Editor to share with you how to achieve the alternative to ROLLUP in MySQL, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

After extracting the data from MySQL and using ROLLUP statistics, you want to add the project name to the left column of the data and use SQL

Sql code

SELECT (CASE WHEN ISNULL (PLAYERNO) THEN PLAYERNO=TOTAL ELSE PLAYERNO END) AS PLAYERNO,SUM (AMOUNT) FROM penalties

GROUP BY PLAYERNO WITH ROLLUP

The result is:

Like this

+-+ +

| | PLAYERNO | SUM (AMOUNT) |

+-+ +

| | 6 | 100.00 | |

| | 8 | 25.00 |

| | 27 | 175.00 | |

| | 44 | 130.00 | |

| | 104 | 50.00 |

| | NULL | 480.00 | |

+-+ +

6 rows in set, 1 warning (0.00 sec)

Displayed as a null value, modified as follows:

Sql code

SELECT PLAYERNO,SUM (AMOUNT) FROM penalties

GROUP BY PLAYERNO

UNION

SELECT TOTAL,SUM (AMOUNT)

FROM penalties

Display the results:

+-+ +

| | PLAYERNO | SUM (AMOUNT) |

+-+ +

| | 6 | 100.00 | |

| | 8 | 25.00 |

| | 27 | 175.00 | |
