myisam_ftdump displays information about
FULLTEXT indexes in
MyISAM tables. It reads the
MyISAM index file directly, so it must be
run on the server host where the table is located
Invoke myisam_ftdump like this:
tbl_name argument should be the
name of a
MyISAM table. You can also
specify a table by naming its index file (the file with the
.MYI suffix). If you do not invoke
myisam_ftdump in the directory where the
table files are located, the table or index file name name
must be preceded by the pathname to the table's database
directory. Index numbers begin with 0.
Example: Suppose that the
contains a table named
has the following definition:
CREATE TABLE mytexttable ( id INT NOT NULL, txt TEXT NOT NULL, PRIMARY KEY (id), FULLTEXT (txt) );
The index on
id is index 0 and the
FULLTEXT index on
index 1. If your working directory is the
test database directory, invoke
myisam_ftdump as follows:
myisam_ftdump mytexttable 1
If the pathname to the
you can also specify the table name argument using that
pathname. This is useful if you do not invoke
myisam_ftdump in the database directory:
myisam_ftdump /usr/local/mysql/data/test/mytexttable 1
myisam_ftdump understands the following options:
Display a help message and exit.
Calculate per-word statistics (counts and global weights).
Dump the index, including data offsets and word weights.
Report the length distribution.
Report global index statistics. This is the default operation if no other operation is specified.
Verbose mode. Print more output about what the program does.
