Overview
Not present in a list.
USAGE
check NOT IN (value[, ...]);
check NOT IN (SELECT ...);
Value Name | Description |
|---|---|
| A value expression |
| One or more value expressions separated by commas |
| A SELECT that returns single-value rows |
DETAILS
The NOT IN operator allows you to match an expression against multiple values, returning a truth value indicating if the check value does not match any of the list values.
The operator's arguments can consist of a literal list of values to match (separated by commas) or it can be a SELECT that fetches the list of values (one value per row).
In the first syntax, using var NOT IN (1, 2, 3) is easier to write than (var != 1 AND var != 2 AND var != 3).
The non-negated version is available as the IN operator.
