Sqlite: how to count words in a field

Assuming a table like this:

create table test (id integer primary key autoincrement, name text);

and values like:

insert into test values (null, "test") ;
insert into test values (null, "word1 word2 word3")  ;
insert into test values (null, "word4 word5 word6")  ;
insert into test values (null, "word7 word8 word9 word10 word11 word11")  ;

here is the result:

select id, name from test

1;test
2;word1 word2 word3
3;word4 word5 word6
4;word7 word8 word9 word10 word11 word12

Counting

Now you want to count the word(s) in the field "name" - here is how to proceed:
select (length(name)-length(replace(name," ","")))+1 as wordcount, name from test

it works because the query is looking for the number of space - a space means a new word is in the field and that is why you need to add 1 to the total.

Sqlite is awesome
