使用 Dynamics AX 2009 业务连接器创建表并检索查询结果

Question

我正在编写一个 C# 命令行工具来从 AX 获取数据并向 AX 添加数据（创建新表）。

从 AX 表获取数据非常简单，并在此处记录：http://msdn.microsoft .com/en-us/library/cc197126.aspx

将数据添加到现有表也很容易：http://msdn.microsoft.com/en-us/library/aa868997.aspx

但我不知道如何做两件事：

• 创建一个新的 AX 表
• 从 AX 查询检索数据

有人可以分享一些示例代码或提供一些关于从哪里开始查找的指示吗？我在 Google 和 MSDN 上的搜索并没有透露太多信息。

注意：我不是经验丰富的 AX 或 ERP 开发人员。

Answer 1

我在 AOT 中创建了一个查询，并且能够使用 C# 返回数据。找到下面的代码。这是一个返回我用来创建老化桶的销售额的查询。我希望这有帮助。

[DataMethod(), AxSessionPermission(SecurityAction.Assert)]
public static System.Data.DataTable GetCustBuckets(String AccountNum)
{
    //Report Parameters
    Dictionary<string, object> d = new Dictionary<string, object>();
    d.Add("CustTransOpen.AccountNum",AccountNum);

    // Create a data table. Add columns for item group and item information. 
    DataTable table = new DataTable();
    table = AxQuery.ExecuteQuery("SELECT * FROM epcCustomerAging",d);


    DataTable tableBucket = new DataTable();
    DataRow rowBucket;

    tableBucket.Columns.Add("Current", typeof(double));
    tableBucket.Columns.Add("Bucket31to60", typeof(double));
    tableBucket.Columns.Add("Bucket61to90", typeof(double));
    tableBucket.Columns.Add("Bucket91to120", typeof(double));
    tableBucket.Columns.Add("Over120", typeof(double));

    //Variables to hold BUCKETS
    double dCurrent = 0;
    double dBucket31to60 = 0;
    double dBucket61to90 = 0;
    double dBucket91to120 = 0;
    double dOver120 = 0;

    // Iterate through the results. Add the item group to the data table. Call the display method 
    foreach (DataRow TransRow in table.Rows)
    {

        DateTime TransDate = Convert.ToDateTime(TransRow["TransDate"].ToString());
        double AmountCur = Convert.ToDouble(TransRow["AmountCur"].ToString());

        DateTime Today= Microsoft.VisualBasic.DateAndTime.Now;
        long nDays = Microsoft.VisualBasic.DateAndTime.DateDiff(Microsoft.VisualBasic.DateInterval.Day, TransDate, Today, 0, 0);

        if (nDays <= 30)
        {               
            dCurrent += AmountCur; 
        }
        else if (nDays <= 60)
        {
             dBucket31to60 += AmountCur ; 
        }
        else if (nDays <= 90)
        {
            dBucket61to90 += AmountCur;
        }
        else if (nDays <= 120)
        {
            dBucket91to120 += AmountCur;
        }
        else
        {
            dOver120 += AmountCur;    
        }
    }

    rowBucket = tableBucket.NewRow();
    rowBucket["Current"] = dCurrent;
    rowBucket["Bucket31to60"] = dBucket31to60;
    rowBucket["Bucket61to90"] = dBucket61to90;
    rowBucket["Bucket91to120"] = dBucket91to120;
    rowBucket["Over120"] = dOver120;

    tableBucket.Rows.Add(rowBucket);

    return tableBucket;
}

以下是从 C# 创建新 AX 表的方法（这是使用扩展方法）：

public static bool CreateAXTable(this Axapta ax)
{
    string TableName = "MyCustomTable"; 
    string size = "255"; //You could load this from a setting
    bool val = false;
    if (!ax.TableExists(TableName))
    {
        AxaptaObject TablesNode = (AxaptaObject)ax.CallStaticClassMethod("TreeNode", "findNode", @"\Data Dictionary\Tables");
        AxaptaObject node;
        AxaptaObject fields;
        AxaptaObject fieldNode;

        TablesNode.Call("AOTadd", TableName); 
        node = (AxaptaObject)ax.CallStaticClassMethod("TreeNode", "findNode", "\\Data dictionary\\Tables\\" + TableName);        
        fields = (AxaptaObject)ax.CallStaticClassMethod("TreeNode", "findNode", "\\Data dictionary\\Tables\\" + TableName + "\\Fields");

        fields.Call("addString", "String1"); //add a string field
        fieldNode = (AxaptaObject)fields.Call("AOTfindChild", "String1"); //grab a reference to the field
        fieldNode.Call("AOTsetProperty", "StringSize", size);
        fieldNode.Call("AOTsave");

        fields.Call("addString", "String2"); //add a string field
        fieldNode = (AxaptaObject)fields.Call("AOTfindChild", "String2"); //grab a reference to the field
        fieldNode.Call("AOTsetProperty", "StringSize", size);
        fieldNode.Call("AOTsave");

        fields.Call("addString", "String3"); //add a string field
        fieldNode = (AxaptaObject)fields.Call("AOTfindChild", "String3"); //grab a reference to the field
        fieldNode.Call("AOTsetProperty", "StringSize", size);
        fieldNode.Call("AOTsave");

        fields.Call("addString", "String4"); //add a string field
        fieldNode = (AxaptaObject)fields.Call("AOTfindChild", "String4"); //grab a reference to the field
        fieldNode.Call("AOTsetProperty", "StringSize", size);
        fieldNode.Call("AOTsave");

        fields.Call("addReal", "Real1");
        fields.Call("addReal", "Real2");
        fields.Call("addReal", "Real3");
        fields.Call("addReal", "Real4");

        fields.Call("addDate", "Date1");
        fields.Call("addDate", "Date2");
        fields.Call("addDate", "Date3");
        fields.Call("addDate", "Date4");

        fields.Call("AOTsave");
        node.Call("AOTsave");

        AxaptaObject appl = ax.GetObject("appl");
        appl.Call("dbSynchronize", Convert.ToInt32(node.Call("applObjectId")), false);

        val = true;
    }
    else //Table already exists
    {
        val = true;
    }
    return val;
}


public static bool TableExists(this Axapta ax, string tableName)
{
    return ((int)ax.CallStaticClassMethod("Global", "tableName2Id", tableName) > 0);
}

Answer 3

下面是在 C# 中运行查询的示例：（

注意：这是使用现有查询定义的非常简单的方法，您还可以使用 QueryBuildDataSource 对象等从头开始构建查询...）

    Axapta ax = new Axapta();
    ax.Logon("", "", "", "");

    //Create a query object based on the customer group query in the AOT
    AxaptaObject query = ax.CreateAxaptaObject("Query", "CustGroupSRS");

    //Create a queryrun object based on the query to fecth records
    AxaptaObject queryRun = ax.CreateAxaptaObject("QueryRun", query);

    AxaptaRecord CustGroup = null;
    ;
    while (Convert.ToBoolean(queryRun.Call("next")))
    {
        //GetTableId function is defined here: .Net Business Connector Kernel Functions
        CustGroup = (AxaptaRecord)queryRun.Call("get", ax.GetTableId("CustGroup"));
        System.Diagnostics.Debug.WriteLine(CustGroup.get_Field("Name").ToString());
    }
    CustGroup.Dispose();
    queryRun.Dispose();
    query.Dispose();

    ax.Logoff();
    ax.Dispose();

Answer 4

老实说，我认为不可能使用业务连接器创建新表。它必须在 AX 和 AOT 内完成。

至于返回混合数据，我可能会使用容器对象。容器可以容纳子容器或 axapta 记录。 AxaptaRecord 包含来自一个已定义表的数据。
