Once you have provisioned a SQLDB database service on Bluemix and launch the administration console, you are greeted by the "Getting Started" screen prominently featuring the following three choiced:
|IBM SQL Database: Getting Started|
The "Run Queries" button is intended to perform SQL SELECTs, nothing else.
Trying to issue "ALTER TABLE" statements results in an error. As the title suggests, "Work with Tables" is the option to choose. It takes you to a simple interface as shown below:
|IBM SQL Database: Work with Tables|
|IBM SQL Database: Table Definition|
|IBM SQL Database: Create a new table|
|IBM SQL Database: ALTER TABLE completed|
It is not the nicest way to alter a table and not really straight-forward. With the SQLDB service evolving, probably there will be GUI enhancements coming in the near future. If you don't want to wait or don't want to hook up another database client to your SQLDB database on Bluemix, the workaround described above lets you quickly modify the table structure.
