Insert multiple rows in DB2Command.ExecuteNonQuery

Question

I am trying to insert multiple rows into a DB2 database using C # code as follows:

string query = 
"INSERT INTO TESTDB2.RG_Table (V,E,L,N,Q,B,S,P) values" +
"('abc', 'def', '2009-03-27 12:01:19', 'ghi', 'jkl', NULL, NULL, NULL)," +
"('abc', 'def', '2009-03-27 12:01:19', 'ghi', 'jkl', NULL, NULL, NULL)";

DB2Command cmd = new DB2Command(query, this.connection, this.transaction);

cmd.ExecuteNonQuery();

If I stop building the query string after the first set of values, it runs without error. Attempting to load multiple values ​​using this method results in the following error:

Upload error : ERROR [42601] [IBM][DB2] SQL0104N  
An unexpected token "," was found following "".  
Expected tokens may include:  "<END-OF-STATEMENT>".  SQLSTATE=42601

The SQL syntax matches what I read elsewhere , and an example is provided in the IBM documentation:

cmd = conn.CreateCommand();
cmd.Transaction = trans;

cmd.CommandText =
"INSERT INTO company_a VALUES(5275, 'Sanders', 20, 'Mgr', 15, 18357.50), " +
"(5265, 'Pernal', 20, 'Sales', NULL, 18171.25), " +
"(5791, 'O''Brien', 38, 'Sales', 9, 18006.00)";

cmd.ExecuteNonQuery();

Can someone explain what could explain this?
