[英]How to count the number of occurrences of a particular word in a MySQL blob text?
I have stored the contents of a text file in a MySQL table as a blob. 我已经将文本文件的内容作为Blob存储在MySQL表中。 I want to count the number of occurrences of a particular word from that text.
我想计算该文本中某个特定单词出现的次数。
Is there any way I can do that? 有什么办法可以做到吗?
Try this 尝试这个
SET @searchthis="lumia";
SELECT CAST((LENGTH(`documents`.`file`) -
LENGTH(REPLACE(`documents`.`file`, @searchthis, ""))) /
LENGTH(@searchthis) AS UNSIGNED
) AS searchthis_count
FROM documents ;
