I have this piece of code like this:
var options = new DynamoDBOperationConfig
{
ConditionalOperator = ConditionalOperatorValues.Or,
OverrideTableName = nameTable,
ConsistentRead = true
};
new QueryOperationConfig()
{
IndexName = indexName,
Filter = queryFilter,
Select = SelectValues.Count
};
result = context.FromQueryAsync<TEntity>(queryConfig, options).GetRemainingAsync().Result;
as per the documentation, it should return just the count of values that match the filter, at least, the piece of code in the SelectValues class says that
//
// Summary:
// An enumeration of all supported Select values for Query and Scan. Value of Count
// will force service to return the number of items, not the items themselves.
but result is always an empty list; how can i make the count work ?
If you are still looking for the answer, this is the solution:
new QueryOperationConfig()
{
IndexName = indexName,
Filter = queryFilter,
Select = SelectValues.Count,
ConsistentRead = true
};
var table = context.GetTargetTable<TEntity>();
var search = table.Query(queryConfig);
result = search.Count;
Having ConsistentRead set to true will cause it to give you real time updates when the table is updated.
It's not working on Document level...
You can try to do this in low level model.
int count = 0;
Dictionary<string, AttributeValue> lastKey = null;
do
{
var request = new QueryRequest
{
TableName = "tableNmae",
IndexName = "indexName",
KeyConditionExpression = "ID= :v_ID",
ExpressionAttributeValues = new Dictionary<string, AttributeValue>
{
{
":v_ID",
new AttributeValue
{
N = "1"
}
}
},
ConsistentRead = false,
Select = Select.COUNT,
ExclusiveStartKey = lastKey
};
var respone = await tableClient.QueryAsync(request);
count += respone.Count;
lastKey = respone.LastEvaluatedKey;
} while (lastKey != null && lastKey.Count != 0);
I have used linq to store data, below is the code:
var result = (dynamic)null;
var serviceData = (dynamic)null;
var userData = (dynamic)null;
/****Linq 1*****/
serviceData= dtPasscode.AsEnumerable().Select(m => new
{
ACCOUNT_ID = intAccountId,
SUB_ACC_ID = m.Field<string>("ACCOUNT_ID_ALIAS")
});
/**Linq 2**/
userData = DisplyCustomerDetails(Convert.ToInt64(strSubAccountID));
result = serviceData.Concat(userData);
And another linq through function:
/**Function**/
System.Data.EnumerableRowCollection DisplyCustomerDetails(Int64 intAccountId)
{
var result = (dynamic)null;
/** Data Display if no service avaiable **/
IAccount_BL objAccount_BL = new Account_BL();
Customer objCustomer = new Customer();
DataTable dtCustomer = null;
int intErrorCount = 0;
objCustomer.Account_Id = Convert.ToInt64(intAccountId);
dtCustomer = objAccount_BL.GetCustomerDetails(objCustomer, ref intErrorCount);
objAccount_BL = null;
objCustomer = null;
if (intErrorCount == 0)
{
if (dtCustomer != null)
{
if (dtCustomer.Rows.Count > 0)
{
result = dtCustomer.AsEnumerable().Select(m => new
{
ACCOUNT_ID = intAccountId,
SUB_ACC_ID = m.Field<string>("ACCOUNT_ID_ALIAS")
});
}
}
}
return result;
}
I wanted to join both the result of Linq1 & Linq2, I tired Concat & Union, getting below error
'System.Data.EnumerableRowCollection<<>f__AnonymousTypea>' does not contain a definition for 'Concat'
To Concat both enumerables must of the same class; you cannot use anonymous classes. Define a class that has the two fields and change the code to Select them.
Also, don't use ... = (dynamic) null; just assign the variable directly
var serviceData= dtPasscode ...
var userData = DisplyCustomerDetails ...
var result = serviceData.Concat(userData);
I need to collect data and add it to temporary table in AX 2012 R3 using X++.
This is the Query on SQL
select store, receiptid, itemid, str(qty,16,0) as Qty, str(price,16,0) as Price, str(DISCAMOUNT,16,0) DiscAmount, str(taxamount,16,0) SalesTaxAmount ,convert(date, transdate) transdate, DATAAREAID from RETAILTRANSACTIONSALESTRANS

User can input transDate, itemid and storeid
this is what form looks like

My code doesn't show any error in short period but because receiptId is stored in str,
receiptId2 = strFmt('%1 || (%3.receiptId == "%2") ',receiptId2, queryValue(rcptid_txt),qbdsRetailTransactionSalesTrans.name());
there is limitation and show error for long periode
Can someone make my code more efficient and
is there any way to create Query in x++ that have same function like "IN" on SQL
You have two options:
You can use more than one query range for the same field; it will automatically count as an or
for (i = conLen(items); i > 0; i--)
qbdsRetailTransactionSalesTrans.addRange(fieldNum(RetailTransactionSalesTrans, itemId)).value(queryValue(conPeek(items,i)));
You may need special handling, if the container is empty!
Often it is better to use an (exists) join instead
ds = qbdsRetailTransactionSalesTrans.addDatasource(tableNum(RetailTransactionPaymentTrans));
ds.joinMode(JoinMode::ExistsJoin);
ds.relations(true); // Or do ds.addLink(...) etc.
I am not sure I follow the correct logic here :)
If you need to do crosscompany selections, do so using the interface for that:
qbdsRetailTransactionSalesTrans.allowCrossCompany(true);
qbdsRetailTransactionSalesTrans.addCompanyRange('5740');
qbdsRetailTransactionSalesTrans.addCompanyRange('5760');
this.db.transaction(function (tx)
{
tx.executeSql('SELECT tsk.*, cont.firstName, cont.lastName ,cont1.firstName, cont1.lastName, list.listId FROM tbl_tasks tsk, tbl_contacts cont,tbl_contactequests cont1, tbl_lists list WHERE (tsk.assignedId=0 or tsk.assignedId=cont.contactId or tsk.assignedId=cont1.contactRequestId) and tsk.taskCategoryType != "INBOX_NOT_ACCEPTED" and list.listId=tsk.listId and list.listId='+window.defaultlistid+' group by tsk.taskId', [], enyo.bind(this,this.queryResponse), enyo.bind(this,this.errorHandler));//call queryResponse
}.bind(this));
Now as you can see cont.firstName (Table tbl_contacts) & cont1.firstName has (Table tbl_contactequests) has same fields first name
for (var i = 0; i < len; i++)
{
list[i] = results.rows.item(i);
fname = list[i].firstName;
lname = list[i].lastName;
fullname = fname+' '+lname;
//alert(fullname);
if(list[i].assignedId==0)
{list[i].name = '';}
else
{list[i].name=fullname;}
}
with this loop i can able to featch first value of tbl_contacts field firstname.Now suppose if i can't to access tbl_contactequests table firstname.
Use AS keyword for SQL query:
'SELECT tsk.*,
cont.firstName AS cFirstName,
cont.lastName ,
cont1.firstName AS c1FirstName,
cont1.lastName, list.listId
FROM tbl_tasks tsk, tbl_contacts cont,
tbl_contactequests cont1, tbl_lists list
WHERE (tsk.assignedId=0 OR tsk.assignedId=cont.contactId OR
tsk.assignedId=cont1.contactRequestId) AND
tsk.taskCategoryType != "INBOX_NOT_ACCEPTED" AND
list.listId=tsk.listId AND list.listId='+window.defaultlistid+'
GROUP BY tsk.taskId'
Addding data into kartlar table (RehberID,KampanyaID,BrimID) is ok. But which Kart'ID created? I need to learn which Id created after adding data (RehberID,KampanyaID,BrimID) into Kartlar?
public static List<Kartlar> SaveKartlar(int RehberID, int KampanyaID, int BrimID, string Notlar)
{
using (GenSatisModuleEntities genSatisCtx = new GenSatisModuleEntities())
{
Kartlar kartlar = new Kartlar();
kartlar.RehberReference.EntityKey = new System.Data.EntityKey("GenSatisModuleEntities.Rehber", "ID", RehberID);
kartlar.KampanyaReference.EntityKey = new System.Data.EntityKey("GenSatisModuleEntities.Kampanya", "ID", KampanyaID);
kartlar.BirimReference.EntityKey = new System.Data.EntityKey("GenSatisModuleEntities.Birim", "ID", BrimID);
kartlar.Notlar = Notlar;
genSatisCtx.AddToKartlar(kartlar);
genSatisCtx.SaveChanges();
List<Kartlar> kartAddedPatient;
kartAddedPatient = (from k in genSatisCtx.Kartlar
where k.RehberReference.EntityKey == RehberID &&
k.KampanyaReference.EntityKey == KampanyaID &&
k.BirimReference.EntityKey == BrimID
select k)
return kartAddedPatient ;
}
}
How can I do that? I want to get data from Kartlar which data I added?
Upon you call ObjectContext.SaveChanges the generated ID will be in "kartlar" object:
using (GenSatisModuleEntities genSatisCtx = new GenSatisModuleEntities())
{
Kartlar kartlar = new Kartlar();
//Do your stuff with kartlar...
genSatisCtx.AddToKartlar(kartlar);
genSatisCtx.SaveChanges();
//kartlar.ID - the generated identifier should be loaded into ID property
}
[updated]
List<Kartlar> kartAddedPatient;
kartAddedPatient = (from k in genSatisCtx.Kartlar
where k.Rehber.ID == RehberID &&
k.Kampanya.ID == KampanyaID &&
k.Birim.ID == BrimID
select k).ToList()
return kartAddedPatient ;
