DGET returns the value of the field specified in the second argument (similarly to a VLOOKUP) only when exactly one record matches Criteria otherwise, it returns an error indicating no matches or multiple matches. I'm using Pure Data for a project where I'll be playing several audio files at the same time to different speakers. A field name may appear more than once in the Criteria range to allow multiple restrictions that apply simultaneously (for example, temperature >= 65 and temperature <= 82).ĭGET is the only database function that doesn't aggregate values. A database row (a record) satisfies Criteria if at least one filter matches it. An empty cell means no restriction on the corresponding field.Ī filter matches a database row if all the filter restrictions (the restrictions in the filter's row) are met. Examples of restrictions are: "Chocolate", "42", ">= 42", and " 42". Restrictions are described using Query-by-Example notation and include a value to match or a comparison operator followed by a comparison value. Every other row in Criteria represents a filter, a set of restrictions on the corresponding fields. But data on a chart or on a map, data portrayed simply, yet so very efficiently, data. Sure, data alone, numbers aligned on some kind of boring white sheet, can only ever be beautiful to a mathematician. The first row in Criteria specifies field names. It’s just charts and infographics and numbers There’s absolutely nothing beautiful about that And, well, that’s where you’re wrong. The circuitry which drives the audiovisual is made up of a potentiometer, a photocell and 10K resistor. Arduino is employed in order to generate incoming data. Pure Data is used to create both the audio and the visual components. It is structured such that the first row contains the field name(s) to which the criterion (criteria) will be applied, and subsequent rows contain the conditional test(s). The concept behind this project was to create an audio visual which was driven by external inputs.
