我试图在Postgres 9.1.3中使用这个查询:
WITH stops AS (
SELECT citation_id,
rank() OVER (ORDER BY offense_timestamp,
defendant_dl,
offense_street_number,
offense_street_name) AS stop
FROM consistent.master
WHERE citing_jurisdiction=1
)
UPDATE consistent.master
SET arrest_id = stops.stop
WHERE citing_jurisdiction=1
AND stops.citation_id = consistent.master.citation_id;
我得到了这个错误:
ERROR: missing FROM-clause entry for table "stops"
LINE 12: SET arrest_id = stops.stop
^
********** Error **********
ERROR: missing FROM-clause entry for table "stops"
SQL state: 42P01
Character: 280
我真的很困惑.根据Postgres文档,WITH子句看起来是正确的.如果我在WITH子句中单独运行查询,我会得到正确的结果.
