Some days you will open your laptop, stare at a SQL query for an hour, and produce absolutely nothing useful. The query runs.... The result is wrong.... You fix it.... Something else breaks... You start over... At this point you try to reassure yourself that, this is not failure, but the process.. The analysts who get good are not the ones who never struggle. They're the ones who don't close the laptop when they do. Keep going📊 #SQL #DataAnalysis #RealTalk #LearningInPublic #GrowthMindset

Views are a feature we have been asked about repeatedly, as they allow you to centralize your business logic rather than hardcoding queries directly into your program. Coming up next: user defined functions
Two SQL features that landed last week: - Full support for Views (temporary and persisted). The views are not materialized, as we already have a feature called “aggregated table” that gives you the benefit of materialized views without the downsides (see here: https://lnkd.in/gHHrRS4R). - SQL Sequence: a lesser-known feature that can come in handy when you need to share across multiple tables a unique numeric value generator. Use case example: a central event ID.
