executenonquery

I started learning C# last week and I'm now having trouble with an INSERT sql statement. I used the following code, then I tell you what happens. private void AddNewUserToDataBase(User user) { string commandText = "INSERT INTO User (firstName,lastName,adress,town,favoriteCurrency) " + "VALUES (@firstName,@lastName,@adress,@town,@favoriteCurrency)"; using (SqlConnection connection = new SqlConnection(global::Laboratoire1.Properties.Settings.Default.Database1ConnectionString)) { using (SqlCommand command = new SqlCommand()) { command.Connection = connection; command.CommandText = commandText;

Can you please tell me what's wrong with this code? Do I need to use DataAdapter to insert into a table? I know the connectionString is ok, because I tested it on the Server Explorer. Dim mydao As New Connection Dim connectionString As String = mydao.GetConnectionString() Dim connection As New SqlConnection(connectionString) Dim cmd As New SqlCommand Public Function add(ByVal area As String, ByVal user As String) As Integer cmd.CommandText = "INSERT into Area (Area, user) VALUES ('" + area + "','" + user + "')" Try connection.Open() Dim cant As Integer = cmd.ExecuteNonQuery()'it throws

I have to clear certain tables in the oracle database however when I'm having issues with running the following code public static void ClearDataTables(IList<string> tableNames) { string connectionString = "CONNECTIONSTRING"; using (OracleConnection connection = new OracleConnection()) { connection.ConnectionString = connectionString; connection.Open(); foreach (string table in tableNames) { OracleCommand command = connection.CreateCommand(); string sql = String.Format("DELETE FROM TOA_REPORTING.{0}", table); command.CommandText = sql; command.ExecuteNonQuery(); } connection.Close(); } } I am

Ive used this method before to return the amount of rows changed. I am it to run an insert method, the insert runs fine in the stored procedure, but the return value from the ExecuteNonQuery always returns -1. Here is my C# code: int ret = 0; using (SqlConnection conn = new SqlConnection(this.ConnectionString)) { using (SqlCommand cmd = new SqlCommand(QueryName, conn)) { conn.Open(); if (Params != null) cmd.Parameters.AddRange(Params); cmd.CommandType = CommandType.StoredProcedure; ret = cmd.ExecuteNonQuery(); conn.Close(); } } return ret; Why do I get -1 instead of the actual number of rows

I am trying to insert > 8000 characters (submit from a web page) via ExecuteNonQuery (and DatabaseFactory.CreateDatabase() from MS Practices Enterprise Library). The stored procedure defines the parameter as VARCHAR(MAX) . The column is VARCHAR(MAX) . In theory, 2GB of data should be able to be passed. What can I do to pass data > 8000? I set a breakpoint and the string.Length is indeed > 8K. public static void UpdateTerms(string terms) { Database db = DatabaseFactory.CreateDatabase(); db.ExecuteNonQuery("uspUpdateTerms", terms); } Stored procedure: ALTER PROCEDURE [dbo].[uspUpdateTerms]

Simple question, is it possible to achieve this query this with Entity Framework when updating one entity? update test set value = value + 1 where id = 10 Not really under this form no. You will have to select all entities that match your criteria, foreach over them and update them. If you are looking for something that will do it right in the DB because your set could be huge, you will have to use SQL directly. (I don't remember if EF has a way to execute UPDATE queries directly the way Linq To SQL does). Use the Batch Update feature of the Entity Framework Extended Library , like this:

I have a problem while using ExecuteNonQuery . This is my code : var connString = @"Data Source=serwer01;Initial Catalog=PolsatCyfrowy;Integrated Security=True"; FileInfo file = new FileInfo("C:\\Users\\azbudniewek\\source\\repos\\UM2 V2\\UM2 V2\\scripts.sql"); string script = file.OpenText().ReadToEnd(); SqlConnection conn = new SqlConnection(connString); Server server = new Server(new ServerConnection(conn)); server.ConnectionContext.ExecuteNonQuery(script); And this is the error: System.IO.FileNotFoundException: The file or set 'Microsoft.SqlServer.BatchParser, version = 14.100.0.0, Culture

I'm writing a small program in C# that uses SQL to store values into a database at runtime based on input by the user. The only problem is I can't figure out the correct Sql syntax to pass variables into my database. private void button1_Click(object sender, EventArgs e) { int num = 2; using (SqlCeConnection c = new SqlCeConnection( Properties.Settings.Default.rentalDataConnectionString)) { c.Open(); string insertString = @"insert into Buildings(name, street, city, state, zip, numUnits) values('name', 'street', 'city', 'state', @num, 332323)"; SqlCeCommand cmd = new SqlCeCommand(insertString,
