MIN

Description

The MIN function finds the minimum number or date in a subform's field or in two or more fields.

Usage

MIN(VALUE1, VALUE2, VALUE3, ...)
MIN(SUBFORM_FIELD.FIELD_NAME)

Remarks

When used with subform fields, the argument to MIN() must include a reference to the form's subform field and then the field within the subform, using the dot notation.

The MIN function accepts arguments with the following types:

  • Number
  • Text
  • Instant
  • Date
  • Week
  • Month

When comparing text, the comparison is case sensitive. That means that "ABC" does not equal "abc".

Examples

Check for presence of children in a household

If you have a household survey form with a "Members" subform, you can use the MIN function to find the minimum age of the members. You can use this as part of a relevance rule to show some questions that are only relevant if there are children in the household:

MIN(MEMBERS.AGE) < 18

Find the first of two dates

If you have a form with two date of fields, such as SCHOOL_ENROLLMENT_DATE and PROGRAMME_INTAKE_DATE, you can find the date that occurred first using the MIN function:

MIN(SCHOOL_ENROLLMENT_DATE, PROGRAMME_INTAKE_DATE)
