What do you like best?
I like that SQL Anywhere is an enterprise database system and there is a lot of support and documentation available on the Internet.
I do come from a SQL Server background but I've found SQL Anywhere pretty easy to get used to, with only minimal help needed online.
What do you dislike?
The tools are poor!
Seriously, in the Interactive SQL editor you cannot highlight a portion of text and only execute that. If you have other queries in the same editor window, highlighted or not, it will try to run them.
It shows numbers with commas in them by default - but not everything is money, SAP - what about primary key ID fields? They look weird with commas.
Interactive SQL and Sybase Central will both remember previous hostnames but not credentials. You can't effortlessly save logins for re-opening.
Ultimately, I can't really recommend the tools at all ... find a better third-party solution ...
Recommendations to others considering the product
Find a good third-party SQL tool.
What business problems are you solving with the product? What benefits have you realized?
We didn't implement SQL Anywhere per se, it comes as the database used by a product we use, so I am administering it as a consequence of that.
However, the business problem in general was for a line-of-business app and we selected the one we did partially because it used a proper enterprise database engine.
