临时表如何在事务之前创建然后在事务内使用

Question

我用 c# 编写代码。

我想在事务开始之前创建临时表，然后在事务中使用它，但是当我尝试这样做时，我在事务中收到错误，它表明“表不存在”。正确的做法是什么？

SqlConnection sqlConnection = new SqlConnection( "connstring" );
sqlConnection.Open();

string temp = string.Format( "CREATE TABLE dbo.#temp (id INT);" );
DbCommand command = database.GetSqlStringCommand( temp );
database.ExecuteNonQuery( command ); //here is the problem when I add argument , transaction it works
//fill data in temporary table
//...
// open transaction
SqlTransaction transaction = sqlConnection.BeginTransaction();

//Here I try to read from temp table I have some DbCommand readCommand
database.ExecuteNonQuery( readCommand, transaction ); 

Answer 1

如何仅对语句重新排序，以便在事务内进行表创建：

SqlConnection sqlConnection = new SqlConnection( "connstring" );
sqlConnection.Open();

// open transaction
SqlTransaction transaction = sqlConnection.BeginTransaction();

string temp = string.Format( "CREATE TABLE dbo.#temp (id INT);" );
DbCommand command = database.GetSqlStringCommand( temp );
database.ExecuteNonQuery( command, transaction  ); //here is the problem when I add argument , transaction it works

//Here I try to read from temp table I have some DbCommand readCommand
database.ExecuteNonQuery( readCommand, transaction );

下面的代码可以完美运行。

    static void Main(string[] args)
    {
        string conStr = "Integrated Security=true;Initial Catalog=sushma;server=(local)";

        SqlConnection sqlConnection = new SqlConnection(conStr);
        sqlConnection.Open();

        SqlCommand DbCommand = new SqlCommand("CREATE TABLE dbo.#temp (id INT);", sqlConnection);
        DbCommand.ExecuteNonQuery();

        SqlTransaction transaction = sqlConnection.BeginTransaction();
        DbCommand.CommandText = "SELECT * FROM dbo.#temp";
        DbCommand.Transaction = transaction;
        SqlDataReader dr = DbCommand.ExecuteReader();
        dr.Close();            

        transaction.Commit();
        Console.WriteLine("what is the issue");
        Console.ReadKey();
    }
