To create new records, use INSERT statements.

INSERT Syntax

The INSERT statement specifies the columns to be inserted and the new column values. You can specify the column values in a comma-separated list in the VALUES clause, as shown in the following example:

INSERT INTO <table_name> 
( <column_reference> [ , ... ] )
VALUES 
( { <expression> | NULL } [ , ... ] ) 
  

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the rows affected, as shown in the following example:

C#

String connectionString = "OAuthClientId=myclientid;OAuthClientSecret=myclientsecret;InitiateOAuth=GETANDREFRESH;CallbackUrl=http://localhost:33333;";
using (TSheetsConnection connection = new TSheetsConnection(connectionString)) {
  int rowsAffected;
  TSheetsCommand cmd = new TSheetsCommand("INSERT INTO Timesheets (JobcodeId) VALUES ('John')", connection);
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "OAuthClientId=myclientid;OAuthClientSecret=myclientsecret;InitiateOAuth=GETANDREFRESH;CallbackUrl=http://localhost:33333;"
Using connection As New TSheetsConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New TSheetsCommand("INSERT INTO Timesheets (JobcodeId) VALUES ('John')", connection)
  rowsAffected = cmd.ExecuteNonQuery()
End Using
