我就是这么做的mysql Ver 14.14 Distrib 5.7.34, for Linux (x86_64) using EditLine wrapperKEY `composite` (`column1`, `column2`, `column3`)# BASH: for i in `seq 1 10000`; do mysqlKEY `composite` (`column1`, `column2`, `column3`)
) ENGINE=InnoDB
我有一个查询,它得到单位计数和它标记,如果完成与否。case when id is NULL then 'Not Started' else 'In Progress' end as Remarks,FROM tablecase when id is NULL then 'Not Started'
