INSERT with query in string Entity Framework

This is trying to give an insert in the table using a string containing a sql code ... when I use the DELETE command it runs perfectly now when I squeeze the insert no ... the insert runs straight into the database. Follow the code:

public void Inserir(AjusteAdministrativoPorFilial ajusteAdministrativo, string id_user)
        {/* alterar */
            try
            {
                ValidarAjusteAdministrativoPorFilial(ajusteAdministrativo);

                string strFiliais = "";

                for(int i=0; i<ajusteAdministrativo.AjusteAdministrativoPorFilialFiliais.Count; i++)
                {
                    strFiliais += ajusteAdministrativo.AjusteAdministrativoPorFilialFiliais[i].CodigoFilial.ToString() + ',';
                }
                strFiliais = strFiliais.Substring(0, strFiliais.Length-1);


                string sqlQuery = String.Format(@"
                                  INSERT INTO MAG_T_AJUSTE_USUARIO_LOG 
                                    (ID_AJUSTE_USUARIO_LOG, 
                                     ID_USER,
                                     FILIAIS,
                                     DATA)
                                  SELECT
                                      10 AS ID_AJUSTE_USUARIO_LOG, 
                                     '{0}' AS ID_USER, 
                                     '{1}' AS FILIAIS, 
                                     '16/02/2018 17:54:21' AS DATA 
                                  FROM DUAL;
                                  ", id_user, strFiliais);


                //Repositorio.Query(sqlQuery);
                Repositorio.test(sqlQuery);

                //Repositorio.Database.ExecuteSqlCommand(sqlQuery.ToString());

                Repositorio.Commit();
            }
            catch (Exception ex)
            {
                Repositorio.RollBack();
                throw ex;
            }
        }
    }
