Returns the negated value of expr. This function is a synonym for negative function.
Syntax
- expr
Arguments
expr: An expression that evaluates to a numeric or interval.
Returns
The result type matches the argument type.
For integral numeric types the function can return an ARITHMETIC_OVERFLOW error.
warning
In Databricks Runtime, if spark.sql.ansi.enabled is false, an overflow does not cause an error but “wraps” the result instead.
Examples
SQL
> SELECT -(1);
-1
> SELECT -(cast(-32768 AS smallint));
Error: ARITHMETIC_OVERFLOW
> SELECT -INTERVAL '5' MONTH;
-0-5
