/*
|
||||
** This C program extracts all "words" from an input document and adds them
|
||||
** to an SQLite database. A "word" is any contiguous sequence of alphabetic
|
||||
** characters. All digits, punctuation, and whitespace characters are
|
||||
** word separators. The database stores a single entry for each distinct
|
||||
** word together with a count of the number of occurrences of that word.
|
||||
** A fresh database is created automatically on each run.
|
||||
**
|
||||
** wordcount DATABASE INPUTFILE
|
||||
**
|
||||
** The INPUTFILE name can be omitted, in which case input it taken from
|
||||
** standard input.
|
||||
**
|
||||
** Option:
|
||||
**
|
||||
** --without-rowid Use a WITHOUT ROWID table to store the words.
|
||||
** --insert Use INSERT mode (the default)
|
||||
** --replace Use REPLACE mode
|
||||
** --select Use SELECT mode
|
||||
** --update Use UPDATE mode
|
||||
** --nocase Add the NOCASE collating sequence to the words.
|
||||
** --trace Enable sqlite3_trace() output.
|
||||
**
|
||||
** Modes:
|
||||
**
|
||||
** Insert mode means:
|
||||
** (1) INSERT OR IGNORE INTO wordcount VALUES($new,1)
|
||||
** (2) UPDATE wordcount SET cnt=cnt+1 WHERE word=$new -- if (1) is a noop
|
||||
**
|
||||
** Update mode means:
|
||||
** (1) INSERT OR IGNORE INTO wordcount VALUES($new,0)
|
||||
** (2) UPDATE wordcount SET cnt=cnt+1 WHERE word=$new
|
||||
**
|
||||
** Replace mode means:
|
||||
** (1) REPLACE INTO wordcount
|
||||
** VALUES($new,ifnull((SELECT cnt FROM wordcount WHERE word=$new),0)+1);
|
||||
**
|
||||
** Select mode modes:
|
||||
** (1) SELECT 1 FROM wordcount WHERE word=$newword
|
||||
** (2) INSERT INTO wordcount VALUES($new,1) -- if (1) returns nothing
|
||||
** (3) UPDATE wordcount SET cnt=cnt+1 WHERE word=$new --if (1) return TRUE
