Questions tagged [notin]

The NOT IN predicate acts opposite to the "IN" predicate. It can be used to specify multiple values that should NOT be present in a WHERE clause. Note that NOT IN never is true!

NOT Logical Operator

If you want to find rows that do not satisfy a condition, you can use the logical operator NOT. NOT results in the reverse of a condition. That is, if a condition is satisfied, then the row is not returned.

NOT IN can be represented as conjunction of NOT equal comparison operators.

A NOT IN (B, C) <=> (NOT A=B) AND (NOT A=C) If one of A or B is NULL, then NOT IN is not True (Undefined)

MSSQL NOT

IN Predicate

The IN predicate is used when you want to compare a column with more than one value. It is similar to a number of equals comparisons OR-ed together.
