release of Webyog's flagship product, SQLyog Enterprise
version 4.1, a new ODBC "Power Tool" is introduced that replaces the
old "ODBC import tool." Starting with SQLyog version 4.2 it was
re-named "SQLyog Migration Tool," so this is the term that I will use
in this text. This is not just a new name for something old that comes in
a new bottle--the Migration Tool has been completely rewritten. It is all
completely new code, but more important to users it offers a wide range of
new possibilities. The term "ODBC-import" to me means, "Fetching
some external data into MySQL." "Migration" is much more
than that it imports not only data but also indexes ("ordinary"
indexes, Primary Keys, Foreign Keys all that used to be called
"metadata"), and it provides a large set of options for (almost) any
equally well fit for use with a Migration Process considered as a one-time
event (no matter how long that process might take!) and in situations with
"permanent coexistence" (or "permanent migration" if you
like) of more database systems within an organisation.
opinion the SQLyog ODBC-import tool is the most complete, versatile, intuitive
and flexible import tool that exists and that you can imagine. All the options,
that the tool offers, are available from the SQLyog GUI. There is no need to
edit some 'strange format' file to transform or filter data during import. It
lets you easily import any subset ("vertically" or
"horizontally") of data and metadata (all sorts of indexes). It can
be scheduled, run from external applications, and run in batch-mode in
combination with any other OS/system command, executable file and any other job
type of the SQLyog Job Agent (SJA). The other job types offered by the
SJA are, MySQL to MySQL synchronization, High Performance Scheduled Backups and
"Notifications Service" the last one is a very unique facility that
lets you schedule and execute any SQL with your databases and have formatted
result-sets of these queries delivered to your mailbox.
XML-format of the job file control lets you integrate the full functionality of
the ODBC-import tool (and any other job type of the SJA) into your own applications,
if that is what you want.
If all of
that talk is nonsense to you, you can simply use Migration Tool from the SQLyog
GUI, and it is almost as simple as using an Office-suite application. The
wizards will guide you so you will not have to worry about what a complicated
thing you actually are doing!
developed terrifically over that last year or so, and it continues to do
so. Before this article is out you will probably see that full support
for MySQL version 5 features (Stored Procedures, Triggers and Views) is
available, and in just a few weeks more you will have localised versions.
Check the Webyog website frequently at www.webyog.com.
Moreover, do not forget that the Migration Tool is only a "small
corner" (though big in itself!) of the complete set of functionalities you
will find in SQLyog Enterprise. I recommend that you download the fully
functional demo of SQLyog Enterprise from www.webyog.com
if you do not have it, so that you can experiment with it on your own
system. This article should give you ideas enough for many hours of
experimenting and testing for yourself.
