to the user by allowing them to scroll up and down through the records, and also have records update on the fly without interfering with the user inappropriately. Has anybody dealt with this issue before, and if so, where I can see how they did it? I've gone through some of the MSDN documentation and examples on virtual mode. So far, I haven't found documentation and/or examples on their site that explains how to do what I am trying to accomplish.

  • Where can I get a machine readable representation of world currencies and their symbols?

    - by Khanzor
    I'm using ASP.Net and would like to display currencies based on a country. I've had a look at http://www.xe.com/symbols.ph, http://www.xe.com/iso4217.php and http://www.iso.org/iso/support/faqs/faqs_widely_used_standards/widely_used_standards_other/currency_codes/currency_codes_list-1.htm Is there anywhere I can get something that I can load into a database? Or is there something built in to SQL Server 2005/ASP.Net to help with this?

  • JSON datetime to SQL Server database via WCF

    - by moikey
    I have noticed a problem over the past couple of days where my dates submitted to an sql server database are wrong. I have a webpage, where users can book facilities. This webpage takes a name, a date, a start time and an end time(BookingID is required for transactions but generated by database), which I format as a JSON string as follows: {"BookingEnd":"\/Date(2012-26-03 09:00:00.000)\/","BookingID":1,"BookingName":"client test 1","BookingStart":"\/Date(2012-26-03 10:00:00.000)\/","RoomID":4} This is then passed to a WCF service, which handles the database insert as follows: [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, UriTemplate = "createbooking")] void CreateBooking(Booking booking); [DataContract] public class Booking { [DataMember] public int BookingID { get; set; } [DataMember] public string BookingName { get; set; } [DataMember] public DateTime BookingStart { get; set; } [DataMember] public DateTime BookingEnd { get; set; } [DataMember] public int RoomID { get; set; } } Booking.svc public void CreateBooking(Booking booking) { BookingEntity bookingEntity = new BookingEntity() { BookingName = booking.BookingName, BookingStart = booking.BookingStart, BookingEnd = booking.BookingEnd, RoomID = booking.RoomID }; BookingsModel model = new BookingsModel(); model.CreateBooking(bookingEntity); } Booking Model: public void CreateBooking(BookingEntity booking) { using (var conn = new SqlConnection("Data Source=cpm;Initial Catalog=BookingDB;Integrated Security=True")) using (var cmd = conn.CreateCommand()) { conn.Open(); cmd.CommandText = @"IF NOT EXISTS ( SELECT * FROM Bookings WHERE BookingStart = @BookingStart AND BookingEnd = @BookingEnd AND RoomID= @RoomID ) INSERT INTO Bookings ( BookingName, BookingStart, BookingEnd, RoomID ) VALUES ( @BookingName, @BookingStart, @BookingEnd, @RoomID )"; cmd.Parameters.AddWithValue("@BookingName", booking.BookingName); cmd.Parameters.AddWithValue("@BookingStart", booking.BookingStart); cmd.Parameters.AddWithValue("@BookingEnd", booking.BookingEnd); cmd.Parameters.AddWithValue("@RoomID", booking.RoomID); cmd.ExecuteNonQuery(); conn.Close(); } } This updates the database but the time ends up "1970-01-01 00:00:02.013" each time I submit the date in the above json format. However, when I do a query in SQL server management studio with the above date format ("YYYY-MM-DD HH:MM:SS.mmm"), it inserts the correct values. Also, if I submit a millisecond datetime to the wcf, the correct date is being inserted. The problem seems to be with the format I am submitting. I am a little lost with this problem. I don't really see why it is doing this. Any help would be greatly appreciated. Thanks.

  • Comparing XML in SSRS

    - by silves89
    I'm new to SSRS. We'll have two slightly different chunks of XML in a single row of an SQL Server database table. In an SSRS report we'll want to show only the differences between the XML chunks. I don't know how to do this, but I suspect the XML Type in SQLServer 2005 might be useful, or XSLT transformations in SSRS. Could anyone point me in the right direction?

  • Transforming OLTP Relational Database to Data Warehousing Model

    - by Russ Cam
    What are the common design approaches taken in loading data from a typical Entity-Relationship OLTP database model into a Kimball star schema Data Warehouse/Marts model? Do you use a staging area to perform the transformation and then load into the warehouse? How do you link data between the warehouse and the OLTP database? Where/How do you manage the transformation process - in the database as sprocs, dts/ssis packages, or SQL from application code?
