PHP MySql Where Field = <4个单词

Question

I need to use a query which will pull data from a field when it is less then 4 words, is this possible and if so could you give some pointers? I suppose if not possible it could cycle through the results until it found one which was 3 words and then end the while statement when it has found one.

Answer 1

SELECT column FROM table where LENGTH(column) - LENGTH(REPLACE(column, ' ', ''))+1 < 4
