c# - 使用 .NET 连接到 iSeries DB2 数据库

Question

我在从我正在开发的 .net 4.0 应用程序连接到 iseries DB2 数据库时遇到了一些困难。我一直在尝试使用 IBM.Data.DB2.dll 库通过以下代码连接到它；

String connectionString = "Database=[DBName];UserID=[UserID];Password=[Password];Server=[ServerName]";
connection = new DB2Connection(connectionString);
connection.Open();

当 connection.Open() 命令运行时，我收到以下错误:

ERROR [58009] [IBM] SQL30020N Execution of the command or SQL statement failed because of a syntax error in the communication data stream that will affect the successful execution of subsequent commands and SQL statements: Reason Code "0x124C"("0100")"". SQLSTATE=58009

有人知道在 .net 中连接到这种数据库的另一种方法吗？

这对我有用:

class Program
{
    static void Main(string[] args)
    {
        string connString = "DataSource=SYSTEM;UserID=USER;Password=PASSWORD";
        iDB2Connection conn = new iDB2Connection(connString);
        conn.Open();

        string cmdString = "CRTPF FILE(TESTLIB/TESTNET) RCDLEN(100)";
        string cmdText = "CALL QSYS.QCMDEXC('" + cmdString + "', " + cmdString.Length.ToString("0000000000") + ".00000" + ")";

        iDB2Command cmd = new iDB2Command(cmdText, conn);
        cmd.ExecuteNonQuery();
        cmd.Dispose();

        conn.Close();
    }
}
