This topic describes a common set of operations implemented by each sample in this group. This topic describes the HTTP requests and responses and text output that each sample in this group will perform without the language specific details. See the language specific descriptions and the individual samples for details about how this operations are performed.

Demonstrates

This sample is divided into the following principal sections, containing Web API query data operations which are discussed in greater detail in the associated conceptual topics.

Topic section	Associated topic(s)
Section 1: Select specific properties	Retrieve specific properties Formatted values
Section 2: Use query functions	Filter rows Use OData query functions Compose a query with functions Web API Query Function Reference
Section 3: Ordering and aliases	Order rows Filter rows

Section 10: Delete sample records	Basic delete Execute batch operations using the Web API

The following sections contain a brief discussion of the Dataverse Web API operations performed, along with the corresponding HTTP messages and associated console output.

Section 0: Create records to query

The sample code creates a set of sample rows to query. The code deletes the data at the end unless you choose to keep it. You may get different results depending on existing data in your environment.

The data is added using deep insert in a single POST request and matches the following structure:

Section 1: Select specific properties

Always include the $select query option in your queries. If you don't, the server returns all properties of each table row, which reduces performance. Learn how to select columns.

This example demonstrates how to construct a basic query by selecting three properties of a contact EntityType. The properties are fullname, jobtitle, annualincome. The section also illustrates the differences between formatted and unformatted values as seen in the results of the contact's annualincome property.

In this example, we are requesting for a specific contact. In this case, it's the primary contact of the account, Yvonne McKay (sample).

Request:

GET [Organization Uri]/api/data/v9.2/contacts(81716234-9628-ed11-9db1-000d3a320482)?$select=fullname,jobtitle,annualincome HTTP/1.1

  "jobtitle": "Coffee Master",
  "annualincome@OData.Community.Display.V1.FormattedValue": "$45,000.00",
  "annualincome": 45000.0,
  "_transactioncurrencyid_value@OData.Community.Display.V1.FormattedValue": "US Dollar",

  "contactid": "81716234-9628-ed11-9db1-000d3a320482"
}

Console output:

Contact basic info:
        Fullname: Yvonne McKay (sample)
        Jobtitle: Coffee Master
        Annualincome (unformatted): 45000
        Annualincome (formatted): $45,000.00

Section 2: Use query functions

Use filter options to set criteria for the results you want. You can build simple to complex filters using a combination of query functions, comparison operators, and logical operators. More information: Filter rows

Query functions are functions you can use as a filter criteria in a query. These functions accept parameters and return a Boolean value.There are standard query functions and Dataverse specific query functions. This sample illustrates how to create a query for each type.

Standard query functions

Dataverse supports a subset of OData built-in query functions, specifically: contains, endswith, and startswith. For example, the contains standard query function allows you to filter for properties that match a string. More information: Use OData query functions

In this operation, we are querying for all contacts with fullname containing the string (sample).

Request:

GET [Organization Uri]/api/data/v9.2/contacts?$select=fullname,jobtitle,annualincome&$filter=contains(fullname,'(sample)') and _parentcustomerid_value eq 7d716234-9628-ed11-9db1-000d3a320482 HTTP/1.1

Dataverse query functions

Dataverse query functions provide a number of options to build queries that are relevant for Dataverse. For a complete list of these functions, refer to the Web API Query Function Reference. More information: Compose a query with functions

YDataverse query functions are similar to the standard query functions. The main difference is that when you use Dataverse query functions, you must provide the full name of the function, including the parameter name(s). For example, to get a list of contacts created in the last hour, you can build a query using the LastXHours function.

Request:

Set precedence

Since all operators have the same precedence, use parentheses to establish the order in which query conditions are evaluated. Filters are applied from left to right. The order in which statements appear in the filter can affect the results.

In this example, we're requesting a list of all contacts where fullname contains (sample), jobtitle contains either senior or manager, and annualincome is greater than 55000. To get the results we want, we must use parentheses to group the jobtitle filters. If we don't, the or operator has the same precedence as the and operators. The query in this example looks like this: $filter=contains(fullname,'(sample)') and (contains(jobtitle,'senior') or contains(jobtitle,'manager')) and annualincome gt 55000.

Section 3: Ordering and aliases

Order results

To sort results in ascending or descending order, use the $orderby filter option . In this example, we will query for all contacts with fullname containing (sample) and request the data in ascending order based on the jobtitle property value and then in descending order based on the annualincome property value using this syntax: $orderby=jobtitle asc, annualincome desc.

Parameter alias

Use parameter aliases to more easily reuse parameters in your filters. You can use aliases in $filter and $orderby options. If the alias isn't assigned a value, it's assumed to be null.

You can also use parameter aliases when you call functions. For example, we can rewrite the query in the previous order results operation to use parameters and get the same output.

Section 4: Limit and count results

As a best practice, don't return more data than you need. To protect performance, the server returns a maximum of 5,000 table rows per request.

To limit the number of results returned, use the $top query option or add odata.maxpagesize in the request header. The $top query option returns the top number of rows from the result set and ignores the rest. The odata.maxpagesize request header specifies the number of rows to return per page with an @odata.nextLink property to get the results of the next page. Learn more about page results.

Top results

We can apply the $top query option to limit the basic query operation to the first five contacts with fullname containing (sample). In this case, the request actually produces at least 10 results, but only the first 5 entries are returned in the response.

Result count

You can get the count of rows from a collection-valued property or a count of matched table rows in a filter. The count tells you the number of possible rows in your result. However, Dataverse returns 5,000 as the maximum count even if the result may have more.

In this example, we build a filter where jobtitle contains either Senior or Manager and we also request a $count of the result. The response contains the count in the @odata.count property along with the results of the query.

Section 5: Pagination

Some queries return a large number of rows, and it's easier to view them one page at a time. To retrieve paginated results, use the odata.maxpagesize option instead of $top.

In this example, we ask for a $count and set the odata.maxpagesize to 4. This filter matches 10 contacts, but we're only retrieving 4 at a time. We also use the count and the max page size to figure out how many pages there are. The result of the first page is returned in this request.

Section 6: Expand results

To retrieve information on associated table rows, use the $expand query option on navigation properties. More information: Join Tables

A single-valued navigation property represents a many-to-one relationship. In our sample data, the account has a relationship with a contact through the primarycontactid column, or attribute. In this relationship, the account can have only one primary contact. Using the account EntityType, we can create a query to get information about the account and expanded information about its primary contact.

Console output:

Account Contoso, Ltd. (sample) has the following primary contact person:

        Jobtitle: Coffee Master
        Annualincome: 45000

Expand on partner property

Each navigation property has a corresponding "partner" property. After an association is made, we can retrieve information through it. Which column we use depends on the base table we query.

For example, in the previous operation, we created a query against the account entity type. We wanted to get more information about its primary contact, so we used the primarycontactid column, or attribute. If we look up the account entity type, in the single-valued navigation properties section we find that the partner property of primarycontactid is the account_primary_contact collection-valued navigation property, which is found in the contact entity type.

If you build a query against a contact, you can expand on the account_primary_contact column to get information about accounts where the contact is the primary contact. In the sample data, Yvonne McKay (sample) is the primary contact person for only one account. However, Yvonne can potentially be assigned to other accounts as the primary contact. Because the account_primary_contact property has a many-to-one relationship, the result is returned as an array of account rows.

Console output:

Contact 'Yvonne McKay (sample)' is the primary contact for the following accounts:
        Contoso, Ltd. (sample)

Collection-valued navigation properties support one-to-many or many-to-many relationships. For example, in our sample data, the account has a relationship with many contacts through the contact_customer_accounts column, or attribute.

We can use the account entity type in a query to get information about the account and expand information about its contacts. In this case, the Contoso, Ltd. (sample) is associated with nine other contacts through the contact_customer_accounts collection-valued navigation property.

You can expand on as many navigation properties as the query requires. However, the $expand option can only go one level deep.

This example expands the primarycontactid, contact_customer_accounts, and Account_Tasks navigation properties of the account entity type. The query returns a response that contains information about the account and two collections, a contacts collection and a tasks collection. The sample code processes the collections separately.

Section 8: FetchXML queries

Besides query filter operations, the Web API also supports FetchXML queries. FetchXML provides an alternative way to define queries and more options for aggregation. All the query options we would normally define, such as $select, $filter, and $orderby, are defined in the XML.

To use FetchXML, compose a string that represents the query. Make sure the query string conforms to the FetchXml reference. Before you include the string in the URL, you must URL-encode it.

In this example, we query for all contacts where fullname matches (sample), and return the results in descending order by fullname.

This is the XML for the query:

<fetch mapping="logical" output-format="xml-platform" version="1.0" distinct="false">  
  <entity name="contact">  
    <attribute name="fullname" />  
    <attribute name="jobtitle" />  
    <attribute name="annualincome" />  
    <order descending="true"  
           attribute="fullname" />  
    <filter type="and">  
      <condition value="%(sample)%"  
                 attribute="fullname"  
                 operator="like" />
      <condition value="7d716234-9628-ed11-9db1-000d3a320482"
                 attribute="parentcustomerid"
                 operator="eq" /> 
    </filter>  
  </entity>  
</fetch>

In this example, the query is sent using a $batch request. FetchXML queries can be long, so they can reach the limits for URLs that can be sent using GET. With a $batch operation, the URL is sent in the body of the request, where the limits are higher.

FetchXML pagination

The way FetchXML handles paging is different from how a query filter handles it. In FetchXML, you can specify a count column that indicates how many results to return per page. In the same request, use the page column to specify the page number to return.

The following operation requests page 2 from the previous FetchXML sample. Based on our sample data, we should have eight contacts in our result. Breaking down each page to four contacts per page, we should have two pages. Page 2 should contain only four contacts. If we then ask for page 3, the system returns zero results.

        output-format="xml-platform"

Section 9: Use predefined queries

You can use the Web API to retrieve and execute predefined queries.

Saved query

In this operation, we request the savedqueryid GUID of the saved query named Active Accounts. Then we use the GUID and the savedQuery parameter to query for a list of active accounts.

First, we get the saved query's GUID.

Request:

      "savedqueryid": "00000000-0000-0000-00aa-000010001002"
    }
  ]
}

Next, we use the savedQuery parameter to get the saved query's content.

OData-EntityId: [Organization Uri]/api/data/v9.2/userqueries(f76e86e2-a228-ed11-9db1-000d3a320482)

This user query asks for any contacts where fullname contains (sample), jobtitle contains manager, and annualincome is greater than 55000. Our sample data has two contacts that match the query.

In the sample code, the userqueryid value is returned with the request that creates it. Normally, you'd need to query the system to retrieve it using a query like the following one:

Request:

GET https://[Organization URI]/api/data/v9.2/userqueries?$select=name,userqueryid,&$filter=name%20eq%20'My%20User%20Query' HTTP/1.1  
OData-MaxVersion: 4.0  
OData-Version: 4.0  
Content-Type: application/json; charset=utf-8

Response:

HTTP/1.1 200 OK
Content-Type: application/json; odata.metadata=minimal  
OData-Version: 4.0  
Content-Length: 246  
  
{   
   "@odata.context":"https://[Organization URI]/api/data/v9.2/$metadata#userqueries(name,userqueryid)",  
   "value":[   
      {   
         "@odata.etag":"W/\"621698\"",  
         "name":"My User Query",  
         "userqueryid":"f76e86e2-a228-ed11-9db1-000d3a320482"  
      }  
   ]  
}

This example passes the GUID value with the userQuery parameter to get the user query's content.
