vssql查询
我给你写一个例子吧，其他功能依次改改就可以实现的：
///
/// 获取数据库连接
///
///
public static SqlConnection GetConnection()
{
string connStr = @"Data Source=WIN-20120404HSE;Initial Catalog=BooksManage;Integrated Security=True";
return new SqlConnection(connStr);
}
//这是增加一天图书信息（你自己建一张表，然后这张表的字段就是你上面列出来的，然后你根据你的表把我写的这个sql语句换成你的就ok了，你先做，如果不懂的话，在追问。）
public void AddTbook(Tbook tbook)
{
string sql = string.Format("insert into Tbook values('{0}','{1}','{2}','{3}','{4}',@bookCover,'{5}','{6}','{7}','{8}') ",
tbook.BookName, tbook.BookTypeId, tbook.BookAuthor, tbook.BookPrice, tbook.BookContent, tbook.BookCode, tbook.BookInLib,tbook.BookPublishTime,tbook.BookPublisher);
SqlConnection conn = null;
try
{
conn = ConnectionManager.GetConnection();
conn.Open();
//获取SqlCommand，封装sql
SqlCommand command = new SqlCommand(sql, conn);
SqlParameter prm = new SqlParameter("@bookCover", SqlDbType.VarBinary, tbook.BookCover.Length, ParameterDirection.Input, false, 0, 0, null, DataRowVersion.Current, tbook.BookCover);
command.Parameters.Add(prm);
//发送SQL
command.ExecuteNonQuery();
}
catch (SqlException)
{
throw new DAOException();
}
finally
{
if (conn != null)
{
conn.Close();
}
}
}
