Humpty Dumpty Jumped Over The Wall

This blog / website runs on WordPress. An excellent software for people like me who want to focus on the content and leave presentation to a templated system. Whenever WordPress prompts me to update the software, I do not procrastinate the update; having learned it the hard way.

So a few days back when I was prompted to update to WordPress 3.2, I promptly clicked on the ‘Update Automatically’ button only to be be stumped! Turns out that my blog was running on MySQL 4.x database and WordPress 3.2 requires MySQL 5.x database.

I created another MySQL ver 5.x database so that I could copy the data from the existing database into it. Transferring the data turned out to be quite a challenge.

I did not want to use WordPress’s inbuilt Export / Import Tools since these tools work great for backing up and restoring articles and comments but fail to backup other tables in the database such as Users, Plugin settings etc. For that you need to Export / Import the database.

My blog is hosted at GoDaddy. Exporting the database using PhpMyAdmin tool provided by GoDaddy was easy enough. I exported the database in SQL format and downloaded it in ZIP format. The resulting 10.3 MB SQL file was compressed into 1.31 MB ZIP file by the web-server and downloaded to my PC.

Importing it back into the MySQL 5 database using PhpMyAdmin was the next big stumbling block. Turns out PhpMyAdmin on GoDaddy only allows importing of SQL files under 1 MB in size (mine was 10.3 MB). The interface claimed to support ZIP files.

So how do you import a 10.3 MB SQL file into a system that only allows 1 MB files?

Brilliant Idea #1:

Break the extracted SQL (10 MB) file into 2 parts (must break intelligently. Do not just use a splitting tool). ZIP up the parts (should come to approx. 500 KB ZIP file per part). Upload the ZIP files into the PhpMyAdmin Import functionality. Turns out, the Import function does not support ZIP files after all. Breaking the 10 MB file into 10 smaller SQL (uncompressed) files (and uploading them one at a time) was not an option I was even willing to explore.

Brilliant Idea #2:

Download a MySQL Administration Client on my laptop. Connect the client to the online database and upload the data from my PC. Turns out, GoDaddy does not allow a desktop client to connect to the databases on their systems. Though the databases appear to be on public IP, the databases only allow connects from their approved list of IPs.

Brilliant Idea #3:

Install an alternate PHP MySQL Admin Client in my web hosting space. One that does not have 1 MB import limitations. Turns out, researching SourceForge for suitable MySQL clients is really tough. My frame of mind was to discover a super quick fix; not get into legitimate research.

Fail Fail Fail.

Then it stuck me: why try to use packaged software when probably a line or two of PHP code could do the job? And I found just the right code on Google on my first try.

passthru("nohup mysql -h my-godaddy-database-host -u my-database-username -pMy-database-password < my-exported.sql");
echo("Done importing data.");

Using FTP, I uploaded this PHP file (I had saved the code as updatedb.php) and the SQL file (my-export.sql). After upload, I simply called the PHP file ( and less than a second later, the message on my screen was ‘Done importing data’. If you are going to use the code above, remember to change “my-… ….” details with the correct details as required by your web-host.

Next I downloaded and opened wp-config.php from my WordPress installation and changed the Host, Database, User, Password details in it to reflect the new MySQL 5 database. I uploaded the file back (overwrite the older one) and voila!

My blog was running off the new database. Heck, I even nuked the old database from GoDaddy just to be sure.

I updated the installation to WordPress 3.2 in a jiffy and hope that I shall be able to continue to do so until Version Number demons come calling again.

  1. Hi Rajib,

    I found your Tip & Tricks blogs quite useful especially the LCD one.

    I am thinking about purchasing a new TV set and needed opinion from someone who really knows the difference between an LCD & LED.

    Can you please help me out as to which one would be the best fit for me.
    Reading your article few of the things i could make out is i will need a 32 to 40 inch wall mountable set which will be on for almost 12 hours a day. (You see my parents are both pensioners and their only source of entertainment is this TV set and the PC.) Based on the requirements will you be able to advise. I think i will prefer either Sony or Samsung.



    • Dear Joji Abraham,

      Glad I could clear your doubts about the difference between LCD and LED TVs.

      Recently I was considering upgrading my 32″ LCD to a 46″ LCD. In the process I again checked out all the brands in the market, their picture quality, feature-set and price.
      IMHO, Sony TVs had the biggest hype but did not deliver the goods. The picture quality was ok but TV features were very minimal and price was very high when compared to competition.
      Panasonic picture quality was the best the TV designs are still like their 2 year old designs. Also Panasonic did not come first in the feature set comparison.
      Between Samsung and LG, I preferred the LG picture quality, feature-set and price, but as they say – quality and price are inversely related.
      I disregarded Philips (no new models, rumour of getting out of LCD TV business), TCL / Onida (no TVs in the range I was looking) and ignored VideoCon.

      Did I buy the 46″ TV? No. I was looking for a Full-HD TV with 100Hz – 200Hz picture refresh in a TV costing less than 50K. Unfortunately, the LG that came nearest to my requirement was an LED model and it was priced at 66K. So I think I will wait till the LED buzz dies down and manufacturers start charging the real-price of LED TVs.


  2. So Rajib, what i understand is its better to wait for LED prices to come down coz the market is charging more than what an LED is worth.

    But can you provide some details around how an LED is an improvement over an LCD say …performance-wise, energy efficiency wise etc.

    Appreciate your help.


    • Dear Joji,

      Electronic prices will keep coming down but you cannot wait forever since something new and desirable will always be priced at a premium.

      If you visit any store, you will find that LED Backlit TVs (falsely called as LED TVs) tend to have brighter and more vibrant images when compared to CFL Backlit TVs (generally known as LCD TVs). This is due to the high-intensity white light of the LED Back-lighting array when compared to the softer light of CFL tubes. Hence strictly speaking, LED TVs improve in performance over LCD TVs only in increasing the color-gamut slightly. Energy efficiency is bound to increase due to LED technology too but it is generally not enough for manufacturers to use it as a selling point.

      If you are looking or a TV that brings out oohs-aahs from visitors to your house, get a LED TV. It is still considered a lifestyle electronics. If you simply want a flat-panel TV, get a LCD TV because these are now available at great prices and offer a very very good viewing experience. My Panasonic 32″ LCD TV is connected to a Tata Sky HD+ box and when I watch NatGeo-HD or Discovery-HD on it, it is always a pleasure.
