Re: JSON document fast lookup with MySQL 5.7

This is a response to the JSON document fast lookup with MySQL 5.7 article by Frederic Descamp.

It is very easy to also use MySQL Workbench and the new GeoJSON support to actually show the features.

My query:
SELECT ST_GeomFromGeoJSON(feature->"$.geometry",2) AS feature 
FROM test_features WHERE street='BEACH' ;

The result:

 

MySQL Workbench on RHEL6

Yesterday I blogged about some issues with MySQL Workbench. The problem was that CentOS 5.5 is not supported.

So I installed RHEL6, one of the best known Enterprise Linux distributions. It's a 30 day evaluation, but that should be sufficient.

After some minor issues with VirtualBox I had a working installation. So I tried to install MySQL Workbench again. I used 'sudo yum localinstall mysql-workbench-gpl-5.2.31a-2el6.x86_64.rpm' which failed because of 2 unmet dependencies: pexpect and libzip.so.1

There is already a bug report in RHEL for the missing pexpect: #652659
I used the RHEL6 installation DVD to install pexpect.

There is a closed/wont-fix bug (#54403) for the libzip.so.1 dependency. It turns out that libzip is in the "RHEL Server Optional" channel. RHN should be used to enable more channels, but apparently the optional channel is not part of the evaluation license, so I used the web interface to download and install the libzip RPM.

The workbench installation finaly completed after complaining that the workbench rpm is not signed (use --nogpgcheck).

So I started MySQL Workbench (There is a launcher in the menu). And then I clicked the "MySQL Doc Library" and Workbench responded with an error about a missing package: pysqlite2/python-sqlite2. I could find a python-sqite for RHEL5 on RHN... but nothing for RHEL6. So I filed Bug #60336…

MySQL Workbench on CentOS

Every once in a while I use MySQL Workbench. First is was only for Windows, then it was unstable and now it is very well usable. Or at least that is the situation when you run on a recent Ubuntu machine.

I'm now using CenOS 5.5 in a VirualBox VM to do some testing. Unfortunately the download site for MySQL Workbench has RPMs for RedHat 6 and Fedora Core 14 and some other platforms. No CentOS, No RHEL5, only the latest Fedora en RHEL.

So I downloaded the RHEL6 RPMs and tried to install them with yum localinstall, but that failed. So they are not backwards compatible with 5.5.

Turns out that CentOS/RHEL 5 doesn't have the required libraries to support MySQL Workbench.

And unfortunately CentOS 5.5 is still the latest release. So an upgrade to CenOS 6 is not yet possible.
