MIN

Syntax

MIN([ DISTINCT | ALL ] expr) OVER (analytic_clause)

Description

Returns the minimum value in the specified data.

The MIN() function can take a string parameter, in which case it returns the smallest string value.

• The DISTINCT keyword specifies to find the minimum value among distinct values of expr. However, the result is the same as if DISTINCT were omitted.

• The ALL keyword specifies to find the minimum value among all values of expr. The default is ALL.
