If you wondered where I went.. I was onboarding a new client onto our POS system. Turns out real queries pay better than X threads. Back now 😄 Please Show #theSQLQuerycoach around

Every organisation needs people who understand data. SQL gives you that superpower. #CareerGrowth #LearnSQL #TheSQLQueryCoach https://t.co/D9H9HLk5y4

Never trust data blindly. Always check for NULLs, duplicates, and weird values. SQL teaches you to think critically. #SQL #DataCleaning #Analytics #TheSQLQueryCoach https://t.co/D9H9HLk5y4

SQL is the gateway to Data Science. If you can extract clean data, models become easier. #DataScienceJourney #SQLPower #TheSQLQueryCoach

Your data science journey starts with “SELECT * FROM table”. Don’t underestimate the small steps. #DataScience #SQLBeginners #TechUganda #TheSQLQueryCoach https://t.co/D9H9HLjxIw

A good SQL query answers a business question, not just returns rows. Think beyond code. Think value. #BusinessIntelligence #SQLThinking #TheSQLQueryCoach

If your query feels long, break it into CTEs. Readable > fancy. #CTE #SQLStyle #DataEngineering #TheSQLQueryCoach

Normalize your data, but not too much. Balance matters. Good databases are practical, not perfect. #DatabaseDesign #SQLArchitecture #TheSQLQueryCoach

Indexes are like the table of contents of a book. They help SQL find data faster. Use them wisely. #DatabaseDesign #SQLPerformance #TheSQLQueryCoach

Always write readable SQL. Future-you will thank past-you. Indent. Space. Comment. #CleanCode #SQLBestPractices #TheSQLQueryCoach https://t.co/D9H9HLk5y4

Filtering isn’t enough. Master WHERE + HAVING. One filters rows, the other filters aggregates. #SQLLogic #TechLearning #TheSQLQueryCoach https://t.co/D9H9HLjxIw

COUNT(*) tells you how many rows exist. COUNT(column) tells you how many values are NOT null. Simple but important. #SQLTips #DataQuality #TheSQLQueryCoach

Don’t fear errors in SQL. Every “syntax error” is a lesson pushing you toward mastery. #CodingLife #SQLJourney #TechMotivation #TheSQLQueryCoach

You don’t need to master everything today. SQL is a journey — one query at a time. #Motivation #SQLLearning #TheSQLQueryCoach https://t.co/D9H9HLk5y4

LEFT JOIN is the most used JOIN in analytics. It preserves your main dataset. #SQLJoins #DataAnalysis #TheSQLQueryCoach

Before writing a complex query, ask: “What question am I really trying to answer?” Clarity reduces errors. #SQLMindset #DataScienceTips #Coding #TheSQLQueryCoach

Every data analyst should learn: • SELECT • GROUP BY • HAVING • JOIN • SUM() • COUNT() These 6 make you unstoppable. #Analytics #SQLFundamentals #DataSkills #TheSQLQueryCoach

Pro tip: Always know your PRIMARY KEY before writing any JOIN. It’s the anchor of your data. #SQLJoins #DataManagement #ProgrammingTips https://t.co/D9H9HLk5y4 #TheSQLQueryCoach

SQL JOINs are not hard they’re just relationships: INNER = matching data LEFT = include all from left table RIGHT = include all from right #SQL #JoinsExplained #DataCareer #TheSQLQueryCoach

@SumitM_X This is a classic use case for GROUP BY + HAVING. Group by Score and filter scores that appear more than once, then join back (or use a subquery) to return the student names. Simple question, but it tests real understanding of duplicates and aggregation. im #theSQLQueryCoach
