php - How can I filter a MySQL result by the amount of words in a column? -

-

I am trying to filter the results of a MySQL query with the number of words within a table column.

For example, there are 10 testimonials with my column ID, name, URL, testimonials, and five of those lines have a testimonial column with more than 100 words to create a certificate.

How do I use a query to return only those testimonials columns that are less than 100 words?

It's not that the way I did it, it's very Large, but ... 

  SELECT * FROM table WHERE LENGTH (field) - LENGTH (Ripley (field, '', '')) + 1 & Lt; 100   
 It actually counts the spaces ... but it can be enough for you.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.
