Looker filter parameter example. Parameter ID: set by default.
- Looker filter parameter example Step 3 – Apply the new dimension to a new chart and use the new parameter as a filter to edit the brand terms; Creating a forecast parameter:. percent_of_previous The previous example of a merged query element demonstrates how to apply hard-coded filters directly within each source query by using the filters parameter. As part of MTLA’s Limit-5 series, we will now go over a step-by To use a parameter in your custom query, follow the relevant syntax guidelines documented in Running parameterized queries. The dimensions provided in the filters sub-parameter identify the Before legacy dashboard deprecation in Looker 23. However, controls in Looker Studio cannot filter charts based on different data source types. - name: orders_by_date type. Within each view are field definitions, each of which typically corresponds to a column in the underlying table or a calculation in Looker. 1. merged query element demonstrates how to apply hard-coded filters directly within each source query by using the filters parameter. For example, the filters companies. state: 12. Both perform the same functionality, but now we'll dive into controls and To hide a filter, you add a hide_filter parameter to the URL, preceded by an ampersand (&) and followed by an equal sign (=), and give the parameter the value of the filter name, with any spaces in the name replaced Filter Parameters: access_filter: Adds user-specific filters to an Explore: always_filter: Adds filters a user can change, but not remove, to an Explore: case_sensitive (for Explore) Specifies whether filters are case-sensitive for an Explore: conditionally_filter: Adds filters to an Explore if a user does not add their own filter from a Parameter Name Description Example; bind_filters: Passes a filter from the Explore query into the native derived table subquery. always_filter overrides the default_value setting for the field. For the example above, whichever of the three Add a parameter to a database data source. For example, filters of type: day_picker can only be displayed as inline or overflow. This page refers to the type parameter that is part of a dimension or filter.

Here is an example of a datagroup that has a sql_trigger set up to rebuild the PDT This page describes the parameters for creating and editing LookML dashboard elements of type: looker_map with LookML dashboard parameters in a dashboard. If you don't declare a value with always_filter, then "is any value" is the filter default in the Explore. A parameter creates a filter-only field Templated Filters are a great way to make your derived tables more dynamic by using Liquid templating language to insert user input directly into our SQL queries. Both filters will be applied unless the user sets an order date in the Explore UI. Please create a new Big Query Custom Query datasource, in this example we’re going to be very basic: always_filter: { filters: [products. For example, the The previous example of a merged query element demonstrates how to apply hard-coded filters directly within each source query by using the filters parameter. lkml file. Definition. type can also be used as part of a For example, you can add helpful filters that most users would expect to use on an Explore, or you can add a default filter to minimize the risk of queries straining your database resources. This example also demonstrates that you can require multiple filters. Registration Type, Visitor Type but upon selection of a label corresponding value is passed for See the Using URLs and query parameters Looker Community post for information on the parts of a query URL. Looker's symmetric aggregates will not protect aggregate functions in the SQL of a measure type: number when computed across a join. For information about the types of fields required to build an 12. Report viewers don't see it. #1 contributor on Google's gallery Trusted by 3,123 clients worldwide Over 4,000+ templates sold Templates. (Ref Fig 1. The parameter ID is used internally by Looker Studio to identify the parameter. This page provides an overview of each LookML parameter that affects filtering for Parameter name: you'll see this name in the lists of fields in your reports and data sources. Note: As per need, many more values can be passed in parameter using allowed_value. 6, the preferred_viewer parameter let you choose the format for viewing and downloading a dashboard as either Looker's default dashboard experience or as a legacy dashboard. field_name'] variable in its link parameter to pass an existing filter value for a field called users. 9. The customer. sql lets you specify the SQL that will be used to generate a derived table. . First, let’s review how to add a parameter to a simple custom query. 0 License . We’ll be using Big Query here (please note that not all database connections accept parameters). 0 License , and code samples are licensed under the Apache 2. type can also be First, we use LookML parameter/templated filter to create a filter only field for users to interact with and then, use a Liquid variable to inject the user input into SQL queries. The aggregate_table parameter is used to create aggregate tables that will minimize the number of queries required for the large tables in your database. id filter refers to the id field from the view called customer. Filtered measures let you apply a hardcoded filter directly to a measure, rather than applying a filter to an entire query. Parameters let you build more responsive, customizable reports. The previous example of a merged query element demonstrates how to apply hard-coded filters directly within each source query by using the filters parameter. As we can see in our example above, we are naming our filter-only field the exact same as when we referenced it during STEP 2. To use a parameter in your custom query, follow the relevant syntax guidelines documented in Running parameterized queries. First, you use a LookML parameter to create a field for users to interact with. 1) The parameter is surfaced as a filter-only field in the UI and the user will see only labels e. Note: If your Looker admin has enabled the Accessible Data Table Visualizations Labs You can use the case parameter to create custom-named buckets with custom sorting. Once Note: This page is part of the Retrieve and chart data learning series. The dev_filters parameter acts in conjunction with the filters parameter so that all filters are applied to the development version of the table. All the data appears in the Looker Studio report. Example 2. In addition to referencing Parameter name: you'll see this name in the lists of fields in your reports and data sources. The filters parameter cannot be used with type: number measures, but the filters documentation explains a workaround. A practical use case for text parameters is creating a mini-tool like a UTM link generator. You can use any legal SQL query in the sql parameter, as long as the SQL query is written in raw SQL and does not reference Looker fields. Filter Parameters: case_sensitive (for model) Specifies whether filters are case-sensitive for a model: Query Parameters: connection: Changes the database connection for a model: datagroup: Creates a datagroup-caching policy for a model. This is also the name you'll use to refer to the parameter in a calculated field. Rick is signed in, so only his data appears when he views a report that is based on the filtered data source. This parameter has the label, description, max_cache_age, and sql_trigger subparameters. valuation_amount: NOT NULL in This page demonstrates how to add and customize a LookML dashboard element of type: looker_grid with LookML dashboard parameters in a dashboard. Imagine a control (in yellow) that's connected to a Google Analytics data source. Let's look at a few For Looker Studio documentation, visit https://support. For example, with case, a user will be able to select only the defined bucket values in a filter. filter_date field and apply the filter to the users. Here is an example of a dimension that uses the _filters['view_name. com/looker-studio. The case parameter is recommended for a fixed set of buckets, as it can help control the way values are presented, ordered, and used in UI filters and visualizations. Looker uses aggregate awareness logic to find the Each filter can accept a Looker filter expression or a value constant. A useful application of the CASE function is extracting URL query parameters, such as custom dimensions for reporting and aggregation. Select_dimension is the string type parameter which needs to be created first. Report URL: By adding a link, you can fetch data from different online sources such as Facebook Ads. contact_email: "-NULL" and ipo. valuation_amount: NOT NULL in If you define a datagroup with both parameters, the datagroup will use the interval_trigger value and ignore the sql_trigger value, since the sql_trigger parameter requires Looker to use database resources when querying the database. Understand the use case and benefits of creating a UTM link generator tool. google. For a more complete understanding of derived tables, see the Derived tables in Looker documentation page. type can also be used as part of a join, described on the type (for joins) parameter documentation page. type: number measures will not provide suggestions to users. A view represents a table of data in Looker, whether that table is native to your database or was created using Looker's derived table functionality. In our last session, we explored filters and controls in Looker Studio, which allowed us to narrow down the information presented in our reports based on certain dimension values or metric ranges. If you declare a value with always_filter, that value will be the default in the Explore. In this example, we want to extract search query To read more about how Liquid works and to see an example that swaps fields instead of aggregation type, visit the Looker documentation here. They are also used in LookML for elements that take a filter parameter. Parameter Example: UTM Generator. Step 1: How can we extract search query parameters from a URL dimension? We can do it using CASE, CONTAINS_TEXT(), and REGEXP_EXTRACT() functions which we will demo on this lesson. If you filter by "United States," the charts based on Google Analytics data sources will refresh to display data only from the United States. In this case the id filter refers to the id field from the Explore called order. type can also be used as part of a dashboard filter, described on the Dashboard parameters documentation page. In the underlying view file, we can create a Parameters in Looker increase interactivity for users and provide flexibility from the front end perspective without having to write custom code for each and every field the user asks for. Example: Filtering Limitations. This section refers to the type parameter that is part of a dashboard element. At runtime, any filters on the from_field in Learn how to create and use the dynamic parameters in Looker Studio. category: "-EMPTY"] } The always_filter parameter overrides a default_value filter setting. In the preceding bind_filters example, Looker will take any filter applied to the filtered_lookml_dt. g. Introduction to Parameters. For information about building an interactive map chart through the Looker UI, see the Map chart options documentation page. In this example, the data source has an email filter. If you had a limited number of timeframes that you were interested in comparing, you could define a few measures with hardcoded timeframe filters (for example, "this year" and "last year") and display them in an Explore, a Look, or a dashboard. Filter expressions are an advanced way to filter Looker queries, and this page describes how to write them. Views are typically declared in view files, with one view per file. You can use the following parameters in any custom query: You can also use filters with Liquid parameters and templated filters to create dynamic filtered measures with a filter value that can change dynamically based on user input Filter: You can add a filter control on your report to allow the viewers to change the values of the parameters. Learning Objectives. However, if your example calls for a different data type then you may specify it here. Next, you use a Liquid variable to inject the user input into SQL queries. To set up this parameter, use the from_field subparameter to specify a field defined in the native derived table view or accessible in the Explore to which the native derived table is joined. You can pass parameters in a data source back to the underlying query. Parameters allow us to display these different metrics in a single tile based on a user’s filter selection! How? Let’s dig in deeper. You can use the following parameters in any custom query: The always_filter has a sub-parameter to define the specific filters using the same Looker filter expressions that are used to filter dimensions and measures. We learned that filters are designed for editors and controls for viewers. If your data is in BigQuery, you can also use the email parameter in a custom query to filter by email address. In the Explore section of Looker you can use them by adding a filter and choosing the matches (advanced) option. Parameter ID: set by default. valuation_amount: NOT NULL in. Furthermore, for our example, the type will be string, as we want our users dynamically inputting a string into our WHERE clause. For information about building a table chart through the Looker UI, see the Table chart options documentation page. This can be useful for marketing teams who want to generate UTM links for their campaigns. If an explore parameter has a value specified by an always_filter parameter, then that setting overrides the default_value setting for the field. fiscal_month_offset Definition.
