Calling Stored Procedures
You can invoke a stored procedure using ServiceNowCommand in the same way as any other SQL stored procedure. To instantiate a ServiceNowCommand object, provide the name of the stored procedure and a ServiceNowConnection instance as arguments to the constructor. Set the value of the CommandType property to "StoredProcedure" and add the parameters as key-value pairs to the Parameters collection of the ServiceNowCommand instance.
C#
string connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;"; using (ServiceNowConnection connection = new ServiceNowConnection(connectionString)) { ServiceNowCommand cmd = new ServiceNowCommand("RefreshOAuthAccessToken", connection); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new ServiceNowParameter("@OAuthAccessToken", "OAuthAccessToken")); // Add other parameters as needed ... ServiceNowDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { for (int i = 0; i < rdr.FieldCount; i++) { Console.WriteLine(rdr.GetName(i) + " --> " + rdr[i]); } Console.WriteLine(); } }
VB.NET
Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;" Using connection As New ServiceNowConnection(connectionString) Dim cmd As New ServiceNowCommand("RefreshOAuthAccessToken", connection) cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add(New ServiceNowParameter("@OAuthAccessToken", "OAuthAccessToken")) ' Add other parameters as needed ... Dim rdr As ServiceNowDataReader = cmd.ExecuteReader() While rdr.Read() For i As Integer = 0 To rdr.FieldCount - 1 Console.WriteLine(rdr.GetName(i) + " --> " + rdr(i)) Next Console.WriteLine() End While End Using
Alternatively, you can set the parameters of a stored procedure in the text of the command. The support for stored procedure statements follows the standard form shown below:
"EXECUTE my_proc @first = 1, @second = 2, @third = 3;" "EXEC my_proc @first = 1, @second = 2, @third = 3;"
To execute a parameterized query, add parameters as key-value pairs to the Parameters collection of the ServiceNowCommand instance.
C#
string connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;"; using (ServiceNowConnection connection = new ServiceNowConnection(connectionString)) { ServiceNowCommand cmd = new ServiceNowCommand("EXECUTE RefreshOAuthAccessToken OAuthAccessToken = @OAuthAccessToken;", connection); cmd.Parameters.Add(new ServiceNowParameter("@OAuthAccessToken", "OAuthAccessToken")); // Add other parameters as needed ... ServiceNowDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { for (int i = 0; i < rdr.FieldCount; i++) { Console.WriteLine(rdr.GetName(i) + " --> " + rdr[i]); } Console.WriteLine(); } }
VB.NET
Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;User=MyUser;Password=MyPassword;Url=https://MyInstance12345.service-now.com/;" Using connection As New ServiceNowConnection(connectionString) Dim cmd As New ServiceNowCommand("EXECUTE RefreshOAuthAccessToken OAuthAccessToken = @OAuthAccessToken;", connection) cmd.Parameters.Add(New ServiceNowParameter("@OAuthAccessToken", "OAuthAccessToken")) ' Add other parameters as needed ... Dim rdr As ServiceNowDataReader = cmd.ExecuteReader() While rdr.Read() For i As Integer = 0 To rdr.FieldCount - 1 Console.WriteLine(rdr.GetName(i) + " --> " + rdr(i)) Next Console.WriteLine() End While End Using
