A documentation for the MySQL and iODBC table driver is contained in:
ftp://glpk.dyndns.org/glpk/tables.txt
Examples can be downloaded from
ftp://glpk.dyndns.org/glpk/sql_examples.tar.gz
or
ftp://87.230.79.59/glpk/sql_examples.tar.gz
Assuming MySQL is installed the examples can be set up as follows:
cd glpk-4.27/examples
wget ftp://glpk.dyndns.org/glpk/sql_examples.tar.gz
tar -xzf sql_examples.tar.gz
cd sql
./mysql_setup.sh
mysql_setup.sh does the following:
A database glpk is created.
A user glpk is created.
Tables for the examples are setup and filled.
To run the examples:
../glpsol -m transp_mysql.mod
../glpsol -m transp_odbc.mod
../glpsol -m sudoku_mysql.mod
../glpsol -m sudoku_odbc.mod
The examples are copies of transp.mod and sudoku.mod changed to import data
from the database and writing the results to the database.
Best regards
Xypron
