实际上我将两个多表数据插入到一个表中，我编写了以下查询，我想将两个表中的一些字段插入到新表中。我为我的网站新提交的表单编写了代码，但我想更新数据库中的现有数据。
请看下面的qyery。 请提出建议。
下面的查询给我一个错误:
“操作数应包含 1 列”
INSERT INTO am_intranet_hr_lead_document(doc_name,careers_submissions_key,hr_phase_key,response_id,date_added)
SELECT (am_career_submissions.resume,am_career_submissions.careers_submissions_key,am_intranet_hr_lead_response.hr_phase_key,am_intranet_hr_lead_response.response_id,am_career_submissions.add_dt)
FROM am_career_submissions, am_intranet_hr_lead_response
WHERE am_career_submissions.careers_submissions_key = am_intranet_hr_lead_response.careers_submissions_key
谢谢。
最佳答案
使用内连接和限制
像这样
INSERT INTO am_intranet_hr_lead_document(doc_name,careers_submissions_key,hr_phase_key,response_id,date_added)
SELECT (am_career_submissions.resume,am_career_submissions.careers_submissions_key,am_intranet_hr_lead_response.hr_phase_key,am_intranet_hr_lead_response.response_id,am_career_submissions.add_dt)
FROM am_career_submissions,
join am_intranet_hr_lead_response
on am_career_submissions.careers_submissions_key = am_intranet_hr_lead_response.careers_submissions_key
limit 1
关于php - 操作数应包含 1 列用于多表查询，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45456967/
