Code Like A Girl·2ySQL Essentials: GROUP BY vs. PARTITION BY explained
Understanding the differences between GROUP BY and PARTITION BY clauses in SQL is crucial for efficient data analysis. GROUP BY is used to summarize data by grouping rows that have the same values in specified columns, while PARTITION BY is used for detailed calculations within specific partitions. GROUP BY can reduce the number of rows by summarizing data, whereas PARTITION BY adds additional information without reducing rows. Both clauses support aggregate functions, but PARTITION BY also supports ranking and time-series functions.

Atomic Spin·1yOptimize EF Core Database Query Performance
In a project where PDFs were migrated from a Blob Storage container to a SQL Server database, the web app's performance dropped significantly. To address this, several strategies were used to optimize EF Core query performance: using AsSplitQuery to avoid data duplication, employing projections and DTOs for read-only data to retrieve only necessary columns, and creating indexes for frequently queried non-primary key fields. These optimizations led to a reduction in response times and overall improved performance.

Neon·1yWhat To Know About Postgres if You’re Coming From SQL Server
Microsoft SQL Server and Postgres both share their origins in 1989, but they have grown in different directions. SQL Server uses T-SQL, while Postgres uses PL/pgSQL, each with distinct syntax and features for procedural programming, string delimiters, date functions, and more. Postgres, an open-source community-driven database, offers flexibility and earlier access to innovative features compared to the company-driven SQL Server. Switching from SQL Server to Postgres includes adapting to different syntactical nuances but opens up a broader range of tools and hosting options.
The Art of Simplicity·2ySQL Server–Does a ‘LIKE’ query benefits from having an index?
A LIKE query in SQL Server can benefit from an index, although its effectiveness depends on how the LIKE pattern is constructed. Queries with a suffix wildcard (e.g., 'Laptop%') are efficient with index usage, while prefix wildcards (e.g., '%Pro') do not benefit effectively. Partial wildcards (e.g., 'Lap%op') may partially benefit, and queries without wildcards fully benefit from the index.
