Question:
How difficult is it to convert a Sybase Transact-SQL database to SQL/400, and where can I find information on SQL/400?
Answer:
I don’t know but, in the main, learning syntax is a question of exploiting the vendor’s extensions, so if you know SQL, you’re already 75 percent of the way there.
There are some idiosyncrasies to these products (like Oracle seems to be happier with cursors than SQL Server, and you’ve got TOP and ROLLUP and COMPUTE BY etc.), so each flavor has its strengths and weaknesses.
