＆＃34;列引用含糊不清或重复的名称＆＃34;在Apache Phoenix上使用别名时

Question

将Apache Phoenix 4.6.0用于HBase 1.1.2。

我有一个像这样创建的简单表：

CREATE TABLE "events" (
"uuid" VARCHAR(64) PRIMARY KEY,
"event"."session" VARCHAR(64),
"event"."name" VARCHAR(32),
"event"."date" UNSIGNED_DATE,
"product"."name" VARCHAR(32),
"data"."*" VARCHAR(64)
) default_column_family='event', IMMUTABLE_ROWS=true

这些查询有效：

SELECT COUNT(*) FROM "events" AS search WHERE search."event"."name" = 'search'

SELECT COUNT(*) FROM 
(SELECT click."event"."session" 
FROM "events" AS click WHERE "event"."name" = 'click')

但这不是：

SELECT COUNT(*) FROM "events" AS search 
WHERE search."event"."name" = 'search' 
AND search."event"."session" NOT IN (SELECT click."event"."session" 
FROM "events" AS click 
WHERE click."event"."name" = 'click');

  

错误：错误502（42702）：列引用不明确或重复   名。 columnName = name SQLState：42702 ErrorCode：502

为什么？

尝试count(1)对不起作用的人$variable = 'x'; $query = $this->db->query(" SELECT... FROM... WHERE some_column = '$variable' "); return $query->result_array(); 。你清楚地对表格进行别名处理，但是背景中可能会有一些没有使用别名的星号。
