<p>This page covers more common patterns in LookML.</p> <p><a name="labeling_fields_(and_names_in_the_ui)"></a></p> <h1>Labeling fields (and names in the UI)</h1> <p>Looker converts LookML field names into the strings displayed in the UI by combining the view name in regular-weight font with the field’s short name in bold. For example, a field called <strong>Amount</strong> in the <strong>Orders</strong> view would appear in the UI as Orders <strong>Amount</strong>. On this page, they are both bolded and the view name is capitalized (<strong>ORDERS Amount</strong>) to make the discussion clearer.</p> <p>If you would like a field to be named differently than its column name in a table, simply change the field name and declare its <code>sql:</code> linkage. In the example below, there is a table <code>airports</code> with a column <code>cntrl_twr</code>. Looker would generate the following declaration:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> view: airports { dimension: cntrl_twr { # full name: airports.cntrl_twr type: yesno # default name: AIRPORT Cntrl Twr (Yes/No) sql: ${TABLE}.cntrl_twr ;; # the sql expression for this field } } </div></p> <p>We will rename the <code>cntrl_twr</code> dimension to be human-readable.</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> view: airports { dimension: has_control_tower { # full name: airports.has_control_tower type: yesno # aliased name: AIRPORTS Has Control Tower (Yes/No) sql: ${TABLE}.cntrl_twr ;; # the sql expression for this field } } </div></p> <p><a name="filtering_counts_by_a_dimension"></a></p> <h1>Filtering counts by a dimension</h1> <p>It is pretty easy to group by a dimension and count entities — grouping by <strong>USERS Country</strong>, <strong>ORDERS Count</strong> will tell you where your orders are coming from by country. However, it is often useful to build a count filtered by some dimensional value. For example, you could make a new measure <strong>ORDERS France Count</strong>:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> view: users { dimension: country {} } view: orders { dimension: id { primary_key: yes sql: ${TABLE}.id ;; } measure: count { type: count drill_fields: [detail] } measure: france_count { type: count # COUNT(CASE WHEN users.country = ‘France’ THEN 1 ELSE NULL END) drill_fields: [detail] # Also, when drilling, adds the filter users.country=’France’ filters: [users.country: "France"] } } </div></p> <p>Filters can use any expression. If you wanted a field that counted users from the EU, you could use something like this:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> measure: eu_count { type: count # COUNT(CASE WHEN users.countrycode IN ‘UK’,’FR’,’ES’ THEN 1 ELSE NULL END) drill_fields: [detail] filters: [users.countrycode: "UK,FR,ES"] } </div></p> <p>If you want to <a href="/web/20210801173733/https://docs.looker.com/exploring-data/creating-looker-expressions/looker-functions-and-operators#math">filter with a mathematical expression</a>, be sure to enclose it in double quotes:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> measure: total_orders_above_100_dollars { type: sum # SUM(CASE WHEN order.value > 100 THEN order.value ELSE NULL END) sql: ${order.value} ;; drill_fields: [detail] filters: [order.value: ">100"] } </div></p> <p><a name="percentages"></a></p> <h1>Percentages</h1> <p>Many key performance indicators are expressed in the form of percentages, such as “the percent of items returned,” “the percent of emails that resulted in a sale,” or other instances of “the percent of X that Y.” In LookML, the design pattern is to create counts for the two conditions and create a third field that computes the percentage between the two.</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> dimension: returned { type: yesno } measure: count { # total count of items type: count_distinct sql: ${TABLE}.id ;; drill_fields: [detail] } measure: returned_count { # count of returned items type: count_distinct sql: ${TABLE}.id ;; drill_fields: [detail] filters: [returned: "Yes"] } measure: percent_returned { type: number sql: 100.0 * ${returned_count} / NULLIF(${count}, 0) ;; value_format: "0.00" } </div></p> <p>Use the form below when computing percentages. In Postgres, counts are integers, and division between integers results in integers. Multiplying by 100.0 converts the first count to a floating point number, thus converting the rest of the expression to a float. In order to avoid divide-by-zero errors, the <code>NULLIF(value, 0)</code> will convert a zero value to null, making the result null and avoiding an error.</p> <div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> 100.0 * ${returned_count} / NULLIF(${count}, 0) </div> <p><a name="using_sets_for_drill-down_details"></a></p> <h1>Using sets for drill-down details</h1> <p>One of the most powerful features of Looker is the ability to drill into data to see the underlying entities that make up a count or other measure.</p> <p>When a measure is clicked on the Looker UI, a new query is created localizing the set of data making up the measure. Each value for each dimension on the row in the table gets added to the current filters.</p> <p>In order to show the detail, Looker needs a specified list of drill fields to show when the measure’s value has been clicked. When you <a href="/web/20210801173733/https://docs.looker.com/data-modeling/getting-started/connect-to-db-and-generate-model">generate a model</a>, the generator typically creates some initial drill fields for you. In addition, you can add drill fields yourself. For example, assume that we are measuring <strong>ORDERS Count</strong> by <strong>USERS State</strong> in the last week. In Looker, the query would look something like this:</p> <table> <tr><th>USERS State</th><th align="right">ORDERS Count</th></tr> <tr><td>California</td><td align="right">24</td></tr> <tr><td>Texas</td><td align="right">5</td></tr> <tr><td>Colorado</td><td align="right">4</td></tr> <tr><td>Florida</td><td align="right">4</td></tr> <tr><td>Illinois</td><td align="right">4</td></tr> </table> <p>If we click on <strong>24</strong> in the <strong>California</strong> row, the expected behavior is that we’d see the 24 orders that came from California.</p> <p>Looker handles adding the filter <strong>USERS State: California</strong>, but Looker doesn’t know which fields you want to show in the order. You’ll need to use a set to declare those fields in your model.</p> <p>In LookML, a <strong>set</strong> is a list of field (dimension, measure, and <a href="/web/20210801173733/https://docs.looker.com/reference/field-params/filter">filter</a>) names. Sets are used to tell Looker which fields:</p> <ul> <li>You want to show when drilling into a count or other measure</li> <li>To import when joining a view</li> <li>Are indexed in an Explore</li> </ul> <p>The same set can be used in many places in a model, so Looker provides several ways of creating sets.</p> <p><a name="literal_sets"></a></p> <h2>Literal sets</h2> <p>The simplest form of a set is a literal set. A literal set is created by simply declaring the set as an array. You can declare literal sets by using ‘[]’.</p> <p>Given this example:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> view: customers { dimension: id { primary_key: yes } measure: count { type: count } dimension: city {} dimension: state {} dimension: name {} } </div></p> <p>The fields we’d like to show are <code>id</code>, <code>name</code>, and <code>city</code>.</p> <p>In the measure, we could simply declare a literal array.</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> measure: count { type: count drill_fields: [id, name, city] } </div></p> <p>For sets that are only used once, declaring them literally is simple and easily understood.</p> <p><a name="named_sets"></a></p> <h2>Named sets</h2> <p>Suppose we have two counts: <strong>CUSTOMERS Count</strong> and <strong>CUSTOMERS In California Count</strong>. When we drill into either of these counts, we’d like to show the fields <code>id</code>, <code>name</code>, and <code>city</code>. If we declare the fields literally, we could:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> view: customers { measure: count { type: count drill_fields: [id, name, city] } measure: in_california_count { type: count drill_fields: [id, name, city] filters: [state: "California"] } } </div></p> <p>If we wanted to add a new field (say the field <code>customers.state</code>), we’d have to edit both lists. Instead, LookML provides a way to create named sets that we can maintain in one place and use in multiple places.</p> <p>The code below creates a set <code>customers.detail</code> and points both counts to the same set of fields.</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> view: customers { set: detail { fields: [id, name, city] # creates named set customers.detail }   measure: count { type: count drill_fields: [detail*] # show fields in the set "customers.detail" } measure: in_california_count { type: count drill_fields: [detail*] # show fields in the set "customers.detail" filters: [state: "California"] } } </div></p> <p>LookML sets are pretty powerful:</p> <ul> <li>Redeclaration of sets is additive — if you declare a set in multiple places, then Looker includes all of the fields declared for the set in all locations.</li> <li>You can embed sets in other sets by typing the other set name, followed by an asterisk, like <code>setname*</code>.</li> <li>You can even remove elements from sets by placing a hyphen before the field name, like <code>-fieldname</code>.</li> </ul> <p><a href="/web/20210801173733/https://docs.looker.com/reference/view-params/sets">Read the full sets reference</a></p> <p><a name="customizing_drill_visualizations"></a></p> <h2>Customizing drill visualizations</h2> <p> </p> <p>If your Looker admin has enabled the <a href="/web/20210801173733/https://docs.looker.com/admin-options/settings/labs#visual_drilling"><strong>Visual Drilling</strong></a> Labs feature, drill visualizations will not always default to a data table. In this case, you can customize the visualization displayed by using Liquid variables in the <code>link</code> parameter, as shown on the <a href="/web/20210801173733/https://docs.looker.com/reference/field-params/link#using_link_to_customize_drill_visualizations"><code>link</code></a> parameter documentation page and in the <a href="https://web.archive.org/web/20210801173733/https://help.looker.com/hc/en-us/articles/360023589613--More-Powerful-Data-Drilling">More powerful data drilling</a> Help Center article.</p> <p> The <a href="/web/20210801173733/https://docs.looker.com/dashboards/new-dashboard-experience">new dashboard experience</a> supports visual drilling using the <code>link</code> parameter without the need to enable the <strong>Visual Drilling</strong> Labs feature.</p> <p><a name="filtering_result_sets"></a></p> <h1>Filtering result sets</h1> <p>LookML provides a set of filter operations that can be applied to fields and Explores to filter result sets before they are returned to the user.</p>  <p><a name="always_filter_on_the_explore"></a></p> <h2><code>always_filter</code> on the Explore</h2> <p>Use <a href="/web/20210801173733/https://docs.looker.com/reference/explore-params/always_filter"><code>always_filter</code></a> to always apply a set of filters to any query run within an Explore. The filters will appear in the Looker UI, and though users can change the default filter value that you provide, they cannot remove the filters. Generally, these filters are used to remove data that you normally don’t want to included. For example, suppose in the <strong>Orders</strong> Explore we only wanted to see orders that were complete or pending. We could add:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> explore: orders { view_name: order always_filter: { filters: [status: "complete,pending"] } } </div></p> <p>If the user wanted to see orders with other status values, they could set <strong>ORDERS Status</strong> to <strong>%</strong> in the UI.</p> <p><a name="sql_always_where_on_the_explore"></a></p> <h2><code>sql_always_where</code> on the Explore</h2> <p>If you want to apply a query restriction that users cannot change, you can use <a href="/web/20210801173733/https://docs.looker.com/reference/explore-params/sql_always_where"><code>sql_always_where</code></a>. In addition to queries run by human users, the restriction will apply to dashboards, scheduled Looks, and embedded information that relies on that Explore. A <code>sql_always_where</code> condition is not displayed to the user, unless they look at the underlying SQL of any queries that they create.</p> <p>The following example prevents users from looking at orders before 2012-01-01:</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> # Using Looker references explore: order { sql_always_where: ${created_date} >= '2012-01-01' ;; }   # Using raw SQL explore: order { sql_always_where: DATE(created_time) >= '2012-01-01' ;; } </div></p> <p><a name="conditionally_filter_on_the_explore"></a></p> <h2><code>conditionally_filter</code> on the Explore</h2> <p>Very large tables require some thought when querying, since unlimited queries can quickly become too burdensome on the database. LookML provides a way to address this in the form of <a href="/web/20210801173733/https://docs.looker.com/reference/explore-params/conditionally_filter"><code>conditionally_filter</code></a>.</p> <p>You use the <code>conditionally_filter</code> parameter to apply a filter to the query unless the user has already added a filter for one of the fields listed in the <code>unless</code> section.</p> <p>The following example won’t make any change to the user’s query if the user applied a filter on one or more of these fields: <code>created_date</code>, <code>shipped_time</code>, <code>shipped_date</code>, <code>orders.id</code>, or <code>customer.name</code>. If the user didn’t filter on any of those fields, Looker will automatically add a filter of 1 day on <code>orders.created_time</code>.</p> <p><div class="code" ace-mode="ace/mode/lookml" ace-theme="ace/theme/lookml" ace-gutter=""> conditionally_filter: { filters: [orders.created_time: "1 day"] unless: [created_date, shipped_time, shipped_date, orders.id, customer.name] } </div></p> <div class="prev-next"> <p class="prev"><a href="/web/20210801173733/https://docs.looker.com/data-modeling/learning-lookml/sql-and-referring-to-lookml"><i class="material-icons">keyboard_arrow_left</i>Incorporating SQL and Referring to LookML Objects</a></p> <p class="next"><a href="/web/20210801173733/https://docs.looker.com/data-modeling/learning-lookml/working-with-joins">Working with Joins in LookML<i class="material-icons">keyboard_arrow_right</i></a></p> </div> </article> </main> <footer> <h2>Other resources</h2> <div id="resource-container"> <div id="discourse" class="resource"> <h3><i class="material-icons">help_center</i> Help Center</h3> <p>Our Help Center contains additional, short articles on specific use cases and special situations.</p> <a href="https://web.archive.org/web/20210801173733/https://help.looker.com/"><button>Go to Help Center</button></a> </div> <div id="discourse" class="resource"> <h3><i class="material-icons">forum</i> Community</h3> <p>Looker’s Community forums are a great place to discuss best practices, troubleshoot unique issues, and communicate with other Looker customers.</p> <a href="https://web.archive.org/web/20210801173733/https://community.looker.com/" class="gtm-discourse-link"><button>Go to Community</button></a> </div> <div id="support" class="resource"> <h3><i class="material-icons">school</i> Learn</h3> <p>Learn is Looker’s sandbox environment, primarily for developers.
