This table shows the relative operators available for constructing a query clause.
| Operator | Description |
|---|---|
| = | The value of the attribute must be equal to the value of the constant. |
| != | The value of the attribute must not be equal to the value of the constant; however, the attribute must exist. |
| < | The value of the attribute must be less than the value of the constant. |
| <= | The value of the attribute must be less than or equal to the value of the constant. |
| > | The value of the attribute must be greater than the value of the constant. |
| >= | The value of the attribute must be greater than or equal to the value of the constant. |
| match | The value of the attribute must match a value of the constant, where the constant can include the wildcard characters "*" and "?". The wildcard "*" matches any number of missing characters and the wildcard "?" matches a single missing character. The match operator is case-sensitive. You can use the wildcard match only on the first 63 characters of an attribute. |
| !match | The value of the attribute cannot match any of the possible values of the constant. |
| smatch | The value of the attribute must match a string. The smatch operator is case-sensitive. |
