我在蜂巢的字符串列之一中有一个字符串"description=Qiemo|locationToolsID=733"
。当我尝试使用定界符|
(对于每个KV)和=
(对于键和值)将其转换为映射时,则不起作用。
具体来说,当我跑步时:
str_to_map(str('description=Qiemo|locationToolsID=733'),'|','=').
我期待中
description:Qiemo
locationToolsID:733
但是我越来越像这样
{"a":null,"":"","c":null,"d":null,"D":null,"e":null,"i":null,"I":null,"l":null,"m":null,"n":null,"o":null,"p":null,"Q":null,"r":null,"s":null,"3":null,"t":null,"T":null,"7":null,"|":null}
这是怎么回事?

您必须转义|
字符,因为它在Java正则表达式中具有特殊含义。
您可以尝试以下方法:
select str_to_map("description=Qiemo|locationToolsID=733",'\\\|','=');
OR
select str_to_map("description=Qiemo|locationToolsID=733",'[|]','=');
输出为:{"locationToolsID":"733","description":"Qiemo"}
