What type of field allows you to lookup values from one other table in Servicenow?
Note: These methods are designed for use in server-side JavaScript (everything EXCEPT client scripts and UI policies). In some rare cases, it may be necessary to perform a query from a client-side javascript (client script or UI policy). The few methods below that can be used in client-side JavaScript have been noted below. Show Query Can also be used in Client scripts and UI policies. A standard GlideRecord query follows this format. var gr = new GlideRecord('incident'); //Indicate the table to query from UPDATE: This same function applies to client-side GlideRecord queries! If at all possible, you should use an asynchronous query from the client. See this post for details. var gr = new GlideRecord('sys_user'); ‘Get’ Query Shortcut (used to get a single GlideRecord) Can also be used in Client scripts and UI policies IF YOU ARE GETTING A RECORD BY SYS_ID. The ‘get’ method is a great way to return a single record when you know the sys_id of that record. var gr = new GlideRecord('incident'); You can also query for a specific field/value pair. The ‘get’ method returns the first record in the result set. //Find the first active incident record ‘getRefRecord’ Query Shortcut (used to get a single GlideRecord referenced in a reference field) var caller = current.caller_id.getRefRecord(); //Returns the GlideRecord for the value populated in the 'caller_id' field ‘OR’ Query //Find all incidents with a priority of 1 or 2 Note that you can also chain your ‘OR’ condition as well, which is usually simpler //Find all incidents with a priority of 1 or 2 Insert //Create a new Incident record and populate the fields with the values below Update //Find all active incident records and make them inactive Delete //Find all inactive incident records and delete them one-by-one deleteMultiple Shortcut //Find all inactive incidents and delete them all at once addEncodedQuery CANNOT be used in Client scripts and UI policies! Use ‘addQuery(YOURENCODEDQUERYHERE)’ instead. An alternative to a standard query is to use an encoded query to create your query string instead of using ‘addQuery’ and ‘addOrCondition’ statements. An easy way to identify the encoded query string to use is to create a filter or a module with the query parameters you want to use, and then hover over the link or breadcrumb and look at the URL. The part of the URL after ‘sysparm_query=’ is the encoded query for that link. My encoded query string would be this… I could build that encoded query string and use it in a query like this… //Find all active incidents where the category is software or hardware GlideAggregate //Find all active incidents and log a count of records to the system log orderBy/orderByDesc //Find all active incidents and order the results ascending by category then descending by created date addNullQuery/addNotNullQuery //Find all incidents where the Short Description is empty //Find all incidents where the Short Description is not empty getRowCount //Log the number of records returned by the query Although ‘getRowCount’ isn’t available client-side, you can return the number of results in a client-side GlideRecord query by using ‘rows.length’ as shown here… //Log the number of records returned by the query setLimit //Find the last 10 incidents created chooseWindow //Find the last 10 incidents created setWorkflow //Change the category of all 'software' incidents to 'hardware' without triggering business rules on updated records What type of field allows you to look up values from one other table?Use a lookup field to find ("look up") values in one table that you can use in another table. A lookup field can provide values for a dropdown list and make it easier to enter data in a field.
What is a reference field in Servicenow?A reference field stores a reference to a field on another table. For example, the Caller field on the Incident table is a reference to the User [sys_user] table.
What is data lookup in Servicenow?The data lookup and record matching feature enables administrators to define rules that automatically set one or more field values when certain conditions are met. Data lookup rules allow administrators to specify the conditions and fields where they want data lookups to occur.
