tinyint(1) showing as bit?

If Java is showing you tinyint(1) as a boolean bitfield, that’s probably because MySQL recently changed the behavior of tinyint:

As of MySQL 5.0.3, a BIT data type is available for storing bit-field values. (Before 5.0.3, MySQL interprets BIT as TINYINT(1).) In MySQL 5.0.3, BIT is supported only for MyISAM. MySQL 5.0.5 extends BIT support to MEMORY, InnoDB, BDB, and NDBCLUSTER.

To convince your JDBC driver to show you tinyint for the tiny little int that it actually is, rather than as a boolean, try setting the tinyInt1isBit=false parameter when connecting.

The MySQL extension (php_mysql.dll) won’t load after upgrading PHP

Ugh. As usual, more weird problems while trying to upgrade PHP on a Windows box. Are we having fun yet?

If you find that the MySQL extension won’t load, then probably a previous PHP installer has placed a version of libmysql.dll somewhere else in your path. Look in c:\WINDOWS\system32\

The problem is almost certainly the reason for the following obscure comment

Although copying libmysql.dll to the Windows system directory also works (because the system directory is by default in the system’s PATH), it’s not recommended.

in the PHP MySQL documentation.

Make sure your home PHP directory is in your path, and that its finding libmysql.dll there and only there.

TOAD versus DBVisuzalizer

Earlier this year I began working with Microsoft SQL Server for the first time. Until now I’ve always been in open source databases, either MySQL or PostgreSQL.

At the time I looked around for a SQL Server-specific tool that simplified the process of sorting through table data (basic column sorting, filtering and the like), since SQL Server Studio seemed to focus primarily on managing query results. I tried a couple of tools like EMS’ SQL Manager, but nothing really stood out. Nothing worth paying for at least.

In the end I went back to my old standby, Minq’s DBVisualizer, which I’ve been using on-and-off since it was released back in ’99. It’s extremely convenient to have all one’s working databases, no matter the server, accessible from a single DBVis interface.

Recently, however, an Oracler tipped me off to Quest Software’s Tool for Application Developers (TOAD). Somehow all my googling last spring didn’t turn this up. Despite being a bit sluggish for a native Windows app, so far TOAD seems to be considerably more powerful the DBVis. I’m just scratching the surface, but TOAD’s inline editing of data is certainly more transparent, and includes nifty little touches like a popup calculator for numeric fields, date selectors, etc. The “group by column” feature is especially handy. Searchable built-in knowledgebase is a godsend for folks jumping back and forth between databases. The built-in session monitor is enlightening.

I’ll post more as I explore TOAD’s built in functionality, which seems to include a host of data differs, graph generation, and report designers.

I still wish I could view all my databases from a single dashboard — TOAD has different versions per database. But if you’re working in Windows, and spend a lot of time sifting through and managing data, then I have to say that TOAD has DBVisualizer beat hands down. Certainly worth the price of free.
