Microsoft CRM – Client Relationship Management package from Microsoft Business Solutions was initially designed to be customizable with Microsoft Visual Studio.Net and one of its programming languages – C#.Net or VB.Net. You can use ADO.Net, Web Service, Transact SQL scripting and stored procedures, deploy such SQL Server tools as Linked Server to all ODBC/OLEDB compliant database, including ORACLE, Sybase, Ingress, DB2, Unidata, Pervasive SQL, Ctree and even Lotus Notes/Domino. In this small article we would like to give you the clue on programming the integration with SQL third party Database.

First – use Microsoft CRM SDK to initiate communication with Microsoft CRM, we have it in C#:

String[] arr1 = coll.AllKeys;
int loop1, loop2;
for (loop1 = 0; loop1 0?1:arr1.Length); loop1++) 
{
	String[] arr2 = coll.GetValues(arr1[loop1]);
	for (loop2 = 0; loop2 < arr2.Length; loop2++) 
	{
		strAccountId =  arr2[loop2].Replace("}",null);
		strAccountId = strAccountId.Replace("{",null);
	}
}

if (Page.IsPostBack==false)
{
	// Server should be set with the name of the platform Web server
	string Server = ConfigurationSettings.AppSettings["ServerName"];

	// VirtualDirectory should be set with the name of the Microsoft 
	// CRM Virtual Directory on the platform Web server
	string VirtualDirectory = "mscrmservices";
	string strDir = "http://" + Server + "/" + VirtualDirectory + "/";

	// BizUser proxy object
	Microsoft.CRM.Proxy.BizUser oBizUser = new Microsoft.CRM.Proxy.BizUser ();
	oBizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
	oBizUser.Url = strDir + "BizUser.srf";

	// CRMAccount proxy object
	Microsoft.CRM.Proxy.CRMAccount account = new Microsoft.CRM.Proxy.CRMAccount ();
	account.Credentials = System.Net.CredentialCache.DefaultCredentials;
	account.Url = strDir + "CRMAccount.srf";

Then you use ADO.Net for calling stored procedure with parameters to do the integration job:

try
{
	string SQLStatement="ICS_UpdateAccountPrivate '"+
		strAccountId +"' , '" + this.TextBoxWorkPerformed.Text +
		"' , "+doubleEncode(System.Double.Parse(this.TextBoxAnnualRevenue.Text))+" , "+
		intEncode(System.Int32.Parse(this.TextBoxNumberOfEmployees.Text.Replace(",","")))+" , "+
		doubleEncode(System.Double.Parse(this.TextBoxAverageGrowthRate.Text))+" , "+
		"'"+this.DropDownListOwnership.SelectedItem.Text +"' , "+
		intEncode(System.Int32.Parse(this.RadioButtonList.SelectedItem.Value))+" , "+
		intEncode(System.Int32.Parse(this.TextBoxCredit.Text.Replace(",","")))+" , '"+
		this.TextBoxComments.Text+"'";

	System.Data.SqlClient.SqlConnection tmpConnection =
		new System.Data.SqlClient.SqlConnection(ConfigurationSettings.AppSettings["ConnectionStringICS"]
		);
