I haven't tested these on an ArangoDB server so some typo's may exist. This presentation covers AQL, ArangoDBs query language. Importantly the column names can't by fully dynamic, but can be user selected. arangodb/Functions. AQL user functions are a means to extend the functionality of ArangoDB’s query language (AQL) with user-defined JavaScript code. numArray (array): an array of numbers, null values are ignored returns mean (numbernull): the. ![]() Build high performance applications using a convenient SQL-like query language or JavaScript extensions. Return the average (arithmetic mean) of the values in array. This isn't pretty, but works, and with creativity you can write heavily nested and complex queries with ASC and DESC as options, as well as a predefined number of column names. ArangoDB is a native multi-model database with flexible data models for documents, graphs, and key-values. LENGTH () can also determine the number of elements in an array, the number of attribute keys of an object / document and the amount of documents in a collection.

I sometimes generate AQL dynamically, but all parameters are carefully scanned, cleansed, Joi schema proofed, and validated to stop SQL injection. RETURN = 'createdAt' ?īut the other way is to dynamically generate the AQL, with proper code checking you can do it safely. Pure AQL, you can do this but somewhere in the world a puppy will die. If a number is passed, it will be casted to string first. How can I sort result basing on different input arguments? Determine the character length of a string. Lets say I have sort object that could look like this: var sort =, 'f') I'd like to have sorted result depending on user input. ![]()
