Question

运行mysql查询时出现错误。

INSERT INTO raw_table_200(entity_id, master_attribute_id, attribute_value, history_schedule_id, parent_id)
VALUES
((SELECT entity_id FROM raw_table_200 WHERE master_attribute_id = 37),38,(SELECT SUBSTRING_INDEX(attribute_value,' ',-1) FROM raw_table_200 WHERE master_attribute_id=29),223,(SELECT raw_id FROM raw_table_200 WHERE master_attribute_id=31));

================================================ ==========

由mysql服务器发出的错误提示

"You can't specify target table 'raw_table_200' for update in FROM clause"

Answer 1

如果您无法选择并在同一张表中插入，请尝试以此方式强制构建temo表

INSERT INTO raw_table_200 (entity_id, master_attribute_id, attribute_value, history_schedule_id, parent_id)
select * from (
    ((SELECT entity_id 
        FROM raw_table_200 WHERE master_attribute_id = 37)
        ,38
        , (SELECT SUBSTRING_INDEX(attribute_value,' ',-1) 
        FROM raw_table_200 WHERE master_attribute_id=29)
        ,223
        , (SELECT raw_id FROM raw_table_200 WHERE master_attribute_id=31));
)  T
