  • Create a table student with fields student_id, name, date_of_birth, marks



  • Insert records into the table student



  • Update the marks of a student with student_id 101



  • Delete the record of a student with student_id 102



  • Select all records from the table student



  • Select records from the table student where marks are greater than 80



  • Select records from the table student where name starts with 'A'



  • Select records from the table student where date_of_birth is between '2000-01-01' and '2000-12-31'



  • Select records from the table student ordered by marks in descending order



  • Select records from the table student grouped by date_of_birth and calculate the average marks for each group



  • Select records from the table student joined with another table class on student_id



  • Use math functions such as POWER(), ROUND(), MOD() on data



  • Use text functions such as UCASE(), LCASE(), MID(), LENGTH(), LEFT(), RIGHT(), INSTR(), LTRIM(), RTRIM(), TRIM() on data
