MYSQL -拆分字符串"Lurex Cotton Squadrato“并返回最后一个单词

Question

我的表中有几行，我想将最后一个单词从一列导出到新列中。

只需要从这个字符串中拆分出最后一个单词，不知道怎么做……

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

这只是一个猜测，任何函数都可以。MYSQL 5.

以下是我的数据集的一个示例：

|| *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 ||  ||  ||  ||  ||  ||

Answer 1

SUBSTRING_INDEX是正确的函数：

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

Answer 2

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

Answer 3

您可以使用substring_index()函数。

示例

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

将其应用于update子句。
