SELECT Material AS material Batch AS batch PostingDate AS postingDate quantityInEntryUnit AS quantityInEntryUnit QuantityInEntryUnit - ArtificialConsume - AutomaticConsume AS availableInventory Arti

上述SQL语句报错的原因是日期格式的问题。在将日期参数传递给DATE_FORMAT函数时，需要使用引号将日期字符串括起来。另外，日期字符串中的时间部分不是必需的，因此可以将时间部分去掉。

以下是修改后的SQL语句：

SELECT Material AS material, Batch AS batch, PostingDate AS postingDate, quantityInEntryUnit AS quantityInEntryUnit, ( QuantityInEntryUnit - ArtificialConsume - AutomaticConsume ) AS availableInventory, ArtificialConsume AS artificialConsume, SUM( QuantityInEntryUnit - ArtificialConsume - AutomaticConsume ) AS totalQuantity, AutomaticConsume AS automaticConsume FROM vmi_materialdocument WHERE DATE_FORMAT( PostingDate, '%Y-%m' ) = DATE_FORMAT( '2023-09-01', '%Y-%m' ) ORDER BY PostingDate ASC
