Question

我正在尝试使用.Net与以下代码连接Teradata。

但是当我执行它时，它会抛出一个错误，指出无效的连接字符串 在

Eclipse Oxygen 4.7.0

这里是完整的代码

TdDataAdapter adapter = new TdDataAdapter(cn.ConnectionString,cmd.CommandText);

我尝试使用using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using Teradata.Client.Provider; using System.Data; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { TdConnectionStringBuilder connectionStringBuilder = new TdConnectionStringBuilder(); connectionStringBuilder.DataSource = "URK"; connectionStringBuilder.Database = "DB"; connectionStringBuilder.UserId = "USERNAME"; connectionStringBuilder.Password = "PASSWORD"; connectionStringBuilder.AuthenticationMechanism = "LDAP"; TdConnection cn = new TdConnection(); cn.ConnectionString = connectionStringBuilder.ConnectionString; cn.Open(); TdCommand cmd = new TdCommand("EXEC MACRONAME", cn); TdDataReader reader = cmd.ExecuteReader(); TdDataAdapter adapter = new TdDataAdapter(cn.ConnectionString,cmd.CommandText); DataSet ds = new DataSet(); adapter.Fill(ds); myLabel.Text= ds.Tables[0].Rows[0]["event_id"].ToString(); cmd.Dispose(); cn.Close(); } }而不是上面使用的那个，但我仍然遇到了同样的错误。

Answer 1

只需交换参数

TdDataAdapter adapter = new TdDataAdapter(cmd.CommandText, cn.ConnectionString);

根据TdDataAdapter构造函数的签名

public TdDataAdapter( 
   string commandText,
   string connectionString
)

请参阅docs
