你可以使用动态SQL来进行动态透视，例如
SET @sql = NULL;
SET @date = '2020-11-30';
SELECT GROUP_CONCAT(
CONCAT(
'SUM(CASE WHEN Partners = "', Partners,'" THEN Amount ELSE 0 END ) AS'
,Partners
)
)
INTO @sql
FROM ( SELECT DISTINCT Partners FROM BPFinal WHERE Date = @date ) AS b;
SET @sql = CONCAT('SELECT Branch,',@sql,
' FROM BPFinal
WHERE Date = "',@date,'"'
' GROUP BY Branch');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

您是否在MySQL中使用了一些查询来做一些枢轴操作？
非常感谢你的帮助
