Returns the negated value of expr. This function is a synonym for - (minus sign) unary operator.

Syntax

negative(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.
