How do I get values read values line a DataReader to read values of fields returned by multi in the following code to set the values in the Class
OracleRefCursor m_Cursor=null;
Dapper.SqlMapper.GridReader multi =null;
using (m_Conn = new OracleConnection(m_ConnectionString))
{
try
{
m_Conn.Open();
String m_LastName = "S" + "%";
String m_Id = "";
String m_EmpId = "";
var p = new OracleDynamicParameters();
p.Add(":p_LastName", m_LastName);
p.Add(":p_Id", m_Id);
p.Add(":p_EmpId", m_EmpId);
p.Add( ":p_Cursor1", dbType: OracleDbType.RefCursor, direction: ParameterDirection.Output );
using (multi = m_Conn.QueryMultiple(m_ProcedureName, param: p, commandType: CommandType.StoredProcedure))
{
}
}
catch (Exception ex)
{
String m_Error = ex.ToString();
}
}//end of using statement
From Dapper docs:
var sql =
#"
select * from Customers where CustomerId = #id
select * from Orders where CustomerId = #id
select * from Returns where CustomerId = #id";
using (var multi = connection.QueryMultiple(sql, new {id=selectedId}))
{
var customer = multi.Read<Customer>().Single();
var orders = multi.Read<Order>().ToList();
var returns = multi.Read<Return>().ToList();
...
}

Im trying to update rows in my table using loop, I get no error but nothing changed in my data...Thats my code.. What am I missing ?
private void updateZipInDB(List<ZipObj> zipCodeToUpdate)
{
var comm = "";
string DbConnString = ConfigurationManager.AppSettings["dbConnectionString"].ToString();
using (SqlConnection conn = new SqlConnection(DbConnString))
{
comm = "UPDATE Account SET address1_postalcode = #newVal WHERE AccountId = #accountID";
using (SqlCommand command = new SqlCommand(comm, conn))
{
conn.Open();
command.Parameters.AddWithValue("#newVal", "f");
command.Parameters.AddWithValue("#accountID", "f");
for (int i = 0; i < zipCodeToUpdate.Count; i++)
{
zipCodeToUpdate[i].NewVal + "' WHERE AccountId = '" + zipCodeToUpdate[i].AccountId + "'";
command.Parameters["#newVal"].Value = zipCodeToUpdate[i].NewVal;
command.Parameters["#accountID"].Value = zipCodeToUpdate[i].AccountId;
command.ExecuteNonQuery();
}
conn.Close();
}
}
}
I need to make a generic logger to record certain insert/update statements so that my testers can verify the data being inserted is correct.
My first thought was that I would just use a function that accepted DynamicParameters and I would foreach through the DynamicParameters to generate a string to list the parameter's name and value and make them easier to read for the testers.
Unfortunately, Dapper.DynamicParameters does not contain a public definition for "GetEnumerator"
Here is basic example of what I was hoping to do:
string myFormattedListofParameters = "";
foreach (var p in myDynamicParameters)
{
myFormattedListofParameters += p.Name + "=" + p.Value.ToString();
}
Try:
var sb = new StringBuilder();
foreach (var name in p.ParameterNames)
{
var pValue = p.Get<dynamic>(name);
sb.AppendFormat("{0}={1}\n", name, pValue.ToString());
}
string ParametersToString(DynamicParameters parameters)
{
var result = new StringBuilder();
if (parameters != null)
{
var firstParam = true;
var parametersLookup = (SqlMapper.IParameterLookup)parameters;
foreach (var paramName in parameters.ParameterNames)
{
if (!firstParam)
{
result.Append(", ");
}
firstParam = false;
result.Append('#');
result.Append(paramName);
result.Append(" = ");
try
{
var value = parametersLookup[paramName];// parameters.Get<dynamic>(paramName);
result.Append((value != null) ? value.ToString() : "{null}");
}
catch
{
result.Append("unknown");
}
}
}
return result.ToString();
}
One line with Linq:
string.Join(", ", from pn in sprocParams.ParameterNames select string.Format("#{0}={1}", pn, (sprocParams as SqlMapper.IParameterLookup)[pn]))
I'm using that to log with log4net:
Log.InfoFormat("Exec {0} {1}", storedProc, string.Join(", ", from pn in sprocParams.ParameterNames select string.Format("#{0}={1}", pn, (sprocParams as SqlMapper.IParameterLookup)[pn])));
Just in case,
var pmaster = new Dapper.DynamicParameters();
SortedList l = new SortedList();
l.Add("param1", object1);
l.Add("param2", object2);
l.Add("param3", object3);
l.Add("param4", object4);
foreach(var key in l.Keys)
{
var val = l[key];
pmaster.Add(key.ToString(), val);
}
Worked for me.
My query returns account.name, account.account and account.parentaccountid.
I'm using Silverlight and CRM2011.
Now I'm having trouble to find out how to extract value from parentaccountid attribute.
I have silverlightextensionmethods.cs file included in my VS project, and I'm using GetAttributeValue<Guid>("parentaccountid") to get the value from parentaccountid.
The value returned is empty.
Has anyone any ideas how to accomplish this?
I can get any other attribute value, but parentaccountid in account and parentcustomerid in contact are making my life very difficult.
Code:
FIRST I CREATE QUERYEXPRESSION:
string temp="name;accountid;parentaccountid";
string[] fields = temp.Split(';');
QueryExpression query = new QueryExpression()
{
EntityName = entity,
ColumnSet = new ColumnSet { Columns = new System.Collections.ObjectModel.ObservableCollection<string>(fields) },
Criteria = new FilterExpression
{
FilterOperator = LogicalOperator.And,
Conditions =
{
new ConditionExpression
{
AttributeName = parentidfield,
Operator = ConditionOperator.Equal,
Values = { id }
}
}
}
};
OrganizationRequest req = new OrganizationRequest();
req.RequestName = "RetrieveMultiple";
req["Query"] = query;
service.BeginExecute(req, new AsyncCallback(GetChildren_ExecuteCallBack), service);
NEXT I TY TO READ VALUES FORM RESPONSE
void GetChildren_ExecuteCallBack(IAsyncResult childresult)
{
List<TreeRecord> listc = new List<TreeRecord>();
try
{
OrganizationResponse childresponse = ((IOrganizationService)childresult.AsyncState).EndExecute(childresult);
EntityCollection childresults = (EntityCollection)childresponse["EntityCollection"];
if (childresults.Entities.Count > 0)
{
TreeConfig sitm = new TreeConfig();
string sdisplay = "";
string[] fields = "".Split(';');
string sid = "";
string pid = "";
foreach (Entity childentity in childresults.Entities)
{
foreach (TreeConfig sitem in Configs)
{
if (sitem.EntityName == childentity.LogicalName)
{
sitm = sitem;
}
}
TreeRecord childitem = new TreeRecord();
string sValue = "";
sdisplay = "name;accountid;parentaccountid";
fields = sdisplay.Split(';');
sid = "accountid";
pid = "parentaccountid";
int i = sdisplay.Split(';').Length;
for (int j = 0; j < i; j++)
{
try { sValue += childentity.GetAttributeValue<string>(fields[j]) + " "; }
catch (Exception ex)
{
//s = "sValue haku: " + ex.Message.ToString();
//this.ReportMessage(s.ToString());
}
}
childitem.Name = sValue;
childitem.EntityName = childentity.LogicalName;
childitem.Level = sitm.Level;
childitem.ParentEntityName = sitm.EntityName;
childitem.Color = sitm.Color;
childitem.RecordId = childentity.GetEntityId<Guid>(sid);
try { childitem.ParentId = childentity.GetAttributeValue<Guid>(pid); }
catch
{
//sb.AppendLine("guid: parentid tietoa ei löydy");
//this.ReportMessage(sb.ToString());
}
listc.Add(childitem);
}
}
}
Instead of
childentity.GetAttributeValue<Guid>(pid)
use
childentity.GetAttributeValue<EntityReference>(pid)
my scenario:
helper = new OracleHelper();
helper.CreateAndOpenConnection();
//cmd = new OracleCommand("PCK_JOBS.ARRAY_INSERT", helper.OracleHelperConnection);
cmd = new OracleCommand("PCK_JOBS.SCALAR_INSERT", helper.OracleHelperConnection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.BindByName = true;
cmd.ArrayBindCount = 3;
var paramNames = new OracleParameter();
paramNames.ParameterName = "P_JOB_TITLE";
paramNames.Size = 3;
paramNames.OracleDbType = OracleDbType.Varchar2;
paramNames.Value = new string[3] { "1", "2", "3" };
cmd.Parameters.Add(paramNames);
paramNames = new OracleParameter();
paramNames.ParameterName = "O_JOB_ID";
paramNames.Size = 3;
paramNames.Direction = ParameterDirection.Output;
paramNames.OracleDbType = OracleDbType.Int32;
paramNames.Value = new int[3] { 0, 0, 0 };
cmd.Parameters.Add(paramNames);
try
{
cmd.ExecuteNonQuery();
}
catch (Exception exc)
{
}
var outParams = cmd.Parameters[1];
when PL-SQL procedure fails for example inserting row 2, and consequently ExecuteNonQuery catch, my output parameters (outParams) are all set to 0 (init value), also for rows correctly processed by procedure.
Is there a way to handle correctly this? so having the partial OUT array parameters correctly filled?
This is what I was referring to in the other thread; handle the exception in the pl/sql:
create or replace
PROCEDURE TESTDATA(myArrayNo in number , myOutputArray out varchar2)
is
customException EXCEPTION;
PRAGMA EXCEPTION_INIT( customException, - 20101 );
begin
myOutputArray := chr( myArrayNo );
if mod( myArrayNo, 2 ) = 0 then
raise customException;
end if;
exception
when customException then
myOutputArray := 'I am invalid';
end TESTDATA;
but only capture expected errors here, ones that you don't want to stop the progression, if you put in a when others... then things may get hairy and hide bugs and allow bulk updates/inserts that you don't want to allow.
c# code:
...
int[] myArrayNo = new int[3]{65, 66, 67};
String[] myOutputArray ;
OracleConnection connection = new OracleConnection(connectStr);
OracleCommand command = new OracleCommand (
"TESTDATA", connection);
//insert into dept values (:deptno, :deptname, :loc)
// Set the Array Size to 3. This applied to all the parameter in
// associated with this command
command.ArrayBindCount = 3;
command.CommandType = CommandType.StoredProcedure ;
command.BindByName = true;
// deptno parameter
OracleParameter arrayNoParam = new OracleParameter("myArrayNo",OracleDbType.Int32);
arrayNoParam.Direction = ParameterDirection.Input;
arrayNoParam.Value = myArrayNo;
command.Parameters.Add(arrayNoParam);
OracleParameter arrayOutParam = new OracleParameter();
arrayOutParam.ParameterName = "myOutputArray" ;
arrayOutParam.Direction = ParameterDirection.Output ;
arrayOutParam.ArrayBindSize = new int[3] { 50, 50, 50 };
arrayOutParam.OracleDbTypeEx = OracleDbType.Varchar2 ;
command.Parameters.Add(arrayOutParam);
try
{
connection.Open();
command.ExecuteNonQuery();
myOutputArray = (String[])command.Parameters["myOutputArray"].Value ;
for (int i = 0; i < 3; i++){
Console.WriteLine("myOutputArray{0} = {1}",
i, myOutputArray[i]);
}
}
catch (OracleException e)
{
Console.WriteLine("OracleException {0} occured", e.Message);
if (e.Number == 24381)
for (int i = 0; i < e.Errors.Count; i++){
Console.WriteLine("Array Bind Error {0} occured at Row Number {1}",
e.Errors[i].Message, e.Errors[i].ArrayBindIndex);
}
}
and outputs
myOutputArray0 = A
myOutputArray1 = I am invalid
myOutputArray2 = C
You can also use this
cmd.ArrayBindCount = length;
Oracle.DataAccess.Client.OracleParameter P_FinVslCd = new Oracle.DataAccess.Client.OracleParameter("ic_fin_vsl_code", Oracle.DataAccess.Client.OracleDbType.Varchar2);
P_FinVslCd.Direction = ParameterDirection.Input;
P_FinVslCd.Value = ArrFinVslCd;
cmd.Parameters.Add(P_FinVslCd);
This is my method :-
[Invoke]
public List<FamilyEvent> GetFamilyEvents(int userId)
{
List<FamilyEvent> familyEvents = new List<FamilyEvent>();
int id = -1; //just to fool ria
//this is for birthday reminders.
var qry = ((from member in this.ObjectContext.TreeMembers.Where(m => m.UserId == userId && m.Birthdate == null)
select member.TreeMemberId).Except(from item in this.ObjectContext.FamilyEvents where item.ReminderType ==
FMT.Data.Web.Helpers.Global.FAMILY_EVENTS_REMINDERS.BIRTHDAY_REMINDER
select item.TreeMemberId));
var mainQry = from mainMember in this.ObjectContext.TreeMembers
where qry.Contains(mainMember.TreeMemberId)
select mainMember;
foreach (var item in mainQry)
{
FamilyEvent familyEvent = new FamilyEvent
{
FamilyEventId = id--,
TreeMemberId = item.TreeMemberId,
RelatedTreeMemberId = -1,
ReminderType = FMT.Data.Web.Helpers.Global.FAMILY_EVENTS_REMINDERS.BIRTHDAY_REMINDER
};
familyEvent.TreeMember = item;
familyEvents.Add(familyEvent);
}
//this is for anniversary events
qry = ((from member in this.ObjectContext.TreeMembers.Where(m => m.UserId == userId && m.RelationId == (short)Relations.Partner)
select member.TreeMemberId).Except(from item in this.ObjectContext.FamilyEvents where item.ReminderType == FMT.Data.Web.Helpers.Global.FAMILY_EVENTS_REMINDERS.ANNIVERSARY_REMINDER
select item.TreeMemberId));
mainQry = from mainMember in this.ObjectContext.TreeMembers.Include("RelatedTreeMember")
where qry.Contains(mainMember.TreeMemberId)
select mainMember;
foreach (var item in mainQry)
{
FamilyEvent familyEvent = new FamilyEvent
{
TreeMemberId = item.TreeMemberId,
TreeMember = item,
RelatedTreeMemberId = item.RelatedTreeMemberId,
ReminderType = FMT.Data.Web.Helpers.Global.FAMILY_EVENTS_REMINDERS.ANNIVERSARY_REMINDER
};
familyEvent.RelatedTreeMember = item.RelatedTreeMember;
familyEvents.Add(familyEvent);
}
return familyEvents;
}
As you can see i programmatically populate the entities and populate it. When i put breakpoint on return familyEvents, i can see the correct data. However on client side, the TreeMember and RelatedTreeMember value become null. Why is it so? If i do not use [Invoke] and instead use [Query] it works, but i need Invoke in my case.
