The data Access assistant divides commonly used database operations methods ExecuteScalar (), ExecuteNonQuery (), and ExecuteReader () into SQL statements and stored procedures in two ways.

When implemented with SQL statements, you can use code similar to the following:

Sqlserverhelper.executesqlnonquery (SQL);//sql as SQL statement

Through the stored procedure is realistic, you can use similar code as follows:

Sqlserverhelper.executesqlnonquery (proc,parameters);//proc stored procedure name, parameter
