# Paging behaviors and ordering
20+
21+
When querying data using FetchXML, paging query results can make viewing large
22+
volumes of information easier. It is important when using paging to include
23+
ordering parameters as well. Without proper ordering, paging requests for the
24+
“next 50” records can result in retrieving the same records across multiple
25+
pages making reviews and edits much more difficult. Proper page ordering
26+
requires including unique values to help identify which records are included in
27+
a page.
28+
29+
## Legacy paging
30+
31+
Legacy paging within the Common Data Service loads all the results of the query
32+
up to the current page into memory on the server, selects the number of records
33+
that are needed for the page, and then ignores the rest. This has benefits such
34+
as quick back/forward paging through the data or skipping to a specific page,
35+
but it also has restrictions such as a 50K row limit, performance issues with
36+
large complex queries, and arbitrarily sorted distinct query results.
37+
38+
## Ordering with a paging cookie
39+
40+
When paging with ordering, a cache of the previous page’s results is stored in a
41+
paging cookie. This is used to calculate what the next page of data should
42+
display.
43+
44+
If a user does not specify any “order by” parameters, the system will
45+
automatically insert “order by "\<\<entity name\>\>".\<\<entityId\>\> asc” to
46+
provide some basic ordering. Depending on the data that is being queried, this
47+
may result in inadequate and unexpected results as a single system user can be
48+
associated with multiple records within any query.
49+
50+
If distinct FetchXML queries are being used, the system will not add any
51+
additional ordering due to potential impacts to the data returned. In these
52+
cases, users will have to add at least a single ordering value for a more
53+
consistent paging experience.
54+
55+
> [!NOTE]
56+
> Paging using FetchXML for Common Data Service is dynamic. The page a
57+
> record appears on is determined at the time that each page is rendered. If 1000
58+
> records are being displayed 50 to a page, the first 50 records are displayed as
59+
> page one. When page two is requested, the system determines what the next 50
60+
> records should be at the time of request. Because of this, it would not be
61+
> possible to use the new paging functionality for back paging. Legacy behavior is
62+
> used for back paging which will have reduced performance and any returns after
63+
> page 500 cannot be “paged back” due to legacy limitations. 
64+
65+
### Why ordering is important
66+
67+
If a query is run to retrieve all records with a state of “Open” this could
68+
result in 1000 returns. When paging from page one to page two, there is no way
69+
for the system to know which orders to display on page two because all of the
70+
records have the same state. The paging of these records will not be efficient
71+
or consistent.
72+
73+
Providing an “order by” value gives the paging cookie the ability to order the
74+
data by an additional value and recognize the last record in a page based on the
75+
values provided.
76+
77+
#### Example 1
78+
79+
A query is created to get all records with a state of ‘Open’, include the status
80+
for every record, and show three records per page. The query is then ordered by
81+
status. The query result would page as shown in the following table:
82+
83+
| State | Status | Page |
84+
|-----------|------------|---------------|
85+
| Open | Active | 1 |
86+
| Open | Active | 1 |
87+
| Open | Active | End of page 1 |
88+
| Open | Active | |
89+
| Open | Active | |
90+
| Open | Inactive | |
91+
| Open | Inactive | |
92+
93+
The paging cookie will save information about the last record on the page, but
94+
when it’s time to get page two in this example, there is no unique identifier to
95+
ensure that the next page populated uses the unviewed records or include the
96+
first two records that were on page one.
97+
98+
To solve this problem, queries should include “order by” columns that have
99+
unique values. It is possible to use multiple “order by” values. Below is a
100+
better way to order data for this query:
101+
102+
#### Example 2
103+
104+
A query is created to get all records of a state of ‘Open’, any status, include
105+
the Case IDs, and show three records per page. It orders by status and by Case
106+
ID (a unique identifier) which will order in ascending order. The query result
107+
would page the results as shown below:
108+
109+
| State | Status | Case ID | Page |
110+
|-----------|------------|-------------|---------------|
111+
| Open | Active | Case-0010 | 1 |
112+
| Open | Active | Case-0021 | 1 |
113+
| Open | Active | Case-0032 | End of Page 1 |
114+
| Open | Active | Case-0034 | |
115+
| Open | Active | Case-0070 | |
116+
| Open | Inactive | Case-0015 | |
117+
| Open | Inactive | Case-0047 | |
118+
119+
The query results are first ordered by the Status, and then ordered by the Case
120+
ID in ascending order. When page two is generated, the result would be as shown
121+
below:
122+
123+
| State | Status | Case ID | Page |
124+
|-----------|------------|-------------|---------------|
125+
| Open | Active | Case-0010 | |
126+
| Open | Active | Case-0021 | |
127+
| Open | Active | Case-0032 | End of Page 1 |
128+
| Open | Active | Case-0034 | 2 |
129+
| Open | Active | Case-0070 | 2 |
130+
| Open | Inactive | Case-0015 | |
131+
| Open | Inactive | Case-0047 | |
132+
133+
When generating page two of this query set, the cookie will have Case-0032
134+
stored as the last record in the first page, so page two will pick up at the
135+
next record in the set after that record. This will allow for more consistent
136+
results.
137+
138+
### Ordering suggestions
139+
140+
Listed below are some suggestions for improving ordering of paging results, along with some areas to avoid.
141+
142+
#### Best ordering
143+
144+
- Always include a column that has a unique identifier (i.e., entity ID
145+
columns, auto-number columns, user/contact IDs)
146+
147+
#### Good ordering
148+
149+
- Include multiple fields that will most likely result in unique combinations:
150+
- First name + last name + email address
151+
- Full name + email address
152+
- Email address + company name
153+
154+
#### Poor ordering
155+
156+
- Orders that do not include unique identifiers
157+
158+
- Orders that have single or multiple fields that are not likely to provide
159+
uniqueness such as:
160+
- Status and state
161+
- Option sets or booleans
162+
- Name values by themselves (i.e., last only, first only, company name
163+
only)
164+
- Text fields like titles, descriptions, multi-line text
165+
- Non unique number fields
166+
167+
### Ordering and multiple entity queries
168+
169+
Sometimes data is needed that spans multiple entities and must be queried with a
170+
table JOIN. In these cases, ordering can be included for both entities in the
171+
query. Make sure to use at least one column with a unique ID per entity to
172+
ensure the paging provides the best results. However, the query will be
173+
downgraded to legacy paging, where no paging cookie will be returned, in these
174+
cases due to limitations of the N:1 relationship structure that could result in
175+
missing data.
