5.4.7 Operators in Filter Expressions
Table Operators in filter expressions lists all operators which can be used in filter expressions.
| Operator | Description | Example |
|---|---|---|
| == | Equal | VALUE == 100 |
| <= | Less or equal | VALUE <= 100 |
| >= | Greater or equal | VALUE >= 100 |
| != | Not equal | VALUE != 100 |
| < | Less | VALUE < 100 |
| > | Greater | VALUE > 100 |
| ~= | Contains, case-sensitive | TEXT ~= "abc" |
| ?= | Contains, case-insensitive | TEXT ?= "abc" |
| *= | Contains, regular expression | TEXT *= "(abc)+" |
| || | Or | TEXT ~= "abc" || TEXT ~= "def" |
| && | And | TEXT ~= "abc" && TEXT ~= "def" |
| () | Group | (TEXT ~= "abc" || TEXT ~= "def") && TEXT ~= "ghi" |
| & | Escape | TEXT ~= "&"" |
| %n | String parameter | TEXT ~= %1 |
| %nd | Integer parameter | TEXT < %1d |
| %nf | Float parameter | TEXT < %1f |
| String value | TEXT ~= "abc" | |
| Integer value | VALUE == -100 | |
| Float value | VALUE == 100.0 | |
| Mapped value | TYPE == Error | |
| Null value | TYPE == NULL |
The operator precedence in filter expressions is the same as in the programming languages C++.
