从内部联接结果中删除单个表中的数据

Question

我在mysql中有此查询。

SELECT
    a.*, b.material_tools_group
FROM
    borrowing_mat_master_data AS a
INNER JOIN material_tools_master_data AS b ON a.tools_code = b.material_code
WHERE
    material_tools_group IN (
        'Consumable',
        'Material'
    )
ORDER BY
    `a`.`tools_code` ASC

我想从上面的查询中删除结果，我已经在下面尝试过此查询，但是它不起作用。

DELETE
FROM
    borrowing_mat_master_data
WHERE
    tools_code IN (
        SELECT
            a.*, b.material_tools_group
        FROM
            borrowing_mat_master_data AS a
        INNER JOIN material_tools_master_data AS b ON a.tools_code = b.material_code
        WHERE
            material_tools_group IN (
                'Consumable',
                'Material'
            )
    );

任何帮助都感激不尽。

问候。

为了从borrowing_mat_master_data结果中删除borrowing_mat_master_data表中的数据：

DELETE a
FROM
    borrowing_mat_master_data AS a
INNER JOIN material_tools_master_data AS b ON a.tools_code = b.material_code
WHERE
    material_tools_group IN (
        'Consumable',
        'Material'
    );

为了从borrowing_mat_master_data结果中同时删除borrowing_mat_master_data和material_tools_master_data表中的数据：

DELETE a,b
FROM
    borrowing_mat_master_data AS a
INNER JOIN material_tools_master_data AS b ON a.tools_code = b.material_code
WHERE
    material_tools_group IN (
        'Consumable',
        'Material'
    )

如果你想删除表格的表名borrowing_mat_master_data的整个记录，并只material_tools_group以下查询表名material_tools_master_data使用专栏中，我希望它会帮助你。

DELETE a FROM borrowing_mat_master_data AS a
INNER JOIN material_tools_master_data AS b ON a.tools_code = b.material_code
WHERE
    b.material_tools_group IN (
        'Consumable',
        'Material'
    )
