我試圖從pg_stats_activity獲取當前查詢,但未按預期工作。 外交易一切正常: pagetest=# select query from pg_stat_activity where pid = pg_backend_pid() and 1 is not null;
query

我有一個表lawyers: CREATE TABLE lawyers (
id SERIAL PRIMARY KEY,
name VARCHAR,
name_url VARCHAR,
pic_url VARCHAR(200)
);
想象整個表看起來像這樣: 而且表格爲firms: CREATE TABLE firms (
id SERIAL PR
我已經遇到了一些「複雜」的查詢,如: with q1 as (
select w.entity_id, p.actionable_group, p.error_type
from issue_analysis p
join log l on p.id = l.issue_analysis_id
join website w on l.website_id = w.id
where l.da
我試圖選擇所有的實體,即使它們不是匹配表達式,但是這個只返回'true'值。 SELECT entity_id, regexp_matches(error_params, '"select_flight"') IS NOT NULL
FROM MyTable
GROUP BY 1
有沒有辦法做解決內部SELECT語句或在這種情況下,我們應該使用LEFT JOIN表與regexp_match
