Description
Given two or more parameters, the
min() function will
return the parameter with the smallest value. If any parameter
is a NULL, a NULL will be returned. Otherwise, numeric types
(mixed integers and floating-point) are considered smallest,
sorted together in their natural order. These are followed by
text values, which are followed by BLOB values.
If you want the comparison to use a specific collation, use a
COLLATE expression to
attach an explicit collation to the input values. For example,
min(
.param1 COLLATE NOCASE,
param2
)
There is also an aggregate version of min() that takes a single parameter.
