DataScript Constructs : Operators

DataScripts rely on the Lua scripting language for the syntax and supported usage of arithmetic, relational and logical operators. Operators compare or contrast datasets and will return true or false. When evaluating strings, DataScript is case-sensitive, so a does not equal A.

Arithmetic Operators

Operator	Meaning
+	Addition
-	Subtraction
*	Multiplication
/	Division

Relational Operators

Operator	Meaning
>	Greater than
<	Less than
>=	Greater than or equal to
<=	Less than or equal to
==	Equal to
~=	Not equal to

If the port does not equal to 443, then redirect the client to HTTPS.

if avi.vs.port() ~= "443" then
   avi.http.redirect("https://" .. avi.http.hostname() .. avi.http.get_uri())
end

Logical Operators

Operator	Definition
and	Returns true if both datasets are true
or	Returns true if either of the datasets is true
not	Returns true of the first dataset is not true
string.find	Used to search for a string within another string
