COS Expression
What is COS Expression? Is the related to SQL Expression?
Can you give a basic code or query related samples? If anyone give a sample, it's understanding easily.

The COS docs have this nice explanation with examples.
COS = cache object script, a programming language
Like in pretty much all programming languages, an expression is something that can be evaluated/resolved to some value.
