Fast MySQL import

How do I post following text file to the MySql database?

1apple    245red   12.5    
2banana   19 yellow25.4    
3pineapple789       1.0    
4orange      orange      
5banana   12 yellow 25

Data format is always same:

Primarykey ddddd (4 digits) name nnnnnnnnn (9 Chars); count ddd (3 digits); color nnnnnn (6 chars); dddd (4 digits with decimal)
Each record is terminated with an end-of-line character.

Looking for a command that will post above sample info
(actual sample.txt has appx 30.000 records, and it needs to be able to do this in few seconds

Text file name: sample.txt
Database name: fruits ; Username: Admin ; Password: pass
Tablenames: name; count; color; weight

(I have tried Navicat, but it takes 5 minutes to do the import)

if you can replace the text-file with a csv (comma seperatde value) file, you could use the mysqlimport tool. Can the generating application only handle fixed-length strucures ?

I've just found this...
http://theoryx5.uwinnipeg.ca/CPAN/data/Text-FixedLength-Extra/Extra.html

Whatever method gets this done in few secs, i'll accept.
Perl/mysql/php......

the issue here is the size 1 meg file with 30.000 records. I need to update it, since the file will change every minute (Its actually mod from stock program, but need this to be solved)
real data has 15 fields with 70 chars of data...
Thanks

The mysqlimport tool that bagger99 mentioned is a command-line interface to LOAD DATA INFILE SQL statement.  It doesn't handle fixed-width columns per se, but your file might work anyway.  Or, you could use sed or awk to add the delimiters and pipe the output to mysqlimport.

Ok would these solutions be able to do all of this in few secs? 30.000 lines of data... I doubt.

Looking for a full solution for this.

Trying to increase point value...

This is actually extremely easy, when you do not specify FIELDS ENCLOSED BY or FIELDS SEPERATED BY in a LOAD DATA statement you get a fixed width handler.

Quoted from http://www.mysql.com/doc/en/LOAD_DATA.html:

If the FIELDS TERMINATED BY and FIELDS ENCLOSED BY values are both empty (''), a fixed-row (non-delimited) format is used. With fixed-row format, no delimiters are used between fields (but you can still have a line terminator). Instead, column values are written and read using the ``display'' widths of the columns. For example, if a column is declared as INT(7), values for the column are written using 7-character fields. On input, values for the column are obtained by reading 7 characters. LINES TERMINATED BY is still used to separate lines. If a line doesn't contain all fields, the rest of the fields will be set to their default values. If you don't have a line terminator, you should set this to ''. In this case the text file must contain all fields for each row. Fixed-row format also affects handling of NULL values; see below. Note that fixed-size format will not work if you are using a multi-byte character set.

So... Simple create a table defined the same as your fixed width file and perform LOAD DATA

Primarykey ddddd (4 digits) name nnnnnnnnn (9 Chars); count ddd (3 digits); color nnnnnn (6 chars); dddd (4 digits with decimal)

CREATE TABLE loader
(
      id INT(4) NOT NULL PRIMARY KEY,
      name CHAR(4),
      count INT(3),
      color CHAR(6),
      decval DECIMAL(4,2)
);

LOAD DATA INFILE '/path/to/sample.txt'
INTO TABLE tablename
FIELDS TERMINATED BY ''
ENCLOSED BY ''
LINES TERMINATED BY '\n';
