How to Link Excel Directly to a SQL Database Using Power Query

0
·3 views

Data analyst Michael Nocito published a practical guide on August 8, 2026, explaining how to connect Microsoft Excel to SQL databases using the built-in Power Query tool. The method replaces manual export-and-paste workflows by recording data-cleaning steps and replaying them with a single Refresh All click. Power Query supports major databases including SQL Server, PostgreSQL, and MySQL, though SQLite requires a workaround covered separately in the guide. The tool is available on the Excel Data tab under labels such as Get Data or New Query, depending on the version, with full support on Windows and limited connector options on Mac. Nocito argues the approach eliminates not just repetitive steps but also a whole category of silent errors, such as data pasted into the wrong columns.

DNS to HTTP/3 and CORS: A Structured Beginner's Guide to Web Fundamentals

A technical explainer published on DEV Community walks beginners through the core protocols and systems that power the modern web. The piece covers how DNS translates human-readable domain names into IP addresses, detailing its four-layer hierarchy, record types, and the role of recursive resolvers. It also explains how DNS requests can be encrypted using DNS over TLS or DNS over HTTPS to prevent ISPs from monitoring browsing activity. The article further outlines the evolution of HTTP from version 1.1 through HTTP/2 and HTTP/3, describing improvements in speed, multiplexing, and transport protocols. CORS, which governs how browsers handle cross-origin resource requests, is also addressed as part of the broader overview.

Why Your ₹18 LPA Offer Translates to ₹1.1L Monthly Take-Home

Many Indian tech professionals are surprised to find their monthly salary significantly lower than their CTC divided by 12, a gap explained by how Cost to Company is structured. CTC includes employer PF contributions, gratuity accruals, and variable pay that never appear as monthly cash in hand. Further deductions such as the employee's own EPF share, professional tax, and income tax TDS reduce the gross amount further before it reaches a bank account. For FY 2025-26, the new tax regime is the default and often favours salaried employees who do not claim large exemptions, though individuals with high rent, home loans, or maxed 80C investments may still benefit from the old regime. A developer who experienced this pay gap firsthand built a browser-based take-home salary calculator for India that compares both tax regimes side by side without requiring a sign-up.

SQL Interviews Test Business Thinking, Not Just Syntax, Experts Say

A guide published by Four-Leaf AI argues that SQL interview rounds primarily evaluate a candidate's ability to translate vague business questions into precise queries, rather than test raw syntax knowledge. Interviewers deliberately leave prompts underspecified to see whether candidates clarify requirements before writing any code, a habit they consider more valuable than the query itself. The article identifies three question types that dominate most SQL rounds: join-and-aggregation, window functions, and open-ended business analysis against an unfamiliar schema. Strong candidates are distinguished by how they handle edge cases such as nulls, duplicate rows, and ambiguous definitions like 'active user.' The emphasis on SQL preparation is underscored by the Stack Overflow 2025 Developer Survey, which found 58.6% of developers used SQL in the past year, ranking it the third most-used language globally.
