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"]
);
