C＃在mysql查询参数中转义表名称中的字符

Question

I'm making a simple mysql client to send some data. I need my tables to have the date as a name in this format: 2014-07-04

I know I have to wrap them around backticks(`) because of the (-). Here's my code:

    public bool Update()
    {
        try
        {                
            MySqlCommand cmd = connection.CreateCommand();
            cmd.Parameters.AddWithValue("@TbName", "");
            foreach (Employee emp in this.employees)
            {
                foreach(shift singleShift in emp.shifts) 
                {
                    cmd.CommandText = "CREATE TABLE IF NOT EXISTS @TbName (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, Name VARCHAR(40), aStart VARCHAR(5), aStop VARCHAR(5), Lunch VARCHAR(5), B1 VARCHAR(5), B2 VARCHAR(5), B3 VARCHAR(5));";                                                                    
                    cmd.Parameters["@TbName"].Value = singleShift.aDate; // singleShift.aDat = 2014-07-24                       
                    cmd.ExecuteNonQuery();            
                }
            }
        }
        catch (Exception ex)
        {
            return false;
        }
            return true;
    }

If I use this code, I get this error:

 You have an error in your SQL syntax; check the manual that corresponds to your MySQL       server version for the right syntax to use near ''2014-06-29' (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, Name VARCHAR(40), aSta' at line 1

So I've tried with a few methods to solve this like using "`" to concatenate the parameter but I get this error:

 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''\`2014-06-29\`' (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, Name VARCHAR(40), ' at line 1

and using MySqlHelper.EscapeString I get this error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''\\\`2014-06-29\\\`' (id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, Name VARCHAR(40), ' at line 1

I know my tables should be named otherwise, but it is not possible in the current context. What can I do to solve this?

Answer 1

create a table with date name

No, you can't use date as table name especially with -. Change to something else.
