Re: SQL Differences

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

Hi Adam

This is a really broad and vague question - what language will it be 
written in? Which RDBMS will be used (Oracle, SQL Server, etc.)? Web app 
or local app? Will it be talking to the i, or is the i being replaced? I 
don't know, all kinds of questions.

SQL is SQL is SQL, for the most part. There will be some syntax 
differences, but, as Charles said, simple things are the same. You need 
to adjust for whatever flavor of SQL you use for some things - for data 
types, e.g. Another example is, on the i you can use substr() - on SQL 
Server you have to use the entire word substring() - that also works on 
the i, so if you want portability, you use the whole word.

Stored procedures could be an issue, but I doubt you are going that way. 
They are the "programs" of SQL database systems.

We have a product, a software development kit, actually - that lets you 
work real-time with other SQL database systems - not a plug - heh. The 
thing is, I have to find the right syntax for those other systems. For 
SQL Server I will use what used to be called the Query Analyzer - it's 
part of their management interface now. I try something, I test, I read 
the help text, I get the answers.
