Want to add VERY IMP point regarding the count() function.... Using count(*) gives the total number of rows in a table, while count(column_name) counts only the rows where the specified column has a non-null value. If you use count(column_name), it may not accurately reflect the total number of rows because it ignores null values in that column. So, be careful when using count(column_name) as it might give a wrong count if there are null values in that column.
