MYSQL - 拆分字符串“Lurex Cotton Squadrato”并返回最后一个字

我的表中有好几行，我想将最后一个字从一列导出到新列中。MYSQL - 拆分字符串“Lurex Cotton Squadrato”并返回最后一个字

仅仅需要从这个字符串分割出来的最后一个字，不能工作了怎么办呢？

UPDATE sc_module_template_slideshows_images 
SET image_title = RIGHT(image_name, ?????)

这只是一个猜测，任何函数会做。 MYSQL 5.

这里是我的数据集的例子：

|| *slideshow_id* || *image_id* || *image_active* || *image_order* || *image_name* || *image_source* || *image_link* || *image_logo* || *image_title* || *image_presented* || *image_position* || 
|| 1 || 1 || 1 || 1 || Lurex Cotton Lappato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Cotton Lappato.jpg || || || || || || 
|| 1 || 2 || 1 || 2 || Lurex Cotton Squadrato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Cotton Squadrato.jpg || || || || || || 
|| 2 || 3 || 1 || 3 || Lurex Flax Lappato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Flax Lappato.jpg || || || || || || 
|| 2 || 4 || 1 || 4 || Lurex Flax Squadrato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Flax Squadrato.jpg || || || || || || 
|| 3 || 5 || 1 || 5 || Lurex Lame Lappato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex lame Lappato.jpg || || || || || || 
|| 3 || 6 || 1 || 6 || Lurex Lame Squadrato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Lame Squadrato.jpg || || || || || || 
|| 4 || 7 || 1 || 7 || Lurex Modal Lappato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Modal Lappato.jpg || || || || || || 
|| 4 || 8 || 1 || 8 || Lurex Modal Squadrato || media/products/Porcelain/Collections/Lurex/Swatches/Lurex Modal Squadrato.jpg || || || || || ||

SUBSTRING_INDEX是正确的函数：

SET image_title = SUBSTRING_INDEX(image_name,' ',-1)

+1，因为它看起来像它去了我的另一种方式。 – 2011-02-28 02:36:27

您可以使用SUBSTRING_INDEX（）函数。

例

select substring_index('Lurex Cotton Lappato',' ',-1); -- Lappato

应用它来更新子句。
