Question

对于每个function palindrome(str) { return str.split(‘’).every((char, i) => { return char === str[str.length - i - 1]; }); }，几行中都会出现几个名称。如何使它们全部显示在一行中？

ids

意外结果：

select 
      cli.client, stb.macaddres, stb.unica as card, 
      pro.name 
from 
      clientes cli
inner join boxes stb on stb.nuclient = cli.nuclient
inner join date.servicio ser on ser.ids = stb.ids
inner join date.producto pro on pro.proid = ser.serid
where 
      cli.client=7;

所需结果：

client macaddress  única  name
7       xxxxxxxxx  56565 product1
7       xxxxxxxxx  56565 product2
7       xxxxxxxxx  56565 product3

Answer 1

您可以按照戈登在评论中所说的listagg()进行操作，您可以在此处阅读有关文档ListAGG()的信息

对于您的查询：

select 
     cli.client, stb.macaddres, stb.unica as card 
     LISTAGG(pro.name, ', ') WITHIN GROUP (ORDER BY pro.proid ASC) "Name"
from 
     clientes cli
inner join boxes stb on stb.nuclient = cli.nuclient
inner join date.servicio ser on ser.ids = stb.ids
inner join date.producto pro on pro.proid = ser.serid
where 
     cli.client = 7;
Group By
    cli.client, stb.macaddres, stb.unica

统一多个SQL行
