（psycopg2.ProgrammingError）缺少表“ t”的FROM子句条目

Question

尝试使用postgres从t插入表s时出现错误，

INSERT INTO s (name, site_square_footage)
SELECT name, site_square_footage
FROM temp_sites AS t
ON CONFLICT (name)
    DO UPDATE SET 
        site_square_footage = t.site_sqaure_footage

请帮助，谢谢！

Answer 1

我通过参考postgres文档找出答案，语法有点奇怪。

INSERT INTO s (name, site_square_footage)
SELECT name, site_square_footage
FROM temp_sites AS t
ON CONFLICT (name)
    DO UPDATE SET 
        site_square_footage = excluded.site_sqaure_footage
