    Beginner mistake in SQL: Trying to learn everything at once. Better approach: Master one concept per day: Day 1: SELECT Day 2: WHERE Day 3: JOIN Day 4: GROUP BY Small wins = real progress. #SQLLearning

    💹 Learnt about Where Clause,Top and Orderby Clause and did a few querying with them. 📍 Top is used to specify the number of rows to be returned. 📍 Where clause are used to filter data. 📍Orderby clause is used to sort the results of a query either in Asc or Desc.

    Most of these data are stored in RDBMS, so the knowledge of SQL is very critical for Data Analysts and Scientists because it helps them filter data, retrieve data, modify data and clean data e.t.c from RDBMS #sql #sqllearning

    Day 29 of my data analytics journey📊. Practicing remains one of the best ways to truly learn. Today, I spent time applying some of the SQL syntaxes Mr @ezekiel_aleke has been teaching us, and each practice session felt like another step closer to the goal.

    Today, I dived into the wonderful world of SQL! 💻 Let me share with you some of the basics I learned about creating tables, inserting data, using select statements and operators, where statements and operators, and the powerful JOIN command. Oh, and we'll also touch on UNION! 👇

    1/ First things first, let's talk about creating tables in SQL. 🗂️ Tables are like spreadsheets that hold your data. You define the columns and their data types, and voila! You have a table ready to store your information. #SQLLearning
