Hi,
How do I know if a function (or a certain sql syntax) in Postgres is a SQL ANSI Standard, hence it works on all databases such as MySQL, SQL Server, Oracle. I noticed that concat, decode, nvl, instr are functions that work for some databases and don't for others. I only want to use ANSI Standard functions that work everywhere. How do I identify them? How do I know if a function is specific to Postgres and don't work for other databases. Sorry, I may have asked the same question more than a time But I just wanted it to be clear I'd appreciate any reply to my question Thanks Pascal
