![]() PostgreSQL does not support filtering on object key values in arrays. Using join: queries for filtering based on relationships, preload: queries for included resources and select: lists for sparse fieldsets, the generated queries. Before v2.23.0: you can filter on the exact Json field value, but you cannot use the other features described in this section.Īdvanced Json filtering is supported by PostgreSQL and MySQL only with different syntaxes for the path option.From v2.23.0, but before v4.0.0: advanced Json filtering is a preview feature.V4.0.0 or later: advanced Json filtering is generally available. The functions in this section perform search or comparison operations on JSON values to extract data from them, report whether data exists at a location.Filters narrow down the query results based on the given parameters. The availability of advanced Json filtering depends on your Prisma version: Updating a ForeignKey field works exactly the same way as saving a normal field. See also: Advanced example: Update a nested JSON key value Filter on a Json fieldįrom v2.23.0, you can filter rows by the data inside a Json type. Var hasOwnProperty = : JavaScript objects (for example, ) are automatically converted to JSON. As we’re going to see, there are many predefined filters that we can use. Each filter takes an input and emits JSON to standard out. The filter query parameter family is reserved to be used as the basis. The good news is that each one includes a polyfill (or way to create these methods if they are not included in your current JS version) so by adding those in to the top of our script, we can still use this method to get you the results you want. Working With Simple Filters jq is built around the concept of filters that work over a stream of JSON. The base specification is agnostic about filtering strategies supported by a server. In OpenSearch, this is very useful to query a JSON index with nested objects or fields. To that extent, I did some research and saw the two methods we needed to make this easy, but of course they are not native to SFMC SSJS: PartiQL extends SQL to allow you to query and unnest nested collections. SELECT COLUMNNAME FROM INFORMATIONSCHEMA.COLUMNS WHERE TABLENAME. So, my initial thought was similar to Adam Spriggs, but I then thought about that it had potential to be a lot of work if you had multiple DEs that might have different fields you need or you only know the fields you need and might not know the ones you need to remove. Since we need to be able to filter any table in the database, we should first get the columns that exist in the supplied table. Var dataRows = My_DE.Rows.Retrieve(complexFilter) Var My_DE = DataExtension.Init("EXTERNAL KEY HERE") akin to a SELECT FROM and am not sure how such a request might be crafted using a loop on the datarows results.Īny ideas / help - and ideally a working example of a loop if possible - would be much appreciated. This allows you to extract the element values. ![]() ![]() Using this filter, you can easily filter the. ![]() I can't find a way to do this in the retrieve process, i.e. Your filter definition makes such fields available for mapping to variables in actions. The query above would search the JSON fields for an exact match of hallo on all values, excluding the json keys. I'm building a SSJS custom API endpoint as a code resource page and have the following code which works fine but I need to limit the fields that are returned from the Data Extension and then placed in the JSON output - it currently returns all fields in the datarows and hence all fields are produced in the JSON array under Data Returned - that's just a dummy name for now. ![]()
