C# 通过SqlReader HasRows判断指定表中是否有数据
本例主要是判断指定的数据库数据表中是否有数据,这里使用了通过判断HasRows的返回值来判断,若返回值为真,则有数据,反之则无数据,最后用MessageBox.Show显示判断结果,完整的过程:
//实例化SqlConnection变量conn
SqlConnection conn = new SqlConnection("server=.;database=db_14;uid=sa;pwd=");
conn.Open();//打开连接
//创建一个SqlCommand对象
SqlCommand cmd = new SqlCommand("select * from " + textBox1.Text.Trim(), conn);
//使用ExecuteReade方法创建SqlDataReader对象
SqlDataReader sdr = cmd.ExecuteReader();
sdr.Read();//调用Read方法读取SqlDataReade
if (sdr.HasRows)//使用HasRows属性判断结果中是否有数据
{
MessageBox.Show("数据表中有值");//弹出提示信息
}
else
{
MessageBox.Show("数据表中没有任何数据");
}
