By default, every row in SQLite has a special column, usually called the "rowid", that uniquely identifies that row within the table.

R-32341-39358-46818-14772-56147-53577-21121-58224 tcl slt th3 src
However if the phrase "WITHOUT ROWID" is added to the end of a CREATE TABLE statement, then the special "rowid" column is omitted.

R-00217-01605-34207-18386-37017-37707-31164-60184 tcl slt th3 src
To create a WITHOUT ROWID table, simply add the keywords "WITHOUT ROWID" to the end of the CREATE TABLE statement. For example:
CREATE TABLE IF NOT EXISTS wordcount( word TEXT PRIMARY KEY, cnt INTEGER ) WITHOUT ROWID;

R-24770-17719-20723-28193-15704-54316-24358-11027 tcl slt th3 src
As with all SQL syntax, the case of the keywords does not matter. One can write "WITHOUT rowid" or "without rowid" or "WiThOuT rOwId" and it will mean the same thing.
