Operators Overview
- reference
Operators perform a specific operation on the input values or expressions.
SQL++ provides a full set of operators that you can use within its statements. Here are the categories of SQL++ operators:
-
Arithmetic Operators to perform basic mathematical operations (such as addition, subtraction, multiplication, and divisions) on numbers.
-
Collection Operators to evaluate expressions on collections or objects.
-
Comparison Operators to compare two expressions.
-
Conditional Operators to evaluate conditional logic in an expression
-
Construction Operators to construct arrays and objects.
-
Logical Operators to combine operators using Boolean logic.
-
Nested Operators and Expressions to access nested elements and embedded arrays.
-
String Operators to concatenate two expressions.
Operator Precedence
SQL++ supports the use of parentheses to group operators and expressions. Expressions enclosed in parentheses are evaluated first.
The following table shows operator precedence level. An operator at a higher level is evaluated before an operator at a lower level.
