Access a MySQL database

(with mym.m)

The submission collects several small utilities 'wrapping' Yannick Maret's 'mym' Matlab/MySQL interface, available from
http://sourceforge.net/projects/mym

Their application is illustrated by script mydemo.m, which uses the FEX download data presented in FEX submission 'A week on File Exchange'. First, we read the data (6 mixed-type columns, over 1 million rows) from a text file into a MySQL table, using 'load infile', passed through the basic mym interface. Next, we retrieve the table's structure and contents into Matlab workspace using TBATTR and TBREAD, and take the data back to MySQL with TBWRITE.

We observe that text-file-mediated exchange, accommodated on MySQL's side by 'load infile' and 'select into outfile', is a vastly superior option for large datasets; TBREAD and TBWRITE (the latter operating through multiple-row 'insert values' flushes) are more convenient for small datasets with many columns.
