Cassandra + 数据插入 + set<FROZEN<map<text,text>>>
Cassandra + data insertion + set<FROZEN<map<text,text>>>
我的列族结构是:
create table mykeyspc."test" (
id int PRIMARY KEY,
val set<frozen<map<text,text>>>
);
当我通过 CQL 插入数据时 shell
insert into "test" JSON '{"id":1,"val":{"ab","bc"}}';
Error: INVALIDREQUEST: code=2200 [Invalid query] message="Counld not decode JSon string as
map:org.codehaus.jackson.jsonParseException: Unexpected character{'{'{ code 123})
或
insert into "test" (id,val) values (1,{{'ab','bc'},{'sdf','name'}});
Error: INVALIDREQUEST: code=2200 [Invalid query] message="INVALID SET LITERAL FOR
VAL:value{'a','b'} is not of type frozen<map<text,text>>"
在您的第二个示例中,尝试使用冒号 :
而不是逗号分隔地图 key/values。
aploetz@cqlsh:Whosebug> INSERT INTO mapOfSet (id,val)
VALUES (1,{{'ab':'bc'},{'sdf':'name'}});
aploetz@cqlsh:Whosebug> SELECT * FROm mapofset WHERE id=1;
id | val
----+---------------------------------
1 | {{'ab': 'bc'}, {'sdf': 'name'}}
