inserting problem

Hello, I am having a problem with inserting a value into a table. Here is my code:
sql = "INSERT INTO AnthonyInbox (MessageID, Sender, Subject, Message, Date)"+
"VALUES('" + msgNum + "','" + from + "','" + subject + "','" + mainMsg + "','" + date + " ')";

cmd = new SqlCommand(sql, con);

cmd.ExecuteNonQuery();

msgNum, from, subject, and date are succesfully entered in the table, but mainMsg is blank in the table. I have check that mainMsg contains some string, but for some reasons won't enter the value in the table. Below is the definition of the table:

MessageID varchar 50
Sender varchar 50
Subject varchar 200
Message varchar 8000
Date varchar 50

PLEASE help me

the size may be causing problems, try using a sqlparameter for mainmsg

PHP Code:


		
			
 sql = "INSERT INTO AnthonyInbox (MessageID, Sender, Subject, Message, Date)"+
"VALUES('" + msgNum + "','" + from + "','" + subject + "', @Message ,'" + date + " ')";
cmd = new SqlCommand(sql, con);
cmd.Parameters.Add("@Message", System.Data.SqlDbType.VarChar);
cmd.Parameters["@Message"].Value = mainMsg;
cmd.ExecuteNonQuery();

Personaly i would also like to advise that whenever you need a string longer than 255 in your db to not use varchar but the text type instead, it's a far more efficiant and safer for storing such huge datachunks. It should also increase performance.

Kris,

thank you so very much for your help. I am new with SQL server, so I need a lot of advice

I think I want to try your idea to use text data type instead.
Thanks again

Irma
