我正在使用Configure.It上的api builder创建API .任何人都可以解释我如何在api块中使用php自定义函数.

目前我正在使用此查询,是否有任何替代此查询,这将更快地工作.

SELECT 
    SUM(result1),
    SUM(result2),
    SUM(result3)
FROM (
    (
        SELECT 
            0 as result1,0 as result2,COUNT(*) as result3
        FROM 
            table1
    )
    UNION
    (
        SELECT 
            count(*) as result1,0 as result2,0 as result3
        FROM 
         table2
    )
    UNION
    (
        SELECT 
            0 as result1,count(*) as result2,0 as result3
        FROM 
            table3
    )
    ) as allresult
