我正在编写一个 C# 命令行工具来从 AX 获取数据并将数据（创建新表）添加到 AX。
从 AX 表中获取数据很容易并在此处记录：http: //msdn.microsoft.com/en-us/library/cc197126.aspx
向现有表添加数据也很容易：http: //msdn.microsoft.com/en-us/library/aa868997.aspx
但我不知道如何做两件事：
有人可以分享一些示例代码或提供一些关于从哪里开始寻找的指示。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。
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;
}
这是一种从 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);
}
以下是在 C# 中运行查询的示例：
（注意：这是一种使用现有查询定义的非常简单的方法，您也可以使用 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();
老实说，我认为使用业务连接器创建新表是不可能的。它必须在 AX 和 AOT 内完成。
至于返回混合数据，我可能会为此使用容器对象。容器可以容纳子容器或 axaptarecords。AxaptaRecord 包含来自一个已定义表的数据。
