Sqlite 将数据从 temp table 复制到另一个有冲突
Sqlite copy data from temp table to another with conflict
我有主 table 和临时 table 的 db sqlite。我想从文本文件导入数据，然后我想将数据从 temp table 插入到 main table.
INSERT INTO table(key) SELECT src.key FROM temp as src
ON CONFLICT (table.key) DO UPDATE SET to_insert = 0, to_delete =0;
当我尝试 运行 这个查询时，sqlite 向我抛出这个错误。
Query 1 ERROR: near "DO": syntax error
是否可能从另一个 table 插入数据有冲突？
select 语句需要一个 where 子句：
insert into mytable(key)
select key from temp where true
on conflict (key) do update set to_insert = 0, to_delete =0;
这个陷阱被记录为 parsing ambiguity（强调我的）：
When the INSERT statement to which the UPSERT is attached takes its values from a SELECT statement, there is a potential parsing ambiguity. The parser might not be able to tell if the ON keyword is introducing the UPSERT or if it is the ON clause of a join. To work around this, the SELECT statement should always include a WHERE clause, even if that WHERE clause is just WHERE true.
