检查字段是否包含特定值

Question

我有一个表 project_info ，我想检查特定项目（例如project_id = 1 ）是否具有状态 0 ，至少有一个start_date是＆lt; =今天的日期。

project_info

if(above logic is true){
//do somthing
}
else{
   do nothing
}

我如何在mysql中执行此操作？

    SELECT DISTINCT project_id from project_info where 
         status field (contain all 0 
         with no 1,loop through the whole table for project_id =1) 
          and start_date(at least one start_date <=curdate)

Answer 1

我认为这些SQL对你有用。

select * from project_info where project_id >=1  and status =0  and
    start_date <= CURDATE()

谢谢。
