Synchronizing DataBase with CRM 3.0 (updating existing and creating new accounts)

I will be synchronizing existing Database with the existing CRM Accounts. I will compare the Accounts on the basis of “Name”. If the Names are same, accounts will be updated (otherwise new account will be created in the CRM system) .
I will create Console application and then schedule it for specified interval (for example , 2 hours , 4 hours ).
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Configuration;
using System.Web;
using System.Data.SqlClient;
using UpdateCRMhourlybasis.crm;
namespace UpdateCRMhourlybasis

class Program

static void Main(string[] args)

// Navn 1 and Navn will use for comparison purpose .

string navn1; // This will be the name of Account from CRM
string navn; // This will be the name of Account from Database

CrmService service = new CrmService();
service.Credentials System.Net.CredentialCache.DefaultCredentials;

// Connection to the database and retrieving “Accounts” column in .

SqlConnection con = new SqlConnection(@”Data Source=NP-1;Initial
Catalog=Emailing;Integrated Security=True”);

SqlDataAdapter thisAdapter = new SqlDataAdapter(“SELECT * FROM Accounts”, con);
DataSet thisDataSet = new DataSet();
thisAdapter.Fill(thisDataSet, “Accounts”);

foreach (DataRow theRow in thisDataSet.Tables[“Accounts”].Rows)
// I will be using few fields for update
// Now , i will make query to retrieve accounts with the specified fields, i wish to //update.

QueryExpression query = new QueryExpression();
query.EntityName = “account”;
ColumnSet columns = new ColumnSet();

// columns to retrieve
columns.Attributes = new string[] { “accountid”, “address1_city”,
“address1_country”, “address1_fax”, “address1_line1”, “name” };
query.ColumnSet = columns;
query.Criteria = new FilterExpression();
query.Criteria.FilterOperator = LogicalOperator.And;
ConditionExpression condition1 = new ConditionExpression();
condition1.AttributeName = “name”;
condition1.Operator = ConditionOperator.Equal;

// This query will retrieve the accounts from CRM, where “name” equals the name //in
//database —-AccountName

condition1.Values = new object[] { (theRow[“AccountName”].ToString()) };

query.Criteria.Conditions = new ConditionExpression[] { condition1 };
BusinessEntityCollection ret = service.RetrieveMultiple(query);

// as mentioned , “Navn” is Name of Accounts in Database
navn = (theRow[“AccountName”].ToString());

string city = (theRow[“City”].ToString());
string Emailing = (theRow[“Email”].ToString());
string Country = (theRow[“Country”].ToString());

for (int i = 0; i < ret.BusinessEntities.Length; i++)
//Retrieving all accounts , where name of Accounts in database equal the name in //CRM.
account aba1 = (account)ret.BusinessEntities[i]; = (theRow[“AccountName”].ToString());
// assiging the name of accounts (from CRM) to Navn1
navn1 =;

aba1.address1_city = (theRow[“City”].ToString());
aba1.address1_country = (theRow[“Country”].ToString());
aba1.address1_line1 = (theRow[“Address”].ToString());

aba1.address1_postalcode = (theRow[“PostalCode”].ToString());


// This part will create new accounts , if names in database do not match //with the name in CRM

if(navn !=navn1)

account k = new account(); = navn;
k.address1_city = city;
k.address1_country = Country;
k.emailaddress1 = Emailing;


catch (System.Web.Services.Protocols.SoapException ex)

    Congratulation with you Blog.
    Sync can ber tricky you now that, but dont think is good idea sync 2 3 or 4 hours, thats is not operational, if a list of vendours need to have in time info, that lag of 2 or 4 hours can be disastours, not have the oportunities correct or duplication of info.i have this issues when i make sync with CRM with others ERP. Other problems is if the network fail, or one of the 2 system fails, whats now… how to recover from failed systems, other issues, triggers (update/delete/insert) and can continue all night :P, but like what i see continue with the effort, if you want to share and you want me to help you with something can e-mail me, is in my blog.

    Good Luck and merry christmas.
