4       23       here in Australia its chilly season
5       74       hey sam whats the plan for tomorrow

see id is auto-increment.from column says which user is sending message and the message column consists of messages . i want to know which users has sent how many words .so i have to first count the words from row then i have to search the entire column and find where there is repetiotion and add the words for that particular user.in my example you can see that two places from 23 and 74 is coming. i want my output as

    from       nos
    23         10
    65         4 
    74         12

here you can see that 23 is coming in two rows so i have added the no of words of two rows like that 74 is also coming in two rows .please guide

Answer 1

You can count words by this query-

Select length('string')-length(replace('string',' ',''))+1;

For your table you can do it as

Select *,(length(message)-length(replace(message,' ',''))+1) from table_name

This will display word count of every msg in fron of it.

For your desired result, try this-

Select `from`, sum((length(message)-length(replace(message,' ',''))+1)) as nos from table_name group by `from`
