SQL Server:数据网格视图显示表中的列值

本文关键字：显示 视图 Server 数据 数据网 网格 SQL | 更新日期: 2023-09-27 18:30:24

我想在datagridview中显示指定的列值。示例：从表user_account我想按文本框显示和搜索数据网格视图中列account中的数据

这是到目前为止的代码：

private void button3_Click(object sender, EventArgs e)
{
        string connectionString = @"Data Source=" + textBox4.Text + ";" + "Initial Catalog=" + textBox1.Text + ";" + "User ID=" + textBox2.Text + ";" + "Password=" + textBox3.Text;
        string sql = "SELECT * FROM user_account";
        SqlConnection connection = new SqlConnection(connectionString) ;
        SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);
        DataSet ds = new DataSet();
        connection.Open();
        dataadapter.Fill(ds, "account");
        connection.Close();
        dataGridView1.DataSource = ds;
        dataGridView1.DataMember = "account";
    }

SQL Server:数据网格视图显示表中的列值

private void button3_Click(object sender, EventArgs e)
    {
        string connectionString = @"Data Source=" + textBox4.Text + ";" + "Initial Catalog=" + textBox1.Text + ";" + "User ID=" + textBox2.Text + ";" + "Password=" + textBox3.Text;
        string sql = "SELECT account FROM user_account";
        SqlConnection connection = new SqlConnection(connectionString) ;
        SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);
        DataSet ds = new DataSet();
        connection.Open();
        dataadapter.Fill(ds, "account");
        connection.Close();
        dataGridView1.DataSource = ds;
    }

解决方案：

        private void button3_Click(object sender, EventArgs e)
    {
        string connectionString = @"Data Source=" + textBox4.Text + ";" + "Initial Catalog=" + "lin2db" + ";" + "User ID=" + textBox2.Text + ";" + "Password=" + textBox3.Text;
        string sql = "SELECT account ,pay_stat FROM user_account where account='" + textBox7.Text + "' ";          
        SqlConnection connection = new SqlConnection(connectionString) ;
        SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);
        DataSet ds = new DataSet();
        connection.Open();
        dataadapter.Fill(ds, "pay_stat");
        connection.Close();
        dataGridView1.DataSource = ds;
        dataGridView1.DataMember = "pay_stat";

    }

谢谢你的帮助。
