string match with in database

i have database having more then 2000 rows which contains strings like

(for eg-Teach the children not to receive anything for nothing; let them earn by hardwork the things they seek.)

and i have editfield and a button now what i want is when the user enter any word to edit field,
it will match that word with all the strings ,if the match is found that will return all the strings that having the enterd word
for eg- i have enter 'Teach' in the edit fied and click to the search button that will match with my strings in my DataBase
and it will show me all the strings having that word.

Re: string match with in database

Simon is suggesting that you can do this with SQL commands.  Here is a sample - this has been heavily edited so will probably not run, but does give you all the processing.


Look at the SQLiteDemo for more.


            String dataBaseLocation = ...;
            URI myURI = URI.create(dataBaseLocation);
            d = DatabaseFactory.open(myURI);
            String SQLSelect = "SELECT description, url, title " +
                               "FROM Book" + tableName + ' ' +
                               "WHERE title LIKE '%" + keyWord + "%' " +
                               "LIMIT " + limit;
            Statement st = d.createStatement(SQLSelect);
            c = st.getCursor();
            Row r;
            long rowCount = 0;
            // Extract details from each row returned. 
            while ( c.next() ) {
                r = c.getRow();
                String description = r.getString(0);
                String link = r.getString(1);
                String title = r.getString(2);
                // add to a colledction to be displayed on screen.
