Group By Clause in MySQL|| MySQL Tutorial || Code With Neha

On my previous video of mysql series I have discussed about count,avg and sum aggregate functions in mysql You can check the video from the above I button Today's we will be discussing about group by clause in mysql The MySQL GROUP BY Statement The GROUP BY statement groups rows that have the same values into summary rows, like "find the number of customers in each country". The GROUP BY statement is often used with aggregate functions (COUNT(), MAX(), MIN(), SUM(), AVG()) to group the result-set by one or more columns. GROUP BY Syntax SELECT column_name(s) FROM table_name WHERE condition GROUP BY column_name(s) GROUP BY Syntax using ORDER BY Clause SELECT column_name(s) FROM table_name WHERE condition GROUP BY column_name(s) ORDER BY column_name(s); Let us see with examples Today I will be using CUSTOMERS_DETAILS table under order_info database 1st example Query to group the table with ID and age SELECT ID,AGE FROM CUSTOMERS_DETAILS GROUP BY AGE; Example 2:- Query to group customers based on their age SELECT COUNT(ID),AGE FROM CUSTOMERS_DETAILS GROUP BY AGE; HERE WE NEED TO CATEGORIES CUSTOMERS WITH SIMILAR AGE GROUP SO WE ARE COUNTING THE NO OF CUSTOMERS WITH SIMILAR AGE Example 3:- QUERY TO GROUP CUSTOMERS BY THEIR AGE AND CALCULATE AVERAGE SALARY FOR EACH AGE SELECT COUNT(ID),AGE,AVG(SALARY) AS average_salary FROM CUSTOMERS_DETAILS GROUP BY AGE Example 4:- QUERY TO GROUP CUSTOMERS BY THEIR AGE AND CALCULATE TOTAL SALARY FOR EACH AGE SELECT COUNT(ID),SUM(SALARY),AGE FROM CUSTOMERS_DETAILS GROUP BY AGE Example 5:- QUERY TO GROUP CUSTOMERS BY THEIR AGE AND CALCULATE SALARY FOR EACH AGE WITH CONCATINATION SELECT CONCAT(AGE,'--',SALARY) AS salary_agewise FROM CUSTOMERS_DETAILS GROUP BY AGE,SALARY; Example 6:- QUERY TO FIND THE MAXIMUM SALARY FOR EACH AGE SELECT AGE,MAX(SALARY)AS max_salary FROM CUSTOMERS_DETAILS GROUP BY AGE ORDER BY SUM(SALARY)DESC; And that's all for today Hope you all will get some help from this video If it's so then don't forget to subscribe my channel Code with Neha and press the Bell Icon for Regular Updates See you in the next video till then Stay Safe Stay Happy #groupbyclause #groupbyclauseinsql #groupbyclauseinmysql #mysqlgroupbyclause #useofgroupbyclauseinmysql #clausesinsql #whatisgroupbyinsqlquery? #groupbyinsqlwithwherecondition #examplesofgroupbyclause #examplesofgroupbyclauseinmysql #sqltutorialsforbeginners #sqlgroupbytutorial #sqlgroupbyexamples #groupbyinsql #groupbyinmysql #mysqlgroupby #groupbystatementinmysql #learnmysql #mysqltutorial #mysqldatabase #mysqlcourse #mysqldatabasetutorial #mysqlcrashcourse #mysqltutorialforbeginners #sqlforbeginners #groupbyclausesyntax #sqlgroupby #sqltutorial #sqltutorialforbeginners #mysqltutorial #mysqltutorialforbeginners #mysql #mysqldatabase #coding
