In this tutorial, we are going to learn about how to get the url params from a current route in react using react-router.

Getting the URL params

If you need to do something custom like send requests through a proxy, you can also use fetch method directly with custom options from the fetch spec. Let promise = fetch(urloptions) url – the URL to access. Options – optional parameters: method, headers etc. Without options, this is a simple GET request, downloading the contents of the url. If using node, you can add the fetch API through a package like node-fetch. URLSearchParams comes with node, and can be found as a global object since version 10. In older version you can find it at require ('url').URLSearchParams. Small portions of information can be easily passed via URLs from one component to the other which is not sensitive and can be shared publically. It can be an ID of a record that can be fetched on other details component to fetch and display information related to that ID. Parameters can be passed and get in 3 ways in an Angular application.

To get the url parameter from a current route, we can use the useParams() hook in react router v5.

Consider, we have a route like this in our react app.

Now, we can access the :id param value from a Users component using the useParams() hook.

Users.js

In React router v4, you can access it using the props.match.params.id.

Users.js

In class-based components, you can access it like this.

Users.js

If you don't have a props object inside your react component, then you need wrap with a withRouter() higher-order function.

Note

Effective November 2020:

  • Common Data Service has been renamed to Microsoft Dataverse. Learn more
  • Some terminology in Microsoft Dataverse has been updated. For example, entity is now table and field is now column. Learn more

This article will be updated soon to reflect the latest terminology.

In Microsoft Dataverse, FetchXML includes grouping and aggregation features that let you calculate sum, average min, max and count.

The following aggregate functions are supported:

  • sum
  • avg
  • min
  • max
  • count(*)
  • count(attribute name)

About aggregation

To create an aggregate attribute, set the keyword aggregate to true, then specify a valid entity name, attribute name, and alias (variable name). You must also specify the type of aggregation you want to perform.

The following example shows a simple aggregate attribute in FetchXML.

The result of a query with an aggregate attribute is different from the results of a standard query. The alias value is used as the tag identifier for the aggregate result.

The following example shows the format of the result of an aggregate query.

The following example shows the results of a query when the alias variable is set to account_count.

Limitations

Queries that return aggregate values are limited to 50,000 records. This limit helps maintain system performance and reliability. If the filter criteria in your query includes more than 50,000 records you will get the following error:

Error code: -2147164125
Hexadecimal error code: 8004E023
Platform error message: AggregateQueryRecordLimit exceeded. Cannot perform this operation.
Client error message: The maximum record limit is exceeded. Reduce the number of records.

To avoid this error add appropriate filters to your query to ensure that it will not need to evaluate more than 50,000 records. Then run you query multiple times and combine the results.

Tip

If you want to get a total count of records with no filter, use the RetrieveTotalRecordCount message with either the Web API RetrieveTotalRecordCount Function or with the Organization service RetrieveTotalRecordCountRequest message class.

Avg

The following example shows how to use the avgaggregate attribute.

Limitation with null values while computing average

Null values are not considered when Dataverse computes the average of data. However, zero (0) is used.

In the following example, with the following data, the average for Account 1 (two entries) is shown as 250 whereas the average for Account 2 (two entries) is shown as 125.

TopicPotential CustomerEstimated value
Opportunity 1Account 1null
Opportunity 2Account 1250
Opportunity 3Account 20
Opportunity 4Account 2250

Count

The following example shows how to use the countaggregate attribute.

CountColumn

The following example shows how to use the countcolumnaggregate attribute to count columns.

Count distinct columns

The following example shows how to use the countcolumnaggregate attribute with the distinct attribute to count distinct columns.

Max

Null values are not considered when Dataverse computes the maximum of data. However, zero (0) is used.

The following example shows how to use the maxaggregate attribute.

Min

Null values are not considered when Dataverse computes the minimum of data. However, zero (0) is used.

The following example shows how to use the min``aggregate attribute.

Sum

The following example shows how to use the sum``aggregate attribute.

Multiple aggregates

The following example shows how to use multiple aggregate attributes to set a minimum and maximum.

Group by

The following example shows how to use multiple aggregate attributes and a linked groupby attribute.

The samples below show the following group by examples:

Group by with linked entity

The following example shows how to use the sum``aggregate attribute to sum linked entity values.

Group by year

Group By for dates uses the day, week, month, quarter, or year value. The following example shows how to use the aggregate attribute and the groupby attribute to group the results by year.

Group by quarter

The following example shows how to use the aggregate attribute and the groupby attribute to group the results by quarter.

Group by month

The following example shows how to use the aggregate attribute and the groupby attribute to group the results by month.

Group by week

The following example shows how to use the aggregate attribute and the groupby attribute to group the results by week.

Group by day

Fetch Get

The following example shows how to use the aggregate attribute and the groupby attribute to group the results by day.

Multiple group by

The following example shows how to use the aggregate attribute and multiple groupby clauses.
