解决方案：
1.将table转换为array
2.借助array_to_string将array进行拼接
示例:
--创建测试表 DROP TABLE IF EXISTS test; CREATE TEMP TABLE test("Id" int,"Name" varchar(100),"Type" int); INSERT INTO test("Id","Name","Type")VALUES(1,'NO1',1),(2,'NO2',2),(3,'NO3',2),(4,'NO4',2),(5,'NO5',3),(6,'NO6',3); --将结果转换为数组 --SELECT array(SELECT "Name" FROM test) --将数组合并为字符串 --select array_to_string(array[1,2,3], ',') --合并后的结果 --SELECT array_to_string(array(SELECT "Name" FROM test), ',') SELECT "Type" ,( array_to_string(array(SELECT "Name" FROM test as t WHERE t."Type" = test."Type" ) , ',') ) FROM test GROUP BY "Type";
DROP TABLE test;
