Syntax

<Result> = <Element used>.FilterWithBounds

<Result>: Boolean

True if bounds have been specified for the filter with HFilter,
False otherwise.

<Element used>: Character string (with or without quotes)

Name of the HFSQL data file, query or view on which the filter was defined.

Remarks

Values of bounds

If bounds have been defined, their values are returned by MinValue and MaxValue.

Reminder: hMinVal and hMaxVal used in a filter

To implement a generic filter on a value, you must:

fill the lower bound with the hMinVal constant to give it the minimum value.
fill the upper bound with the hMaxVal constant to give it the maximum value.

For example, to select the customers whose last name starts with "Smith":

HFilter(Customer, Name, "Smith" + hMinVal, "Smith" + hMaxVal)

The customers named "Smith" and "Smither" are selected.

See the help about HFilter for more details.
